The Outcome and Most Emblematic Decisions Taken by the 50th Session of the Codex Alimentarius Committee on Food Additives
This article originally appeared in WorldFoodRegulationReview.
The 50th session of the Codex Alimentarius Committee on Food Additives (CCFA50) has completed its full agenda and found consensus on many new food additives provisions, which has reduced significantly the backlog from past years on miscellaneous food additives, with a good perspective to complete this task at its next session (almost two years ahead of schedule). And, against all odds, CCFA50 agreed for the first time since 2012 to work on a handful number of colour additive provisions in a limited number of confectionery categories for possible adoption as of the 2019 CCFA51 session (i.e. part of the GSFA mandate) as a test case for all the colour pending provisions. The Committee also modernised some of its internal procedures – and relations with JECFA – to speed up future work. CCFA50 seems to have slightly changed its mind about enzymes since last year and agreed to give a higher consideration to enzymes in the future, especially for their review by JECFA. The Committee also endorsed internal guidelines with other Codex Committees on the crucially important alignment between food additives provisions in the GSFA1 and those approved in Commodity Standards. As a good example, CCFA50 has completed the alignment work for fish and fishery products standards fully, and in the future, it will also rely more on active Codex commodity committees to perform such an alignment task. Last but not the least – and totally unexpectedly –CCFA50 agreed to start again the discussion on Note 161 related to some provisions on intense sweeteners, where left unanswered three years ago
Mr Christophe Leprêtre2
The 50th session of the Codex alimentarius Committee on Food Additives was held in Xiamen (China) from 26 to 30 March 2018, preceded by a two-day pre-session working group in person (PWG) to advance recommendations to the CCFA50plenaryontheGSFA.CCFA50alsoheld3 in-session working groups to advance recommendations to CCFA50 plenary on Alignment, the INS and class names of food additives, and priorities assigned to JECFA for safety evaluation, specification reviews among other tasks.
“CCFA 2.0”: Yes indeed, but practical implementation should be tested
The discussion held on the last afternoon of the plenary was deliberately oriented to consider those recommendations only as a common pathway for future ways of working, rather than to make clear-cut choices between the various suggested different options under each recommendation.
Therefore, all the expected debates fell quite short and many written comments submitted were not raised in plenary, except for the key countries (China, EU, Australia, Canada, USA, New Zealand) and only from a handful number of observer organisations.
• Note 161 – No battle, mainly due to absence of willingness to fight, this time…
The suspense was carefully kept until the very end of the plenary of CCFA50, as in any very good movie. And bang! The CCFA 50 did not discuss the Note 161 issue. Like a couple of magicians pulling out a peaceful white rabbit from a hat on stage, the USA and the EU4suggested that the Committee shall resume its discussions exactly where it left them three years ago, in reutilizing the report of an old electronic working group, led at that time by the UK on three intense sweeteners. For sure, such a concerted solution must have been subject to intense informal discussions, day and night, during the whole CCFA50.
Therefore, CCFA50 tasked an electronic working group (EWG) to review the 2015 EWG recommendations which classified selected sweeteners provisions in six batches; each of them offering a possible dedicated solution to replace the Note 161 with other existing notes (i.e. with no added sugars; energy-reduced; or a combination) or new notes. It should be mentioned that the past work did not cover all intense sweeteners provisions, but only those for aspartame, acesulfame K and the salt of aspartame-acesulfame, both already adopted (i.e. included in the published GSFA, alias CXS 192) and draft provisions (i.e. provisions in the step process)5.
Smiling moment: when the CCFA50 Chairman asks, who would like to chair this new EWG, then both the USA and the EU were prompt to offer their support – but both as co-chairs – as none seemed to be truly prepared to take the lead on this “hot potato” issue. Alike the (lack of) outcome of the CCFA47 negotiation in 2015, the situation looks like “even” – starting with this chairmanship issue. As pointed out by Germany though, a new spirit seems to have emerged within the CCFA delegations, so maybe this time solutions matching all the contradicting and polarized positions (including within the various industry sectors) may be found… At least, one reassurance: Note 161 issue is like a CCFA type of phoenix... It resuscitates and rises from the ashes. It is the second time in the past 10 years it does so. Future may tell, “what about this time?”
• Key factors to speed up the review process by the CCFA
• Reducing the time-lapse between draft entry in GSFA and final adoption
CCFA50 agreed that once it would agree to enter new (or revised) draft provisions for a food additive in the GSFA, such provisions would be immediately circulated to the CCFA community for comments and consideration at the immediate next session. At last! Indeed, this very simple solution is intended to alleviate the current uncertainty between entry into the GSFA of a draft provision and consideration by the CCFA for possible adoption.
Some provisions reviewed by CCFA50 this year have been waiting for 20 years before being considered. The new process flow may help ensuring more foreseeability, especially for new substances which were recently reviewed by JECFA. However, CCFA50 is somewhat conditioning the implementation of that decision to until after next year’s session. Who knows what may happen then…
• Decisions to help with the work on Alignment (between GSFA and Food Standards)
CCFA50 took several decisions and anticipated a little bit ahead of the new working procedure. The new working procedure would involve organisations representing technical expertise in a defined food sector. As such, and in line with another CCFA50 decision to ask the International Dairy Federation (IDF) to prepare the future background alignment work on alignment of food additive provisions for all ripened cheese standards, CCFA50 agreed to use further Codex observers for preparatory work, nominated Japan as co-chair of the regular inter-session EWG on alignment (chaired by Australia) and agreed to enhance the partnership with and the delegation of the preparatory alignment work to other active Commodity Committees (see more details on Alignment below). The European Union delegation indicated that Codex observer’s preparatory work will need to be scrutinize very carefully by Codex members (all country and EC representatives) to avoid any mismatch.
• Marginal decisions on the INS but important precisions a new policy rule
CCFA50 agreed to amend the general section of the INS (i.e. CAC/GL 36, now CXG 36) to add some precisions that the INS list may include names of substances not evaluated by JECFA (reminder) or that are not included in the GSFA (this is the new added text). As a consequential change and other recommendations adopted by CCFA50, the yearly Codex Circular Letter requesting comments on the INS is amended. It will now specify that any proposal for deletion of INS entries cannot be submitted if there are existing provisions (adopted or in the Step Process) for the additive in the GSFA with the understanding that the CCFA must first take a formal decision to remove those provisions from the GSFA prior to the submission of proposals to delete a corresponding INS entry.
• Prioritize new work for JECFA and other aspects
CCFA50 recognized almost unanimously that the primary key factor to review a substance (a food additive, including flavouring, and processing aids such as enzymes, all included in the Codex definition of “food additive”) was when it raises a food safety concern. Potential trade issues linked to “imperfect” specifications were also noted but the question may diverge about what “imperfect” is, as countries and industry groups may not have the same interpretation – nor the same needs – about that. But the discussion went in sequence: classical food additives (for inclusion in GSFA) and enzymes and flavourings (only covered by Codex Guidelines and where Codex only approved the specifications).
The Committee endorsed the recommendations included in the discussion paper but left open to give it a second thought soon. Therefore, the Committee is now giving the highest priority to re-evaluation of existing food additives should new safety concern(s) may arise. Then, it may consider on equal grounds the safety evaluation of new substances (including establishment of specifications) and the optimization of existing specifications.
Regarding food additives other than enzymes and flavourings, one observer reminded the Committee that the Committee already worked intensively – eight years ago – at a scoring screening system developed by Canada, with the help of multiple successive electronic working groups. This is based on a screening tool that the prioritization of colours for re-evaluation was established. It was pointed out that such a list was still the one used by JECFA to carry on with the re-evaluation program of such prioritized colours. It should be noted that many criteria were included in the screening score tool and that the date of the last JECFA evaluation was viewed as an important criterion, but not the only one to be considered and weighed. The tool was never further tested for other groups of food additives than colours.
Regarding the type of questions to be added to the Codex circular letter requesting comments for new JECFA work, the Committee tasked the JECFA secretariat and Codex secretariat to work on what improvement could be made for consideration at the next in-session WG on JECF A priorities (at the 2019 CCFA51). This work would certainly echo the decision already made by the Canada Chair during this session WG on JECFA priorities to populate more information about the various requests so that the information is not lost. It also echoes the JECFA/WHO statement about the additional requirements for naturally sources substances (e.g. plant extracts) in terms of chemical characterization and toxicological profiles. The two suggested options were retained as one covering flavourings and another one enzymes.
• Processing aids: no clear decision on a dedicated standard on all types of processing aids
CCFA50 recognised and stated again that the current database on processing aids – which is maintained up-to-date by the Chinese government with technical support from New Zealand expert – is not a Codex text nor a recognition of any type of the list of substances but rather a simple inventory. CCFA50 did not agree to develop a dedicated Codex standard on processing aids, despite the heavy support by New Zealand and Australia for the idea.
At minima, CCFA50 conceded that the current Codex Guidelines on Substances used as Processing Aids (CAC/GL75, i.e. CXG 75) may be reviewed/amended, as a future priority and not to be completed at this point in time. At the same time, many enzymes have been added to the priority list for JECFA safety evaluation and establishment of specifications (see further below). Last year, CCFA49 concluded that priorities assigned to JECFA needed to go first and foremost to food additives. Well, well, well…
Regarding how the Committee would decide upon the order by which priorities are set, the recommendation was discarded. While the EU called upon a more inclusive and transparent process for qualitative evaluation of the new work, Australia encouraged the Committee not to lose the core principles underlined by the priority order settings and urged the committee to develop a mechanism to address prioritization. But the Committee simply decided not to. This means that the current status quo may prevail, with marginal other changes made. Therefore, there is no real innovative approach on the go. And it is still not clear how all the other decisions made on the other recommendations will work out together towards the objective of the “One CCFA approach”.
GSFA pending provisions: landmark progresses made by CCFA, despite The Voice’s extinction and controversial debates on several key provisions on “other fluid milks (plain)” and “water-based flavoured drinks” (i.e. soft drinks)
A two-day CCFA50 pre-session working group (PWG) went through all pending GSFA provisions on its agenda (see WFRR Vol. 27, Number 9, Feb. 2018) and reviewed new proposals for inclusion of other draft provisions at Step 2. Mostly, it suggested to CCFA50 plenary provisions for (i) adoption, (ii) revision, (iii) discontinuation and (iv) revocation. CCFA50 plenary endorsed most of them. It is a spectacular result obtained by the Chair of the PWG, Dr Paul Honigfort (USA-FDA) and a landmark performance, given a painful voice extinction which made him suffer during the full duration of the debates. That result is also the expression of a new spirit of compromise blowing throughout all delegations, except on a few issues reported below.
(i) Draft and proposed draft provisions in the GSFA regarding the second half of food categories (from fish products to prepared foods)6; (ii) new provision for inclusion at step 2 in the GSFA or proposed revisions of already approved provisions in GSFA; (iii) Proposed draft provisions related to fluid milk (plain); (iv) Proposed draft provisions related to the recently created new food category on other fluid milk (plain)7; (v) Lutein esters from Tagetes erecta and octenyl succinic acid (OSA)-modified Gum Arabic proposed for inclusion in Table 3 of the GSFA(i.e. GMP use unless otherwise regulated); (vi) Some provisions in food categories subject to standardized foods on processed fruits and vegetables and edible oils.
It is virtually impossible to report here about each individual decision taken by CCFA50 based on the 250+ pages long working document. All CCFA50 decisions about each draft provision proposed for final adoption and inclusion in the published GSFA (subject to formal approval by the next Codex alimentarius Commission (CAC41, July 2018)) are included in Appendix V-Part A of the CCFA50 report.
The one provision proposed for revocation (by a CAC41 approval decision)8 is included in Appendix VI. The quite few new draft provisions introduced in the GSFA (at Step 2 and 3) are reported in Appendix VII; and draft provisions discontinued and to be deleted from the step process (decision enacted immediately) are included in Appendix VIII.
However, it may be of interest to note that several provisions did lead to some very interesting debates. The following have been identified as the most remarkable ones.
• Trisodium citrate in plain fluid milk
Although the pre-session working group on GSFA found compromise on permitting this food additive at GMP level in UHT milk from non-bovine species only, only as emulsifier and stabilizer, Brazil and New Zealand raised the need to add sterilized milk and maybe not add the restriction to other species then bovine (whereas the EU made clear that it is technologically justified in e.g. goat milk and not in bovine milk). Thus, the provision will be discussed again next year.
• Emulsifiers, Thickeners and Stabilizers in other types of plain fluid milks
This topic has led to harsh discussions both during the pre-session working group and the CCFA50 plenary. Members were split on the question whether the use of emulsifiers and stabilisers may be justified for use (i) in this full food category (i.e. all the fluids milks other than those covered by food category plain (unflavoured) fluid milk), or (ii) in recombined and reconstituted other fluid milk products only; and/or (iii) in non-flavoured other fluid milk fortified with vitamin and mineral only; and/or (iv) in other fluid milks such as protein-adjusted milk, lactose-low milk, etc.
Despite of the lack of consensus noted in the report on many of these issues, the provisions under consideration are proposed for adoption (by the next CAC41) with specific notes reflecting the debate additive by additive, “for use in non-flavoured vitamin and mineral fortified fluid milk only”9, “excluding lactose reduced milk”10, of with more specific level set as “Except for use in
The debate on the use of other food additives as emulsifiers and stabilizers in this food category was even more animated both during the pre-session PWG. The CCFA50 could only conclude about to a lack of consensus and did not endorse the PWG recommendation to recognise that those substances would generally be technologically justified for use in these types of fluids milks. Hence, all the provisions are retained on hold and it means that they will be re-discussed again one by one next year12.
• Soft drinks, “ADI” and a moment of palpable tension
Although most of the discussions went well on other provisions, one topic has led to vivid exchanges between delegations on some provisions considered both at the pre-session working group and the plenary.
Everything started badly with the consideration of a provision of 10 mg/kg of dioctyl sodium succinate (INS 480) in water-based flavoured drinks (i.e. soft drinks), including ‘sport’, ‘energy’ or ‘electrolyte’ drinks and ‘particulated’ drinks. The EU representative made clear that (i) with a low JECFA Acceptable Daily Intake (ADI) for that substance, (ii)with the current proposed maximum use level, (iii) and considering that if a 20 Kg-body-weight (very) young child would be drinking just a few centilitres of such soft drink containing that additive, it would easily lead to exceed the ADI13.
The same type of argument was used again by the EU for the provision for tocopherols (INS 307 a, b, c). But this time it triggered a chained reaction by USA, Canada, Australia and their allies of the day (Senegal, Chile, Colombia, South Africa, Kenya and Palestine, supported by ICBA and ICGMA) which denounced (i) a misleading argument as distorting what a proper exposure assessment should be, which would constitute a worrying precedent in CCFA proceedings; (ii) the concept of ADI (life-time exposure basis so focusing only on one age group is not relevant); and, (iii) that tocopherols were re-evaluated recently by the European Food Safety Authority and did not lead to safety concerns.
However, the EU representative indicated that the EFSA evaluation was referring to the use it as a vitamin and the health guidance value was a Tolerable Upper Limit but that, at the 95th percentile, the exposure to infants would lead to five times the ADI at the proposed 1000 mg/kg level. During the discussion, the JECFA secretariat was asked to check (i) when tocopherols (as well as other food additives considered for that food category) were reviewed for the last time and (ii) whether JECFA performed a dietary exposure assessment back then. The JECFA secretariat carefully indicated the last reviews were in 1986, 1975, 1976, 1973 depending on the food additives mentioned, and pointed that the JECFA role was limited to establish an ADI at that time and no exposure assessment was done by or requested to JECFA back then. (And let’s remember: GSFA started to be reviewed in its modern feature from the early 1990s only).
At another point of the discussion on the other provisions for this food category, the JECFA secretariat also indicated that if CCFA would decide to ask JECFA to performan exposure assessment for a given additive, it could be that JECFA experts will consider that the food additive in question may also deserve a re-evaluation (given the last date of review by JECFA) and they decide to revisit the food additive specifications to check new methods of production or simply put the specifications in line with others, adopted at national/regional level. That’s where the discussion was left in the PWG on GSFA before the plenary revisits the issue.
Hence, the CCFA50 report contains an unusually long paragraph (Para.91) which spells out very clearly the (still) divergent points of views expressed during the plenary.
In terms of the provisions, five are going through for final adoption (including the one on tocopherols but with a new note added to it referring to the fact that in this case tocopherols are secondary food additives – and wasn’t it the whole point of the EU to challenge the technological needs and justifications provided in the first place about the draft level proposed initially at 1000 mg/kg?)14, and 8 other provisions are discontinued (two at the express request of the soft drink industry as they are used as flavouring not flavour enhancers)15. Therefore, all ended up well. And CCFA50 finished its agenda smoothly.
GSFA work for 2018/2019: some colours are back on the work program
CCFA50 decided to establish a new EWG on GSFA to go overall the pending provisions for miscellaneous additives (except those subject to specific issues to be resolved such as adipic acid, nitrites, nitrates or feedbacks expected from other Codex commodity committees), but not only. The most astonishing breaking news is that the work program of the EWG on GSFA also includes, to the surprise of most of the participants, all pending provisions in the step process for colours in candies (hard and soft), marzipans and nougats, decorations to confectionery, and chewing gum, to start with. This is the first time in the past eight years, that CCFA has decided to place any colour provision on its work program, in the context of the GSFA itself. Indeed, discussions stopped on colour (and sweeteners) a couple of years ago, because of the growing use of Note 161 to get provisions approved. And then, the Committee focused primarily on Note 161itself, and then Note 161 on sweeteners (see above).
At that occasion and in the specific context of the new work on colours, an industry observer stated that it intended to “develop a constructive dialogue with all interested parties based on (i) sound science, (ii) state-of-the-art food technology, (iii) Codex alimentarius procedures, and (iv) the Preamble of the GSFA”. The observer further pointed out that the recent progresses made by the CCFA, not only at this 50th session, but also the three last. In this industry observer’s view, such progresses “were good for (i) consumer health protection, (ii) fair practices for foods in international trade and (iii) global harmonization of national and regional regulations and standards on food additives”. A round of applause concluded the statement and to thank the USA delegates (Chairing the EWG and PWG) and all the other delegations for their hard work in speeding up exponentially the progresses to reduce – and soon complete – the backlog of all pending provisions in the GSFA.
Other, more classic, CCFA50 decisions on Alignment, INS and JECFA list of priorities
Alignment: great achievement and one of the most important on going pieces of work
The revised provisions for aligning food additives permitted in Annexes to the Commodity Standard for Canned Fruits (i.e. mangoes, pears, pineapples) and all the Commodity standards for fish and fish products16. Those provisions aligned between the related food categories of the GSFA and each of the Commodity standards are included
in Appendix IV-Part A & Part B; Appendix V – Part B1&B2 of the CCFA50 report (pending CAC41 approval decision). All those commodity standards will accordingly be modified and republished during the second half of 2018 to reflect the changes.
CCFA50 adopted a very important working guidance document on alignment, included in Appendix XI of CCFA50 report. This document will be published as an information document on the Codex alimentarius website17. The working guidance also includes a flow chart decision-tree and further specific recommendations to the active Codex Commodity Committees to start thinking to help CCFA in the alignment process of food additives provisions in Codex food standards under their responsibility and the corresponding food categories in the GSFA. CCFA50 therefore agreed that commodity committees shall be informed about that document as well as all FAO/WHO regional coordinating committees which have developed regional standards in the last decade. They will also be informed about the alignment plan that CCFA has adopted at its 50th session, and specially request CCSCH, CCFO and CCPFV to consider prioritizing initial alignment of commodity standards within the scope of the next two years. The full plan includes all Codex food standards. The full completion of the work is expected by 202518.
CCFA50 also approved a revised approach on how listing the corresponding commodity standards in Table 3 of the GSFA after having verified its applicability for the GSFA-online posting and how the information could be managed in the GSFA overall database and published version of CXS 192.
CCFA50 also requested other Codex Committees to revoke the permitted use for some food additives with no JECFA specification (i.e. potassium hydrogen malate (INS 351(i)), potassium malate (INS 351(ii)), monosodium tartrate (INS 335(i)), monopotassium tartrate (INS 336(i)) and dipotassium tartrate (INS 336(ii)) in several Commodity Standards which they are responsible for.
Therefore, it can be concluded that the alignment work will be the most substantive part of the work of CCFA for the next years, with Australia and Japan as the leading countries, and with new help from specialised industry observer organisations, such as the International Dairy Federation (IDF) and the Codex Commodity Committees, now that the operating rules and working procedures have been approved by CCFA.
Review of JECFA past work, current recommendations for CCFA consideration and CCFA decisions on next priorities of work for JECFA in the next 2 years
As usual, CCFA reviewed the outcome of the most recent JECFA meeting on food additives (held in June 2017) and considered whether any action may be necessary. It is worth noting that JECFA has re-evaluated two colours (Brilliant Blue FCF and Fast Green FCF) and reaffirmed that both did not raise any safety concern in terms of exposure (even if the ADI has been lowered in one case). Meanwhile, CCFA50 agreed with JECFA recommendation that the Group ADI for all carotenoids may be re-evaluated in the light of the information provided about a new algal source of beta-carotene.
CCFA50 also adopted several new and revised JECFA specifications (i.e. adopted as “Full” by JECFA) for possible adoption as Codex specifications for food additives (i.e. as international standards)19. Two new specifications for Tamarind seeds polysaccharide (INS 437 – assigned by CCFA50 to be approved by CAC41) and Beta-Carotene-rich extract from Dunaliella salina (No INS assigned yet, but it is on the agenda of the EWG on INS – see below). CCFA50 also adopted full revised specifications for Brilliant blue FCF (INS 133); Fast Green FCF (INS 143); Silicon dioxide, amorphous (INS 551); Sucrose esters of fatty acids (INS 473); Microcrystalline cellulose (INS 460(i)); Gum ghatti (INS 419); Sodium aluminium silicate (INS 554) and Steviol Glycosides (INS 960). These changes are reflected in Appendix III of CCFA50 report.
CCFA noted – for information only – other specifications currently under JECFA review (i.e., called “Tentative” by JECFA), pending additional information is provided to JECFA for their finalisation (e.g. Jagua (Genipin–Glycine) Blue; Metatartaric acid (INS 353); and Yeast extracts containing mannoproteins).
Regarding JECFA list of priorities assigned at this CCFA50 session, the most remarkable change is the addition of many enzymes (used as processing aids) to the list of priorities. The other remarkable additions relate to several applicants request to consider new types of steviol glycosides obtained according to various techniques ranging from the use of genetically modified microorganisms, to bioconversion and biosynthesis. A new natural pigment extract named Black carrot extract, is also added All JECFA new priorities are reflected in Appendix X of the CCFA50 report. Moreover, it should be noted that the table has been populated with a more formalised list of information fields, at the initiative of the Canada chair, aiming at keeping records on details of the initial requests, previously only recorded in working documents uneasy to find back20. Those new fields will also be reflected in the Codex circular letter requesting comments on new JECFA priorities each January. In addition, a new Annex will be added to such circular letter to ask applicants/sponsor countries responsible for substances already under the review process by JECFA to confirm (i) the interest in pursuing with the application and (ii) they would comply with the announced deadline for data availability.
In that context, it is also worth noting that another very important amendment has been agreed to be added to the Codex circular letter at the request of the JECFA secretariat (WHO side). That amendmentisplacedundersection9ofthecircular letter about the “list of data available”. It reads as follows: “For substances obtained from natural sources, characterization of the products in commerce and a relevant set of biochemical and toxicological data on such products are essential for JECFA to develop a specifications monograph and the related safety, and such data/information could include: components of interest; all components of the final products; detailed manufacturing process; possible carry-over of substances; etc.”
The addition of this paragraph primarily reflects the strong views of risk assessment scientific experts in JECFA that the safety evaluation and establishment of specifications for substances from natural sources shall not substantially differ from what is required for substances obtained by other methods. Indeed, “natural” does not mean necessarily “safe”. Some plants or organisms are indeed containing very toxic elements, sometimes deadly at low doses. And the soft methods used to extract other interesting parts of such plants or organisms (such as natural colouring pigments) may not necessarily phase out those natural toxicants.
This addition approved by CCFA may be viewed as anecdotal, however it is a fundamental clarification. It should draw the attention of all companies having strategies or making ‘natural’ claims about concentrated colouring pigments, sold as “colouring foodstuffs” or “foods with
CCFA50 followed all the recommendations prepared by its in-session EWG on the INS21, chaired by Belgium due to absence of Iran representative
CCFA50 has adopted several changes to the Food Additive Class Names and International Numbering System (including functional classes and technological purposes) for food additives mostly based on the work done since last session through an inter-session electronic working group and new proposals put forward. CCFA50 did set-up
an in-session physical working group which tuned up further those recommendations into concrete proposals to the CCFA50 plenary for adoption.
The most important CCFA50 decision relates to Steviol Glycosides (i) to change the way Steviol Glycosides are numbered in the INS; (ii) what it means with regards to the provisions adopted in the GSFA and (iii) consequential amendments to the relevant Codex document listing adopted JECFA specifications.
Changes to steviol glycosides listing in the INS are included in Table 3 of Appendix IX-Part.A2 of the CCFA50 report. First change is that the entry corresponding to INS 960 becomes a parent category as “Steviol Glycosides” (therefore with no assigned functional class nor technological purpose for that parent category, as it becomes a “title” or class name of a broader family of food additives).
A new INS 960a is assigned to Steviol glycosides from Stevia rebaudiana Bertoni with possible synonym added in brackets “Steviol glycosides from Stevia”. That substance (which corresponds to the (only) one permitted in GSFA to date), is obviously a sweetener used for technological purpose as sweetener (i.e. for sweetening).
Another two new entries are introduced in the
INS. INS 960b is now a sub-parent category of Steviol Glycosides to describe all steviol glycosides obtained “from fermentation”. That number has no functional class nor technological purpose consequently. Under this sub-parent category, a new entry as INS 960 b(i) Rebaudioside A from multiple gene donors expressed in Yorrowia lipolytica is created as sweetener and for the technological purpose of sweetener (i.e. for sweetening). That approach looks quite new and may raise consistency questions across the overall INS system. But that’s what is proposed for final adoption at the next CAC41 this July.
Furthermore, CCFA50 decided that in the Codex text listing the Codex approved JECFA specifications for food additives (CAC/MISC 6 – CXM6), the two entries for INS960a and INS960b (i)would replace the current “Steviol glycosides” one. Consequential amendments are included in Appendix XI – Part B.
The other consequential decision taken by the CCFA50 is that all already approved provisions for Steviol Glycosides in the Codex GSFA will be applicable as a parent category entry into the GSFA to both new INS 960a and INS 960b (i), such as what is done for other food additives with a Group ADI and covered by a parent category (e.g. Phosphates). In concrete terms, it means that all the previously reviewed and approved use levels for Steviol Glycosides obtained by plant extraction from Stevia rebaudiana Bertoni will be also approved for Rebaudioside A from multiple gene donors expressed in Yorrowia lipolytica, as the maximum permitted use levels are expressed as steviol equivalent anyway.
Among other things, CCFA50 also approved other changes with a new functional class for (a) propylene glycol as a carrier and two corresponding technological purposes as carrier and carrier solvent, (b) mono- and di-glycerides of fatty acids, as glazing agent and surface-finishing agent, (c) gellan gum as a gelling agent and (d) DL-malic acid as a sequestrant. Potassium poly aspartate has been added to the INS with number 456 as a stabilizer, with the technological purpose being also as a stabilizer. As mentioned earlier, Tamarind seed polysaccharide was also assigned a new INS number 437 as an emulsifier, stabilizer, thickener and gelling agents with corresponding technological purposes, plus as “foam stabilizer”.
All the adopted changes are reflected in Appendix IX Part. A2 and B.
CCFA50 endorsed provisions for food additives adopted in the Codex standard for dairy permeate powders but not for the Near East Regional standard on Doogh, thus delaying very much the publication of the standard approved by CAC40 in July 2017
CCFA50 endorsed with no difficulty the limited food additive provisions of the Codex Standard on Dairy Permeate Powders (developed by correspondence). It should be noted that the standard also contains provision on processing aids.
However, CCFA50 was not able to find consensus on the food additives provisions enclosed in the Near East Regional Standard on Doogh based on the outcome of discussions held during the in-session working group on Endorsement and Alignment and the plenary. Indeed, this topic also led to very interesting discussions and a reminder about the relationship between Codex Committees elaborating commodity (i.e. food) standards and the GSFA when it comes to food additives.
Starting with the reminder, the USA reminded everyone, including the Codex secretariat, that on page 50 of the English version of the CAC Procedural Manual, “Should the commodity committee consider that a general reference to the General Standard for Food Additives does not serve its purpose, a proposal should be prepared and forwarded to the Committee on Food Additives for consideration and endorsement. The commodity committee shall provide a justification for why a general reference to the General Standard for Food Additives would not be appropriate in light of the criteria for the use of food additives established in the Preamble of the General Standard for Food Additives, in particular Section 3.” Based on this reminder, the CCFA did not get the technical inputs it needed to understand the technological needs for each of the individual provisions suggested in the standard.
It was recalled however that almost all food additives – but two (i.e. nisin and magnesium dihydrogen diphosphate) and the reference to national legislation were present also in the adopted international Codex Standard on Fermented Milk22, something that IDF tried to underline to the plenary.
IDF equally flagged out that there were transcription errors in the draft Regional Standard for Doogh, including in table 4.1 between heat-treated Doogh and heat-untreated Doogh compared to the Codex Standard on Fermented Milk. Japan also raised the issue of one type of Chlorophyllin which may need to be taken out from the list as not permitted in GSFA.
Finally, the USA indicated that the reference to national and/or regional competent authorities for the implementation of such provisions should not be present in such Codex standard and section on food additives, unless duly justified as well. Indeed, that reference seems to close to the wording of Note 161 found in the GSFA.
As a consequence of all of the above, CCFA50 did not endorse the food additive provisions in the draft Near East Regional Standard for Doogh and requested that the CCNE consider at its next session (a) whether a general reference to the GSFA was possible in place food additive provisions in the draft Regional Standard and if not to provide a justification; (b) assess the detailed comments provided by Japan in CCFA50 CRD31 and (c) reconsider the reference to national legislation set in the footnote(a) of the Table of Section 4.1 of the draft regional standard. Given the time by which the next CCNE may convene its 10th session (especially if after next CCFA51 in March 2019), the finalization and publication of the Regional Doogh Standard may be postponed by one to two years, as CCFA is to give its final say on the food additive section again. Maybe that’s something which may be fixed before then perhaps through a discussion to be held on the side of – or during – a forthcoming CAC meeting.
Discussion on nitrates and nitrites
CCFA50 considered the outcome of an EWG on the matter led by the Netherlands which came back with more questions than definitive recommendations for consideration by the CCFA.
Based on several interventions and clarifications from the JECFA secretariat (both FAO and WHO sides) on this issue, it was clear that there is obvious lack of clear-cut useful data, there is a thin line between what CCFA was doing on food additives and what CCCF was doing on contaminants regarding sources of dietary exposures to help JECFA refining all the aspects related to the risk(s) characterization, and a lack of visibility on the various risk management options. Based on that, CCFA50 agreed to task a new EWG chaired this time by the EU and co-chaired by the Netherlands to continue the investigation work and try to answer further some of the questions. More details are accurately reflected in paras. 94 to 104 of the CCFA50 report.
Discussion on further definitions of “plain”, “fresh”, “untreated”, “processed”, “unprocessed” (raw food or fresh food), “minimally processed (plain) foods”, “ultra-processed products” and possible related criteria for using food additives in them.
CCFA50 struggled a bit with the discussion paper prepared by the Russian Federation. Indeed, CCFA49 did ask the Russian Federation to prepare a document which would go into more details about Russia’s request to develop more precise Codex definitions about the terms “plain” and “unprocessed”, used and found in descriptors of the food categorization system included in the full GSFA (CXS 192). The discussion paper rather expanded the objective in trying to develop a set of new criteria to qualify, a priori, the suitability for the use of food additives in foods, depending on the level of processing they could have been subject to. Some countries were not in favour simply to continue working into that subjective direction, while others mentioned that what could be useful is to discuss the differences of concepts between “plain”, “fresh”, “unprocessed” and “untreated”.
CCFA50 tasked the Russian Federation to prepare a new discussion paper to review all existing Codex texts and identify where the terms “plain”, “fresh”, “unprocessed” and “untreated” were used and to what purpose to assess the feasibility and usefulness to develop definitions of these term, for the purpose of allocating food additive provisions to those foods qualified with those terms.
Next CCFA session
CCFA51 will be held in China from 25 to 29 March 2019 and preceded by a physical working group on GSFA and maybe on Alignment.
