The Panel on Food Additives and Flavourings added to Food (FAF) provided a scientific opinion re‐evaluating the safety of phosphates (E 338–341, E 343, E 450–452) as food additives. The Panel considered that adequate exposure and toxicity data were available. Phosphates are authorised food additives in the EU in accordance with Annex II and III to Regulation (EC) No 1333/2008. Exposure to phosphates from the whole diet was estimated using mainly analytical data. The values ranged from 251 mg P/person per day in infants to 1,625 mg P/person per day for adults, and the high exposure (95th percentile) from 331 mg P/person per day in infants to 2,728 mg P/person per day for adults. Phosphate is essential for all living organisms, is absorbed at 80–90% as free orthophosphate excreted via the kidney. The Panel considered phosphates to be of low acute oral toxicity and there is no concern with respect to genotoxicity and carcinogenicity. No effects were reported in developmental toxicity studies. The Panel derived a group acceptable daily intake (ADI) for phosphates expressed as phosphorus of 40 mg/kg body weight (bw) per day and concluded that this ADI is protective for the human population. The Panel noted that in the estimated exposure scenario based on analytical data exposure estimates exceeded the proposed ADI for infants, toddlers and other children at the mean level, and for infants, toddlers, children and adolescents at the 95th percentile. The Panel also noted that phosphates exposure by food supplements exceeds the proposed ADI. The Panel concluded that the available data did not give rise to safety concerns in infants below 16 weeks of age consuming formula and food for medical purposes.

The present opinion deals with the assessment of the data provided by interested business operators in support of an amendment of the EU specifications for titanium dioxide (E 171) with respect to the inclusion of additional parameters related to its particle size distribution. Titanium dioxide which is used as a food additive E 171 in food undergoes no surface treatment and is not coated. It consists of anatase or rutile generally containing small amounts of the other phase (rutile or anatase, < 2% m/m) and it may also contain small quantities (< 0.5%) of constituent particle growth and crystal phase control agents (alumina, sodium or potassium in combination with phosphate). Particle size analyses, by TEM, SEM, XDC or DC, have been carried out on five commercial brands of anatase E 171 and one of rutile E 171 manufactured by the only three EU manufacturers that, according to information submitted by interested business operators, produce food‐grade titanium dioxide. Interested business operators proposed to introduce in the EU specifications for E 171 a specification of more than 100 nm for median Feret min diameter and less than 50% of the number of constituent particles below 100 nm; measured by EM in both cases. The Panel, after reviewing the data, concluded that a specification of more than 100 nm for median minimal external dimension, equivalent to less than 50% of the number of constituent particles with a median minimal external dimension below 100 nm, should be inserted in the current EU specifications. The Panel considered that the conclusions made, and the uncertainties identified, in the previous EFSA assessments on E 171 remain valid. The Panel reiterates the need for the further research as recommended in the previous opinions in order to decrease the level of uncertainty and acknowledged that additional studies with characterised E 171 are being carried out by interested business operators.

The Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion re‐evaluating the safety of xanthan gum (E 415) as food additive. Following the conceptual framework for the risk assessment of certain food additives re‐evaluated under Commission Regulation (EU) No 257/2010, the Panel considered that adequate exposure and toxicity data were available. Based on the reported use levels, a refined exposure of up to 64 mg/kg bw per day in children for the general population, 38 mg/kg bw per day for children consumers only of food supplements at the high level exposure and 115 mg/kg bw per day for infants consuming foods for special medical purposes and special formulae (FSMPs), were estimated. Xanthan gum (E 415) is unlikely to be absorbed intact and is expected to be fermented by intestinal microbiota. No adverse effects were reported at the highest doses tested in chronic and carcinogenicity studies and there is no concern with respect to the genotoxicity. Repeated oral intake by adults of xanthan gum up to 214 mg/kg bw per day for ten days was well tolerated, but some individuals experienced abdominal discomfort, an undesirable but not adverse effect. The Panel concluded that there is no need for a numerical ADI for xanthan gum (E 415), and that there is no safety concern for the general population at the refined exposure assessment of xanthan gum (E 415) as food additive. Considering the outcome of clinical studies and post‐marketing surveillance, the Panel concluded that there is no safety concern from the use of xanthan gum (E 415) in FSMPs for infants and young children at concentrations reported by the food industry. The current re‐evaluation of xanthan gum (E 415) as a food additive is not considered to be applicable for infants under the age of 12 weeks.

The present scientific opinion deals with the evaluation of the safety of nisin (E 234) in the light of new toxicological data and with the proposed extension of use in unripened cheese and heat‐treated meat products. Nisin (E 234) is currently an authorised food additive in the EU under Annex II of Regulation (EC) 1333/2008 for use in several food categories. The safety of nisin (E 234) as a food additive has been evaluated in 2006 by the EFSA Panel on Food Additives, Flavourings, Processing Aids and Materials in Contact with Food, where an acceptable daily intake (ADI) of 0.13 mg/kg body weight (bw) was confirmed as previously established by Scientific Committee on Food (SCF). In addition to the studies previously evaluated by EFSA in 2006, the Panel considered in the present opinion, data from a new subchronic toxicity study. No adverse effects were observed in a repeated dose oral toxicity study in which rats were administered nisin A for 90 days. A no observed adverse effect level (NOAEL) of 225 mg nisin A/kg bw per day, the highest dose tested, was identified for this study. Using this NOAEL, an ADI of 1 mg nisin A/kg bw per day for nisin (E 234) was calculated applying a default uncertainty factor of 200 for extrapolation of subchronic to chronic exposure and inter‐ and intra‐species variability. The Panel calculated exposure estimates for both the current and the proposed uses based on the data available in the EFSA Comprehensive Database. The Panel considered that the overall exposure estimate was below the new ADI for nisin A for all population groups. The Panel concluded that the proposed extension of use of nisin (E 234) as a food additive in unripened cheese (at maximum level of 12 mg/kg) and in heat‐treated meat products (at maximum level of 25 mg/kg) would not be of safety concern.

The EFSA Panel on Food Additives and Flavourings (FAF) provides a scientific opinion on the safety of Monk fruit extract proposed for use as a new food additive in different food categories. Monk fruit extracts are prepared by water extraction of the fruits of Siraitia grosvenorii. Cucurbitane glycosides, mogrosides, are the main components of the S. grosvenorii fruit and mogroside V is the main mogroside in the Monk fruit extract. Mogroside V is absorbed to some extent and is systemically bioavailable. Monk fruit extract containing 25% and 55% mogroside V were negative in the bacterial reverse mutation assay and did not induce structural and/or numerical chromosomal damage. However, the Panel noted that the in vitro toxicity studies including study with metabolic activation were not sufficiently informative to evaluate the genotoxic potential of the metabolites generated after microbial metabolism, including the aglycone. The effects on the testis observed in a 90‐day study with monk fruit extract‐52% mogroside V cannot be dismissed and the adversity of these effects cannot be ruled out. No effects on parental, reproductive or development toxicity were observed in a reproductive and developmental screening study in rats. For male animals, the time of exposure did not cover the full length of spermatogenesis and, therefore, a longer term study at higher doses would be needed to clarify the effects on testes observed in the 90‐day study. No maternal and developmental toxicity was observed. Considering the systemic availability of mogroside V, the effects observed in the rat subchronic study and following the principles of EFSA Guidance on food additives evaluation, data from chronic/carcinogenicity toxicity testing would have been warranted. Exposure to mogroside V was calculated based on the proposed use levels. The Panel concluded that toxicity database on Monk fruit extract is insufficient to conclude on the safety of the use of Monk fruit extract as a food additive.

Indigo carmine (E 312) was re‐evaluated in 2014 by the EFSA Panel on Food Additives and Nutrient sources added to Food (ANS). The ANS Panel confirmed the acceptable daily intake (ADI) of 5 mg/kg body weight (bw) per day for indigo carmine allocated by JECFA (1975). The ANS Panel indicated that the ADI was applicable to a material with a purity of 93% pure colouring and manufactured using processes resulting in comparable residuals as material used in the Borzelleca et al. studies (1985, 1986) and Borzelleca and Hogan (1985) which were the basis for deriving the ADI. The ANS Panel considered that any extension of the ADI to indigo carmine of lower purity and/or manufactured using a different process would require new data to address the adverse effects on the testes observed in the Dixit and Goyal (2013) study. Following a European Commission call for data to submit data to fill the data gaps, an IBO submitted technical and toxicological data. Considering the technical data, the EFSA Panel on Food Additives and Flavourings (FAF Panel) recommended some modifications of the existing EU specifications for E 132, mainly to lower the limits for toxic elements. Considering the toxicological data, an IBO has submitted a 56‐day dietary study to address the adverse effects on testes using a material with 88% purity. The results of this study submitted did not confirm the severe adverse effects observed in the Dixit and Goyal study. Considering all the available information, the Panel confirmed the ADI of 5 mg/kg bw per day for indigo carmine (E 132) disodium salts, meeting the proposed revisions of the specifications (85% minimum for the colouring matter). The Panel concluded that there is no safety concern for the use of indigo carmine (E 132) disodium salts at the reported use levels and submitted analytical data.

In this opinion, the EFSA Panel on Food Additives and Flavourings (FAF Panel) was requested by the European Commission to carry out a scientific evaluation of an extended one‐generation reproductive toxicity study (EOGRTS) to determine whether it would allow reconsideration of the temporary group acceptable daily intake (ADI) for sorbic acid (E 200) and potassium sorbate (E 202), established by the Panel on Food Additives and Nutrient Sources added to Food (ANS Panel) in 2015. From the EOGTRS, the FAF Panel identified a lower confidence limit of the benchmark dose (BMDL) of 1,110 mg sorbic acid/kg body weight (bw) per day. By applying a default uncertainty factor of 100, the Panel established a group ADI expressed as 11 mg sorbic acid/kg bw per day for sorbic acid (E 200) and its potassium salt (E 202). In addition, European Commission asked EFSA to review a report on the ‘Stability of sorbic acid (E 200) and its potassium salt (E 202) during food processing and storage’ provided by industry. No new information was provided in this report, and therefore, in this opinion, there was no re‐assessment of the EFSA ANS opinion conclusions from 2015 regarding the stability of sorbates in food.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on L‐alpha‐glycerylphosphorylcholine (L‐alpha‐GPC) as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF subject of the application is L‐alpha‐GPC produced by chemical means starting from phosphatidylcholine (PC) enriched soya lecithin and is available in two forms: a viscous liquid GPC 85% and a powder Alpha Size 100P. The identity, production process, composition and specifications of the NF do not raise safety concerns. The NF is proposed to be used in food supplements at a maximum use level of 203.7 mg/day, corresponding to 82.5 mg/day of choline. The target population comprises individuals above 3 years of age, including pregnant and lactating women. L‐alpha‐GPC is an endogenous metabolite of phosphatidylcholine, is rapidly absorbed and serves as source of choline. The Panel considers that consumption of the NF is not nutritionally disadvantageous. The safety data in laboratory animals submitted by the applicant show several limitations; however, a no observed adverse effect level (NOAEL) of 1000 mg/kg bw per day for a 90‐day study and for maternal toxicity in a teratogenicity study could be derived from published studies. Based on the nature and absorption, distribution, metabolism and excretion (ADME) of the NF, the proposed use levels, the human data provided and the margin of Exposure (MoE), derived from the 90‐day study and the teratogenicity study, for children > 3 years of age (111) and for adults (345), which the Panel considers as sufficient in this case, the Panel concludes that the NF does not raise safety concerns under the proposed conditions of use.

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on 6′‐sialyllactose (6’‐SL) sodium salt as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is mainly composed of the human‐identical milk oligosaccharide (HiMO) 6’‐SL (sodium salt), but it also contains d‐lactose, sialic acid, 6′‐sialyllactulose and a small fraction of other related saccharides. The NF is produced by fermentation with a genetically modified strain (Escherichia coli K‐12 MG1655 INB‐6SL₀2) of E. coli K‐12 MG1655 (ATCC 700926). 6’‐SL (sodium salt) produced by fermentation with genetically modified strains of E. coli K‐12 DH1, E. coli BL21 or E. coli W is already authorised and included in the EU list of NFs. This application refers to a change in the production process and specifications, while the target population, conditions of use and consequently the anticipated intake remain unchanged. The information provided on the identity, production process, composition and specifications and the toxicological data of the NF do not raise safety concerns. The intake of other carbohydrate‐type compounds structurally related to 6’‐SL is also considered of no safety concern. In line with other HiMOs, the safety assessment of this NF is mainly based on the comparison between the intake of breastfed infants and the estimated intake of the NF. Given that the NF would be consumed to the same extent as the already authorised 6’‐SL (sodium salt), the Panel considers that the consumption of the NF at the proposed uses and use levels does not raise safety concerns. The Panel concludes that the NF is safe under the proposed conditions of use.

The present opinion deals with the re‐evaluation of alginic acid and its sodium, potassium, ammonium and calcium salts (E 400–E 404) when used as food additives. Alginic acid and its salts (E 400–E 404) are authorised food additives in the EU in accordance with Annex II and Annex III to Regulation (EC) No 1333/2008. Following the conceptual framework for the risk assessment of certain food additives re‐evaluated under Commission Regulation (EU) No 257/2010, the Panel concluded that there was no need for a numerical Acceptable Daily Intake (ADI) for alginic acid and its salts (E 400, E 401, E 402, E 403 and E 404), and that there was no safety concern at the level of the refined exposure assessment for the reported uses of alginic acid and its salts (E 400, E 401, E 402, E 403 and E 404) as food additives. The Panel further concluded that exposure of infants and young children to alginic acid and its salts (E 400, E 401, E 402, E 403 and E 404) by the use of these food additives should stay below therapeutic dosages for these population groups at which side‐effects could occur. Concerning the use of alginic acid and its salts (E 400, E 401, E 402, E 403 and E 404) in ‘dietary foods for special medical purposes and special formulae for infants’ (Food category 13.1.5.1) and ‘in dietary foods for babies and young children for special medical purposes as defined in Directive 1999/21/EC’ (Food category 13.1.5.2), the Panel further concluded that the available data did not allow an adequate assessment of the safety of alginic acid and its salts (E 400, E 401, E 402, E 403 and E 404) in infants and young children consuming the food belonging to the categories 13.1.5.1 and 13.1.5.2.
