The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion on the refined exposure assessment of extracts of rosemary (E 392) when used as a food ...additive. Extracts of rosemary (E 392) was evaluated by the AFC Panel in 2008. Following this EFSA evaluation, extracts of rosemary (E 392) was authorised for use as a food additive in the EU in several food categories with maximum levels. In 2015, the ANS Panel provided a scientific opinion on the safety of the proposed extensions of use for extracts of rosemary (E 392) in fat‐based spreads. In 2016, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated this food additive and established a temporary acceptable daily intake (ADI) of 0–0.3 mg/kg body weight (bw) for rosemary extract, expressed as carnosic acid plus carnosol. Based on the data provided by food industry, the Panel was able to refine the exposure estimates of extracts of rosemary (E 392). The highest mean refined exposure estimate (non‐brand loyal scenario) was 0.09 mg/kg bw per day in children (3–9 years) and the highest 95th percentile of exposure was 0.20 mg/kg bw per day in children. Taking uncertainties into account, the Panel concluded that these exposure estimates very likely overestimate the real exposure to extracts of rosemary (E 392) from its use as a food additive according to Annex II. Margins of safety were estimated for children and adults using the refined exposure estimate; these are higher than the ones calculated in 2015. Intake of carnosic acid and carnosol from natural diet (herbs) was estimated. It was maximally 1.66 mg/kg bw per day (p95).
The Panel on Food Additives and Flavourings (FAF) provided a scientific opinion re‐evaluating the safety of benzyl alcohol (E 1519) when used as a food additive. The Panel considered that adequate ...exposure and toxicity data were available. Benzyl alcohol (E 1519) is authorised as a food additive in the EU in accordance with Annex III to Regulation (EC) No 1333/2008. The Panel considered benzyl alcohol of low acute toxicity with no concern with respect to genotoxicity and carcinogenicity and established an acceptable daily intake (ADI) of 4 mg/kg body weight (bw) per day based on a no observable adverse effect level (NOAEL) of 400 mg/kg bw per day from the carcinogenicity study in rats. The mean and high exposure estimates in the refined exposure scenarios were maximally 0.27 and 0.81 mg/kg bw per day in toddlers, respectively. The exposure estimates to benzyl alcohol (E 1519) were below the ADI of 4 mg/kg bw per day in all population groups. The Panel noted that also the exposure in the regulatory maximum level exposure assessment scenario is below the ADI in all population groups. The Panel concluded that the exposure to benzyl alcohol (E 1519) does not raise a safety concern at the reported uses and use levels.
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.
The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion re‐evaluating the safety of propane‐1,2‐diol (E 1520) when used as a food additive. In 1996, ...the Scientific Committee on Food (SCF) established an acceptable daily intake (ADI) of 25 mg/kg body weight (bw) per day for propane‐1,2‐diol. Propane‐1,2‐diol is readily absorbed from the gastrointestinal and is expected to be widely distributed to organs and tissues. The major route of metabolism is oxidation to lactic acid and pyruvic acid. At high concentrations, free propane‐1,2‐diol is excreted in the urine. No treatment‐related effects were observed in subchronic toxicity studies. The available data did not raise concern with respect to genotoxicity. Haematological changes suggestive of an increased red blood cell destruction with a compensatory increased rate of haematopoiesis were observed at the highest dose level (5,000 mg/kg bw per day) in a 2‐year study in dogs. No adverse effects were reported in a 2‐year chronic study in rats with propane‐1,2‐diol (up to 2,500 mg/kg bw per day). The SCF used this study to derive the ADI. No adverse effects were observed in the available reproductive and developmental toxicity studies. Propane‐1,2‐diol (E 1520) is authorised according to Annex III in some food additives, food flavourings, enzymes and nutrients and it is then carried over to the final food. Dietary exposure to E 1520 was assessed based on the use levels and analytical data. The Panel considered that for the food categories for which information was available, the exposure was likely to be overestimated. Considering the toxicity database, the Panel concluded that there was no reason to revise the current ADI of 25 mg/kg bw per day. The Panel also concluded that the mean and the high exposure levels (P95) of the brand‐loyal refined exposure scenario did not exceed the ADI in any of the population groups from the use of propane‐1,2‐diol (E 1520) at the reported use levels and analytical results.
The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion re‐evaluating the safety of fatty acids (E 570) when used as a food additive. The food additive ...includes caprylic‐ (C8), capric‐ (C10), lauric‐ (C12), myristic‐ (C14), palmitic‐ (C16), stearic‐ (C18) and oleic acid (C18:1), present alone or in combination. In 1991, the Scientific Committee on Food (SCF) established a group acceptable daily intake (ADI) ‘not specified’ for the fatty acids (myristic, stearic, palmitic and oleic acid). The fatty acids (E 570) are absorbed in the same way as the free fatty acids from the regular diet. They show low acute toxicity. The available studies on subchronic toxicity were limited but there was no evidence for toxic effects at doses up to 10% in the diet (equivalent to 9,000 mg lauric acid/kg body weight (bw) per day). The Panel considered that the fatty acids (E 570) did not raise a concern for genotoxicity. Data on chronic toxicity, reproductive toxicity and developmental toxicity were too limited to reach a conclusion on these endpoints. The Panel noted that the contribution of fatty acids (E 570) represented on average only 1% of the overall exposure to saturated fatty acids from all dietary sources (food additive and regular diet). Based on the approach described in the conceptual framework for the risk assessment of certain food additives re‐evaluated under Commission Regulation (EU) No 257/2010 and taking into account the considerations mentioned above, the Panel concluded that the food additive fatty acids (E 570) was of no safety concern at the reported uses and use levels.
The Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion re‐evaluating the safety of guar gum (E 412) as a food additive. In the EU, guar gum was evaluated ...by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) in 1970, 1974 and 1975, who allocated an acceptable daily intake (ADI) ‘not specified’. Guar gum has been also evaluated by the Scientific Committee for Food (SCF) in 1977 who endorsed the ADI ‘not specified’ allocated by JECFA. 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. Guar gum is practically undigested, not absorbed intact, but significantly fermented by enteric bacteria in humans. No adverse effects were reported in subchronic and carcinogenicity studies at the highest dose tested; no concern with respect to the genotoxicity. Oral intake of guar gum was well tolerated in adults. The Panel concluded that there is no need for a numerical ADI for guar gum (E 412), and there is no safety concern for the general population at the refined exposure assessment of guar gum (E 412) as a food additive. The Panel considered that for uses of guar gum in foods intended for infants and young children the occurrence of abdominal discomfort should be monitored and if this effect is observed doses should be identified as a basis for further risk assessment. The Panel considered that no adequate specific studies addressing the safety of use of guar gum (E 412) in food categories 13.1.5.1 and 13.1.5.2 were available. Therefore, the Panel concluded that the available data do not allow an adequate assessment of the safety of guar gum (E 412) in infants and young children consuming these foods for special medical purposes.
The present opinion deals with the re‐evaluation of lecithins (E 322) when used as a food additive. Lecithins (E 322) is an authorised food additive in the EU according to Annex II and Annex III to ...Regulation (EC) No 1333/2008 on food additives, and have been previously evaluated by JECFA in 1973 and by the SCF in 1982. Among lecithins, phosphatidylcholine is hydrolysed in choline in the cytidine‐5‐diphosphate‐choline pathway in all cells of the body. 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 ADI for lecithins (E 322) and that there was no safety concern for the general population from more than 1 year of age at the refined exposure assessment for the reported uses of lecithins (E 322) as a food additive. The Panel further concluded that there is no safety concern for the exposure to the choline from lecithins (E 322) as a food additive at use and use levels reported by industry. For infants (from 12 weeks up to 11 months of age), the Panel concluded that there was no safety concern at the refined exposure assessment for the reported uses of lecithins (E 322) as a food additive and for the choline from lecithins (E 322) as a food additive at use and use levels reported by industry. For infants and young children consuming foods for special medical purposes, the Panel concluded that there was no safety concern with respect to the refined exposure assessment for the reported uses of lecithins (E 322) as a food additive and for exposure to choline resulting from these uses of lecithins (E 322).
The EFSA Panel on Food Additives and Flavourings (FAF) provides a scientific opinion on the safety of the proposed amendment of the specifications for steviol glycosides (E 960) as a food additive, ...in particular related to rebaudioside M produced via enzyme‐catalysed bioconversion of purified stevia leaf extract. Rebaudioside M (95% on dry basis) is produced via enzymatic bioconversion of purified stevia leaf extract using uridine diphosphate (UDP)‐glucosyltransferase and sucrose synthase enzymes produced by the genetically modified yeasts K. phaffii UGT‐a and K. phaffii UGT‐b, that facilitates the transfer of glucose to purified stevia leaf extract via glycosidic bonds. The Panel considered that the parental strain K. phaffii ATCC 20864 qualifies for the qualified presumption of safety (QPS) approach for safety assessment and, therefore, is considered to be safe for production purposes. The Panel concluded that there is no safety concern for Rebaudioside M produced via enzymatic bioconversion of purified stevia leaf extract using UDP‐glucosyltransferase and sucrose synthase enzymes produced by the genetically modified yeasts K. phaffii UGT‐a and K. phaffii UGT‐b, to be used as a food additive. However, the Panel recommended that the European Commission considers establishing separate specifications for Rebaudioside M produced via enzymatic bioconversion of purified stevia leaf extract in Commission Regulation (EU) No 231/2012.
Whenever new substances are proposed for use as sources of nutrients in food supplements, foods for the general population or foods for specific groups, EFSA is requested by the European Commission ...to perform an assessment of their safety and of the bioavailability of the nutrient from the proposed source. This guidance describes the scientific data required to allow an evaluation of the safety of the source within the established framework for risk assessment of food additives and novel food ingredients and the bioavailability of the nutrient from this source. This document is arranged in five main sections: one on technical data aimed at characterising the proposed source and at identifying potential hazards resulting from its manufacture and stability in food; one on existing authorisations and evaluation, providing an overview of previous assessments on the proposed source and their conclusions; one on proposed uses and exposure assessment section, allowing an estimate of the dietary exposure to the source and the nutrient based on the proposed uses and use levels; one on toxicological data, describing approaches which can be used to identify (in conjunction with data on manufacture and composition) and to characterise hazards of the source and any relevant breakdown products; the final section on bioavailability focuses on determining the extent to which the nutrient from the proposed source is available for use by the body in comparison with one or more forms of the same nutrient that are already permitted for use on the positive lists. This guidance document should replace the previous guidance issued by the Scientific Committee for Food and published in 2001.

The Panel on Food Additives and Flavourings of the European Food Safety Authority was requested to evaluate the genotoxic potential of flavouring substances from subgroup 3.2 of FGE.19 in the ...Flavouring Group Evaluation 215, Revision 1 (FGE.215Rev1). In FGE.215, the Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids concluded that the concern for genotoxicity could not be ruled out and requested in vivo data for the two representative substances 4-phenylbut-3-en-2-one FL-no: 07.024 and 1-(4-methoxyphenyl)pent-1-en-3-one FL-no: 07.030. The Flavour Industry has provided additional genotoxicity studies for both representative substances FL-no: 07.024 and FL-no: 07.030. Based on these new data, the Panel concluded that the concern for genotoxicity is ruled out for the representative substance FL-no: 07.024 and for the structurally related substances 4-phenylbut-3-en-2-ol FL-no: 02.066 and 3-methyl-4-phenylbut-3-en-2-one FL-no: 07.027 which can accordingly be evaluated through the Procedure in FGE.69. For the representative substance 1-(4-methoxyphenyl)pent-1-en-3-one FL-no: 07.030, the Panel concluded that FL-no: 07.030 is aneugenic in vitro. For such substances, there is currently no agreed follow-up strategy to finalise their safety assessment. The Panel is aware that the EFSA Scientific Committee is going to address this issue and a statement clarifying the assessment of in vitro aneugenic substances is under preparation. The Panel concluded therefore that, for the time being, the representative substance 1-(4-methoxyphenyl)pent-1-en-3-one FL-no: 07.030 and the structurally related substances vanillylidene acetone FL-no: 07.046 and 1-(4-methoxyphenyl)-4-methylpent-1-en-3-one FL-no: 07.049 cannot be evaluated through the Procedure. The Panel further concluded that 4-(2,3,6-trimethylphenyl)but-3-en-2-one FL-no: 07.206 is to be considered as a stand-alone substance due to the presence of the methyl groups, therefore, in vitro genotoxicity data were requested for FL-no: 07.206. Industry communicated that the evaluation of FLno: 07.206 is not supported any longer, therefore additional data were not submitted. (C) 2019 European Food Safety Authority.
