Refined exposure assessment of polyethylene glycol (E 1521) from its use as a food additive
The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion on the refined exposure assessment of polyethylene glycol (E 1521) when used as a food additive. Polyethylene glycols were evaluated by several international bodies and the AFC Panel previously adopted scientific opinions on the safety polyethylene glycol (E 1521). In 2006, the Panel concluded that based on all the data, consumption of PEG through use as plasticisers in filmâcoating formulations for food supplement tablets and/or capsules at the intended use level are not of safety concern. In 2007, in another opinion of the AFC Panel related to dâalphaâtocopheryl polyethylene glycol 1000 succinate (TPGS) in use for food for particular nutritional purposes, the Panel noted that TPGS intakes would correspond to intake to PEG 1000 at levels equivalent to 3.3â8.5 mg/kg body wieght (bw) per day which are within the range of group acceptable daily intakes (ADIs) of the SCF (1997) and JECFA (1980). This assessment could only take into account the use of polyethylene glycol (E 1521) in food supplements and thus the food supplements consumers only scenario was performed. It resulted in exposure estimates of polyethylene glycol (E 1521) up to 3.5 mg/kg bw per day at the mean and up to 6.1 mg/kg bw per day at the high level. The current exposure assessment is based on the methodology used in the reâevaluation of food additives together with reported use levels received following a call for data in 2017. Considering the uncertainties of the exposure assessment, these estimates very likely overestimated the real exposure to polyethylene glycol (E 1521). The Panel also noted that the highest calculated exposure estimate falls within the range of the group ADI previously established by SCF (5 mg/kg bw per day for PEG 300â4000) and of the one set by JECFA (10 mg/kg bw per day for PEG 200â10000)

Evaluation of diâcalcium malate, used as a novel food ingredient and as a source of calcium in foods for the general population, food supplements, total diet replacement for weight control and food for special medical purposes
The present scientific opinion deals with the evaluation of the safety of diâcalcium malate (DCM) proposed as a novel food ingredient and as a source of calcium for use in foods for the general population, food supplements, total diet replacement for weight control and food for special medical purposes (FSMP), and with the bioavailability of calcium from this source. The structural formula of the proposed complex is based on expert judgement and not supported by any analytical data. On the basis of the available data, the Panel concluded that there was insufficient scientific evidence of a difference between the proposed novel food ingredient named as diâcalcium malate (DCM) and calcium malate already authorised as a source of calcium included in Annex II to Directive 2002/46/EC. Accordingly, the Panel was unable to assess the safety of DCM as a novel food ingredient. On the basis of the results provided, the Panel considered that DCM does not completely dissociate into calcium and malic acid. The Panel concluded that when DCM dissociates, calcium would be available following ingestion of DCM and the bioavailability would appear similar to values reported for other sources of calcium already permitted. Furthermore, the Panel concluded that on the basis of the information available it was not possible to calculate the exposure to DCM as a source of calcium to foods for the general population, food supplements, total diet replacement for weight control and FSMP

Safety in use of glucosylated steviol glycosides as a food additive in different food categories
The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion on the safety of glucosylated steviol glycosides proposed for use as a new food additive in different food categories. According to the applicant, glucosylated steviol glycosides preparations consist of not less than 95% (on anhydrous basis) total steviol glycosides, made up of glucosylated steviol glycosides of different molecular weights as well as any remaining steviol glycosides. The applicant proposed that glucosylated steviol glycosides and parent steviol glycosides undergo a common metabolic process in pathway following ingestion and suggested that data from steviol glycosides can be used for readâacross to glucosylated steviol glycosides. The limited evidence provided in the application dossier did not demonstrate the complete hydrolysis of the glucosylated steviol glycosides. No toxicological studies on glucosylated steviol glycoside preparations under evaluation have been provided for its assessment. The Panel concluded that the submitted data are insufficient to assess the safety of the glucosylated steviol glycoside preparations to be used as a new food additive

Evaluation of four new studies on the potential toxicity of titanium dioxide used as a food additive (E 171)
The European Commission requested EFSA to carry out a scientific evaluation on four studies on the potential toxicity of titanium dioxide (TiO2) used as a food additive (E 171) and to indicate whether they would merit reâopening the existing opinion of EFSA on the safety of TiO2 (E 171) as a food additive. The results of the Bettini et al. (2017) study did not provide enough justification for a new carcinogenicity study, but, should additional useful mechanistic information become available, this could be reconsidered in future. The new in vitro findings in the Proquin et al. (2017) study did not modify the conclusion on the genotoxicity of TiO2 as stated in the previous EFSA opinion of 2016 on the safety of TiO2 (E 171) as a food additive. The effects of engineered TiO2 nanoparticles reported by the Guo et al. (2017) study were of uncertain biological significance and therefore of limited relevance for the risk assessment of the food additive TiO2 (E 171). There was significant uncertainty in the risk assessment performed by Heringa et al. (2016), which did not include a weight of evidence analysis of the whole database. The Panel considered that the four studies evaluated, highlighted some concerns but with uncertainties, therefore their relevance for the risk assessment was considered limited and further research would be needed to decrease the level of uncertainties. Overall, three of the studies, reporting that TiO2 induced various effects in in vitro and in vivo models, may be useful for hazard identification of TiO2. In the fourth study by Heringa et al. (2016), numerous assumptions were made, which resulted in large uncertainty in their conclusion. Altogether, the Panel concluded that the outcome of the four studies did not merit reâopening the existing opinion of EFSA related to the safety of TiO2 (E 171) as a food additive

Scientific opinion on the evaluation of authorised ferric sodium EDTA as an ingredient in the context of Regulation (EC) 258/97 on novel foods and Regulation (EU) 609/2013 on food intended for infants and young children, food for special medical purposes and total diet replacement for weight control
The present opinion deals with the evaluation of the proposed increase of the currently authorised maximum amounts of ferric sodium ethylenediaminetetraacetic acid (EDTA) as a novel food ingredient used as a source of iron, and its extension of use in processed cerealâbased foods and baby foods. The applicant also provided information on two forms of ferric sodium EDTA, one previously assessed by EFSA and a new one of finer consistency. To support the proposed changes to the uses of ferric sodium EDTA, the applicant proposed a revision of the current acceptable daily intake (ADI) for EDTA, derived from that set for the food additive calcium disodium EDTA (E 385). The Panel confirmed that ferric sodium EDTA is a source from which iron is bioavailable. In assessing the safety of the proposed revision to the existing specifications for the novel food ingredient ferric sodium EDTA, the Panel noted that this would not discriminate between the previously evaluated substance and the one of finer consistency. In particular, the Panel noted that particle size was not one of the proposed parameters for the revised specifications. The Panel noted that it was not possible to determine whether particles of ferric sodium EDTA in the nano range were present in the product with finer consistency in the solid form. The toxicological data submitted did not add any new relevant information to the database on which the current ADI for EDTA is based. Consequently, the Panel concluded that there was no sound scientific justification to increase the ADI for EDTA and hence increase the use levels of ferric sodium EDTA or introduce additional uses as proposed by the applicant. The Panel recommended that additional toxicological data should be provided to address the shortcomings in the available toxicity database prior to the reâevaluation of calcium disodium EDTA (E 385)

Refined exposure assessment of extracts of rosemary (E 392) from its use as food additive
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 0â0.3 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 (3â9 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)

Reâevaluation of sodium, potassium and calcium salts of fatty acids (E 470a) and magnesium salts of fatty acids (E 470b) as food additives
The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion reâevaluating the safety of sodium, potassium and calcium salts of fatty acids (E 470a) and magnesium salts of fatty acids (E 470b) when used as food additives. In 1991, the Scientific Committee on Food (SCF) established a group acceptable daily intake (ADI) ânot specifiedâ for the fatty acids (myristicâ, stearicâ, palmiticâ and oleic acid) and their salts. The sodium, potassium, calcium and magnesium salts of fatty acids are expected to dissociate in the gastrointestinal tract to fatty acid carboxylates and their corresponding cations. There were no data on subchronic toxicity, chronic toxicity, reproductive and developmental toxicity of the salts of fatty acids. There was no concern for mutagenicity of calcium caprylate, potassium oleate and magnesium stearate. From a carcinogenicity study with sodium oleate, a no observed adverse effect level (NOAEL) could not be identified but the substance was considered not to present a carcinogenic potential. Palmiticâ and stearic acid which are the main fatty acids in E 470a and E 470b were already considered of no safety concern in the reâevaluation of the food additive E 570. The fatty acid moieties of E 470a and E 470b contributed maximally for 5% to the overall intake of saturated fatty acids from all dietary sources. Overall, the Panel concluded that there was no need for a numerical ADI and that the food additives sodium, potassium, calcium and magnesium salts of fatty acids (E 470a and E 470b) were of no safety concern at the reported uses and use levels

Reâevaluation of propaneâ1,2âdiol (E 1520) as a food additive
The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion reâevaluating the safety of propaneâ1,2âdiol (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 propaneâ1,2âdiol. Propaneâ1,2âdiol 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 propaneâ1,2âdiol is excreted in the urine. No treatmentârelated 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 2âyear study in dogs. No adverse effects were reported in a 2âyear chronic study in rats with propaneâ1,2âdiol (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. Propaneâ1,2âdiol (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 brandâloyal refined exposure scenario did not exceed the ADI in any of the population groups from the use of propaneâ1,2âdiol (E 1520) at the reported use levels and analytical results

Guidance on safety evaluation of sources of nutrients and bioavailability of nutrient from the sources (Revision 1)
This guidance describes the scientific data required to allow an evaluation of the safety of new substances that are proposed for use as sources of nutrients in food supplements, foods for the general population or foods for specific groups and an assessment 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 was adopted by the Panel on Food Additives and Nutrient Sources added to Food (ANS Panel) on 16 May 2018. Upon request from EFSA, the present guidance has been revised to inform applicants of new provisions set out in Regulation (EC) No 178/2002, as amended by Regulation (EU) 2019/1381 on the transparency and sustainability of the EU risk assessment in the food chain

Safety of orthosilicic acidâvanillin complex (OSAâVC) as a novel food ingredient to be used in food supplements as a source of silicon and bioavailability of silicon from the source
The present scientific opinion deals with the safety of orthosilicic acid-vanillin complex (OSA-VC) as a novel food ingredient for use as a source of silicon (Si) in food supplements and with the bioavailability of Si from this source. OSA-VC is stable in liquid solution at low pH values. OSA from OSA-VC was available as revealed by the increase in plasma Si concentrations after oral ingestion in human volunteers. The toxicological data provided in support of the current application were not in accordance with the Tier 1 requirement of the âGuidance for submission for food additive evaluationsâ; however, this was considered justified by the Panel given that OSA-VC at pH 6.8 dissociates into orthosilicic acid and vanillin. The daily consumption of OSA-VC at the dose recommended by the applicant would provide a supplemental intake of Si of approximately 10â18 mg Si/day which would result in an estimated total intake of roughly 30â70 mg Si/day. The maximum vanillin intake resulting from the consumption of OSA-VC would be less than 5% of the acceptable daily intake (ADI) value for vanillin of 10 mg/kg body weight (bw) per day established by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) in 2002. The Panel concluded that there would be no safety concern with the proposed use and use level of OSA-VC as a novel food ingredient intended to be used as a source of Si in food supplements for the adult population. The Panel concluded that OSA, measured as Si, is bioavailable following ingestion of OSA-VC and appears similar to values reported in the literature for other established sources of OSA
