Scientific opinion on flavouring group evaluation 77, revision 3 (FGE.77Rev3): consideration of pyridine, pyrrole and quinoline derivatives evaluated by JECFA (63rd meeting) structurally related to pyridine, pyrrole, indole and quinoline derivatives evaluated by EFSA in FGE.24Rev2

Abstract The Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids of the EFSA was requested to consider evaluations of flavouring substances assessed since 2000 by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and to decide whether further evaluation is necessary, as laid down in Commission Regulation (EC) No 1565/2000. The present consideration concerns a group of 22 pyridine, pyrrole and quinoline derivatives evaluated by JECFA (63rd meeting). The revision of this consideration is made since additional genotoxicity data have become available for 6‐methylquinoline [FL‐no: 14.042]. The genotoxicity data available rule out the concern with respect to genotoxicity and accordingly the substance is evaluated through the Procedure. For all 22 substances [FL‐no: 13.134, 14.001, 14.004, 14.007, 14.030, 14.038, 14.039, 14.041, 14.042, 14.045, 14.046, 14.047, 14.058, 14.059, 14.060, 14.061, 14.065, 14.066, 14.068, 14.071, 14.072 and 14.164] considered in this Flavouring Group Evaluation (FGE), the Panel agrees with the JECFA conclusion, ‘No safety concern at estimated levels of intake as flavouring substances’ based on the Maximised Survey‐derived Daily Intake (MSDI) approach. Besides the safety assessment of these flavouring substances, the specifications for the materials of commerce have also been evaluated, and the information is considered adequate for all the substances. For the following substances [FL‐no: 13.134, 14.001, 14.030, 14.041, 14.042, 14.058, 14.072], the Industry has submitted use levels for normal and maximum use. For the remaining 15 substances, use levels are needed to calculate the modified Theoretical Added Maximum Daily Intakes (mTAMDIs) in order to identify those flavouring substances that need more refined exposure assessment and to finalise the evaluation.

Safety assessment of the process ‘Veroniki Ecogrup SRL’, based on Starlinger Decon technology, used to recycle post-consumer PET into food contact materials

Abstract This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety evaluation of the recycling process Veroniki Ecogrup SRL (EU register No RECYC0145), which is based on the Starlinger Decon technology. The decontamination efficiency of the process was demonstrated by a challenge test. The input of this process is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post‐consumer PET containers, mainly bottles, containing no more than 5% of PET from non‐food consumer applications. In this technology, washed and dried PET flakes are preheated before being submitted to solid‐state polycondensation (SSP) in a continuous reactor at high temperature under vacuum and gas flow. Having examined the challenge test provided, the Panel concluded that the preheating (step 2) and the decontamination in the continuous SSP reactor (step 3) are the critical steps that determine the decontamination efficiency of the process. The operating parameters that control their performance are well defined and are temperature, pressure, residence time and gas flow for step 2 and 3. Under these conditions, it was demonstrated that the recycling process under evaluation, using the Starlinger Decon technology, is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.1 μg/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process and intended to be used up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long‐term storage at room temperature is not considered of safety concern. Trays made of this PET are not intended to be used, and should not to be used in microwave and conventional ovens.

Safety assessment of the process ‘Alimpet’, based on EREMA MPR technology, used to recycle post-consumer PET into food contact materials

Abstract This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety assessment of the recycling process Alimpet (EU register number RECYC0136), which is based on the EREMA Multi‐Purpose Reactor (MPR) technology. The input to this process is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post‐consumer PET containers, containing no more than 5% PET from non‐food consumer applications. In this technology, post‐consumer washed and dried PET flakes are heated in a continuous reactor under vacuum. Having examined the results of the challenge test provided, the Panel concluded that the continuous reactor step (step 2) is the critical step that determines the decontamination efficiency of the process. The operating parameters controlling its performance are well defined and are temperature, pressure and residence time. It was demonstrated that, depending on the operating conditions, the recycling process under evaluation is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.15 μg/kg food derived from the exposure scenario for toddlers. The Panel concluded that recycled PET obtained from the process is not of safety concern when used in extruded PET sheet for thermoforming trays and containers made with up to 100% recycled post‐consumer PET, and used for contact with all types of foodstuff except packaged water, for long‐term storage at room temperature. Thermoformed trays are not intended to be used and should not be used in microwave and conventional ovens.

Safety assessment of the process ‘Coexpan Deutschland’, based on EREMA Basic technology, used to recycle post‐consumer PET into food contact materials

Abstract This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety assessment of the Coexpan Deutschland recycling process (EU register number RECYC0140), which is based on the EREMA Basic technology. The input to this process is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post‐consumer PET containers, containing no more than 5% PET from non‐food consumer applications. In this technology, post‐consumer washed and dried PET flakes are heated in a continuous reactor under vacuum before being extruded. Having examined the results of the challenge test provided, the Panel concluded that the continuous reactor step (step 2) is the critical step that determines the decontamination efficiency of the process. The operating parameters controlling its performance are well defined and are temperature, pressure and residence time. It was demonstrated that, depending on the operating conditions, the recycling process under evaluation is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.15 μg/kg food, derived from the exposure scenario for toddlers. The Panel concluded that recycled PET obtained from the process is not of safety concern when the final thermoformed trays and containers manufactured with the recycled sheets and not used for packaging water contain up to 100% recycled post‐consumer PET. Thermoformed trays are not intended to be used and should not be used in microwave and conventional ovens.

Safety evaluation of the food enzyme β-amylase obtained from soybean (Glycine max) whey

Abstract The food enzyme considered in this opinion is a β‐amylase (EC 3.2.1.2) from soybean submitted by Nagase (Europa) GmbH. This β‐amylase is intended to be used in the starch processing for maltose syrup production and the manufacture of a Japanese rice cake type. Based on the maximum use levels recommended for the respective food processes, dietary exposure to the food enzyme–total organic solids (TOS) was estimated on the basis of Japanese consumption data. Conservative average infant formula consumption, as reported in the EFSA Draft Guidance on risk assessment of substances present in food intended for infants below 16 weeks of age, was used to estimate the exposure to a fraction of soybean comparable to the food enzyme–TOS, resulting from the consumption of soybean‐derived foods. The exposure estimate to the food enzyme–TOS was found to be lower than the comparable fraction from the source material. Potential allergenicity of the β‐amylase was evaluated by searching for similarity of the amino acid sequence to those of known allergens, and no match was found. The β‐amylase is produced from soybean, which is a known allergenic food. Japanese rice cake, consequently, may contain traces of soybean allergens, which may give rise to safety concerns in soybean‐allergic consumers. Based on the origin of the food enzyme from edible parts of soybean, the manufacturing process, the compositional and biochemical data provided and the dietary intake estimates, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use, except that Japanese rice cake produced with this food enzyme may contain traces of soybean allergens.

Safety evaluation of the food enzyme pullulanase from genetically modified Bacillus subtilis strain NZYM‐AK

Abstract The food enzyme considered in this opinion is a pullulanase (pullulan 6‐α‐glucanohydrolase; EC 3.2.1.41), produced with the genetically modified Bacillus subtilis strain NZYM‐AK by Novozymes A/S (Denmark). The pullulanase food enzyme is intended to be used in starch processing for the production of glucose syrups. Since the residual amounts of total organic solids (TOS) in glucose syrups after filtration and purification during starch processing were considered negligible, no dietary exposure was calculated. Genotoxicity tests made with the food enzyme indicated no genotoxic concern. A repeated dose 90‐day oral toxicity study in rodents, carried out with a pullulanase produced with a predecessor strain, showed no concern with respect to systemic toxicity. The allergenicity was evaluated by searching for similarity of the amino acid sequence to those of known allergens; no match was found. The Panel considers that there are no indications for allergic reactions. Based on the microbial source, genetic modifications performed, the manufacturing process, the compositional and biochemical data provided, the findings in the toxicological studies and allergenicity assessment, the Panel concludes that this food enzyme does not give rise to safety concerns under the intended conditions of use.

Safety evaluation of the food enzyme pullulanase from Pullulanibacillus naganoensis strain AE-PL

Abstract The food enzyme considered in this opinion is a pullulanase (pullulan 6‐α‐glucanohydrolase; EC 3.2.1.41) produced with a non‐genetically modified Pullulanibacillus naganoensis (strain AE‐PL) by Amano Enzyme Inc. (Japan). The pullulanase food enzyme is intended to be used in starch processing for the production of glucose syrups. Since residual amounts of total organic solid (TOS) in glucose syrups are removed by filtration and purification during starch processing, dietary exposure assessment was not performed. Genotoxicity tests made with the food enzyme indicated no genotoxic potential. A repeated dose 90‐day oral toxicity study in rodents, carried out with the food enzyme, showed minor effects that were considered to be of no biological relevance. The allergenicity was evaluated by comparing the amino acid sequence to those of known allergens and no match was found. The Panel considered that there are no indications for food allergic reactions to dietary intake of this food enzyme. Based on the removal of residual amounts of TOS from glucose syrups, consumer exposure is not expected. In addition, the safety of the manufacturing process, the compositional and biochemical data lead the Panel to conclude that the food enzyme pullulanase from P. naganoensis (strain AE‐PL) does not give rise to safety concerns under the intended conditions of use.
