Safety evaluation of the food enzyme glucose isomerase from Streptomyces murinus (strain NZYM-GA).

The food enzyme is a glucose isomerase (d-xylose aldose-ketose-isomerase; EC 5.3.1.5) produced with a non-genetically modified Streptomyces murinus strain NZYM-GA by Novozymes A/S. The glucose isomerase is intended only to be used in an immobilised form in glucose isomerisation for the production of high fructose syrups. Residual amounts of total organic solids are removed by the purification steps applied during the production of high fructose syrups using the immobilised enzyme; consequently, dietary exposure was not calculated. Genotoxicity tests did not raise a safety concern. Similarity of the amino acid sequence to those of known allergens was searched and no match was found. The Panel considered that, under the intended conditions of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood to occur is considered to be low. Based on the data provided, the immobilisation process and the removal of total organic solids during the production of high fructose syrups, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

Safety evaluation of the food enzyme lysophospholipase from Trichoderma reesei (strain RF7206).

The food enzyme lysophospholipase (EC 3.1.1.5) is produced with the genetically modified Trichoderma reesei strain RF7206 by AB Enzymes GmbH. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism and recombinant DNA. The lysophospholipase food enzyme is intended to be used in starch processing for the production of glucose syrups. Residual amounts of total organic solids (TOS) are removed by the purification steps applied during the production of glucose syrups, consequently, dietary exposure was not calculated. Genotoxicity tests did not raise a safety concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level at the highest dose tested of 927 mg TOS/kg body weight (bw) per day. Similarity of the amino acid sequence to those of known allergens was searched and no match was found. The Panel considered that, under the intended condition of use, the risk of allergic sensitisation and elicitation reactions upon dietary exposure to this food enzyme cannot be excluded, but the likelihood of such reactions to occur is considered to be low. Based on the data provided and the removal of TOS during the intended food production process, the Panel concluded that this food enzyme does not raise safety concerns under the intended conditions of use.

Safety evaluation of the food enzyme α-amylase from a genetically modified strain of Bacillus licheniformis (DP-Dzb54).

The food enzyme α-amylase (4-α-d-glucan glucanohydrolase; EC 3.2.1.1) is produced with the genetically modified Bacillus licheniformis strain DP-Dzb54 by Danisco. The α-amylase is intended to be used in starch processing for the production of glucose syrups. Residual amounts of total organic solids are removed by the purification steps applied during the production of glucose syrups; consequently, dietary exposure was not calculated. The parental strain meets all the requirements for the Qualified Presumption of Safety approach for risk assessment, except the absence of acquired antimicrobial resistance genes. However, this has no practical consequence for the food enzyme as it has been shown not to contain viable cells and DNA from the production strain. As no other concerns arising from the microbial source and its subsequent genetic modification or from the manufacturing process have been identified, the Panel considers that toxicological tests are not needed for the assessment of this food enzyme. Similarity of the amino acid sequence to those of known allergens was searched and no match was found. The Panel considered that, under the intended conditions of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood to occur is considered to be low. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

Safety evaluation of the food enzyme endo-1,4-ß-xylanase from Bacillus subtilis (strain XAS).

The food enzyme is an endo-1,4-ß-xylanase (4-ß-d-xylan xylanohydrolase; EC 3.2.1.8) produced with the genetically modified Bacillus subtilis strain XAS. Antibiotic resistance genes are present in the production organism on a self-replicative vector. The endo-1,4-ß-xylanase is intended to be used in baking processes. Based on the maximum use levels, dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.014 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not raise a safety concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no-observed-adverse-effect level (NOAEL) of 55 mg TOS/kg bw per day that, compared with the estimated dietary exposure, results in a sufficiently high margin of exposure (MOE) (of at least 3,600). Similarity of the amino acid sequence to those of known allergens was searched and no match was found. The Panel considered that, under the intended conditions of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood to occur is considered to be low. Since the absence of viable cells in the food enzyme has not been adequately demonstrated, the Panel cannot conclude on the risks associated with the possible spread of a genetically modified bacterial strain carrying antimicrobial resistance determinants.

Safety assessment of the substance poly((R)-3-hydroxybutyrate-co-(R)-3-hydroxyhexanoate) for use in food contact materials.

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of poly((R)-3-hydroxybutyrate-co-(R)-3-hydroxyhexanoate) (PHBH), CAS No 147398-31-0 and food contact material (FCM) substance No 1059. This biodegradable copolymer is produced by fermentation of palm oil using a genetically modified microorganism (Cupriavidus necator). Overall migration was up to 5.4 mg/kg. Oligomers are hydroxyl-terminated or with crotyl- and hexenyl end-groups from dehydration of hydroxyl end-groups. In the absence of calibration standards, the total oligomer migration was set at the overall migration values. Other degradation products are crotonic acid and (E)-2-hexenoic acid. Crotonic acid is authorised for use in FCMs with a specific migration limit (SML) of 0.05 mg/kg food. For (E)-2-hexenoic acid, no indication for genotoxicity was identified by the EFSA CEF Panel in its group evaluation of flavouring substances in FGE.05Rev2 (EFSA CEF Panel, 2010b). The other migrating substances detected, ■■■■■, are from the authorised substance 'palm oil and/or palm fatty acid distillate' (FCM substance No 9) used as a carbon source for the fermentation and do not give rise to safety concern. A PHBH oligomer mixture was synthesized to simulate that migrating. It did not give rise to concern for genotoxicity. From the repeated dose 90-day oral toxicity study in rats, the Panel identified the no-observed-adverse-effect level (NOAEL) at the highest dose tested in males, 1,364 mg/kg body weight (bw) per day. The Panel concluded that the potential for bioaccumulation of oligomers is low. Overall, the CEP Panel concluded that the substance PHBH is not of safety concern for the consumer if it is used alone or blended with other polymers in contact with all kinds of food during more than 6 months at room temperature or below, including hot-fill or a short heating up phase. The specific migration of all oligomers < 1,000 Da should not exceed 5 mg/kg food. The migration of crotonic acid should not exceed the SML of 0.05 mg/kg food. As the migration of (E)-2-hexenoic acid can be expected to be always lower than that of crotonic acid, no individual restriction is necessary.

Safety assessment of the substance, montmorillonite clay modified with hexadecyltrimethylammonium bromide, for use in food contact materials.

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of montmorillonite clay modified with hexadecyltrimethylammonium bromide (HDTA) when used as an additive at up to ■■■■■ in polylactic acid (PLA) bottles intended for contact with water for long-term storage at ambient temperature or below. The modified clay, which 90% w/w of the particles have a dimension of 33.1 µm or less and the average size is 9 µm, has a layered structure with layers of a thickness below 100 nm. When incorporated in PLA, nanosized layers can be dispersed in the matrix, but are not expected to migrate. Thermal degradation is not expected at the maximum manufacturing temperature. No loss of integrity of the PLA surface due to interaction with bottled water was observed. The overall migration was very low. No migration of HDTA was detected at the limit of detection ■■■■■. Migration of aluminium was below or at the limit of detection ■■■■■, which would conservatively correspond to approximately ■■■■■. Comparative analysis of bottled water with and without the modified clay did not reveal additional peaks corresponding to impurities identified in the modifier and/or in the modified clay. Moreover, ■■■■■, and the modifier HDTA have been evaluated and authorised. Therefore, the CEP Panel concluded that the substance montmorillonite clay modified with HDTA bromide is not of safety concern for the consumer if the substance is used as an additive at up to ■■■■■ in PLA plastic bottles and other containers intended for long-term storage of water at ambient temperature or below, as requested by the applicant.

Safety evaluation of the food enzyme alpha-amylase from a genetically modified Trichoderma reesei (strain DP-Nzb48).

The food enzyme alpha-amylase (4-α-d-glucan glucanohydrolase; EC 3.2.1.1) is produced with a genetically modified strain of Trichoderma reesei by Danisco US Inc. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism and recombinant DNA. This α-amylase is intended to be used in distilled alcohol production and brewing processes. Residual amounts of total organic solids (TOS) are removed by distillation; consequently, dietary exposure was not calculated for this use. Based on the maximum use levels recommended for the brewing processes and individual data from the EFSA Comprehensive European Food Consumption Database, dietary exposure to the food enzyme-TOS was estimated to be up to 1.701 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests with the food enzyme did not indicate a genotoxic concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no-observed-adverse-effect level (NOAEL) at the highest dose of 230 mg TOS/kg bw per day. Similarity of the amino acid sequence to those of known allergens was searched and one match was found. The Panel considered that, under the intended condition of use, the risk of allergic sensitisation and elicitation reactions upon dietary exposure to this food enzyme cannot be excluded, but the likelihood is considered low. Based on the removal of residues of the food enzyme during distillation, the Panel concluded that the use of this enzyme in the distilled alcohol production is safe. When used in brewing processes, the margin of exposure calculated from the data provided is only (at least) 135, but no safety issues were identified.

Safety evaluation of the food enzyme pullulanase from a genetically modified Bacillus licheniformis (strain DP-Dzp39).

The food enzyme pullulanase (pullulan 6-α-glucanohydrolase; EC 3.2.1.41) is produced with a genetically modified Bacillus licheniformis (strain DP-Dzp39) by Danisco US Inc. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism and its recombinant DNA. This pullulanase is intended to be used in brewing processes, starch processing for glucose syrups production and distilled alcohol production. Residual amounts of total organic solids (TOS) are removed by distillation and by the purification steps applied during the production of glucose syrups, consequently, dietary exposure was not calculated for these food processes. For brewery products, based on the maximum use level recommended for the brewing processes and individual data from the EFSA Comprehensive European Food Consumption Database, dietary exposure to the food enzyme-TOS was estimated to be up to 0.053 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests with the food enzyme did not raise concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no-observed-adverse-effect level at the highest dose of 500 mg TOS/kg bw per day that, compared to the estimated dietary exposure, results in sufficiently high margin of exposure (at least 9,400). The amino acid sequence of the food enzyme did not match those of known allergens. The Panel considered that, under the intended condition of use, the risk of allergic sensitisation and elicitation reactions upon dietary exposure to this food enzyme cannot be excluded, but the likelihood is considered low. Based on the data provided, the Panel concluded that this food enzyme does not raise safety concerns under the intended conditions of use.

Safety assessment of the process Sharpak Bridgewater, based on Starlinger Decon technology, used to recycle post-consumer PET into food contact materials.

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Sharpak Bridgewater (EU register number RECYC166). The input is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, mainly bottles, with no more than 5% PET from non-food consumer applications. The 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 to control the performance of these critical steps are temperature, pressure, residence time and gas flow. It was demonstrated that this recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below the conservatively modelled migration of 0.1 µg/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process when used at up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill, is not considered of safety concern. Trays made of this recycled PET are not intended to be used, in microwave and conventional ovens and such use is not covered by this evaluation.

Safety assessment of the substance trimellitic acid, tris (2-ethylhexyl) ester, for use in food contact materials.

This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes and Processing aids (CEP Panel) is on the safety assessment of trimellitic acid, tris(2-ethylhexyl) ester, intended to be used as a plasticiser in the manufacture of soft poly(vinyl chloride) (PVC) materials and articles, such as wrap films (single uses) and tubing (repeated uses) at up to approximately 10% and 40%, respectively. Under the tested conditions, the substance migrated up to 165 µg/kg food from wrap films and was not detected in food simulant in contact with tubing. Based on the three reported in vitro genotoxicity studies, the Panel concluded that the substance does not raise concern for genotoxicity. The lowest no observed adverse effect level (NOAEL), derived from a 90-day oral toxicity study, was 225 mg/kg body weight (bw) per day. Based on data on toxicokinetic and metabolism, the substance does not give rise to concern for accumulation in humans. The substance does not cause developmental effects as induced by phthalic acid, bis(2-ethylhexyl) ester (DEHP). Assuming that impurities migrate pro-rata to a migration of the substance up to 5 mg/kg food, their estimated migration does not raise a safety concern. The Panel concluded that the substance does not raise safety concern for the consumer when used in the manufacture of soft PVC under the conditions requested by the applicant for (i) single use wrap films in contact with food for which simulants A, B and D1 are assigned, as well as (ii) tubing for repeated contacts with food for which simulants A and B are assigned. Overall, the use of the substance does not raise a safety concern if its migration does not exceed 5 mg/kg food. Due to the additional contribution from other sources of exposures, the application of an allocation factor should be considered.

Safety assessment of the process 'Jász-Plasztik', based on Vacurema Prime technology, used to recycle post-consumer PET into food contact materials.

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of the recycling process Jász-Plasztik (EU register number RECYC0157). The input are hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers and containing no more than 5% PET from non-food applications. They are heated in a batch reactor under vacuum and then heated in a continuous reactor under vacuum before being extruded into pellets. Having examined the results of the challenge test provided, the Panel concluded that the decontamination in the batch reactors (step 2) and in the continuous reactor (step 3) are the critical steps that determine the decontamination efficiency of the process. The operating parameters to control the performance of these critical steps are temperature, pressure and residence time. It was demonstrated that this recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below the conservatively modelled migration of 0.1 µg/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process when 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, with or without hotfill, is not considered of safety concern. Trays made of this recycled PET are not intended to be used in microwave and conventional ovens and such use is not covered by this evaluation.

Safety evaluation of the food enzyme 4-α-glucanotransferase from Aeribacillus pallidus (strain AE-SAS).

The food enzyme 4-α-glucanotransferase (1,4-α-d-glucan:1,4-α-d-glucan 4-α-d-glycosyltransferase, EC 2.4.1.25) is produced with a non-genetically modified Aeribacillus pallidus (previously identified as Geobacillus pallidus) strain from Amano Enzyme Inc. The food enzyme is intended to be used in baking processes and in starch processing for the production of modified dextrins. For baking processes, based on the maximum use levels recommended and individual data from the EFSA Comprehensive European Food Database, dietary exposure to the food enzyme-Total Organic Solids (TOS) was estimated to be up to 0.050 mg TOS/kg body weight (bw) per day. Exposure assessment for the modified dextrins was not considered necessary. Genotoxicity tests did not raise a safety concern. Systemic toxicity was assessed by a repeated dose 90-day oral toxicity study in rats. From this study, the Panel identified a no observed adverse effect level (NOAEL) of at least 900 mg TOS/kg bw per day, the highest dose tested. When the NOAEL value is compared to the estimated dietary exposure to the food enzyme used in baking, this results in a Margin of Exposure (MOE) of at least 18,000. The Panel considers that any additional exposure to the food enzyme from the use of modified dextrins will be covered by the above MOE. A search was made for similarity of the amino acid sequence of the food enzyme with those of known allergens. One match was found with a known respiratory allergen, an α-amylase. The Panel considered that an allergic reaction upon oral ingestion of 4-α-glucanotransferase produced by A. pallidus AE-SAS in individuals respiratory sensitised to α-amylase cannot be excluded, but the likelihood is considered to be low. Overall, the Panel concluded that, under the intended conditions of use and based on the data provided, this food enzyme does not give rise to safety concerns.

Safety evaluation of the food enzyme glucose oxidase from Aspergillus niger (strain ZGL).

The food enzyme glucose oxidase (ß-d-glucose:oxygen 1-oxidoreductase; EC 1.1.3.4) is produced with a genetically modified Aspergillus niger strain ZGL by DSM Food Specialties B.V.. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism and recombinant DNA. The glucose oxidase is intended to be used in baking processes. Based on the maximum use levels, dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.004 mg TOS/kg body weight (bw) per day. The toxicity studies were carried out with an asparaginase from A. niger (strain ASP). The Panel considered this enzyme as a suitable substitute to be used in the toxicological studies, because they derive from the same recipient strain, the location of the inserts are comparable, no partial inserts were present and the production methods are essentially the same. Genotoxicity tests did not raise a safety concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level (NOAEL) at the highest dose of 1,038 and 1,194 mg TOS/kg bw per day (for males and females, respectively) that, compared with the estimated dietary exposure, results in a sufficiently high margin of exposure (MoE) (of at least 260,000). Similarity of the amino acid sequence to those of known allergens was searched and one match was found. The Panel considered that, under the intended conditions of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood to occur is considered to be low. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

Safety evaluation of the food enzyme triacylglycerol lipase from Aspergillus niger (strain LFS).

The food enzyme triacylglycerol lipase (triacylglycerol acylhydrolase, EC 3.1.1.3) is produced with a genetically modified Aspergillus niger strain LFS by DSM Food Specialties B.V.. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism and recombinant DNA. The triacylglycerol lipase food enzyme is intended to be used in baking processes. Based on the maximum use levels, dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.020 mg TOS/kg body weight (bw) per day. The toxicity studies were carried out with an asparaginase from A. niger (strain ASP). The Panel considered this enzyme as a suitable substitute to be used in the toxicological studies, because they derive from the same recipient strain, the location of the inserts are comparable, no partial inserts were present and the production methods are essentially the same. Genotoxicity tests did not raise a safety concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level (NOAEL) at the highest dose of 1,038 and 1,194 mg TOS/kg bw per day (for males and females, respectively) that, compared with the estimated dietary exposure, results in a sufficiently high margin of exposure (MoE) (of at least 51,900). Similarity of the amino acid sequence to those of known allergens was searched and no match was found. The Panel considered that, under the intended conditions of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood to occur is considered to be low. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

Safety evaluation of the food enzyme ß-glucanase, xylanase and cellulase from Mycothermus thermophiloides (strain NZYM-ST).

The food enzyme has three declared activities (endo-1,3(4)-ß-glucanase EC 3.2.1.6, endo-1,4-ß-xylanase EC 3.2.1.8 and cellulase (endo-1,4-ß-d-glucanase EC 3.2.1.4)) and is produced with a non-genetically modified Mycothermus thermophiloides strain by Novozymes A/S. It is intended to be used in baking and brewing processes. For the two intended uses, based on the maximum use levels recommended and individual data from the EFSA Comprehensive European Food Database, dietary exposure to the food enzyme-Total Organic Solids (TOS) was estimated to be up to 0.411 mg TOS/kg body weight (bw) per day. Genotoxicity tests did not raise a safety concern. Systemic toxicity was assessed by a repeated dose 90-day oral toxicity study in rats. From this study, the Panel identified a no observed adverse effect level (NOAEL) of at least 620 mg TOS/kg bw per day, the highest dose tested. When the NOAEL is compared to the estimated dietary exposure, this results in a margin of exposure of at least 1,500. A search was made for similarity of the amino acid sequence of the declared activities with those of known allergens. Four matches were found with endo-1,3(4)-ß-glucanase to known respiratory allergens, two from dust mites and two Aspergillus fumigatus allergens. The Panel considered that an allergic reaction upon oral ingestion of enzymes produced by M. thermophiloides strain NZYM-ST in individuals respiratory sensitised to these allergens cannot be excluded, but the likelihood is considered to be low. Overall, the Panel concluded that, under the intended conditions of use and based on the data provided, this food enzyme does not give rise to safety concerns.

Safety evaluation of the food enzyme phospholipase C from a genetically modified Komagataella phaffii (strain PRF).

The food enzyme phospholipase C (EC 3.1.4.3) is produced with a genetically modified Komagataella phaffii (formerly Pichia pastoris) (strain PRF) by DSM. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism and recombinant DNA. This phospholipase C is intended to be used in fats and oils processing for degumming. The residual amounts of total organic solids (TOS) are removed during refinement steps applied during fats and oils processing. Consequently, no dietary exposure was calculated. Genotoxicity tests did not indicate a safety concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level (NOAEL) of at least 1,672 mg TOS/kg body weight per day, the highest dose tested. Similarity of the amino acid sequence to those of known allergens was searched and no match was found. The Panel considered that, under the intended conditions of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood is considered to be low. Based on the data provided and the removal of TOS during the fats and oils processing for degumming, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

Safety evaluation of the food enzyme endo-1,4-ß-xylanase from a genetically modified Bacillus licheniformis (strain NZYM-CE).

The food enzyme endo-1,4-ß-xylanase (4-ß-d-xylan xylanohydrolase; EC 3.2.1.8) is produced with a genetically modified Bacillus licheniformis (strain NZYM-CE) by Novozymes A/S. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism and recombinant DNA. This xylanase is intended to be used in baking and cereal-based processes. Based on the maximum use levels recommended for the respective food processes and individual data from the EFSA Comprehensive European Food Consumption Database, dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.012 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not indicate a genotoxic concern. The systemic toxicity was assessed by a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level (NOAEL) of at least 1,020 mg TOS/kg bw per day, the highest dose tested. When the NOAEL value is compared to the estimated dietary exposure, this results in a margin of exposure (MoE) of at least 85,000. Similarity of the amino acid sequence to those of known allergens was searched and no match was found. The Panel considered that, under the intended conditions of use, the risk of allergic sensitisation and elicitation reactions upon dietary exposure to this food enzyme cannot be excluded, but the likelihood is considered to be low. Overall, the Panel concluded that based on the data provided and the derived MoE, this food enzyme does not give rise to safety concerns under the intended conditions of use.

Safety assessment of the process Alimpet, based on EREMA MPR B2B technology, used to recycle post-consumer PET into food contact materials.

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of the Alimpet recycling process (EU register number RECYC159), which is based on the EREMA Multi-Purpose Reactor (MPR) technology. The input is 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. They are treated in a continuous reactor under vacuum and high temperature. Having examined the results of the challenge test provided, the Panel concluded that the continuous reactor is the critical step that determines the decontamination efficiency of the process. The operating parameters controlling its performance 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 0.1 µg/kg food, derived from the exposure scenario for infants. Therefore, the Panel concluded that recycled PET obtained from the process is not of safety concern when used to manufacture articles intended for food contact applications if it is produced in compliance with the conditions specified in the conclusion of this opinion. Articles made of this recycled PET are not intended to be used in microwave and conventional ovens and such use is not covered by this evaluation.

Safety assessment of the process Texplast, based on EREMA Advanced technology, used to recycle post-consumer PET into food contact materials.

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of the Texplast recycling process (EU register number RECYC158), which is based on the EREMA Advanced technology. The input is 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. They are heated in a continuous reactor under vacuum. Having examined the results of the challenge test provided, the Panel concluded that this continuous reactor step (step 3) is the critical step that determines the decontamination efficiency of the process. The operating parameters controlling its performance 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 0.1 µg/kg food, derived from the exposure scenario for infants. Therefore, the Panel concluded that recycled PET obtained from the process is not of safety concern when used to manufacture articles intended for food contact applications if it is produced in compliance with the conditions specified in the conclusion of this opinion. Articles made of this recycled PET are not intended to be used in microwave and conventional ovens and such use is not covered by this evaluation.

Safety assessment of the substance phosphorous acid, triphenyl ester, polymer with alpha-hydro-omega-hydroxypoly[oxy(methyl-1,2-ethanediyl)], C10-16 alkyl esters, for use in food contact materials.

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of the substance 'phosphorous acid, triphenyl ester, polymer with alpha-hydro-omega-hydroxypoly[oxy(methyl-1,2-ethanediyl)], C10-16 alkyl esters', obtained by reaction of ■■■■■, when used as an additive at up to 0.2% w/w in high impact polystyrene. The plastic, in the form of films and articles, is intended for contact with aqueous, acidic, low-alcohol and fatty foods for long-term storage at room temperature and below, after hot-fill and/or heating up to 100°C for up to 2 h. Based on genotoxicity tests with negative results, the Panel considered that there is no evidence of mutagenicity and chromosomal damage of the substance and its phosphate form. From a repeated dose 90-day oral toxicity study in rats, the Panel identified the no-observed-adverse-effect level as 50 mg/kg body weight (bw) per day. No effects of induced delayed neurotoxicity in hens were observed. Migration from high impact polystyrene containing the substance at 0.2%, measured through the phosphorous content of the substance, reached 0.001 mg/kg in 10% ethanol and 0.1 mg/kg in 95% ethanol. Migration into acidic food/simulant is expected to be below 0.001 mg/kg. Regarding the oligomers and other reaction/degradation products detected, the phosphorous-containing substances were adequately represented in the toxicity experiments conducted. Those not containing phosphorous were hydrolysis products either listed in Regulation (EU) 10/2011 and their estimated worst-case migrations were well below their respective specific migration limits (SMLs) or no alerts for genotoxicity were noted. Overall, the CEP Panel concluded that the substance 'phosphorous acid, triphenyl ester, polymer with alpha-hydro-omega-hydroxypoly[oxy(methyl-1,2-ethanediyl)], C10-16 alkyl esters' does not raise a safety concern for the consumer if it is used at up to 0.2% w/w in high impact polystyrene materials and articles and its migration does not exceed 0.05 mg/kg food.
