Scientific Opinion of Flavouring Group Evaluation 407 (FGE.407): 4-amino-5-(3-(isopropylamino)-2,2-dimethyl-3-oxopropoxy)-2-methylquinoline-3-carboxylic acid

The EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF) was requested to deliver a scientific opinion on the implications for human health of the flavouring substance 4-amino-5-(3-(isopropylamino)-2,2-dimethyl-3-oxopropoxy)-2-methylquinoline-3-carboxylic acid [FL-no: 16.130], in the Flavouring Group Evaluation 407 (FGE.407), according to Regulation (EC) No 1331/2008 of the European Parliament and of the Council. The substance has not been reported to occur in natural source materials of botanical or animal origin. It is intended to be used as both the parent compound and its hemisulfate monohydrate salt as a flavouring substance with modifying properties in specific categories of food. The chronic dietary exposure to the substance estimated using the added portions exposure technique (APET), is calculated to be 882 μg/person per day for a 60-kg adult and 547 μg/person per day for a 15-kg 3-year-old child. There is no concern with respect to genotoxicity. A 90-day dietary administration study in rats showed no adverse effects for doses up to 100 mg/kg body weight (bw) per day, providing an adequate margin of safety. Developmental toxicity was not observed in a study with rats at the dose levels up to 1,000 mg/kg bw per day. The Panel concluded that [FL-no: 16.130] and its hemisulfate monohydrate salt are not expected to be of safety concern at the estimated levels of dietary exposure calculated using the APET approach. This conclusion applies only to the use of the substance as a flavour modifier as requested and when used at the levels as specified for foods from different food categories.
