Safety evaluation of the food enzyme triacylglycerol lipase from the non-genetically modified Penicillium caseifulvum strain AE-LRF

Abstract

The food enzyme triacylglycerol lipase (triacylglycerol acylhydrolase; EC 3.1.1.3) is produced with the non-genetically modified Penicillium caseifulvum strain AE-LRF by Amano Enzyme Inc. The food enzyme was free from viable cells of the production organism. It is intended to be used in four food manufacturing processes. Dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.013 mg TOS/kg body weight (bw) per day in European populations. 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 of 69 mg TOS/kg bw per day, the highest dose tested, which when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 5308. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and no match was found. However, the Panel noted that traces of ■■■■■, used in the manufacture of the triacylglycerol lipase, may be found in the food enzyme. The Panel considered that the risk of allergic reactions upon dietary exposure could not be excluded, particularly in individuals sensitised to fish. 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.
