Safety evaluation of the food enzyme triacylglycerol lipase from the genetically modified Komagataella phaffii strain DSM 34125
The food enzyme triacylglycerol lipase (triacylglycerol acylhydrolase; EC 3.1.1.3) is produced with the genetically modified Komagataella phaffii strain DSM 34125 by Chr. Hansen. The genetic modifications do not give rise to safety concerns. The food enzyme was considered free from viable cells of the production organism and its DNA. The food enzyme is intended to be used in four food manufacturing processes. Dietary exposure was estimated to be up to 0.039 mg total organic solids (TOS)/kg body weight per day in European populations. Given the qualified presumption of safety status of the production strain and the absence of concerns resulting from the food enzyme manufacturing process, toxicity tests were considered unnecessary by the Panel. A search for the homology of the amino acid sequence of the triacylglycerol lipase to known allergens was made and no match was found. The Panel considered that a risk of allergic reactions upon dietary exposure cannot be excluded, but that the likelihood is 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.

The EFSA Journal covers methods of risk assessment, reports on data collected, and risk assessments in the individual areas of plant health, plant protection products and their residues, genetically modified organisms, additives and products or substances used in animal feed, animal health and welfare, biological hazards including BSE/TSE, contaminants in the food chain, food contact materials, enzymes, flavourings and processing aids, food additives and nutrient sources added to food, dietetic products, nutrition and allergies.
