Revised dietary exposure assessment of the food enzyme triacylglycerol lipase from the genetically modified strain NZYM-FL.

The food enzyme triacylglycerol lipase (triacylglycerol acylhydrolase, EC 3.1.1.3) is produced with the genetically modified strain NZYM-FL by Novozymes A/S. A safety evaluation of this food enzyme was made previously, in which EFSA concluded that, under the intended conditions of use, this food enzyme did not give rise to safety concerns. Due to the implementation of a new methodology to estimate the dietary exposure to food enzymes in 2016, the European Commission requested EFSA to revise the exposure assessment of this food enzyme by using this new methodology. In this assessment, EFSA realigned the intended uses of this food enzyme to two food manufacturing processes and recalculated the dietary exposure. As the food enzyme-total organic solids (TOS) are removed in one food manufacturing process, the dietary exposure to the food enzyme-TOS was estimated only for the remaining process. It was calculated to be up to 0.492 mg TOS/kg body weight (bw) per day in European populations. When combined with the no observed adverse effect level previously reported (340 mg TOS/kg bw per day, the mid-dose tested), the Panel derived a margin of exposure of at least 691. Based on the revised exposure estimate, the margin of exposure calculated thereof and the previous evaluation, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.
