The genetic modifications do not give rise to safety concerns. The production strain meets the requirements for the qualified presumption of safety (QPS) approach. The food enzyme is free from viable cells of the production organism and its DNA. It is intended to be used in four food manufacturing processes. Since residual amounts of total organic solids (TOS) are removed during one food manufacturing process, dietary exposure was only calculated for the remaining three processes. Exposure was estimated to be up to 0.463 mg TOS/kg body weight per day in European populations. Given the QPS 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 homology of the amino acid sequence of the food enzyme to known allergens was made and no match was found. The Panel considered that the risk of allergic reactions upon dietary exposure cannot be excluded, but 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. 本文由食物火伴网食物资讯中间编纂，供网友参考，有任何疑问，请联系news@foodmate.net。
