2024年4月17日，欧盟食品安全局就一种蛋白酶oryzin的安全性评价发布意见。
据了解，这种食品酶是由非转基因赭曲霉菌株AE-P生产的，旨在用于九种食品制造过程。
经过评估，专家小组认为，在预期的使用条件下，不能排除饮食暴露引起过敏反应的风险，别是对甜瓜过敏的人，但不会超过食用这种食品的风险。根据所提供的数据，评估小组得出结论，这种食品酶在预期使用条件下不会引起安全问题。部分原文报道如下：
The food enzyme oryzin (EC 3.4.21.63) is produced with the non-genetically modified Aspergillus ochraceus strain AE-P by Amano Enzyme Inc. The food enzyme was considered free from viable cells of the production organism. It is intended to be used in nine food manufacturing processes. The dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.1 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not raise 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 1862 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 18,620. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and 31 matches were found, including one food allergen (melon). The Panel considered that the risk of allergic reactions upon dietary exposure to this food enzyme, particularly in individuals sensitised to melon, cannot be excluded, but would not exceed the risk from consumption of this food. 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.
