&m88体育nbsp; 食品伙伴网讯  2023年7月24日，欧盟食品安全局就一种食品酶核糖核酸酶 P（ribonuclease P）的安全性评价发布意见。   据了解，这种食品酶是由非转基因桔青霉菌株AE-RP-4生产的，旨在用于生产酵母提取物的酵母加工。   经过评估，专家小组认为，在预期的使用条件下，不能排除通过饮食接触引起过敏反应的风险，但这种情况发生的可能性很低。根据所提供的数据，小组得出结论，该食品酶在预期的使用条件下不会引起安全问题。部分原文报道如下：   The food enzyme ribonuclease P (EC 3.1.26.5) is produced with the non-genetically modified Penicillium citrinum strain AE-RP-4 by Amano Enzyme Inc. It is intended to be used in yeast processing only for the production of yeast extract. Dietary exposure to the food enzyme total organic solids (TOS) was estimated to be up to 0.153 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not raise safety concerns. 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 (NOAEL) of 134.7 mg TOS/kg bw per day, which when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 880. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and no match was found. The Panel considered that, under the intended conditions of use, 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.   本文由食品伙伴网食品资讯中心编辑，供网友参考，有任何疑问，请联系[email protected]。
