2024年12月12日,欧盟食品安全局就一种食品酶内切-1,4-β-木聚糖酶(endo-1,4-β-xylanase)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绿木霉菌株HBI-TX01生产的,旨在用于4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 endo-1,4-β-xylanase (4-β-d-xylan xylanohydrolase; EC 3.2.1.8) is produced with Trichoderma citrinoviride strain HBI-TX01 by HBI Enzymes Inc. The food enzyme is free from viable cells of the production organism. It is intended to be used in four food manufacturing processes. Since residual amounts of food enzyme–total organic solids (TOS) are removed in two food manufacturing processes, dietary exposure was calculated only for the remaining two processes. It was estimated to be up to 1.488 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not indicate 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 1101 mg TOS/kg bw, the highest dose tested, which when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 740. A search for homology of the amino acid sequence of the food enzyme to known allergens was made and no match was found. Known sources of food allergens were used in the manufacturing process. The Panel considered that the risk of allergic reactions upon dietary exposure to this food enzyme 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.
