全球短訊！歐盟評估一種食品酶葡聚糖1，4-α-葡萄糖苷酶的安全性

據了解，這種食品酶是由非轉基因少根根霉菌株AE-G生產的，旨在用于烘焙工藝、咖啡加工和酶改性乳制品配料制造中。

經過評估，專家小組認為，在預期的使用條件下（蒸餾酒精生產除外），不能排除飲食暴露引起過敏反應的風險，但這種情況發生的可能性很低。根據所提供的數據，小組得出結論，該食品酶在預期的使用條件下用于烘焙過程時不會引起安全隱患。部分原文報道如下：

The food enzyme glucan 1,4-α-glucosidase (4-α-d-glucan glucohydrolase; EC 3.2.1.3) is produced with the non-genetically modified Rhizopus arrhizus strain AE-G by Amano Enzyme Inc. The food enzyme is free from viable cells of the production organism. The applicant proposed the use of the food enzyme in baking processes, coffee processing and manufacture of enzymatically modified dairy ingredients (EMDI). The Panel considered only the baking processes as the relevant intended use of this food enzyme. Dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.94 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 a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level of 1,868 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 1,987. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and one match was found. The Panel considered that under the intended conditions of use the risk of allergic reactions by 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 when used in baking processes under the intended conditions of use.
