食品伙伴網(wǎng)訊  2019年10月22日，歐盟食品安全局（EFSA）發(fā)布關(guān)于來自芽孢桿菌菌株M3‐1的β-半乳糖苷酶（β-Galactosidase）安全性的評估結(jié)果。

 

　　據(jù)了解，芽孢桿菌菌株M3‐1由GenoFocus Inc.公司生產(chǎn)。這種食品酶旨在用于生產(chǎn)低聚半乳糖（Galactooligosaccharides，GOS）。經(jīng)過評估，專家小組得出結(jié)論，這種食品酶在預(yù)期使用條件下不會引起安全問題。

 

　　部分原文報道如下：

 

　　The food enzyme β‐d‐galactosidase galactohydrolase （EC 3.2.1.23） is produced with Bacillus sp. strain M3‐1 by GenoFocus Inc. The food enzyme β‐galactosidase is intended to be used in the manufacture of galactooligosaccharides （GOS）。 Since residual amounts of total organic solids are removed by the purification steps applied during the production of GOS, toxicological studies were considered not necessary and no dietary exposure was calculated. Similarity of the amino acid sequence of the food enzyme to those of known allergens was searched and no match was found. The Panel considered that, under the intended conditions of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood of such reactions to occur is considered to be 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.
