據(jù)了解，這種食品酶是由非轉(zhuǎn)基因Rasamsonia composticola菌株427-FS生產(chǎn)的，旨在用于六種生產(chǎn)過(guò)程，即烘焙過(guò)程、其他基于谷物的過(guò)程、釀造過(guò)程、用于生產(chǎn)淀粉和谷蛋白部分的谷物處理、蒸餾酒精生產(chǎn)和酵母加工中。

 

　　經(jīng)過(guò)評(píng)估，專家小組認(rèn)為，在預(yù)期的使用條件下，不能排除通過(guò)飲食接觸引起過(guò)敏反應(yīng)的風(fēng)險(xiǎn)，但這種情況發(fā)生的可能性很低。根據(jù)所提供的數(shù)據(jù)，小組得出結(jié)論，該食品酶在預(yù)期的使用條件下不會(huì)引起安全問(wèn)題。部分原文報(bào)道如下：

 

　　The food enzyme endo-1,3(4)-β-glucanase (3-(1–3,1–4)-β-d-glucan 3(4)-glucanohydrolase; EC 3.2.1.6) is produced with the non-genetically modified Rasamsonia composticola 427-FS strain by Kerry Ingredients & Flavours Ltd. The food enzyme is free from viable cells of the production organism. The food enzyme is intended to be used in six manufacturing processes, i.e. baking processes, other cereal-based processes, brewing processes, grain treatment for the production of starch and gluten fractions, distilled alcohol production and yeast processing. Since residual amounts of total organic solids (TOS) are removed by distillation and during grain processing, dietary exposure was calculated only for the remaining four processes. It was estimated to be up to 0.809 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 866 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 1,070. 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 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 under the intended conditions of use.
