據(jù)了解，這種食品酶是由非轉(zhuǎn)基因曲霉屬菌株FUA生產(chǎn)的，旨在用于3種食品生產(chǎn)過程。

　　

　　經(jīng)過評(píng)估，專家小組認(rèn)為，在預(yù)期的使用條件下，不能排除飲食暴露引起過敏反應(yīng)的風(fēng)險(xiǎn)。根據(jù)所提供的數(shù)據(jù)，評(píng)估小組得出結(jié)論，這種食品酶在預(yù)期使用條件下不會(huì)引起安全問題。部分原文報(bào)道如下：

　　

　　The food enzyme α-amylase (4-α-d-glucan glucanohydrolase; EC 3.2.1.1) is produced with the non-genetically modified Aspergillus sp. strain FUA by DSM Food Specialties B.V. The food enzyme is free from viable cells of the production organism. The food enzyme is intended to be used in four food manufacturing processes. Since residual amounts of food enzyme-total organic solids (TOS) are removed in the production of distilled alcohol, dietary exposure was calculated only for the remaining three food manufacturing processes. It was estimated to be up to 0.687 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 2000 mg TOS/kg bw per day, the highest dose tested, which when compared with the estimated dietary exposure, results in a margin of exposure of at least 2911. A search for the homology of the amino acid sequence of the food enzyme to known allergens was made and three matches with respiratory allergens were found, one of which is also an oral allergen. Known sources of allergens were used in the food enzyme manufacturing process. The Panel considered that 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.
