據(jù)了解，這種食品酶是由大孢子黑曲霉變種菌株P(guān)TG8398生產(chǎn)的，旨在用于葡萄酒的生產(chǎn)加工。

 

　　經(jīng)過評估，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和誘發(fā)反應(yīng)的風(fēng)險，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)，評估小組得出結(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 with aspergillopepsin I (EC 3.4.23.18) and aspergillopepsin II (EC 3.4.23.19) activities is produced with a non-genetically modified Aspergillus niger var. macrosporus strain PTG8398 by Meiji Seika Pharma Co., Ltd. The food enzyme was considered free from viable cells of the production organism. It is intended to be used in wine production. based on the maximum use levels, dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.14 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 919 mg TOS/kg bw per day, the highest dose tested which, when compared with the estimated dietary exposure, results in a margin of exposure above 6,700. A search for similarity of the amino acid sequence of the food enzyme to known allergens was made and four matches with respiratory allergens were 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 for this to occur is considered 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.
