據(jù)了解，這種食品酶是由米黑根毛霉菌株DSM 29547生產(chǎn)的，旨在用于奶酪生產(chǎn)的乳制品加工中。

 

　　經(jīng)過(guò)評(píng)估，專(zhuān)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(guò)敏和誘發(fā)反應(yīng)的風(fēng)險(xiǎn)，但除了對(duì)芥末蛋白過(guò)敏的人之外，這種風(fēng)險(xiǎn)被認(rèn)為是低的，但這種風(fēng)險(xiǎn)不會(huì)超過(guò)食用芥末的風(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(wèn)題。部分原文報(bào)道如下：

 

　　The food enzyme mucorpepsin (EC 3.4.23.23) is produced with the non-genetically modified Rhizomucor miehei strain DSM 29547 by Chr. Hansen. The food enzyme is free from viable cells of the production organism. It is intended to be used in dairy processing for cheese production. The dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.26 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 a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level of 618 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 2,400. A search for similarity of the amino acid sequence of the food enzyme to known allergens was made and three matches 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 is considered low except for individuals sensitised to mustard proteins, but this risk will not exceed that of mustard consumption. 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.
