據(jù)了解，這種食品酶是由轉(zhuǎn)基因里氏木霉菌株NZYM-GV生產(chǎn)的，旨在用于谷物處理，以生產(chǎn)淀粉和面筋部分。

 

　　經(jīng)過(guò)評(píng)估，專家小組認(rèn)為，在預(yù)期的使用條件下，不能排除飲食暴露引起過(guò)敏和誘發(fā)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)，評(píng)估小組得出結(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 non-reducing end α-l-arabinofuranosidase (α-l-arabinofuranoside non-reducing end α-l-arabinofuranosidase; EC 3.2.1.55) is produced with the genetically modified Trichoderma reesei strain NZYM-GV by Novozymes A/S. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism and its DNA. It is intended to be used in grain treatment for the production of starch and gluten fractions. Since residual amounts of total organic solids (TOS) are removed by washing and purification steps applied during grain treatment, the estimation of a dietary exposure is considered not necessary. 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 1,116?mg TOS/kg body weight per day, the highest dose tested. Similarity of the amino acid sequence 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 for this to occur is considered to be low. based on the data provided and the removal of TOS during the grain treatment, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.
