2024年5月17日，歐盟食品安全局就一種漆酶（laccase）的安全性評(píng)價(jià)發(fā)布意見。
據(jù)了解，這種食品酶是由非轉(zhuǎn)基因毛栓菌菌株AE-OR生產(chǎn)的，旨在用于六種食品制造過程。
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)，但這種可能性被認(rèn)為很低。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 laccase (benzenediol:oxygen oxidoreductase; EC 1.10.3.2) is produced with the non-genetically modified Trametes hirsuta strain AE-OR by Amano Enzyme Inc. The food enzyme is free from viable cells of the production organism. It is intended to be used in six food manufacturing processes. Dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 0.026 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not raise 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 862 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 33,154. 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 a 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.
