   食品伙伴网讯  2023年10月18日,欧盟食品安全局就一种食品酶三酰甘油脂肪酶(triacylglycerol lipase)的安全性评价发布意见。
 
  据了解,这种食品酶是由转基因琉球曲霉菌株FL108SC生产的,旨在以固定形式用于通过酯交换生产改性脂肪和油。
 
  经过评估,专家小组认为,在预期的使用条件下,不能排除通过饮食接触引起过敏反应的风险,但这种情况发生的可能性很低。根据所提供的数据,小组得出结论,该食品酶在预期的使用条件下不会引起安全问题。部分原文报道如下:
 
  The food enzyme triacylglycerol lipase (triacylglycerol acylhydrolase; EC 3.1.1.3) is produced with the genetically modified Aspergillus luchuensis strain FL108SC by Advanced Enzyme Technologies Ltd. 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 an immobilised form for the production of modified fats and oils by interesterification. Genotoxicity tests did not raise safety concerns. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rodents. The Panel identified a no observed adverse effect level (NOAEL) at the highest dose of 774 mg TOS/kg body weight per day. As the food enzyme is used in an immobilised form and as any residual amounts of the food enzyme-total organic solids (TOS) are removed during the food manufacturing process, dietary exposure was not calculated. 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 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.
