   食品伙伴网讯  2021年4月29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Aspergillus luchuensis strain FL100SC生产的,旨在用于通过酯交换生产改性脂肪和油的过程中。
 
  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的过敏性致敏和诱发反应的风险,但这种情况发生的可能性很低。根据所提供的数据、食品酶的固定和油脂加工过程中总有机固体的去除,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 a genetically modified Aspergillus luchuensis strain FL100SC 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. The triacylglycerol lipase is intended to be used only in an immobilised form in the production of modified fats and oils by interesterification. Since residual amounts of total organic solids (TOS) are removed by filtration and purification steps applied during fats and oils processing for interesterification, no dietary exposure was calculated. 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 (NOAEL) of 849 mg TOS/kg body weight (bw) per day, the highest dose tested. The similarity of the amino acid sequence of the food enzyme to those of known allergens was searched and no match was found. The Panel considers 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, including the immobilisation process and the absence of TOS in the final product, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.
