據(jù)了解，這種食品酶是由非轉(zhuǎn)基因百歲蘭曲霉菌株NZYM-KF生產(chǎn)的，旨在用于果糖多糖的加工中，以生產(chǎn)低聚果糖。

 

　　經(jīng)過評估，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，特別是對番茄過敏的人，但這種風(fēng)險不會超過食用番茄的風(fēng)險。根據(jù)所提供的數(shù)據(jù)，評估小組得出結(jié)論，這種食品酶在預(yù)期使用條件下不會引起安全問題。部分原文報道如下：

 

　　The food enzyme inulinase (1-β-d-fructan fructanohydrolase; EC 3.2.1.7) is produced with the non-genetically modified Aspergillus welwitschiae strain NZYM-KF by Novozymes A/S. The food enzyme is free from viable cells of the production organism. It is intended to be used in the processing of fructo-polysaccharides for the production of fructo-oligosaccharides. Since residual amounts of total organic solids (TOS) are removed during the food manufacturing process, toxicological studies other than allergenicity were considered unnecessary and 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 two matches with tomato allergens were found. The Panel considered that the risk of allergic reactions upon dietary exposure to this food enzyme, particularly in individuals sensitised to tomato, cannot be excluded, but is expected not to exceed that of tomato. As the prevalence of allergic reactions to tomato is low, also the likelihood of such reactions to occur to the food enzyme 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.
