據(jù)了解，這種食品酶是由非轉(zhuǎn)基因釀酒酵母菌株INV生產(chǎn)的，旨在用于四種食品制造過程：特種碳水化合物制造（轉(zhuǎn)化糖漿）、烘焙過程、蔗糖發(fā)酵飲料生產(chǎn)和糖果加工。

 

　　經(jīng)過評(píng)估，專家小組認(rèn)為，在預(yù)期的使用條件下，不能排除通過飲食接觸引起過敏反應(yīng)的風(fēng)險(xiǎn)，尤其是對(duì)番茄過敏的個(gè)體，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)，小組得出結(jié)論，該食品酶在預(yù)期的使用條件下不會(huì)引起安全問題。部分原文報(bào)道如下：

 

　　The food enzyme β-fructofuranosidase (β-d-fructofuranoside fructohydrolase; EC 3.2.1.26) is produced with the non-genetically modified Saccharomyces cerevisiae strain INV by DSM Food Specialties B.V. It is intended to be used in four food manufacturing processes: manufacture of specialty carbohydrates (invert sugar syrups), baking processes, production of sucrose-based fermented beverages and confectionary processes. The dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 2.51 mg TOS/kg body weight (bw) per day in European populations. Toxicological studies were not considered necessary, given the qualified presumption of safety status of the production strain and the nature of the manufacturing process. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and one match with a tomato allergen was found. The Panel considered that, under the intended conditions of use, the risk of allergic reactions upon dietary exposure to this food enzyme, particularly in individuals sensitised to tomato, cannot be excluded. However, the likelihood of allergic reactions to the β-fructofuranosidase from S. cerevisiae strain INV is expected not to exceed the likelihood of allergic reactions to tomato. As the prevalence of allergic reactions to tomato is low, also the likelihood of such reaction 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.
