  经过评估,专家小组认为,在预期的使用条件下,不能排除饮食暴露引起过敏反应的风险,但这种可能性很低。根据所提供的数据,小组得出结论,这种食品酶在预期使用条件下不会引起安全问题。部分原文报道如下:
  The food enzyme peroxidase (phenolic donor: hydrogen-peroxide oxidoreductase, EC 1.11.1.7) is produced with the genetically modified Aspergillus niger strain MOX by DSM Food Specialties B.V. The genetic modifications do not give rise to safety concerns. The food enzyme is co nsidered free from viable cells of the production organism and its DNA. The food enzyme is intended to be used in whey processing. Dietary exposure to the food enzyme total organic solids (TOS) was estimated to be up to 0.635 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not indicate 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 2,162 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 3,405. 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 co nsidered that, under the intended co nditions of use, the risk of allergic reactions by dietary exposure cannot be excluded, but the likelihood is low. ba sed on the data provided, the Panel co ncluded that this food enzyme does not give rise to safety concerns, under the intended co nditions of use.
