　　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，专家小组的结论是，在预期的使用条件下，这种食品酶不会引起安全问题。部分原文报道如下：

　　The food enzyme with glucan 1,4�?alpha;‐glucosidase (EC 3.2.1.3) and ��‐amylase (EC 3.2.1.1) activities is produced with the genetically modified strain of Aspergillus niger NZYM‐BX by Novozymes A/S. 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 food enzyme is intended to be used in starch processing for the production of glucose syrups and distilled alcohol. Since residual amounts of total organic solids are removed by distillation and by the purification steps applied during the production of glucose syrups, dietary exposure was not calculated. Genotoxicity tests did not raise a safety concern. The repeated dose 90‐day oral toxicity study in rats made with a substitute enzyme was not co nsidered suitable. However, since no exposure was expected from the intended uses, this study was not co nsidered necessary. Similarity of the amino acid sequence of the food enzyme to those of known allergens was searched and two matches were found. The Panel co nsidered that, under the intended co nditions of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood is co nsidered to be low. ba sed on the data provided, the Panel co ncluded that this food enzyme does not give rise to safety co ncerns under the intended co nditions of use.
