　　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。根据提供的数据，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隐患。部分原文报道如下：

　　The food enzyme catalase (hydrogen-peroxide:hydrogen-peroxide oxidoreductase; EC 1.11.1.6) is produced with the genetically modified Aspergillus niger strain DP-Azw58 by Danisco US, Inc. 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. It is intended to be used in egg processing. ba sed on the maximum use levels, dietary exposure to the food enzyme�Ctotal organic solids (TOS) was estimated to be up to 1 ��g 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 1,288 mg TOS/kg bw per day, the highest dose tested, which when compared with the estimated dietary exposure, results in a margin of exposure of at least 1.3 �� 106. A search for similarity of the amino acid sequence of the food enzyme to known allergens was made and one match was 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 for this to occur 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.
