　　经过评估，专家小组认为，不能排除通过饮食接触引起过敏反应的风险，但这种情况发生的可能性很低。根据所提供的数据，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问题。部分原文报道如下：

　　The food enzyme endo-1,4-��-xylanase (4-��-D-xylan xylanohydrolase; EC 3.2.1.8) is produced with the genetically modified Bacillus subtilis strain DP-Ezd119 by Genencor Internatio nal B.V. The production strain meets the requirements for the qualified presumption of safety (QPS) approach. The genetic modifications do not give rise to safety concerns. The food enzyme was co nsidered free from viable cells of the production organism and its DNA. The food enzyme is intended to be used in the processing of cereals and other grains for the production of baked products. Dietary exposure was estimated to be up to 0.085 mg total organic solids/kg body weight per day in European populations. Given the QPS status of the production strain and the absence of co ncerns resulting from the food enzyme manufacturing process, toxicity tests were co nsidered unnecessary by the Panel. A search for the homology of the amino acid sequence of the endo-1,4-��-xylanase to known allergens was made, and no match was found. The Panel co nsidered that a risk of allergic reactions upon dietary exposure to the food enzyme 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 co ncerns under the intended co nditions of use.
