根据提供的新数据和以前的评估，专家小组得出结论，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 catalase (hydrogen-peroxide:hydrogen-peroxide oxidoreductase; EC 1.11.1.6) is produced with the non-genetically modified Aspergillus tubingensis strain AE-CN by Amano Enzyme Inc. The food enzyme is intended to be used in seven food manufacturing processes. In a previous evaluation, the Panel could not conclude on the safety of this food enzyme due to uncertainties about the absence of viable cells of the production organism in the food enzyme and to the clastogenic effects observed in the in vitro genotoxicity studies, which could not be dismissed due to limitations in the in vivo studies. In this assessment, the Panel evaluated new data provided by the applicant and completed the safety evaluation of this food enzyme. The new data demonstrated the absence of viable cells of the production organism in the food enzyme and showed no concerns on genotoxicity. based on the new data provided and the previous evaluation, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.
