Abstract
Based on the U.S. Food and Drug Administration regulations, O157:H7 is a pertinent pathogen in high acid juices that needs to be inactivated during the pasteurization process. The results of this study suggest that the effect of acid adaptation should be considered in the selection of HPP parameters for O157:H7 inactivation to ensure that pasteurization objectives are achieved.
摘要
基于美国食品和药物管理局的规定，O157:H7 是高酸性果汁中的一种相关病原体，需要在巴氏杀菌过程中灭活。本研究结果表明，在选择 HPP 参数以实现 O157:H7 灭活时，应考虑酸适应的影响，以确保达到巴氏杀菌目标。
