Abstract
Infectious pancreatic necrosis virus (IPNV) (serotype Sp) was exposed to temperatures between 60 and 90°C in a medium mimicking the water-soluble phase of hydrolyzed fish by-products. D values ranged from 290 to 0.5 min, and the z value was approximately 9.8°C. Addition of formic acid to create a pH 4 medium did not enhance heat inactivation. Predicted inactivation effects at different temperature-time combinations are provided.
摘要
传染性胰脏坏死病毒（IPNV）（血清型 Sp）在模拟水解鱼副产品水溶性相的介质中，于 60 至 90°C 的温度下暴露。D 值范围为 290 至 0.5 分钟，Z 值约为 9.8°C。添加甲酸以形成 pH 值为 4 的介质并不会增强热失活作用。提供了不同温度-时间组合下的预测失活效果。
