摘  要:
本试验在121℃条件下,采用不同灭菌时间对不同包装规格的SPF鸡饲料进行高压蒸汽灭菌处理,通过细菌培养和灭菌指示剂对不同处理后饲料的灭菌效果进行检查,以确定饲料最短有效灭菌时间。结果表明,饲料包装尺寸影响高压蒸汽灭菌效果,在包装尺寸合理的前提下,经121℃、20min高压蒸汽处理过的饲料,在30d的保存期内未检测到细菌,可以满足SPF鸡饲料的灭菌要求,生物灭菌指示剂试验得出同样结果。

摘  要:
The specific pathogen free(SPF)chicken's feed was sterilized by high pressure steam under 121 ℃ with different size and shape of the feed package,and the optimum condition was determined.The results showed:the size and shape of feed package had potent effects on sterilization.Under the condition of the appropriate size and shape of the package,SPF chicken feed should be considered to be sterilized completely by steam of 121℃ for 20 min,and it showed the same results when sterilization indicator was used.
