Abstract
[Objectives]The needs of determining nutrition in the specialized pet food were addressed to provide reference for optimization of rapid detection technology for nutritional components in pet feed.[Meth-ods]The content of crude fat in the commercial canned food and freeze-dried food for pets was determined with the Soxhlet extraction method and filter bag method.The differences in results of detection,coefficient of varia-tion,and ease of operation between two methods were compared.[Results]there was no significant difference between the results of detection with the two methods(P＞0.05),and the coefficients of variation were both less than 3%,indicating that the consistency of the results of detection is good.The filter bag method had a simpler operation and a more than 40%shorter cycle of detection.[Conclusions]Both Soxhlet extraction method and fil-ter bag method can accurately determine the content of crude fat in the canned food and freeze-dried feed for pets.The filter bag method has the advantages of high efficiency and convenience while maintaining the accu-racy of detection,making it more suitable for the needs of batch determining for large-scale pet feed enterprises.关键词
