Abstract:

This study aims to investigate the differences in nutritional components among various brands of Huangjiu lees. Three brands,Guyuelongshan,Kuaijishan,and Nü'erhong,were selected. The basic nutritional components,fatty acid,and amino acid contents of three brands were analyzed,and principal component analysis was conducted for all nutritional components. The results showed that Guyuelongshan lees had the highest ash and crude fiber content,whereas Kuaijishan lees had the highest levels of crude protein,crude fat,total acid,calcium,palmitic acid,linoleic acid,glutamic acid,and leucine. The results of principal component analysis indicated that two principal components were extracted from all nutritional components,with a cumulative variance contribution rate of 100.00%. The comprehensive scores of principal components of the three brands Huangjiu lees,from high to low,were Kuaijishan,Guyuelongshan,and Nü'erhong.

Key words: Huangjiu lees, feed, basic nutritional component, fatty acid, amino acid, principal component analysis, comprehensive evaluation
