Nutritional Quality Analysis of Auricularia auricula in 4 Producing Areas
摘要
Abstract
In order to explore the differences of conventional nutrients,trace elements and amino acids in Auricularia auricula from different producing areas so as to provide technical reference for the nutritional quality analysis of A.auricula,the nutrients in A.auricula variety Heiwei 15 from four different producing areas,Yanji City,Mudanjiang City,Zhashui County,and Zhuoni County,were analyzed by single factor analysis of variance,correlation analysis and NMDS analysis.Results showed that contents of ether extract,crude fiber,crude polysaccharide,potassium,copper and calcium in Yanji A.auricula were the highest,and their contents were significantly higher than those in the other three producing areas.Contents of magnesium,manganese and iron in Mudanjiang A.auricula were significantly higher than those in the other three producing areas.Contents of zinc and vitamin B2 in Zhashui A.auricula were significantly higher than those in the other three producing areas.Contents of ash,crude protein and total amino acid in Zhuoni A.auricula were significantly higher than those in the other three producing areas.18 amino acids were measured in A.auricula,including 8 essential and 10 non-essential amino acids.Glutamic acid had the highest content,followed by aspartic acid,while methionine had the least.The analysis of amino acid contents revealed that savory amino acids had the highest content,followed by sweet-tasting amino acids,with bitter-tasting amino acids being the least abundant.Threonine,phenylalanine+tyrosine showed excess,and methionine+cysteine were the limiting amino acids.A.auricula from all four producing areas exhibited a fresh-sweet flavor and could be considered both food and medicinal mushrooms.Pearson correlation and NMDS analysis revealed varying degrees of correlation between conventional nutrients,trace elements,and amino acids among the four areas,A.auricula from Yanji City was the most nutritious,followed by that from Zhuoni County,while the A.auricula from Zhashui County had the lowest nutritional quality.关键词
