摘要
为了研究不同产区黑木耳基于氨基酸含量的品质差异,本研究以市售15个产区的黑木耳为研究对象,以黑木耳中所含的17种氨基酸含量作为评价指标,进行主成分分析和聚类分析。结果表明:从17个评价指标中提取出了4个主成分,累计方差贡献率达到89.674%,可较好地反映出市售15个产区黑木耳的综合信息,分析得出Phe、Arg、Pro、Met和Ser含量可以作为市售15个产区黑木耳的综合评价指标。隶属函数法评价出市售15个产区黑木耳基于氨基酸含量的品质优劣顺序为:黑龙江>辽宁>西藏>内蒙古>陕西>江西>浙江>河北>吉林>新疆>贵州>云南>湖北>甘肃>四川。聚类分析将市售15个产区黑木耳划分为三大类。第I类包括黑龙江、辽宁和西藏3个产区,其综合评分较高;第Ⅱ类包括,内蒙古、陕西、江西、浙江、河北、吉林、新疆、贵州、云南、湖北和甘肃11个产区,其综合评分居中;第Ⅲ类包括四川1个产区,其综合评分较低。
To investigate the quality difference of Auricularia auricular-judaefrom different producing areas, Auricularia auricular-judaefor sale from 15 producing areas were used to tested materials in this study, 17 amino acid contents in Auricularia auricular-judae were used to assessing index, which were analyzed by principal component analysis and clustering analysis. Results showed that 4 principal components were extracted from 17 assessing index, their accumulative variance comtribution rate reached 89.674%, and could reflect preferably comprehensive information of Auricularia auricular-judae from 15 producing areas. Phe, Arg, Pro, Met and Ser contents could be comprehensive assessing index of Auricularia auricular-judaefor sale from 15 producing areas. The order of Auricularia auricular-judaequality from good to bad based on amino acid content of Auricularia auricular-judae for sale from 15 producing areas by subordinate fuction method was Heilongjiang>Liaoning>Xizang>Neimenggu>Shanxi>Jiangxi>Zhejiang>Hebei>Jilin>Xinjiang>Guizhou>Yunnan>Hubei>Gansu>Sichuan. Auricularia auricular-judaefor sale from 15 producing areas were divided into three classes by clustering analysis. Class I with higher comprehensive scores included 3 producing areas of Heilongjiang,Liaoning and Xizang. Class Ⅱ with medium comprehensive scores included 11 producing areas of Neimenggu, Shanxi,Jiangxi, Zhejiang, Hebei, Jilin, Xinjiang, Guizhou, Yunnan, Hubei and Gansu, Class Ⅲ with lower comprehensive scores included 1 producing area of Sichuan.
