大连不同产地刺参营养成分分析与评价

Analysis and evaluation of nutrient components of sea cucumber from different places in Dalian

采用主成分分析和聚类分析法对大连13个不同产地刺参的蛋白质、灰分、脂肪、多糖、氨基酸、牛磺酸、皂苷、胶原蛋白等营养指标进行分析和评价。不同产地刺参营养成分综合得分由高到低排序依次为西部、广鹿岛、川蹄沟、獐子岛、海洋岛、皮口、瓦房店、庄河、小王岛、大长山、小长山、三十里堡和财神岛。13种不同产地刺参可分为四类:第一类刺参蛋白质和牛磺酸含量较高,分别产自西部、广鹿岛、川蹄沟和獐子岛;第二类刺参氨基酸总量、必需氨基酸和皂基含量较低,分布在排名最后的三十里堡和财神岛;第三类刺参多糖含量高,分别产自海洋岛、大长山、瓦房店和庄河;第四类刺参皂苷含量高,分别产自小长山、小王岛和皮口。上述结果可为不同刺参针对性的加工和利用提供理论依据。

The methods of principal component analysis and cluster analysis were used to analyze and evaluate the nutritional indicators of sea cucumbers from 13 different producing areas in Dalian,including protein,ash,crude fat,polysaccharide,amino acids,taurine,saponin,collagen,etc.Principal component analysis results showed that the ranking order of comprehensive nutrient scores from high to low was Xibu,Guangludao,Chuantigou,Zhangzidao,Haiyangdao,Pikou,Wafangdian,Zhuanghe,Xiaowangdao,Dachangshan,Xiaochangshan,Sanshilipu and Caishendao.13 kinds of sea cucumbers could be clearly divided into four categories by the cluster analysis method:Sea cucumbers from Xibu,Guangludao,Chuantigou and Zhangzidao were in the first category with relatively high content of protein and taurine.The second category has low contents of total amino acids,essential amino acids and saponins,which are distributed in Sanshilipu and Caishen island.Sea cucumbers from Haiyangdao,Dachangshan,Wafangdian and Zhuanghe were listed as the third category with the characteristic of high polysaccharide content.The fourth category was sea cucumbers from Xiaochangshan,Xiaowangdao and Pikou with high saponin content.The above results provide certain theoretical basis for the individually targeted processing and utilization of different sea cucumbers.
