Quality Evaluation of Clausena lansium from Different Geographical Origins Based on Principal Component Analysis and Cluster Analysis
摘要
Abstract
To explore the differences in the functionality and processing characteristics of Clausena lansium varieties from different regions,the physicochemical properties,polyphenolic substances,and antioxidant capacities of six C.lansium varie-ties were determined.Principal component analysis and cluster analysis were used for quality evaluation and classification of these six varieties.The results showed that the soluble solids content and total acid content of the six C.lansium varieties ranged from 12.4%to 18.4%and 1.44 to 10.15 g·kg‒1,respectively.Among them,Bingtang C.lansium had the lowest contents of soluble solids and total acids.The total phenolic content varied among different parts of C.lansium,and the total phenolic content of the peel was higher than that of the pulp in all varieties.Maoming Jixin C.lansium had the highest total phenolic content(1 384.0 mg GAE·hg‒1 in peel and 464.0 mg GAE·hg‒1 in pulp)and exhibited strong antioxidant capacity.The determination of phenolic substances in C.lan-sium showed that the rutin contents in peel and pulp were 115.4-224.3 mg·kg‒1 and 7.01-66.9 mg·kg‒1,respectively;the epicatechin contents in peel and pulp were 0.11-11.40 mg·kg‒1 and 0.11-6.16 mg·kg‒1,respectively;and the chlorogenic acid contents in both peel and pulp were less than 1 mg·kg‒1.Principal component analysis was performed on 17 indicators of C.lansium,and the results indicated that the comprehensive quality evaluation of C.lansium could be expressed by three principal components(cumulative contribution rate reaching 94.243%).Among them,Maoming Jixin C.lansium had the highest comprehensive score,while Bingtang C.lansium had the lowest score.Cluster analysis classified the six C.lansium varieties into four categories.In conclusion,Maoming Jixin C.lansium,which has the highest total phenolic content,strong antioxidant capacity,and the highest comprehensive score,is suitable for further research on the development of functional foods.关键词
