基于主成分分析与聚类分析的芜菁肉质根质地品质综合评价
Comprehensive evaluation of the texture quality of turnip succulent root based on principal component analysis and cluster analysis
摘要
Abstract
To scientifically evaluate the texture quality of succulent roots from different turnip cultivars and establish an evaluation method,this study measured succulent roots of 57 turnip cultivars using texture analyzer techniques in-cluding puncture method,shear method,and texture profile analysis(TPA).Correlation analysis among texture pa-rameters was conducted,followed by comprehensive evaluation through principal component analysis(PCA)and cluster analysis.Results revealed significant differences in texture quality among varieties:maximum adhesive force showed the greatest coefficient of variation(CV=84.98％),while elasticity exhibited the smallest difference(CV=7.74％).Correlations of varying degrees were observed among texture parameters.PCA simplified 12 texture indica-tors into five principal components,namely palatability factor,shear factor,puncture factor,adhesion factor,and epidermal hardness factor,a model for evaluating the textural quality of turnip succulent roots was developed.Cluster analysis categorized the 57 turnip cultivars into three groups:Group Ⅰ(low hardness with high adhesiveness),Group Ⅱ(high hardness with low adhesive force),and Group Ⅲ(high gumminess and chewiness).关键词
