苹果特征性营养品质指标筛选
Screening study of apple nutritional quality indexes
摘要
Abstract
In order to solve the problem of the lack of fruit nutrition quality grading index,six apple varieties,Xinjiang Aksu red Fuji,Shandong Qixia red Fuji and Shaanxi Luochuan red Fuji,New Zealand Envy,New Zealand Rockit and Daning Qincui were taken as study materials.One-way analysis of variance(ANOVA)and calculation of the coefficient of variation of nutritional quality indexes were used to analyze the differences in the contents of sugar,acid,pectin,dietary fiber,vitamin C,minerals,proanthocyanidins,total anthocyanins,total phenols and total flavonoids in apples.The bivariate correlation analysis,principal fraction analysis and cluster analysis were used to screen the dimensionality reduction of the above 11 characteristic nutritional quality indicators.The results showed that:1)There were great differences in the taste,color and nutrients among the six apple varieties,especially the contents of vitamin C,proanthocyanidins and total anthocyanins,and the coefficients of variation reached 64.39％,51.84％and 48.93％,respectively.2)The nutritional indexes of apples were correlated and classifiable,and the contribution rate of the first four types of factors obtained after the dimension reduction of 11 nutritional indicators to the nutritional quality of apples was 99.795％,which could reflect the original index of 99.795％.3)One core index was identified from each of the four types of factors,namely total phenols(factor weight 0.941),water-soluble sugar(factor weight 0.926),vitamin C(factor weight 0.836)and total minerals(factor weight 0.16),which could be used as apple nutrition quality grading indicators.In conclusion,the method of screening characteristic nutritional quality indexes of fruits is feasible in the quality grading of fruits.关键词
