Selection of evaluation factors for mango fruit quality.

[Objective] The quality evaluation factors of mango fruit were simplified to provide theoretical references for the establishment of mango quality indexes. [Method] Nineteen quality parameters from eighteen varieties of mango fruit in Guangxi areas, including fruit shape index, flesh firmness, contents of total soluble solids, titratable acid (TA), soluble sugar (SS ), flavor, etc, were measured. The data were analyzed by principal component analysis, systematic cluster analysis, and rationalization satisfaction index and the consolidating rule of multidimensional value theory, after which quality evaluation factors of the mango fruit were filtered. [Result] The results showed that there was either relative independence or close correspondence among the characteristics indicators of fruit quality. Seven indicators were selected according to the principal component scores. Based on the above results, 9 indicators for evaluating mango quality were obtained by systematic cluster analysis. Zill No.6, Zihua, Guire No.82, Guire No. 120, and Xiang-mang were selected for better quality varieties. The data of these 9 indicators of all tested fruits were analyzed with rationalization-satisfaction index and the consolidating rule of multidimensional value theory are suitable for selecting evaluation factors for mango fruit quality.
