Abstract:
This article chooses 4 kinds of different Grapes, detects their physical index and nutrition composition, and uses fuzzy comprehensive evaluation method to evaluate the typical types of Xinjiang grapes. Evaluate the grapes by 5 different kinds of factor model, and analyze their quality comprehensively. The results are as follows: Obviously, different kinds of Xinjiang grapes vary from one index to another, such as the difference of soluble solids content between Seedless white grapes and Horse-milk wine can reach at least 10%. Take spike weight, kernel weight, soluble sugar, total acid, Vc, protein, amino acids, dietary fiber, sugar acid ratio and the like as grape quality evaluation elements to establish Xinjiang grapes fuzzy comprehensive evaluation model; Five models are built by different main points. By calculating the detecting results of Xinjiang grapes, and analyzing them, there is a conclusion that the predominant grapes in Xinjiang, the Seedless white grapes (two groups of rank optimal 0.8662, 0.7364) and Munage grapes (three groups of rank optimal 0.7508, 0.7908, 0.6345), have more obvious advantages in the comprehensive evaluation, and the research will be a valuable reference for further Xinjiang grape development.
