基于隶属函数模型的新疆杏品质评价

Quality Evaluation of Xinjiang Apricot Based on Membership Function Model

摘要:

为了给新疆特色杏资源的开发提供理论依据和指导，本实验测定了新疆5个系列30个品种杏仁的物理指标、水分、灰分、蛋白质以及脂肪含量，并对30种杏仁油的脂肪酸成分和含量进行了详细的分析；在此基础上采用模糊综合评价法建立了杏仁营养结构的隶属函数模型，并对30种不同杏仁的营养成分和品质进行了全面的评价。结果表明：30个新疆杏品种杏仁蛋白质含量为17.78%~30.52%，脂肪含量为28.04%~53.87%；杏仁油中饱和脂肪酸平均含量为8.39%，不饱和脂肪酸平均含量为91.61%，不同品种之间的成分含量存在较大的差异。通过聚类分析和隶属函数模型综合分析发现胡安娜，阿克乔尓潘，色买提王，阿克阿依和克其克胡安娜等品种具有较好的杏仁品质和推广价值，应加大此类新疆特色杏资源品种的种植与综合开发利用。

Abstract:

In order to provide theoretical basis and guidance for the development of Xinjiang apricot resources, 30 varieties of apricots in 5 series of Xinjiang were studied. Their physical indices and contents of moisture, ash, protein and fat were determined, with fatty acid composition and total content of apricot oil being analyzed in detail. On the basis of these results, the membership function model of apricot nutrient structure was established using the fuzzy comprehensive evaluation method, and the nutrient composition and quality of 30 different apricots were comprehensively evaluated. The results showed that Xinjiang apricots had a protein content of 17.78%~30.52% and fat content of 28.04%~53.87%. The apricot oil had an average content of saturated fatty acids of 8.39% and unsaturated fatty acids of 91.61%. A large difference was found in the component contents between different varieties. Through cluster analysis and the comprehensive analysis of membership function models, it was found that Juana, Akchoapan Pan, Sematy King, Akyayi and Kuchke Juana varieties had relatively high apricot quality and potential for promotion. It is recommended to increase the planting and comprehensive development and utilization of such characteristic apricot varieties of Xinjiang.
