以4份厚皮甜瓜成熟果实为试材,于2013年7~8月,测定了果肉中可溶性固形物、可溶性糖、还原糖、蛋白质、果胶和维生素C等9类营养物质的含量,进行了材料间的差异性分析,并利用隶属函数法综合评价了其营养品质。结果表明:厚皮甜瓜成熟果实中各类营养物质含量和高低次序为:可溶性固形物(95.8mg/g)>可溶性糖(61.62mg/g)>还原糖(30.63mg/g)>果胶(3.99mg/g)>淀粉(1.46mg/g)>粗纤维(1.39mg/g)>蛋白质(0.52mg/g)>多糖(0.145mg/g)>维生素C(0.0601mg/g);材料间可溶性固形物、多糖、纤维素和维生素C含量达极显著差异水平,其余营养物质含量未达显著差异;材料“M-2”的隶属函数值最大,为0.8342,品质最优。
Four mature muskmelon fruits were used as material to measure the content of nine kinds of nutritious substances such as soluble solid, soluble sugar, reducing sugar, protein, pectin and vitamin C from July to August 2013 The analysis of the differences between the materials, and the use of membership function of a comprehensive evaluation of the nutritional quality. The results showed that the content of various nutrients and the order of high and low nutrient contents in mature fruits of melon were: soluble solid (95.8mg / g)> soluble sugar (61.62mg / g)> reducing sugar (30.63mg / g) 3.99mg / g)> starch (1.46mg / g)> crude fiber (1.39mg / g)> protein 0.52mg / g> polysaccharide 0.145mg / g> vitamin C 0.0601mg / g; The contents of soluble solids, polysaccharides, cellulose and vitamin C reached extremely significant differences, and the contents of other nutrients did not reach significant differences. The membership function value of material “M-2” was the highest, which was 0.8342, with the best quality.
