中文摘要:

      目的 分析评价魏营西瓜营养品质, 探究魏营西瓜的营养成分。方法 以魏营2个西瓜主产地的“美都”西瓜为研究对象(S1和S2), 以其他2个产地的同品种西瓜为对照(S3和S4), 检测分析4个产地西瓜中的糖、有机酸、氨基酸、矿物质元素、可溶性固形物、β-胡萝卜素、番茄红素和维生素C等营养指标。结果 不同产地西瓜营养品质存在一定差异性, 西瓜中糖组分以葡萄糖和果糖为主、有机酸以苹果酸和柠檬为主、游离氨基酸以瓜氨酸为主, 并含丰富矿物质元素; S1和S2的葡萄糖含量、糖酸比和甜酸比均高于S3和S4, 总酸含量则相反; S1和S2的瓜氨酸、β-胡萝卜素、番茄红素和维生素C的含量也均分别高于S3和S4; 基于主成分分析, S1和S2营养品质综合表现均优于S3和S4。结论 魏营西瓜具有更好的风味口感, 更丰富的营养成分, 营养品质更佳。

英文摘要:

      Objective To study the nutritional components of Weiying watermelon foranalyze and evaluate the nutritional quality of Weiying watermelon. Methods Namely “Meidu” watermelon from 2 main production areas of Weiying watermelon (S1 and S2) were used as experimental materials, and the same variety of watermelon from two other production areas (S3 and S4) as controls. The content of sugar, organic acid, amino acid, mineral, soluble solid, β-carotene, lycopene and vitamin C in the watermelons from the 4 production areas were detected and analyzed. Results The watermelon from different producing areas exhibited certain variations in quality characteristics. The sugar components in watermelon was mainly glucose and fructose, organic acids was mainly malic acid and lemon, free amino acids was mainly citrulline, and it also contains abundant mineral elements; the glucose content, sugar-acid ratio and sweetness-sourness ratio in S1 and S2 were higher than those in S3 and S4, while the total acid content was the opposite. In addition, the levels of the citrulline, β-carotene, lycopene and vitamin C in S1 and S2 were also higher than those in S3 and S4, respectively. The comprehensive performance of the nutritional quality of S1 and S2 were superior to that of S3 and S4 based on the principal component analysis. Conclusion Weiying watermelon has better flavor and texture, richer nutritional components, and superior nutritional quality.
