新疆不同地区厚皮甜瓜“纳斯蜜”营养品质比较

以新疆阿勒泰、喀什、吐鲁番这3个地区相同种植模式下的厚皮甜瓜“纳斯蜜”为主要试材,对甜瓜主要的品质指标进行测定分析,比较不同地区同一品种甜瓜的品质差异,并利用隶属函数法对其进行综合评价。结果表明,蔗糖、果糖、葡萄糖、VC、可溶性蛋白质、总酚、类黄酮和苹果酸含量均以吐鲁番地区出产的甜瓜为最优,柠檬酸含量以喀什地区出产的甜瓜最高,阿勒泰地区甜瓜的富马酸含量及ABTS自由基清除率和DPPH自由基清除率最高。隶属函数分析结果表明,吐鲁番地区甜瓜品质最佳,其余两个地区较佳。

Comparison on Nutritional Qualities of Muskmelons 'Nasmi' in Different Regions of Xinjiang

The thick-skinned melons‘Nasmi’under the same planting pattern grown in Xinjiang Altay,Kashgar,and Turpan were used as the main test materials,and their main quality indicators were measured and analyzed to compare the differences,which was further comprehensively evaluated using membership function method.The results showed that sucrose,fructose,glucose,vitamin C,soluble proteins,total phenols,flavonoids and malic acid of melons were optimum in Turpan,while the citric acid content was the highest in Kashgar.In Altai region melons showed the strongest scavenging activities on ABTS and DPPH free radicals with the highest fumaric acid content.Membership function analysis showed that the qualities of muskmelons in Turpan area were better than that in the other two regions.
