6种鲜食葡萄营养成分比较分析

Comparison and analysis of nutritional components of 6 kinds of table grapes

目的比较我国6种鲜食葡萄主栽品种营养成分的差异。方法采用理化分析方法对葡萄的氨基酸等营养成分进行测定,采用统计学方法比较分析品种间的营养差异。结果6种鲜食葡萄的脂肪、灰分、纤维、总酸、半胱氨酸、甘氨酸和磷含量差异不显著(P>0.05);夏黑葡萄的蛋白、总糖、还原糖、总花色苷、维生素C、必需氨基酸、风味氨基酸、支链氨基酸、药用氨基酸、增香与着色氨基酸、伯胺基氨基酸、K、Fe和Cu的含量均最高;巨玫瑰的总黄酮、总多酚、Ca、Mg和Mn的含量均最高;红地球的氨基酸比值系数评分和P含量最高,氨基酸营养均衡性最佳。结论不同品种鲜食葡萄营养差异明显,具有不同的潜在开发应用价值。

Objective To compare the differences in nutritional components of six main varieties of table grapes in China.Methods The amino acid and other nutrients of grapes were determined by physical and chemical analysis methods,and the nutritional differences between varieties were compared and analyzed by statistical methods.Results The differences of contents of fatty,ash,fiber,total acid,cysteine,glycine,and phosphorus in six kinds of table grapes were not significant(P>0.05).The content of protein,total sugar,reducing sugar,total anthocyanins,vitamin C,essential amino acid,flavoring amino acid,branched chain amino acid,medical amino acid,flavoring and coloring amino acid,primary amine amino acid,K,Fe,and Cu in Summer Black grape were all highest.The contents of total flavonoids,total polyphenols,Ca,Mg,and Mn in Muscat Kyoho grape were all highest.Red globe grape had the highest amino acid ratio coefficient score and P content,and the amino acid nutritional balance was best.Conclusion Different varieties of table grapes have obvious nutritional differences and different potential development and application value.
