摘要
对江苏省镇江市句容地区的5个葡萄品种的出汁率,可溶性固形物、总酚、总花色苷含量,酚类物质种类和含量及体外抗氧化活性进行了分析。结果表明:5个品种葡萄果实出汁率范围为67.5%～74.6%,白罗莎的出汁率最高;可溶性固形物含量范围为16.1～18.6°Brix;巨峰的总糖、总酸、总酚和总花色苷含量分别为:173.36 g葡萄糖/L、2.40 g酒石酸/L、180.97 mg没食子酸/L、38.66 mg锦葵色素-3-葡萄糖苷/L,均显著高于其他4个葡萄品种(P<0.05)。巨峰和夏黑的抗氧化活性显著高于其他品种(P<0.05)。巨峰中酚酸和花色苷含量较高,夏黑中芦丁含量较高。总的来说,巨峰风味好,营养价值高,除用作鲜食外,还适宜加工制作红葡萄汁。白罗莎的营养成分和酚类物质含量均较低,其他品种(夏黑、美人指、无籽巨峰)的各项成分指标基本处于中等水平,但各具特色,宜作鲜食。
The yields of juices, soluble solids contents, total phenolic contents, types, and their antioxidant capacities, as well as total anthocyanins contents of five grape varieties were studied in this paper. The results revealed that the yields of juices of these five grapes were in a range of 67.5%-74.6%, with ’Rosario Bianco’ had the highest yield. The total soluble solids contents of these grape were in a range of 16.1-18.6 °Brix.‘Kyoho’ had the highest contents of total sugar(173.36 g glucose/L), total acid(2.4 g tartaric acid/L), total phenolics(180.97 mg gallic acid/L), and total anthocyanins(38.66 mg malvidin-3-glucoside/L)(P<0.05). The antioxidant capacities of ‘Kyoho’ and ‘Summer Black’ were higher than other varieties(P<0.05).‘Kyoho’ had considerably high contents of phenolic acids and anthocyanins.‘Summer Black’ had higher contents of rutin. Overall,‘Kyoho’ had good flavor and high nutritional values. It was suitable to be consumed as a fruit, as well as being processed to red grape juices. The amounts of nutrients and pheonlic compounds were less abundant in ‘Rosario Bianco’, and the remaining varieties(‘Summer Black’,‘Manicure Finger’,‘Kyoho Seedless’) were generally in the middle, and had their own characteristics and were suitable for direct consumption.
