中文摘要: 该文对云南大理宾川县葡萄籽原花青素提取物进行体外抗氧化活性研究，并将其制备成一种果汁饮料。抗氧化试验结果表明，当葡萄籽原花青素浓度为1 mg/mL时，对1，1-二苯基-2-三硝基苯肼（1，1-diphenyl-2-picrylhydrazyl radical，DPPH）自由基清除率为94.49%；浓度为15mg/mL时，对2，2'-联氮-双-3-乙基苯并噻唑啉-6-磺酸阳离子[2，2'-azino-bis（3-ethylbenzothiazoline-6-sulfonic acid）cation，ABTS+]自由基清除率可达 99.42%；浓度超过 5 mg/mL 时，其还原力高于VC。葡萄籽原花青素果汁饮料最优配方为葡萄汁添加量41.62 g/100 g、葡萄籽原花青素添加量0.5 g/100 g、柠檬酸添加量0.12 g/100 g、白砂糖添加量6 g/100 g，在此配方下葡萄籽原花青素果汁饮料综合评分为76.31。
Abstract:This paper studied the in vitro antioxidant activity of proanthocyanidin extracts of grape seed from Binchuan，Dali，Yunnan province，and prepared it into a fruit juice beverage.The results of antioxidant test showed that the 1，1-diphenyl-2-picrylhydrazyl radical（DPPH）free radical scavenging rate was 94.49%when the concentration of grape seed proanthocyanidinwas 1 mg/mL.The scavenging rate of 2，2'-azino-bis（3-ethylbenzothiazoline-6-sulfonic acid）cation（ABTS+）radicals was up to 99.42%when the concentration was 15 mg/mL.The reducing power was higher than that of VCwhen the concentration exceeded 5 mg/mL.The optimal formula of the juice beverage with grape seed proanthocyanidins was 41.62 g/100 g grape juice addition，0.5 g/100 g grape seed proanthocyanidin，0.12 g/100 g citric acid，and 6 g/100 g white sugar.The comprehensive score of the juice beverage with grape seed proanthocyanidins under this formula was 76.31.
