摘要
以葡萄发酵后的葡萄籽粉碎物为试材,采用浸提方法,研究了浸提温度、时间、料液比、乙醇浓度对发酵后葡萄籽中原花青素提取率的影响。结果表明:4个因素的影响顺序为料液比>提取温度>提取时间>乙醇浓度。原花青素提取工艺的最佳条件为提取温度为40℃、提取时间为90min、料液比为1∶28g/mL、乙醇浓度为60%,提取率为3.05%。
Taking fermented grape seeds as material,using extraction method,the effect of extraction temperature,time,solid-liquid ratio,alcohol concentration on fermentation anthocyanin extraction yield of grape seeds after the central plains was studied.The results showed that the influence of four factors order was solid-liquid ratio〉extraction temperature〉extraction time〉ethanol concentration.The best condition of extraction process of procyanidins was extraction temperature 40℃,the extraction time was 90 min,material liquid ratio was 1∶28g/mL,ethanol concentration was 60%,the extraction yield was 3.05%.
