摘要
对脱脂葡萄籽原花青素的提取工艺进行了研究,在单因素试验和正交试验的基础上,得出最佳提取条件:提取温度30℃,60%乙醇为提取液,调节提取液pH5,料液比1∶20,浸提两次,每次30min,提取率达到96.26%。粗提物中原花青素含量为52.64%。
In this paper, the extraction of proanthocyandins from defatted grape seeds was studied. The optimum process based on the single factor and orthogonal test was as the following： the temperature was 30℃, the concentration of ethanol 60%, pH value is 5.0, the rate of solvent to material is 20 ： 1, extraction time is 30 min twice. The extraction yield is up to 96.26% and the purity of the product is 52.64%.
