| Abstract: | Procyanidins are the most effective natural antioxidant with the function of scavenging free radicals,anti-cancer and anti-aging.In this paper,cabernet sauvignon grape seeds were used as raw material to extract procyanidins by using ethanol adding Bmim ]Cl. Four factors, including extraction temperature,extraction time,ethanol concentration,and the ratio of liquid, were investigated to study their influence on the extraction efficiency of procyanidins.According to the results of single factor experiment,response surface experiment was designed to get the optimum parameters.The development of this technology will provide strong reference for the industrial production of procyanidin. |
