摘要
Abstract
To recycle the valuable by product of the wine industry,supercritical carbon dioxide (CO2) extraction was used to extract oil with unsaturated fatty acids from the grape seeds.The goal was to test the extraction of grape seed oil by the supercritical CO2extraction technique.Single parameter experiments were designed to investigate the influence of extraction pressure,extraction temperature,CO2flow rate,and residence time.The extraction pressure was the main factor to affect the extraction yield.The optimal values of extraction temperature and CO2flow rate for the extraction yield of grape seed oil were obtained.The response surface experiments were designed based on the result of single parameter experiments.Central composite design(CCD)was chosen to find the optimal conditions for the extraction of grape seed oil.The multivariate regression equation was established and the variance analysis was carried out,The model P-value is less than 0.0001.At the optimal extraction conditions :28MPa for extraction pressure,321K for extraction temperature,15.5L/h for CO2flow rate,and 155 min for residence time,the extraction yield of 14.12% was achived.关键词
