Optimization of supercritical CO_2 extraction of grape seed oil via response surface methodology

Zhao Jun

Abstract

The optimization of supercritical CO2 extraction of grape seed oil was detrmined by\single factor experiments and response surface analysis.The results showed that the optimal extraction conditions were as follows:temperature 47℃,pressure 33 MPa,and average particle diameter 0.29 mm.Under these conditions the average grape seed oil extraction rate could reach to 92.3%.
