| Abstract: | The refinement technics of grape seed crude oil by the technology of supercritical CO2 extraction(SFE-CO2) had been studied.It conquered the disadvantages of complex process,remnant of impregnant,and the influence to the oil by the traditional processing.The results showed that the optimal condition to refine grape-seed crude oil by SFE-CO2 was extraction pressure 25Mpa,extraction temperature 40℃,extraction time 1.5h.The new technology was easy handled,and the refined-oil was good in quality,colour and scen... |
