Abstract

Abstract

In order to get the maximal extraction content of cholesterol in oil, the effect of different extraction solvents, saponification temperature, saponification time and consistency of KOH-C2H5OH were discussed to optimize the cholesterol extraction conditions with the response surface methodology. Then the authors got the optimal conditions as follows: the extraction solvent was N-hexane, the extraction temperature was 67℃, the extraction time was 60min, the consistency of KOH-C2H5OH was 0.9 mol/L.
