The Preparation of Granule Soya Lecithin from Soya Wet Gum

Abstract

Abstract: The granule Soya lecithin was purified by deoiling with acetone from Soya wet gum. The extraction parameters were studied. The effect of washing times, ratio of wet gum and solvent, water content in acetone, extraction time and temperature on the purity of lecithin have been described. Through orthogonal design the optimum conditions were determined. Under the condition of using anhydrous acetone, Soya lecithin can be made into granule Soya lecithin, which acetone insoluble can reach 98.5%.

Key words: granule Soya lecithin, acetone, extraction, orthogonal design
