Open publisher page 0 citations

Abstract

The extraction technology was studied in this paper, and water extraction was used to extract water-soluble glycoprotein(WSGP).WSGP was extracted by water from fresh sweet potato.It was precipitated by Ethanol absolute or(NH4)2SO4, then dialysis and Vacuum drying.The technology was chosen by the experiments of single factor and orthogonal.The main factors from more important to less in affecting the extraction rate are as follows:raw material and water ratio, extracting time, extracting times.The result showed that the best technology are that raw material and water ratio is 1:15,extracting time is 1 h and extracting times is 3.
