Abstract
The gel characteristics of phosphoric ester in sweet potato starch were studied and the effects of concentration,pH,electrolyte and non-electrolyte on gel strength of phosphoric ester in sweet potato starch were discussed.The gel properties of phosphoric ester in sweet potato starch were revealled.In addition,the structure of phosphoric ester in sweet potato starch was analyzed by the means of FTIR spectra and X-ray diffraction,which could provide a theoretical basis for using phosphoric ester in sweet potato starch to substitute or partly substitute the gel of other types with a high price in the food industry.
