Abstract

The invention provides a preparation method and applications of octenyl succinate distarch phosphate. The preparation method comprises the following steps: using potato starch and sodium trimetaphosphate (STMP) to perform crosslinking reaction, and then adding octenyl succinic anhydride which is diluted with absolute alcohol to perform esterification reaction. The octenyl succinate distarch phosphate prepared by the method has the advantages that the product has high viscosity and stability, excellent free fluidity and hydrophobicity, good emulsion stability and high temperature resistance, has acid resistance, alkali resistance and saline environment resistance and also has high freeze-thaw stability; and the special properties of potato starch can be maintained.

Description

technical field [0001] The present application relates to a preparation method of octenyl succinic acid distarch phosphate, the octenyl succinic acid distarch phosphate prepared according to the method and its application. Background technique [0002] Octenyl succinic acid starch ester (OSA-starch) is a kind of fine chemical with excellent performance, and also a kind of modified starch. It was successfully developed by Caldwell and Wurzburg in the United States at first, and applied for a patent in 1953. The product was included in the Chemical Handbook of Food Products, but China only approved it as a food additive in 1997, and approved its edible scope in 2001. Due to the lack of octenyl succinic anhydride (Octenyl Succinic Anhydride referred to as OSA), the application lags far behind the United States, Japan, and European countries. Starch octenyl succinate is a starch modification obtained by esterification of octenyl succinic anhydride and starch [Research Progress ...
