Abstract

The invention discloses a starch octenyl succinate anhydride preparation process, which includes: preparing starch milk by water and starch, circulating the starch milk between a pipeline and a reactor by pumping, applying an ultrasonic field to the material on the pipeline for material circulation by a forceps type ultrasonic generator with the ultrasonic frequency ranging from 15-25KHz and the ultrasonic strength ranging from 0.05W / cm3-0.20W / cm3, then regulating the pH(potential of hydrogen) value of the starch milk to be 8.0-9.0, controlling the temperature of the starch milk below 40 DEG C, adding a surfactant which takes 0.01%-1% of the dry basis weight of starch, mixing uniformly, then adding octenyl succinic anhydride into the mixture for reacting, and finally obtaining the starch octenyl succinate anhydride through neutralizing, washing and drying after finishing reaction. The preparation process has the advantages that reaction efficiency of octenyl succinate anhydride is increased greatly, reaction time is shortened remarkably and the like, and has good market popularization prospects.

Description

technical field [0001] The invention relates to the field of hydrophobic modification of starch and its deep processing, in particular to a preparation method of starch octenyl succinate. Background technique [0002] Starch is modified by esterification with octenyl succinic anhydride, and hydrophilic and hydrophobic groups are simultaneously introduced into the starch molecule to obtain a very important food emulsifying thickener—starch octenyl succinate. This product has the characteristics of natural, safe, low calorie, emulsification and thickening, etc. It can replace gum arabic, and has a wide range of applications in high value-added fields such as emulsified flavors and fragrances, microcapsule wall materials, soft drinks, and yogurt. [0003] Starch alkenyl succinate was initially successfully developed by Caldwell and Wurzburg in the United States and applied for a patent in 1953. In 1972, the United States listed octenyl succinic acid starch ester in the food ad...
