Problems solved by technology

For the starch octenyl succinate prepared from native starch, because it is insoluble in water, it can be washed and filtered many times to meet the quality requirements; if water-soluble starch octenyl succinate is to be prepared, it is necessary to wash The standard octenyl succinic acid raw starch ester is hydrolyzed again, which will cause the partial hydrolysis of octenyl succinic acid ester at the same time, so that the degree of substitution will decrease and the residual amount of octenyl succinic acid will increase; for hydrolysis The final water-soluble starch, according to the existing various processes to prepare starch octenyl succinate, can not effectively remove the unreacted octenyl succinic acid, resulting in a large amount of residual octenyl succinic acid exceeding the standard

Abstract

The invention discloses a preparation method of an octenyl succinic acid water-soluble starch ester. The method comprises the following steps: grinding dry ore materials, screening and evenly mixing with octenyl succinic anhydride; then dripping a water-soluble starch solution into a mixture of the ore materials and the octenyl succinic anhydride and reacting under an alkaline condition; and finally, regulating a pH value to reach acidity, centrifuging after oscillating, taking out a supernatant and drying, thereby obtaining the octenyl succinic acid ester of the water-soluble starch. The method has the advantages that the octenyl succinic acid water-soluble starch ester with high substitution efficiency and low octenyl succinic acid residue quantity can be prepared by directly utilizing the water-soluble starch.

Description

technical field [0001] The invention relates to the technical field of food chemistry, in particular to a preparation method of octenyl succinic acid water-soluble starch ester. Background technique [0002] Starch octenyl succinate generally exists in the form of sodium octenyl succinate (Starch Sodium Octenyl Succinates, SSOS), which is a highly safe emulsifying thickener. The Food and Drug Administration (FDA) is included in the category of food additives in the United States, and it is currently the only starch octenyl succinate product that is allowed to be used as a food additive by the FDA. [0003] Starch octenyl succinate has been approved for use by major countries in the world including China, and its quality index is that when producing food-grade starch octenyl succinate, the maximum allowable treatment amount of octenyl succinic anhydride is 3% , the degree of substitution is not more than 0.02, and the residual amount of octenylsuccinic acid is less than 0.3%...
