Abstract


Modified Starch research and production has been rapid development.Modified starch industry has become a good market prospect and development of future industries. Described in this article Octenylsuccinate starch ester is a very important pro-fat starch..Bacause of good performance of its products and high added value,it can be widely used in micro-capsules,food and pharmaceutical industries as emulsifiers, stabilizers,thickeners.Now our country has approved such products can be used for food there is:Octenylsuccinate starch and sodium starch Octenylsuccinate two varieties of aluminum.Currently relies mainly on imports of such products,our development and production of such products is our country in order to fill the gaps in this area,in the domestic add these new varieties of food additives.Of different reaction system than to find a suitable dispersed phase,and on this basis to explore a different catalysts on Octenylsuccinate starch acetate degree of substitution impact.By octenyl succinic anhydride and sodium content in different concentrations and their mutual interaction,found the degree of substitution and the correlation between reactant.Starch impurities through research,discovered the effects of impurities on the reaction to overcome the technology in the production process difficult to solve the modified starch with low degree of substitution problems,improve the Octenylsuccinate starch ester product quality and reduce its production cost.An experimental study in the above basis,through the comparison of different experimental conditions,finally found the most suitable conditions for production technology.Significantly improve product performance,greatly reduces the quality of products,a strong enhance the product competitiveness.
