| titleOfInvention | Acid-heat degradation and enzymolysis preparation method of low-viscosity octenyl succinic anhydride modified starch |
| abstract | The invention discloses an acid-heat degradation and enzymolysis preparation method of low-viscosity octenyl succinic anhydride modified starch. The method comprises the following steps: raw starch is prepared into a slurry; alkaline liquid is added; octenyl succinic anhydride is fed; an esterification reaction is allowed; neutralization and liquid-removal are carried out; washing refining is carried out; a filter cake is prepared into a slurry; the pH value is regulated; an acid hydrolysis reaction is carried out; a continuous-ejection high-temperature acid-heat treatment is carried out; laminar-flow thermal insulation is carried out; cooling is carried out; a saturated calcium hydroxide solution is added; the mixture is stirred such that neutralization is carried out; pullulanase is added for carrying out debranching enzymolysis; active carbon is added; temperature is increased and decolorization is carried out; pressure filtration is carried out; the filtrate is concentrated under vacuum; fine filtration is carried out; spray drying is carried out; and cooling and packaging are carried out, such that a product is obtained. The product is suitable to be used as an emulsifier of foods and daily chemicals, or as a microencapsulation material. With the method, the low-viscosity water-soluble octenyl succinic anhydride modified starch product can be produced, and good economical benefit can be achieved. With a pullulanase debranching effect upon modified starch molecules, more products with linear or low-branch-degree molecular structures can be produced, such that product emulsifying and film-forming properties can be improved. |
