Abstract
The invention relates to a preparation method of a raw starch enhanced modifying agent. Ammonium sulphate, sodium carbonate and sodium sulfite are respectively grinded by a ball mill, and the grinded powder particle passes a 100 mesh sieve; then the ammonium sulphate, the sodium carbonate and the sodium sulfite passes the 100 mesh sieve after being homogeneously blended at mass ratio of 1: (0.2-0.4): (0.1-0.3), and a hot air drying process is lastly carried out at the temperature of 120 DEG C. The raw starch enhanced modifying agent prepared by the preparation method of the invention can be directly added and used in the gelatinization process of the raw starch. Under the condition of 10 percent to 15 percent of gelatinization concentration of starch and 1.0 percent to 1.5 percent of agent usage (to completely dry starch), viscosity coefficient of starch gelatinization liquid can be greatly reduced, retrogradation of the starch gelatinization liquid can be greatly declined, and film forming ability of the gelatinization liquid and mechanical strength of the film can be obviously improved. The invention can be used for replacing conventional phosphate starch and oxidized starch, etc.
Description
Technical field
The present invention relates to a kind of preparation method who is used for the reinforced modifier of ative starch.
Background technology
Starch is a kind of reproducible natural high moleculer eompound, has a wide range of applications in industries such as food, weaving, papermaking, chemical industry, medicine, building.Without the primary starch of any modification because it in the defective that aspects such as gelatinization operation, the thermodynamic stability of sticking with paste liquid and film-forming properties exist, makes its using value be difficult to obtain due performance.
Summary of the invention
The object of the present invention is to provide a kind of preparation method that can improve the reinforced modifier that is used for ative starch of the gelatinization performance of ative starch, the Thermodynamically stable performance of sticking with paste liquid and film forming properties.
For achieving the above object, the technical solution used in the present invention is: at first adopt ball mill to carry out milled processed respectively ammonium persulphate and yellow soda ash, S-WAT, make the levigation particle cross 100 mesh sieves; Then by ammonium persulphate: yellow soda ash: S-WAT=1: (0.2～0.4): the mass ratio of (0.1～0.3) mixes the back with three kinds of materials and crosses 100 mesh sieves, gets final product 120 ℃ of following warm air dryings.
The original starch enhancement modifier that adopts preparation method of the present invention to obtain directly adds use in the gelatinization process of primary starch, in starch pasting concentration is that 10%-15%, additive amount are under the situation of 1.0%-1.5% (to over dry starch), the viscosity of starch pasting liquid is significantly reduced, the retrogradation of sticking with paste liquid declines to a great extent, and the film-forming properties and the film forming physical strength of sticking with paste liquid are able to remarkable improvement.Can substitute traditional phosphate ester starch and Sumstar 190 etc. fully uses.
