Abstract

The invention belongs to the modified field of starch, relating to a starch suspension stabilizer and a preparation method thereof. Defects that the native starch cannot be dissolved in cold water and the like limit the application thereof in the industry; and the modification of the starch mainly adopts a chemical means at present, and the method can improve the dissolubility of the starch, but has complex operation and high modification cost. The invention provides a method which adopts the physical dispersing principle to improve the dispersing level of the starch in the cold water and thestarch suspension stabilizer which is prepared by adopting cellulose derivative as main raw materials through proper weight matching. In the invention, the obtained stabilizer can greatly improve thedispersing level of the starch in the cold water, is stable and reliable, and can lead the starch in the cold water to disperse for more than half an hour, thus greatly expanding the application scope of the starch.

Description

Technical field: [0001] The invention belongs to the field of starch modification, in particular to a starch suspension stabilizer and a preparation method thereof. Background technique: [0002] Starch is widely distributed in nature and is a storage form of plant nutrients. It mainly exists in the roots, stems, leaves, fruits and pollen of higher plants. It is one of the main sources of energy for humans and animals. [0003] Starch is a renewable and biodegradable biopolymer compound, which is a typical and ideal renewable natural raw material. In the field of chemical industry, alcohol, acetic acid, lactic acid, isopropanol, n-butanol, and many ketones, acids, ethers, esters and other compounds can be produced through starch fermentation, and can also be used as plastic fillers, etc.; in the field of food industry, it is a manufacturing The main raw material of starch sugar and an important source of food additives; in the field of light industry, it can be used as a re...
