Abstract

The invention discloses green environment-friendly modified starch and a preparation method thereof. The green environment-friendly modified starch comprises the following raw materials by mass percentage: 8-12% of original starch, 30-40% of esterified starch, 5-8% of goat milk protein, 3-6% of sucrose ester, 5-10% of monoglyceride, 2-4% of methyl benzoate, 5-8% of selenium-enriched yeast, 6-8% ofproanthocyanidins, and 4-6% of carrageenan. The modified starch prepared by the method of the invention has high viscosity and good elasticity of paste liquid, and can improve the health of the food.

Description

technical field [0001] The invention relates to the field of modified starch, in particular to a green and environment-friendly modified starch and a preparation method thereof. Background technique [0002] Starch is an inexpensive natural renewable resource with good biodegradability. Acetate starch, also known as acetylated starch, is a modified starch obtained by reacting the hydroxyl groups in starch macromolecules directly with acetic acid or indirectly with acetic acid derivatives under certain conditions. Acetate starch is an important variety of modified starch. Compared with native starch, it has the advantages of low gelatinization temperature, high viscosity, good transparency, weak retrogradation, soft and bright film, and is not easy to age. Stability and good water retention properties. At present, acetate modified starch has been widely used in food, textile, paper and other industrial fields. In recent years, the excessive pursuit of high yield and high y...
