Problems solved by technology

[0004] In my country, due to the late start of the modified starch industry compared with developed countries, the development of soluble starch began at the beginning of this century due to the limitation of technical level and product variety, but the soluble starch developed by most research units has high reduc

Embodiment Construction

[0028] In the stainless steel enzymatic hydrolysis kettle, add 100 kg of starch, 120 kg to make 40% starch milk, start stirring, add 3 kg of α-amylase, heat up to 50 ° C, react for 30 minutes, and centrifuge to remove the liquid. Then it was made into 40% starch milk, then added to the stainless steel reaction kettle, and 15 liters of 31% hydrochloric acid solution was added (it was formulated into a hydrochloric acid solution with a concentration of 5.96%), acidified at 40°C for 2 hours, and then heated to 50°C , add dropwise the remaining 15 liters of hydrochloric acid solution (it is formulated into a hydrochloric acid solution with a concentration of 5.96%) for acidification, the jacket is heated by hot water, the temperature of the material is maintained at 50 ° C, and it is incubated for 2 hours, and then 10% hydroxide is added Neutralize the remaining acid with sodium, add 200 kg of water to wash twice, centrifuge and deliquify, send the centrifuged material to a vacuum ...

Abstract

The invention relates to the field of starch production, in particular to a method for preparing soluble starch. The method is characterized in that a bio-enzyme enzymolysis secondary acidification technical route is adopted to produce the soluble starch and comprises the following steps of: adding alpha-amylase to 40 percent corn starch milk; degrading with bio-enzyme and then removing liquid; then dispersing chain scission corn starch into an aqueous solution; carrying out secondary acid denaturation; and neutralizing, removing liquid and dynamically drying to obtain a finished product.

Description

technical field [0001] The invention relates to the field of starch production, in particular to a method for producing soluble starch. Background technique [0002] Soluble starch is white or off-white powder, which is modified corn starch. Non-toxic and harmless, good solubility in hot water, stable chemical properties, low reducibility, strong adsorption, good fluidity, and no moisture absorption. [0003] In foreign countries, the acid denaturation technology of biological enzymatic hydrolysis and water solvent method is the most advanced soluble starch production technology first developed in the United States at the beginning of this century. This technology is a fundamental challenge to the traditional one-time acid denaturation technology. With the corn starch deep processing industry With the rapid development and increasingly fierce technical competition, this technology has become the most popular and promising soluble starch production technology in the world. ...
