Processing method of resistant starch containing food raw materials

Abstract

The present invention discloses a processing method of resistant starch containing food raw materials. By studying quality safety controlling means and matching technologies and optimizing an radiation processing technology, the method conducts a strict fully automated control of material selection, and irradiation doses, irradiation time and an irradiation box moving mode during the irradiation process, improves processing efficiency and utilization rate of radioactive sources, reduces the economic costs and the use of preservatives, significantly reduces the microbial content of the products, and solves the problems of air producing and inflatable bags of products caused by anaerobic bacteria, so that the product quality is improved and people's body health is ensured.

Description

technical field

[0001] The invention belongs to the field of food processing, and in particular relates to a processing method for food raw materials containing resistant starch. Background technique

[0002] Resistant starch, also known as enzyme-resistant starch and indigestible starch, cannot be enzymatically hydrolyzed in the small intestine, but can undergo fermentation reactions with volatile fatty acids in the human gastrointestinal tract and colon. Resistant starch exists in some natural foods, such as potatoes, bananas, rice, etc., all contain resistant starch, especially high-amylose corn starch contains up to 60% resistant starch. Compared with other starches, this kind of starch is difficult to degrade, digests slowly in the body, absorbs and enters the blood more slowly. Its properties are similar to soluble fiber, and it has a certain slimming effect. In recent years, it has been favored by beauty lovers. In the current manufacturing process of starch food,...
