Selenium-enriched rice bran enzyme deactivation stabilization treatment method

Abstract

The invention belongs to the technical field of agricultural and sideline product processing, and particularly discloses a selenium-rich rice bran enzyme deactivation stabilizing treatment method, which comprises the following steps: putting rice bran into a high-temperature-resistant plastic bag, semi-sealing the plastic bag, and reserving an air outlet hole of 1-10 cm; flatly putting the baggedrice bran into microwave equipment, flattening the rice bran, starting the microwave equipment, and carrying out enzyme deactivation treatment through microwave heating; and then sending the rice branout of microwave equipment, sealing the plastic bag while the rice bran is hot, and finally sending the bagged rice bran into a low-temperature warehouse for cooling. According to the invention, a microwave rapid heating mode and a damp-heat treatment mode are combined, a semi-sealed plastic bag mode is innovatively adopted, damp-heat steam generated by microwave heating of rice bran is ingeniously utilized, and the technical defects of low heat efficiency utilization, non-uniform material temperature and non-uniform and non-stable enzyme deactivation effect of traditional microwave treatmentof rice bran are overcome; the invention provides the rice bran enzyme deactivation stabilization method which is simple in process, high in production efficiency, small in equipment investment and suitable for medium millet factories.

Description

Technical field [0001] The present invention relates to the field of agricultural and sideline product processing techniques, and in particular, there is a method of stabilizing the enzyme-enzyme stabilization. Background technique [0002] In the process of selenium-enriched rice, rice bran and gravel become the largest processed by-product, accounting for 15% to 20% of rice machining. Rice bran is one of the by-products produced in the process of rice milling. In recent years, they have received extensive attention due to their potential health benefits. The rice bran contains 14 ~ 24% fat, 12 ~ 18% protein, is a high-quality resource producing rice bran oil and rice bran protein. Rice bran also contains polyphenols, phytosterols, tamperdinols, gamma-γ-γ, B-vitamins, minerals, etc., can serve as a valuable resource for healthy diet. Rice bran is rich in fat, which contains about 42% of oleic acid, 38% linoleic acid, while rice bran contains a strong fat hydrolase and fatty oxid...

Problems solved by technology

[0004] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a method for stabilizing selenium-enriched rice bran to inactivate enzymes. The method of bagging cleverly utilizes the hot and humid steam produced by microwave heating of rice bran, which overcomes the technical defects of low thermal efficiency, uneven material temperature, and uneven and stable enzyme killing effect of traditional microwave treatment of rice bran, and provides a simple process, high production efficiency, and low equipment investment. Small, suitable for rice bran enzyme stabilization method for medium and small millet plants
