Preparation method of five-cereal powder rich in SOD

Abstract

The invention discloses a preparation method of five-cereal powder rich in SOD. The preparation method comprises the following steps of (1) soaking cereals with the SOD content of more than or equal to 18 U / mg in a potassium permanganate solution with the concentration of 0.1%-0.6% for 5-10 minutes, and conducting repeated cleaning with clean water for 3-4 times in a spraying manner; (2) stirringand drying the cereals completely cleaned in the step (1) at 40-50 DEG C under a ventilation condition until the moisture content of the cereals is 5%-10%; (3) circularly cooling the cereals dried inthe step (2) by adopting refrigerating fluid; (4) stirring the cereals cooled in the step (3) for 20-50 minutes in a sealed and ozone environment while circular cooling by the refrigerating fluid is carried out; and (5) carrying out wall-breaking crushing on the cereals subjected to ozone sterilization in the step (4) while circulating cooling by the refrigerating fluid is carried out until the granularity reaches 600-800 meshes, thereby obtaining the five-cereal powder rich in SOD. The method can well solve the problems of difficult extraction, difficult storage and difficult absorption of the SOD, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of SOD powder preparation, and in particular relates to a preparation method of SOD-rich grain flour. Background technique [0002] SOD, superoxide dismutase, is a protein rich in metal ions, widely distributed in various organisms. In 1938, American biomolecular expert Mike De, under the command of Frederick, successfully extracted SOD from the red blood cells of cattle for the first time. SOD has the characteristics of being afraid of high temperature and strong acid, and not easy to absorb. The essence of SOD is a kind of protease with high efficiency and specificity, which can effectively remove free radicals. It has no toxic and side effects and can be taken for a long time. With the increase of age, the free radical scavenging substance SOD in the human body is less and less, and the free radicals in the human body are constantly produced, and the scavenging function is out of balance, leading to vari...

Problems solved by technology

[0003] At present, there are three main ways to prepare SOD: one is to extract from animal tissue or blood, the SOD prepared by it is more expensive and has a short half-life in vivo, and the quality of raw materials is low. and safety are also doubtful; the second is the microbial fermentation method, the microorganisms are easily affected by the environment, so the activity and recovery rate of the SOD produced cannot be guaranteed; the third is the method in advance from the plant, which is easy to obtain materials and prepared SOD has the most economic value

Due to the extreme instability of SOD, the existing SOD preparation method, SOD is very easy to oxidize, degrade, denature and inactivate, there will be three major problems of SOD extraction, storage and absorption, and the preparation method of SOD is complicated, and the equipment investment in the process High cost, not suitable for large-scale industrial production
