Problems solved by technology

[0003] However, SOD enzymes widely exist in the animal and plant kingdoms in the prior art, and they are not resistant to high temperatures (above 40° C.), and are easily destroyed by the acid-base of the human gastrointestinal tract. Moreover, the SOD content is also low, and the consumption of people is uncontrollable. Unquantifiable

Abstract

The invention provides a method for extracting an SOD (Superoxide Dismutase) refined enzyme from SOD enriched plants (triticale, rice oil bran powder, black garlic, hippophae rhamnoides, rosa roxburghii, pinus tabuliformis carrire and pinus tabuliformis carrire) after biological fermentation. The method comprises the following steps of selecting SOD enriched raw materials, mixing the SOD enriched raw materials according to a proportion, and fermenting an obtained mixture for 3 days at 10 to 40 DEG C; carrying out wet grinding, collecting pulp, centrifuging the pulp at a high speed, breaking cell walls, and filtering by a molecular sieve, so as to subsequently obtain an SOD crude enzyme; heating the SOD crude enzyme, then putting the heated SOD crude enzyme for a period of time, and then filtering the SOD crude enzyme by using the molecular sieve, and treating filtrate by using a low-temperature spray freeze drying method; collecting dry powder, so as to obtain the SOD refined enzyme. The SOD refined enzyme extracted by the method is an active enzyme which can be resistant to a high temperature; the enzyme activity is not destroyed; the SOD enzyme activity is maximized; the maximization of the absorption and the utilization of a body on the SOD refined enzyme is realized.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for extracting SOD essence enzyme from SOD-rich plants (plants such as triticale and rice oil bran powder) after biological fermentation. Background technique [0002] SOD is the abbreviation of Super Oxide Dismutase. The Chinese name is superoxide dismutase. It is an important antioxidant enzyme in organisms and is widely distributed in various organisms, such as animals, plants, and microorganisms. SOD has special physiological activity and is the primary substance for scavenging free radicals in organisms. The level of SOD in the living body means an intuitive indicator of aging and death; it has been confirmed that there are as many as 60 kinds of diseases caused by oxygen free radicals. It can resist and block the damage to cells caused by oxygen free radicals, repair damaged cells in time, and restore the damage to cells caused by free radicals. Due to th...
