Abstract

The invention discloses a radix sophorae flavescentis antioxidant additive and a preparation method thereof. The radix sophorae flavescentis antioxidant additive disclosed by the invention comprises the following components: a radix sophorae flavescentis extract, lotus plumule powder, grape seed powder, sodium citrate, vitamin A, vitamin E, vitamin C, and vitamin D. Raw materials of the radix sophorae flavescentis antioxidant additive are natural. The prepared radix sophorae flavescentis antioxidant additive is high in nutritional values, free of toxic and side effects, capable of resisting clotting, reducing blood lipid, enhancing immunological cells and resisting tumors, very good in anti-oxidation effects, and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of food additives, and particularly relates to an antioxidative addition of Sophora flavescens and a preparation method thereof. Background technique [0002] Existing food antioxidant additives mainly include chemical food antioxidant additives and natural food antioxidant additives. Among them, chemical food antioxidant additives have good effects, but there are disadvantages such as toxic and side effects to varying degrees, and long-term use or excessive consumption are harmful. damage to the body. Artificial chemical food antioxidant additives refer to those prepared by artificial chemical synthesis. At the same time, a large number of research reports point out that almost all chemical food antioxidant additives cannot provide nutrients to the human body, and some chemical food antioxidant additives can even harm human health. SUMMARY OF THE INVENTION [0003] The purpose of the present invention i...
