Abstract

The present invention discloses an antioxidant additive for grape skins and a preparation method thereof. The antioxidant additive for the grape skins comprises the following components in parts by weight: 20-30 parts by weight of a grape skin extract, 3-5 parts by weight of calcium carbonate, 0.01-0.02 part by weight of selenium, 0.1-0.2 part by weight of vitamin A, 0.1-0.5 part by weight of vitamin E, 3-8 parts by weight of vitamin C, 0.1-0.2 part by weight of lucid ganoderma powder, and 0.01-0.02 part by weight of cordyceps sinensis powder. The antioxidant additive is prepared from natural raw materials, high in nutritional value, and free of toxic and side-effect, can prevent coagulation, lower blood lipids, strengthen immune cells and prevent tumors, has very good antioxidant effects, and is wide in application ranges.

Description

technical field [0001] The invention belongs to the technical field of food additives, and in particular relates to an antioxidant addition to grape skin 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. bodily damage. Artificial chemical food antioxidant additives refer to those made 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 may even endanger human health. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a grape skin a...
