And thirdly, coating the biomass processed in the first step with cyclodextrin, immersing the biomass in melted solid salt in a crucible, preserving the heat for 0.25-2h, cooling to room temperature, taking out the product, washing, centrifuging, and freeze-drying in vacuum to obtain the blueberry sesame powder antioxidant additive.

2. The preparation method of the blueberry sesame powder antioxidant additive as claimed in claim 1, wherein the biomass weight ratio in the first step is 10-20 parts of blueberry powder, 0.3-0.5 part of sesame powder, 0.2-0.5 part of sea cucumber powder and 0.2-0.5 part of ginseng powder.

3. the preparation method of the blueberry sesame powder antioxidant additive as claimed in claim 1, wherein the metal salt solution in the first step is one or more aqueous solutions of nitrates, sulfates and chlorides of Fe, and the concentration of the metal salt solution is 0.3-3 mol/L.

4. The preparation method of the blueberry sesame powder antioxidant additive as claimed in claim 1, wherein the biomass and the metal salt solution are mixed and soaked in the first step, the process comprises the steps of placing the crushed biomass in a container, vacuumizing, reducing the vacuum degree to 0.1-0.3Mpa, adding the metal salt solution, soaking for 15-180min, and repeating for 2-5 times until the mass of the dried biomass is increased by 0.1-15%.

5. The preparation method of the blueberry sesame powder antioxidant additive as claimed in claim 1, wherein the solid salt in the second step is NaCl.

Technical Field

the invention belongs to the technical field of food additives, and particularly relates to a preparation method of a blueberry sesame powder antioxidant additive.

Background

The existing food antioxidant additives mainly comprise two categories of chemical food antioxidant additives and natural food antioxidant additives, wherein the chemical food antioxidant additives have good effects, but have the defects of different degrees of toxic and side effects and the like, and cause damage to bodies after long-term use or excessive eating. The antioxidant additive for artificial chemical food is prepared by artificial chemical synthesis method. Meanwhile, a great deal of research reports indicate that almost all chemical food antioxidant additives cannot provide nutrients to human bodies, and some chemical food antioxidant additives even harm human health.

Disclosure of Invention

the invention aims to overcome the defects of the prior art and provides a blueberry sesame powder antioxidant additive.

the invention also aims to provide a preparation method of the blueberry sesame powder antioxidant additive.

the technical scheme of the invention is as follows:

1. A preparation method of a blueberry sesame powder antioxidant additive comprises the following steps:

Drying and crushing biomass, mixing and soaking the crushed biomass and a metal salt solution, centrifuging, freezing and drying in vacuum, and repeating for 2-5 times until the mass of the dried biomass is increased by 0.1-15%;

Secondly, solid salt is put into the crucible, inert gas nitrogen is continuously introduced, and the crucible is heated to the temperature of 450-900 ℃ to melt the solid salt in the crucible;

And thirdly, coating the biomass processed in the first step with cyclodextrin, immersing the biomass in melted solid salt in a crucible, preserving the heat for 0.25-2h, cooling to room temperature, taking out the product, washing, centrifuging, and freeze-drying in vacuum to obtain the blueberry sesame powder antioxidant additive.

2. The preparation method of the blueberry sesame powder antioxidant additive comprises the following steps of 10-20 parts of blueberry powder, 0.3-0.5 part of sesame powder, 0.2-0.5 part of sea cucumber powder and 0.2-0.5 part of ginseng powder by weight.

3. The preparation method of the blueberry sesame powder antioxidant additive comprises the step I, wherein the metal salt solution is one or more aqueous solutions of nitrates, sulfates and chlorides of Fe, and the concentration of the metal salt solution is 0.3-3 mol/L.

4. The preparation method of the blueberry sesame powder antioxidant additive comprises the steps of mixing and soaking the biomass and the metal salt solution in the first step, placing the crushed biomass in a container, vacuumizing, reducing the pressure to 0.1-0.3Mpa, adding the metal salt solution, soaking for 15-180min, and repeating for 2-5 times until the mass of the dried biomass is increased by 0.1-15%.

5. In the preparation method of the blueberry sesame powder antioxidant additive, the solid salt in the second step is NaCl.

the invention has the beneficial effects that:
