Embodiment 1

[0029] A preparation for high-efficiency preservation of wheat germ, the preparation includes the use of small molecule organic matter containing active H for preservation.

[0030] The small molecular organic substances include but are not limited to at least one of the following components: ethanol, ether, methanol, ammonia and formaldehyde. The small molecular organic matter can be adsorbed on adsorbents such as fiber sheets and organic silicon, or mixed with esters and packaged in air-permeable bags or added directly.

[0031] The weight ratio of the small molecule organic matter to the wheat germ is: 1:(50-200), specifically 1:50, 1:80, 1:100, 1:120, 1:150, 1:200, etc., such as 10g of ethanol is added to every kilogram of wheat germ, and the ethanol can be 50% to 100% ethanol, such as 75% ethanol.

[0032] In this embodiment, the preservation method is: directly add the small molecular organic matter into the wheat germ for sealing packaging, or pack the small molecular ...

Embodiment 2

[0034] A preparation for high-efficiency preservation of wheat germ, the preparation includes an auxiliary preservative and a small molecular organic compound containing active H, the small molecular organic compound is the organic compound described in Example 1, and will not be repeated here.

[0035] Described auxiliary preservative includes iron powder and / or activated carbon etc., preferably wherein one or two just can, as only adopt iron powder and adopt activated carbon etc., the mass ratio of described auxiliary preservative and small molecule organic matter is: 1:(1 ~15), such as: 1:1, 1:5, 1:10, 1:15, etc.

[0036] During specific use, the auxiliary preservative is independently packaged in air-permeable packaging to prevent contamination of wheat germ. For example, packaging of preservatives or moisture-absorbing agents in bagged foods can make gas molecules pass.

Embodiment 3

[0038] A preservation component for high-efficiency preservation of wheat germ, the preservation component comprises a preparation for high-efficiency preservation of wheat germ and a package for packaging wheat germ. The formulation is the formulation described in Example 1 and Example 2.

[0039] The packaging preferably has high-density and high-barrier packaging, that is, packaging made of high-density and high-barrier materials, such as aluminum foil composite films, nylon composite films or synthetic resin composite films. Plastic, aluminum, iron, glass or ceramics and other high-density and high-barrier materials are usually made into packaging boxes or packaging bottles or packaging barrels. Cooperating with the above-mentioned preparation, the effect is remarkable, and the wheat germ can be preserved for a long time to keep it active.

Abstract

The invention relates to a preservative, a preservative assembly and a preservation method used for highly-efficient wheat germ preservation. The preservation method comprises the following steps: S1,containing wheat germ in a package, or containing wheat germ firstly in a ventilated bag and then in a package; S2, adding a preparation capable of efficiently preserving wheat germ into the package,wherein the preparation comprises small-molecule organic matters with high activity; and S3, sealing the package. The preservation method is capable of greatly prolonging shelf life of wheat germ soas to achieve very convenient storage, transport and the like of wheat germ.

Description

technical field [0001] The invention relates to the technical fields of biology and food, in particular to a preservative, a preservation component and a preservation method for efficient preservation of wheat germ. Background technique [0002] Wheat germ is the vital point of wheat grain and the part with the highest nutritional value in wheat grain. In modern flour processing, because the germ is very active and easily oxidized and deteriorated, the shelf life of flour will be shortened, so the wheat germ is separated and removed during flour processing. my country's annual reserves of wheat germ that can be used for development reach 4.2 billion kilograms. About 80% of it is mixed with bran and used as feed. Wheat germ is rich in protein, minerals, vitamins, dietary fiber and fat. It is the life point of wheat and the concentration of various nutrients needed by wheat for life. The protein content of wheat germ even exceeds milk powder. Nutritionists call wheat germ ...
