Method for preparing antioxidative reishi shell-broken spore powder and product

Abstract

The invention discloses a method for preparing antioxidative reishi shell-broken spore powder. The method comprises the following steps of: fully mixing the reishi shell-broken spore powder with a chitosan vinegar colloid solution to fully absorb the reishi shell-broken spore powder on the chitosan vinegar colloid solution; drying the reishi shell-broken spore powder absorbed on the chitosan vinegar colloid solution to obtain the antioxidative reishi shell-broken spore powder; and obtaining the chitosan vinegar colloid solution by fully dissolving 2-5 parts by weight of chitosan and 100 parts by weight of vinegar. By the method, a layer of chitosan protective film is attached to the surface of the reishi shell-broken spore powder, and the contact between the ganoderma lucidum spore powder and external environment air is effectively isolated, so that high antioxidant ability is achieved, and the preservation period is prolonged; and moreover, by the method, the rise of an peroxidation value of the product can be effectively prevented, the health hidden troubles which can be possibly generated is avoided, and the quality of the product is improved.

Description

technical field [0001] The invention relates to a preparation method and product of anti-oxidation broken ganoderma lucidum spore powder, belonging to the technical field of functional food engineering. Background technique [0002] Ganoderma lucidum spore powder is the extremely tiny oval germ cells ejected from the gills of Ganoderma lucidum, that is, the seeds of Ganoderma lucidum during the growth and maturity stage. Only 1 kg of Ganoderma lucidum can be collected to obtain 1 kg of pure spore powder. It is determined that Ganoderma lucidum spore powder contains active substances such as Ganoderma lucidum polysaccharides, Ganoderma lucidum polypeptides, triterpenoids, amino acids, proteins, fatty acids, trace elements, etc., especially fat-soluble substances can be as high as 20%, of which mainly unsaturated fatty acids. The size of Ganoderma lucidum spores is only 5-10 microns, and an oval-shaped object can be seen under a microscope. It is a living organism and is surr...

Problems solved by technology

However, the nutritionally active substances in the spores of the broken Ganoderma lucidum spore powder are directly exposed to the external environment, and due to the presence of oxygen in the outside air, the nutritionally active substances in these spores are easily oxidized and deteriorated, and lose their efficacy. The problem of preservation; especially the unsaturated fatty acid in Ganoderma lucidum spore oil will appear rancid after being oxidized, and the peroxide value will rise sharply, which may bring health hazards to the user's body
