Abstract

The invention discloses stable water-soluble nano-selenium and a preparation method thereof. The preparation method comprises the steps of firstly, enabling tea leaves to be subjected to water extraction to obtain a tea extracting solution, and then mixing buckwheat rice, the tea extracting solution and a sodium selenite aqueous solution, serving as raw materials, to prepare a matrix; enabling the matrix to be inoculated with morchella strains, performing spawn running, collecting morchella hyphae, and performing ultrasonic crushing so as to obtain hypha powder; freezing and crushing the sodium selenite aqueous solution to obtain frozen particles I, and freezing and crushing the ascorbic acid aqueous solution to obtain frozen particles II; and finally, mixing the frozen particles I with the frozen particles II and the mycelium powder, performing freezing and grinding, and performing vacuum drying so as to obtain the product. The obtained nano-selenium can be stored at normal temperature, and is good in stability and water solubility.

Description

technical field [0001] The invention relates to a stable water-soluble nano-selenium and a preparation method thereof. The invention belongs to the technical field of nano selenium preparation. Background technique [0002] Selenium is an essential substance for the synthesis of selenium glutathione peroxidase, which can scavenge free radicals and improve immunity. It is an indispensable trace element for human and animal life activities. The existence of selenium in nature is divided into two types: inorganic selenium and organic selenium. Inorganic selenium generally refers to sodium selenite and sodium selenate, which are obtained from the by-products of metal mineral deposits. Organic selenium is combined with amino acids through biotransformation. It usually exists in the form of selenomethionine. However, inorganic selenium is highly toxic, and excess will cause harm to the human body. Excessive exposure during production and processing is also harmful to the human b...
