Preparation method of selenium-rich high protein active peptide additive

Abstract

The invention discloses a preparation method of a selenium-rich high protein active peptide additive. The method includes: subjecting feed grade sodium selenite and a yeast dry powder solution to fermentation reaction to prepare organic liquid selenium yeast, conducting mixed fermentation on the organic selenium yeast, fermented chicken manure, feather meal, meat and bone meal, eggshell, an enzymepreparation, molasses and the like, controlling the water content of the obtained fermented material at about 70% and breeding housefly larvae for a period of time, then getting the housefly larvae out and performing washing, then subjecting the washed housefly larvae and liquid selenium yeast to mixed fermentation for 24h to obtain a selenium-rich high protein active peptide extracted liquid, using feed grade calcium powder for adsorption, employing a heat pump for drying, and conducting milling to 300-800 mesh, thus obtaining the selenium-rich high protein active peptide additive raw material. The selenium-rich high protein active peptide additive prepared by the method provided by the invention has the advantages of: safety, no residue and no pollution, is a green feed and fertilizer additive capable of replacing antibiotics and pesticides, and has broad application prospects.

Description

technical field [0001] The invention relates to a selenium-enriched product, in particular to the preparation of a selenium-enriched high-protein active peptide additive, belonging to the field of selenium-enriched products. Background technique [0002] In recent years, selenium has become a research hotspot in various disciplines such as trace element science, nutrition and immunology. Selenium has the characteristics of anti-oxidation, delaying aging, inhibiting tumors, removing the accumulation of heavy metals in the body, and detoxifying heavy metals. Moreover, selenium is also a natural antidote for some heavy metal elements. Compared with inorganic selenium, organic selenium has the characteristics of high absorption rate, strong biological activity, low toxicity and low environmental pollution, and has become a focus of current selenium research. It is advocated internationally to replace inorganic selenium with organic selenium as a nutritional supplement of seleni...
