Method for producing harmless selenium-rich black earth pork by utilizing selenium-rich astragalus sinicus secondary conversion technology

Abstract

The invention relates to a method for producing harmless selenium-rich black earth pork by utilizing a selenium-rich astragalus sinicus secondary conversion technology, which is characterized by comprising the following steps of: planting the astragalus sinicus, spraying on leaves by utilizing a prepared selenium-rich nutrient solution; drying in the sun, storing and pulverizing the selenium-rich astragalus sinicus, mixing with the pulverized high quality corn, wheat bran, bean pulp and mineral matter powder to prepare selenium-rich compound feeds; feeding according to different pig ages; and selling a pig growing to about 80kg to a target place for butchering, and processing into the harmless selenium-rich black earth pork which is packaged by a vacuum film. The method for producing harmless selenium-rich black earth pork by utilizing the selenium-rich astragalus sinicus secondary conversion technology has the advantages that the selenium bioavailability is high, the nutrition is safe, the meat quality is excellent, the capability against disease of the pig is strong, the residue of bacteriophage is low, the compound feed is high quality natural farm crops without pesticide residue, and the products subjected to inspection completely satisfy the harmless food standard.

Description

Technical field: [0001] The invention relates to a method for cultivating pollution-free selenium-enriched black earth pork by processing selenium-enriched plants into feed through secondary biological transformation technology. Background technique: [0002] In 1973, the World Health Organization (WHO) announced that selenium is an essential trace element in animal life. In 1994, my country allowed the addition of selenium in food as a food nutrition fortifier and promulgated the national standard GB14880-1994. In 2003, the US Food and Drug Administration (FDA) Approves selenium as a cancer suppressor and allows selenium supplements to label selenium's cancer suppressor properties. In recent years, people have increasingly realized that selenium plays an important role in maintaining human life activities. Selenium is an important part of glutathione peroxidase, and it is also an antioxidant, which can eliminate excessive free substances in the body. Selenium supplementatio...

Problems solved by technology

[0003] The selenium supplement products sold in the domestic market and their production methods mainly include: 1) inorganic selenium tablets, capsules or oral liquids directly processed with inorganic salts and sodium nitrite as raw materials. These selenium products are poorly absorbed by the human body and bioavailable. 2) Tablets, capsules or suspoemulsions processed using selenium yeast produced by the fermentation technology of agricultural raw materials as raw materials, such products need to add auxiliary agents, auxiliary materials, stabilizers, preservatives, flavoring agents, etc. in the production process chemical composition
