Glycine nano-selenium and preparation method thereof

Abstract

The invention discloses glycine nano-selenium and a preparation method thereof. 0.9 weight portion of selenium and 85 to 95 weight portions of glycine form granular nano-selenium, the particle size of the nano-selenium is between 20 and 80 nm, and the average particle size is 60nm. The preparation method thereof comprises the following steps that: 2 to 3 weight portions of sodium selenite is dissolved into 15 to 25 weight portions of water to obtain a sodium selenite solution at normal temperature and normal pressure, 0.5 to 1.5 weight portions of polyvinylpyrrolidone (PVP) surfactant is added into the solution to form an emulsion, then 3 to 6 weight portions of vitamin C is added into the emulsion, the vitamin C and the emulsion react for 20 to 40 minutes at normal temperature, a reaction liquid is absorbed by 80 to 120 weight portions of glycine, and finally the obtained product is dried, crushed, sieved and packaged. The invention solves the problems that red liquid nano-selenium is not favorable for packaging and transportation, and adopts the glycine as an adsorbent and a stabilizing agent of nano-selenium to ensure that the liquid nano-selenium forms the solid glycine nano-selenium; and after the glycine nano-selenium is prepared into a nanometer additive, the nanometer additive is easy to digest and absorb, can ensure the rapid growth of beasts and birds, and can also greatly reduce the using amount, thereby reducing raising technology and improving economical benefit.

Description

technical field [0001] The invention relates to a glycine nano-selenium used in animal feed to provide selenium nutrients for animals and a preparation method thereof, belonging to a nutritional feed additive. Background technique [0002] The research background of nano-selenium is: organic selenium chemistry has developed extremely rapidly in the past 20 years, new organic selenium reagents play an important role in organic synthetic chemistry, and are widely used in the synthesis of natural products; at the same time, the discovery of organic selenium antineoplastic drugs greatly It enriches the research and application content of organic selenium chemistry. However, organic selenium is also highly toxic, and its preparation is tedious and time-consuming. With the development of modern science and technology and the interdisciplinary application of multiple disciplines, selenium preparations have entered a new stage - the stage of nano red element selenium. For a long t...
