Abstract

The invention discloses a microwave-assisted method for synthesizing a beet alkali metal chelate, which comprises the following steps: respectively dissolving a betaine raw material and a metal salt in water, then transferring into a microwave high-pressure reaction kettle, carrying out microwave-assisted reaction to obtain a beet alkali metal chelate solution, and carrying out suction filtration, washing and drying to obtain the beet alkali metal chelate. The preparation method is simple to operate, the reaction is easy to control, and the production cost is low. The divalent metal betaine chelate is synthesized by taking a betaine raw material as an amino acid ligand, and the divalent metal betaine chelate is absorbed through an absorption channel of betaine, is better than a single metal salt absorption channel and can be fully and better absorbed by organisms, so that the mutual antagonism is reduced, the bioavailability of copper, zinc and manganese is improved, and the bioavailability of copper, zinc and manganese is improved. Meanwhile, microwave reaction is utilized in the synthesis method, so that the reaction speed and yield are greatly increased, and the application in animal feed can be met.

Description

technical field [0001] The invention belongs to the field of animal feed additives, in particular to a method for synthesizing betaine metal chelate assisted by microwaves. Background technique [0002] The molecular formula of betaine (trimethylaminoglycolactone) is (CH 3 ) 3 NCH 2 COO, no strong hygroscopicity, non-toxic, stable physical and chemical properties, high temperature resistance (200 ℃), widely distributed in nature. Betaine can participate in the methyl cycle in animals, and can be used as a nutritional feed additive to partially replace methionine to reduce the production cost of feed. [0003] Animals contain almost all trace elements in nature, and although the content of copper, manganese, and zinc in animal feed is small in poultry, it plays an important role. In feed addition, the sulfates or oxides of copper, manganese and zinc are generally added, which not only destroys the active ingredient phytic acid in the feed, but also inhibits each other, ca...
