Problems solved by technology

[0007] However, although the bioavailability of amino acid complexed (chelated) trace elements synthesized by lysine, methionine, glycine, etc. with higher prices is higher, its use cost is also relatively high, especially in the current highly competitive feed market. Under the environment, the need to reduce the cost of use is increasingly prominent

Abstract

The invention discloses a preparation method for saccharose zinc complex. Saccharose and heptahydrate are subjected to a complex reaction, and a saccharose zinc solution is obtained; then, the saccharose zinc solution is cooled and filtered, filter residues and filtrate are obtained, ethanol water is added into the filtrate, complex precipitates, precipitate is subjected to centrifugal suction filtration and vacuum drying to be dried, and a pure saccharose complex zinc product is obtained; the zinc ion concentration of the filter residues is detected, according to the molar ratio being 1:4 of saccharose and zinc ions, saccharose and heptahydrate continue to be added, waste water obtained after centrifugal suction filtration is returned to a reaction kettle to serve as mother liquid for dissolving saccharose, a circular reaction is conducted, and saccharose zinc continues to be generated. In the process of preparing the saccharose zinc, no resources are wasted, the production cost is reduced, and the production efficiency is improved. The obtained saccharose zinc has the advantages of being safe, efficient and high in cost performance and can be applied to production of animal feed with comprehensive nutrition.

Description

technical field [0001] The invention relates to a complex, especially a sucrose-zinc complex and a preparation method thereof, and discloses its use. Background technique [0002] Zinc is an essential trace element for animals. It is not only necessary to maintain the growth and development of animals, but also the key to the normal development of the animal immune system and the maintenance of immune functions. Zinc is a component or activator of various enzymes in animals, including alkaline phosphatase, carbonic anhydrase, alcohol dehydrogenase, lactate dehydrogenase, glutamate dehydrogenase and carboxypeptidase, etc. Zinc and Ribonucleic acid, deoxyribonucleic acid, and protein biosynthesis are closely related, and zinc is also a component of insulin. When animals are deficient in zinc, they manifest as loss of appetite and growth retardation, followed by incomplete keratinization of the skin. Zinc deficiency also affects the development of animal bones and deforms long...
