Preparation method of saccharose copper complex

Abstract

The invention discloses a preparation method of a saccharose copper complex. The preparation method includes the steps of: performing a complexing reaction to saccharose and copper salt to obtain a saccharose copper solution; cooling and filtering the saccharose copper solution to obtain residue and filtrate; adding an ethanol water solution to the filtrate to precipitate a complex; centrifugally suction-filtering and vacuum-drying the precipitate to obtain a pure saccharose copper complex product; detecting the concentration of copper ion in the residue, and adding the saccharose and the copper salt according to the molar ratio of saccharose to copper ion being 1:4, and feeding the waste water obtained in the centrifugal suction filtration back to the reaction kettle to serve as a mother liquid for dissolving the saccharose, thereby continuously producing saccharose copper through circular reaction. The preparation method is free of resource waste, reduces production cost and increases production efficiency. The saccharose copper complex is safe, is high-effective and is high in cost-performance ratio, and can be used for preparing animal feeds having comprehensive nutrition.

Description

technical field [0001] The invention relates to a complex, especially a sucrose copper complex and a preparation method thereof, and discloses its use. Background technique [0002] In 1928, Hart of the University of Wisconsin (WisconsinUniversity) studied rats with anemia after feeding milk and proposed that the addition of copper and iron was necessary for the formation of heme, and the importance of copper in nutrition was recognized. admit. Subsequent studies have successively confirmed that copper is closely related to the hematopoietic process of the body. Hypochromic microcytic anemia after copper deficiency in animals. Further studies have shown that copper is involved in the hematopoietic process by affecting the absorption, release, transport and utilization of iron. An appropriate amount of copper can promote the absorption of iron in the intestine, promote the iron in the body to enter the bone marrow from the storage place, change inorganic iron into organic ...

Problems solved by technology

At present, inorganic trace elements such as copper sulfate are mostly used in production and practice. The following defects exist in the use of inorganic trace elements: low bioavailability, animals can only use inorganic trace elements with an added amount of less than 10%, and the unused part is Excluded from the body, it not only causes waste but also increases the burden on the animal body and the environment; in addition, ionic trace element metal ions are affected by phytic acid, oxalic acid and cellulose in the intestinal tract, further reducing their absorption rate; at the same time, the antagonism between elements It also affects the biological potency. The oxidation-reduction reaction between metal ions will damage vitamins, thereby causing the loss of nutrients and reducing their absorption and utilization.

[0012] However, although amino acid complexed (chelated) trace elements synthesized with relatively expensive lysine, methionine, glycine, etc. have high biological potency, their use costs are relatively high, especially in the current highly competitive feed market. Under the environment, the need to reduce the cost of use is increasingly prominent
