Problems solved by technology

[0005] Although there are many studies on sucrose as feed, most of them are directly adding sucrose to the feed to feed livestock and poultry. This method will make the nutrients difficult to be absorbed and utilized by the body.
In addition, most of the feeds described in these inventions do not add trace elements. Even if a small amount of trace elements are added in individual inventions, they are added in the form of inorganic ions, which inevitably has the above-mentioned shortcomings of inorganic trace elements.

Abstract

The invention discloses a preparation method of a saccharose calcium complex. The preparation method includes the steps of: performing a complexing reaction to saccharose and calcium salt to obtain a saccharose calcium solution; cooling and filtering the saccharose calcium 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 calcium complex product; detecting the concentration of calcium ion in the residue, and adding the saccharose and the calcium salt according to the molar ratio of saccharose to calcium 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 calcium through circular reaction. The preparation method is free of resource waste, reduces production cost and increases production efficiency. The saccharose calcium 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 calcium complex and a preparation method thereof, and discloses its use. Background technique [0002] Calcium is the first mineral element in animals, and calcium accounts for 1%-2% of animal body weight. 99% of calcium is found in bones and teeth, with the remainder in soft tissue fluids. Clearly, calcium plays an important role in the development and maintenance of bones and teeth, and in addition, calcium has many important biological functions. Calcium plays a decisive role in blood coagulation, transmission of nerve impulses, muscle contraction, enzyme activity and hormone secretion. Calcium can regulate the excitability of muscles and nerves, and can activate or inhibit the activity of various enzymes. Calcium also has its own nutritional regulation function. When the supply of exogenous calcium is insufficient, the deposited calcium (especially in the bones) can be decomposed in large q...
