Problems solved by technology

[0004] At present, in the existing methods for preparing methionine trace element chelates, there is a phenomenon of low product purity and poor stability, which is not conducive to the digestion and absorption of animals.
In addition, the amount of methionine in the prior art greatly exceeds the amount of trace elements, which increases the cost

Embodiment 1

[0014] Dissolve glycine (15g, 0.2mol) in 100ml water, add CaO5.7g (0.1mol) (or 7.4g Ca(OH) 2 ). The system was stirred until CaO was dissolved. After 30 min, copper sulfate pentahydrate (25.4 g, 0.1 mol) was added to the system. After a few minutes, the system became viscous and reacted for 30 minutes. After the reaction, 80ml of water was added to the system, the system was heated to 70-80°C, filtered, and the filter cake was washed twice with water. The filtrate was concentrated to dryness in vacuo. 21 g of a blue powder solid was obtained.

Embodiment 2

[0016] Glycine (25g, 0.33mol) was dissolved in 120ml of water, and CaO (9.5g, 0.168) was added. The system was stirred until CaO was dissolved. After 30 min, zinc sulfate heptahydrate (47.8 g, 0.165 g) was added to the system. After reacting for 30 minutes, filter and wash the filter cake twice with water. The filtrate was concentrated to dryness to obtain 35 g of white powder solid.

Embodiment 3

[0018] Dissolve glycine (15g, 0.2mol) in 100ml of water, add CaO (5.7g, 0.1mol) and stir the system until CaO is dissolved. After 30 minutes, manganese sulfate monohydrate (16.9 g, 0.1 mol) was added to the system. React for 30 minutes. After the reaction, filter and wash the filter cake twice with water. The filtrate was concentrated to dryness in vacuo. 20 g of a light brown powder solid was obtained.

Abstract

The invention provides a preparation method of a glycine trace element chelate with high purity. The method comprises the following steps: first, dissolving a certain amount of amino acid in water; reacting the amino acid aqueous solution and calcium oxide or calcium hydroxide at room temperature to obtain a calcium amino acid chelate solution; and then reacting the calcium amino acid chelate solution with metal sulfate to obtain a target compound. The method provided by the invention prepares the glycine trace element chelate with high purity at a low cost; and the chelate has high stability, is conducive to digestion and absorption of animal body, and can be used as a feed additive.

Description

technical field [0001] The invention relates to a method for preparing high-purity amino acid trace element chelate, in particular to a method for preparing glycine trace element chelate. Background technique [0002] For a century, the use of trace elements as feed additives has gone through three stages of development: initially, inorganic salts of trace elements, mainly sulfates and oxides, were used, but many defects were found in the application. For example, antagonism with other nutrients, damage to vitamins and other nutrients, low biological potency and low mixing uniformity, etc. To overcome these shortcomings, people began to use the second generation of trace element additives - organic acid salts. It also has shortcomings such as low biological utilization rate and unstable biochemical function. Trace element amino acid chelate is a new type of high-efficiency feed additive that was first successfully developed by the ALBICN biological laboratory in the Unite...
