Problems solved by technology

[0005] At present, amino acid chelated calcium is produced by pure chemical methods, that is, amino acids and calcium hydroxide are mixed in a certain proportion in a closed container for reaction. However, the above-mentioned method has the following disadvantages: (1) The preparation time is long and the yield is low. (2) The chelation rate is low and the reaction is incomplete; (3) The solubility in water is low, which affects the absorption

Abstract

The invention relates to a preparation method of amino acid chelated calcium. The preparation method comprises the following steps: preparing a mixture by mixing a calcium-containing compound and an amino acid ligand according to a specific ratio, adding a right amount of water into the mixture, performing primary filtration on the material to obtain a first suspension having a solid particle size less than 20 mu m, regulating the pH value, performing homogenization treatment to enable the solid particle size to reach the nano level, performing secondary filtration after the homogenization treatment filtration a second suspension having a solid particle size less than 100 nm, and finally performing chelation reaction on the second suspension at specific temperature and pressure. Thus, the chelation rate and the reaction efficiency of the chelation reaction are greatly improved, the reaction time is short, and the reaction is complete. The amino acid chelated calcium is high in yield; the mass percent of the calcium element in the amino acid chelated calcium is up to 12.9%; and the amino acid chelated calcium prepared by the method can be absorbed by a human body very easily, and the absorptivity is up to 95% or above.

Description

Technical field [0001] The invention belongs to the technical field of calcium supplements, and specifically relates to a preparation method of amino acid chelated calcium and a calcium supplement preparation comprising the chelated calcium. Background technique [0002] Calcium is one of the most important elements of the human body. The function of almost every system of the human body is related to calcium. The harm of calcium deficiency to the human body has become a remarkable worldwide problem. Especially the impact on infants, the elderly, pregnant women and patients with certain diseases is more serious. Scientific calcium supplementation, beneficial to health, has become a consensus of people. Normal people’s daily physiological requirement for calcium is 300-500 mg, while according to Chinese eating habits, the daily calcium intake from food is only 150-200 mg. [0003] According to incomplete statistics, there are currently more than 200 calcium supplements on the dome...
