Abstract

The present invention proposes a process for preparing high-purity calcium glycinate by electrochemical-complexation reaction technology. The process uses calcium chloride solution with low added value as raw material, and utilizes a micro-electrolysis reaction system to form an alkaline environment that is conducive to the complexation reaction. The conditions are: continuous reaction and complexation in the complexing chamber to form a calcium glycinate complex, and alcohol washing, separation and drying to obtain calcium glycinate. In the process, the preparation of stable concentration water-soluble calcium glycinate complex solution is mainly completed by controlling voltage, complexation temperature, pH value, reaction ratio, alcohol-water ratio and other conditions, and the controllable washing of calcium glycinate in the alcohol washing tower Separation and precipitation, and finally high-purity calcium glycinate powder is obtained by low-temperature drying.

Description

technical field [0001] The invention is applied in technical fields such as food processing, medicine, electrodialysis, chlor-alkali industry, etc., and is used for preparing high-purity calcium glycinate. Background technique [0002] A large number of studies have shown that after calcium is combined with glycine, before entering the cell, it must first pass through the calcium channel on the brush border cell membrane of the small intestine, and the calcium channel has strict requirements on the molecular size, and the molecular weight is less than 1500 to pass through. The smaller the molecular weight, the better , and glycine has the smallest molecular weight and can easily pass through calcium channels. The chemical structure of calcium glycinate is stable, not affected by gastric acid, oxalic acid, etc., and can be completely absorbed by the body. After absorption, calcium can be directly transported to specific target tissues and enzyme systems, greatly improving the...
