The preparation method of our calcium glycine chelate is as follows: dissolve glycine in deionized water, stir to dissolve it completely, add basic sodium carbonate in the ratio of molar ratio 1:2: into the glycine aqueous solution, start the water bath to stir, and then add a certain proportion of anhydrous calcium chloride to mix the raw material into the aqueous solution
The reaction is synthesized by stirring under heated conditions for a period of time. The reaction solution is transferred to a rotary evaporator to evaporate and concentrate until particles come out, and the solution containing solids is removed, and the filtered solids are put in a vacuum drying oven and dried at 60℃. Finally, the product is crushed by a mill and stored in a drying bottle for later use.
