Preparation of calcium lactate

Gelatinization of rice by high pressure, diluted with water cooled to 50-53 ℃, access Aspergillus and Zinc lactate delbrueckii, lactic acid fermentation metabolites, calcium phosphate and then added to obtain a crude calcium lactate, and finally purified, or with calcium carbonate and dilute acid solution, and then the solution was evaporated in the system. Refining process is the use of magnesium hydroxide and ferrous lactate reacts with calcium, it is the nature of cohesion, so that part of the fermentation broth and protein impurities removed after condensation, and then concentrated in vacuo, crystallization, refining lactate.
