Embodiment Construction

[0017] raw material Dosage ratio Actual amount added glucose 100% 1112g calcium carbonate 51% 566.5g lactic acid 100% 1112g glucose oxidase 1.2% 4.62ml Catalase 0.8% 5.94ml

[0018] Note: The proportion of raw materials in the above table refers to the weight % of other raw materials required based on the conversion of raw material glucose into 100% dry basis (the same below).

[0019] The raw materials in the above table were used to prepare 6000 ml of reaction liquid, and the reaction temperature was 35°C. Introduce sterile air, control the ventilation rate to 1:1v / v / min, keep the pressure of the reaction tank at 0.2MPa, and the reaction period is 25 hours. When the concentration of reducing sugar in the reaction solution drops to ≤0.1%, the reaction is terminated. Heat the reaction solution to 95°C to inactivate the enzyme, add activated carbon at 0.1% (W:V) to decolorize at 60°C for 1 hour, filter to obtain the filtrate...

Abstract

The invention relates to a preparationg method of calcium lactate gluconate. Calcium lactate gluconate is prepared through double enzyme catalysis with glucose, calcium carbonate and lactic acid as raw materials, and catalase and glucose oxidase as enzyme catalysts. The raw materials concretely comprise 100wt% of glucose, 50-60wt% of calcium carbonate and 30-100wt% of lactic acid; and the addition amount of catalase is 0.3-1.2% of the amount of a glucose dry basis, and the addition amount of glucose oxidase is 0.5-1.5% of the amount of the glucose dry basis. The calcium lactate gluconate product prepared by adopting the method has the advantages of high purity and high solubility, can be used as a new calcium supplements, and has significant advantages.

Description

technical field [0001] The invention belongs to the technical field of producing calcium gluconate lactate, in particular to a method for preparing calcium gluconate lactate by a dual-enzyme method. Background technique [0002] Calcium is one of the important elements in the human body. 99% of the calcium in the human body is deposited in the bones, and the remaining 1% is in the blood circulation system. Calcium has important physiological and biochemical functions. Its main function is to form bones, maintain the normal excitement of nerves and muscles, reduce the permeability of capillaries, and participate in the process of blood coagulation. Calcium is constantly consumed and must be supplemented by diet. However, the lack of calcium in my country's dietary nutrition is the most serious, and the average calcium intake only reaches 50% of the daily supply, and the lack of calcium is more obvious among pregnant women, children, and the elderly. Therefore, it is an urge...
