Specific optical rotation: 10.20 (C = 1, H2O22oC)
Properties: white crystalline or granular powder
Source: 1. Glucose oxidase and catalase were mixed with glucose and calcium carbonate, and calcium gluconate was directly obtained by oxidation at 37 degrees. 2. It can be obtained by neutralizing gluconic acid with lime or calcium carbonate and concentrating.
Applications: First, as a calcium fortifier, buffer, curing agent, chelating agent. Second, calcium supplementation. Third, calcium gluconate as a food calcium fortifier, absorption effect is better than inorganic calcium. China's regulations can be used for cereals and their products, the amount of use is 18 ~ 36g. Fourth, as a drug, it can reduce capillary permeability, increase density, maintain normal excitability of nerves and muscles, strengthen myocardial contractility, and help bone formation. Suitable for allergic diseases such as urticaria; eczema; pruritus; contact dermatitis, and serum disease; angioedema as an adjuvant therapy. Also suitable for convulsions and magnesium poisoning caused by hypocalcemia. Also used to prevent and treat calcium deficiency. As a food additive, used as a buffer; curing agent; chelating agent; nutritional supplement.
Packing: 1-5 kg / aluminum foil bag, 25KG / cardboard drum
