Product details
Vitamin C Calcium combines the same pharmacological effects of vitamin C and calcium, and can be used for the treatment of vitamin C and preventive treatment of calcium deficiency, and vitamin C made into calcium salts are more easily absorbed by the body, and the stability is enhanced.
In foreign countries, calcium vitamin C has been widely used in medicine and food industry. In the food industry, Calcium Vitamin C can be used as antioxidant, fortifier and additive of food.
Uses of Calcium Ascorbate.
As an antioxidant, China's regulations can be used in meat products and soups, the maximum use level of 1.0g/kg (in terms of ascorbic acid in fats and oils); used in instant noodles and pastries, the maximum use level of 0.2g/kg; can also be used as nutrient enhancers.
Pharmacological action of Calcium Ascorbate.
Calcium vitamin C is involved in amino acid metabolism, synthesis of neurotransmitters, collagen and interstitial tissues. Supplementation with appropriate amounts of calcium vitamin C promotes nutrient metabolism and energy production in the body, enhances immune function, improves vascular adaptability, improves the elasticity and tone of the skin, blood vessels, and other tissues, and improves the body's ability to respond to stress (e.g., infections, etc.).
In the body, ascorbic acid and dehydroascorbic acid form a reversible redox system which plays an important role in biological oxidation and reduction processes and cellular respiration.
Product Method of Bulk Calcium Ascorbate Powder.
With vitamin C and calcium carbonate as raw materials, the reaction is carried out without adding nitrogen: 44gVC and a certain amount of water are added to a three-necked bottle equipped with an electric stirrer, the reaction temperature is controlled with a water bath, and a certain amount of calcium carbonate is added slowly under uniform stirring to keep the liquid surface covered with CO2.
After the reaction is complete, the filtrate is transferred to a three-necked bottle, a large amount of methanol is added at room temperature, and the crystals are slowly alcohol precipitated, the temperature is continuously lowered after the addition, the filtration is carried out, washed with methanol, and dried in vacuum, and the finished product of calcium vitamin C is obtained. The optimal process conditions are: water addition 1mL/g, reaction temperature 50℃, reaction time 100min, feeding volume ratio VC:CaCO3=1:0.525.The average content of vitamin C calcium generated under these reaction conditions is 99.35%, and the yield reaches 86.91%.
