Food additive: Calcium lactate
Food additive calcium lactate is a white or milky white powder or granule, non-toxic and tasteless, insoluble in ethanol and acetone. It is widely used in food, beverages, medicine and health care products, and is one of the essential mineral elements for the human body.
1. Physical and chemical properties of calcium lactate.
Calcium lactate is an organic salt with the chemical formula C6H10CaO6 and a molecular weight of 21825。Its appearance is white or milky white powder or granules, non-toxic and tasteless, insoluble in ethanol and acetone. The solubility of calcium lactate varies with temperature and the solubility is lower at 02g 100ml, 23g 100ml in methanol and 5 ml in ethanol5g/100ml。
Second, the production method of calcium lactate.
There are two main production methods of calcium lactate: fermentation method and synthesis method. The fermentation method is to use starch, molasses and other carbon-containing substances as raw materials, fermentation to obtain lactic acid, and then react with calcium carbonate or calcium hydroxide. The synthesis method uses acetic acid or acetone as raw material to obtain lactic acid through a series of chemical reactions, and then reacts with calcium hydroxide to obtain lactic acid.
3. The use of calcium lactate.
Calcium lactate is an important food additive, which is widely used in beverages, dairy products, bread, pastries and other foods. Calcium lactate can improve the taste and texture of food, improve the stability of food, and prevent food from spoiling. In addition, calcium lactate also has a certain preservative effect, which can inhibit the growth of bacteria in food. In the field of medicine, calcium lactate can be used for calcium supplementation and osteoporosis and other diseases. In the field of health supplements, calcium lactate is also often used as a calcium supplement.
Fourth, the safety of calcium lactate.
Calcium lactate is a safe food additive and is widely used in various types of food. According to the World Health Organization's assessment, the maximum daily dose of calcium lactate intake is 700 mg. However, for certain special populations, such as pregnant women, lactating women, and the elderly, more calcium supplementation may be required. When calcium lactate is used as a food additive, it should be used in strict accordance with the amount and scope of use specified in the national food safety standards to ensure food safety.
5. SummaryAs an important food additive, calcium lactate is widely used in beverages, dairy products, bread, pastries and other foods. It can not only improve the taste and texture of food, improve the stability of food, but also play a certain role in preservative. In the field of medicine and health products, calcium lactate also plays an important role. When calcium lactate is used as a food additive, it should be used in strict accordance with the amount and scope of use specified in the national food safety standards to ensure food safety. At the same time, consumers should also pay attention to the labels and instructions of the products when buying and eating foods containing calcium lactate to ensure their health and safety.
