What kind of food additive is calcium carbonate

Introduction: as a food additive, calcium carbonate plays an important role in many foods What kind of food additive is calcium carbonate? Calcium carbonate is an inorganic compound, commonly known as limestone, limestone, stone powder, marble and calcite It is a compound Its chemical formula is CaCO ₃, which is neutral, basically insoluble in water and soluble in acid It is a common material on the earth, existing in aragonite, calcite, chalk, limestone, marble, travertine and other rocks It is also the main component of animal skeleton or shell Calcium carbonate is an important building material, which is widely used in industry It is also a common reagent in chemistry of junior and senior high school (it is often used to react with hydrochloric acid to form CO 2, etc.) So what kind of food additive is calcium carbonate? Light calcium carbonate can be used as bulking agent, flour treatment agent, anti caking agent, acidity regulator, nutrition enhancer, curing agent, etc According to GMP, it can be used in all kinds of food and gum base which need to add expanding agent It can also be used as flour improver with the maximum dosage of 0.03%; milk powder of 7.5-18g/kg; soybean milk powder and soybean powder of 4-20g / kg; soft drink of 0.4-3.4g/kg; lotus root powder of 6-8g / kg; instant breakfast cereal of 2-7g / kg FDA (184.1192200) does not make restrictive regulations, according to GMP When the product is used as bulking agent, it is often used in combination with other varieties, and the bulking agent obtained by compounding with sodium bicarbonate, alum, etc will slowly release carbon dioxide in case of heat, so that the food will produce even and delicate bulking body, which can improve the quality of pastry, bread, biscuit In addition, it can strengthen the role of calcium, the smaller the calcium carbonate particles, the easier to absorb In Japan, light calcium carbonate is used as a bulking agent, and the dosage in general food is 1% Calcium carbonate is used for making powder, powder, gouache, rouge and other raw materials When making powder cosmetics, it is used as a mixture of flavors It is also mainly used as toothpaste as a friction agent, and belongs to the hard abrasive material for toothpaste Nowadays, many foods have food additives, so what is food additives? In fact, food additives are synthetic or natural substances added into food to improve the quality of food such as color, fragrance and taste, as well as the needs of antisepsis and processing technology Some food additives are harmful to human body, but China's food safety detector can accurately check whether the food is safe and whether there is excessive use of additives, so that we can eat food more safely If you want to know more about food additives, please go to Baibai safety net Editor in charge: he xianrob
