Product Description

Calcium carbonate is an inorganic compound with the chemical formula CaCO3. It is the main component of limestone, marble, etc. Calcium carbonate is usually white crystals, odorless, basically insoluble in water, and easily reacts with acids to release carbon dioxide. It is one of the common substances on the earth. It is found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also the main component of some animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry.

The role of food additive calcium carbonate
Calcium carbonate is a commonly used food additive. Its main functions are:
1. Adjust pH: Calcium carbonate can neutralize excessive acidic substances in food, adjusting the pH value of food, thereby improving the stability and quality of food.
2. Improve food quality: Calcium carbonate can neutralize or absorb acidic substances, odors and other substances in food, thereby improving its taste, quality and stability.
3. Calcium supplementation effect: Calcium carbonate contains a large amount of calcium, which can supplement the calcium needed by the human body. It is especially important for people who are prone to calcium deficiency such as children and the elderly.
4. Preservative: Calcium carbonate can reduce the conditions for the growth of microorganisms in food by absorbing moisture, thereby achieving the preservative effect.
In short, calcium carbonate has a wide range of functions and is a common food additive. However, excessive use of carbonic acid
Calcium affects the taste and health of food, so it needs to be used within an appropriate range.
