1. Anti-caking Agent - Prevents lumps from forming in food due to excess water. They usually function as a water repellent or by absorbing excess moisture.
2. Colorant - Pigments or dyes that are added in order to change or enhance the color.
3. Emollient - Softens and soothes the skin. Helps with skin conditioning.
4. Pearlescents / Pearlizer - Provides luster and shimmering effects
Gastric-peptic disease occurs as a result of an imbalance between protective factors, such as mucus, bicarbonate , and prostaglandin secretion, and aggressive factors, such as hydrochloric acid , pepsin, and Helicobacter pylori ( H. pylori ). Antacids work by restoring acid-base balance, attenuating the pepsin activity and increasing bicarbonate and prostaglandin secretion. The acid-neutralizing capacity of calcium carbonate is 58 mEq/15 ml. When used as a nutritional supplement, calcium carbonate acts by directly increasing calcium stores within the body. Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis.
Calcium carbonate is used in the production of calcium oxide as well as toothpaste and has seen a resurgence as a food preservative and color retainer, when used in or with products such as organic apples. As a food additive it is designated E170 and also used as an acidity regulator, anticaking agent, stabiliser or colour. It is used in some soy milk and almond milk products as a source of dietary calcium. Calcium carbonate is also used as a firming agent in many canned or bottled vegetable products.
It is approved to use as food and cosmetics coloring in EU. In US, it is no longer authorized to use a color additive in food but is allowed to use in drugs.
