Gelatin or gelatine is a translucent, colorless, brittle (when dry), flavorless food derived from collagen obtained from various animal raw materials.
It is commonly used as a gelling agent in food, pharmaceutical drugs, photography, and cosmetic manufacturing. Substances containing gelatin or functioning in a similar way are called "gelatinous".
Gelatin is an irreversibly hydrolyzed form of collagen, wherein the hydrolysis results in the reduction of protein fibrils into smaller peptides, which will have broad molecular weight ranges associated with physical and chemical methods of denaturation,
based on the process of hydrolysis.
Collagen is a kind of fiber protein which is in the animal's bodies most, and is the main element of dermis and connective tissues and there is 90% of collagen in the protein which composes bone.
Collagen is dealt with hydrolysis with some enzymes and lower the molecular weight to 3000~20,000 for the good digestion. Then it is called as Collagen Peptides which are used for the food and beauty companies.
Dicalcium phosphate is mainly used as a dietary supplement in prepared breakfast cereals, dog treats, enriched flour, and noodle products. It is also used as a tableting agent in some pharmaceutical preparations,
including some products meant to eliminate body odor. Dibasic calcium phosphate is also found in some dietary calcium supplements.
It is used in poultry feed. It is also used in some toothpastes as a tartar control agent.
