Collagen is a protein found in animals (mainly mammals) and humans. Natural collagen is insoluble. Gelatin - usually extracted from the bones and skin of beef, pig or fish. It is a form of collagen that we use in food. Due to its functional versatility, it is irreplaceable in many applications. Collagen is not exactly the same as gelatin. Both are proteins made up of amino acids, but the amino chains of collagen are cut into smaller fragments through a specific hydrolysis process.
Collagen does not have the gelling function of gelatin and are soluble in cold water. They are highly digestible and bioavailable, and are used in dietary supplements and functional foods due to their proven health benefits.
