Gelatine is obtained through partial hydrolysis of collagen contained in animal skins and bones. It is a natural protein food typically consisting of 85% protein, 13% water and 2% minerals for a caloric value of 370 kcal. It is classified as a foodstuff by the majority of administrative authorities and has received the GRAS status from the FDA.

This protein is fully digestible and contains 18 different amino-acids, including all of the 9 essential amino-acid but tryptophan. It is particularly rich in Glycine, Proline and Hydroxyproline, which, all together, represent almost 50% of the composition of the molecule. Hydroxyproline is an amino-acid specific of gelatine.

Gelatin is water soluble and compatible with most other hydrocolloids, including vegetal colloids such as agar-agar, alginates, carrageenans or pectins. It is compatible with sugars, corn syrups, edible acids and flavors.
