Gelatin vs. Jello: What's the Difference?
Gelatin
Gelatin or gelatine (from Latin: gelatus meaning “stiff”, “frozen”) is a translucent, colorless, brittle (when dry), flavorless food ingredient that is derived from collagen obtained from various animal body parts. It is commonly used as a gelling agent in food, medications, drug and vitamin capsules, photographic films and papers, and cosmetics.
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.
