Gelatin (or Gelatine) is a translucent, colorless, brittle (when dry), flavorless solid substance, derived from the

collagen mainly inside pig skin (hide) and cattle bones. It is commonly used as a gelling agent in food, pharmaceuticals,

photography, and cosmetic manufacturing. Substances containing Gelatin or functioning in a similar way are called Gelatinous.

Gelatin is an irreversibly hydrolysed form of collagen, and is classified as a foodstuff. It is found in some gummy candies

as well as other products such as marshmallows, Gelatin dessert, and some ice cream and yogurt. Household Gelatin comes in

the form of sheets, granules, or powder.  http://www.ytfoodchem.com/
