Gelatin(or Gelatine) is a translucent, colorless, brittle (when dry), flavorless solid substance, derived from the collagen mainly inside beef skin (hide) and 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.
