Introduction of Gelatin




Product name: Gelatin
CAS:9000-70-8
Molecular Formula:C6H12O6
Description of Gelatin:
Gelatin is a colorless, flavorless thickening agent that is used to give body to molded salads and desserts. A by-product of meat processing, most gelatin is granulated, although it is available in sheets-known as "sheet" or "leaf" gelatin-in some gourmet shops. The granulated type is sold in regular supermarkets and comes in unflavored and in flavored, sweetened varieties
Notes: Gelatin is flavorless and colorless, and if you dissolve it in a hot liquid, the liquid will gel as it cools. When reheated, say in your mouth, the gel melts.  Most of us know gelatin as the key ingredient in the quivering dessert we call Jell-O�, but cooks also use it to make cheesecakes, mousses, marshmallows, meringues, chiffon pies, ice cream, nougats, aspics, and many other things.   Gelatin will break down if exposed to the enzymes of certain raw fruits, like kiwi fruit, papayas, pineapple, peaches, mangos, guavas, and figs.  Cooking these fruits, though, destroys the enzymes.  If you plan to add these fruits to a gelatin salad, it's often easiest to buy them in cans, for all canned fruit is pre-cooked.  Gelatin is made from the bones, skins, hooves, and connective tissue of animals, including pigs, so it's objectionable to vegetarians and members of certain religions.  Kosher gelatins are available, and some of these are also vegetarian.
