Marmalade is loved by all children, and often from it is notrefuse and adults, but few people think about its composition. The basis of most jelly and marmalade is food gelatin, which is produced in huge quantities by industry. To answer the question of what gelatin is made from is not so simple, but we will try to do it.

In most cases, the classica method consisting in the processing of cartilage tissue and bones of animals, but sometimes skins are used. From the chemical point of view, during the technological process, the denaturation of collagen, which is the basis of protein fibers, which is rich in bone tissue and tendons, occurs. The cleavage is carried out by alkaline hydrolysis with the use of catalysts.

The resulting product has no taste and smell,it is used for the production of various jellies and other confectionery products. Vegetarians are horrified when they learn what food gelatin is made from, but for them there is a special composition that is obtained in another way - from algae. The vegetable substitute is called agar, and the raw material for it grows in the White Sea and in the Pacific Ocean.
