Gelatin (from French gélatine) is a translucent, colorless, brittle, nearly tasteless solid substance, derived from the collagen inside animals' skin 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 hydrolyzed form of collagen. Gelatin is classified as a foodstuff, with E number E441. It is in almost every "gummy" confectionery as well as other products such as marshmallows and some low-fat yogurt. Some dietary customs forbid the use of gelatin from animal sources, and medical issues may limit or prevent its consumption by certain people.

1. Gelatine. – how is it actually produced

Gelatine is produced using raw materials taken from slaughtered cattle and pigs which were passed fit to enter the food chain. In Germany, some 90% of all edible gelatine is produced from pigskin and only 10% from bovine. In this latter case, the raw material is mostly hide, the thin collagenous layer located between the outer and inner layers of hide. Even in diseased animals, no infectivity has ever been detected in this material.Read More

2. Acid Manufacturing Process

The acid process is mainly used with pigskin and fish skin and sometimes bone raw materials. It is basically one in which the collagen is acidified to about pH 4 and then heated stepwise from 50°C to boiling to denature and solubilize the collagen.

3. Alkali Manufacturing Process

The alkali process is used on bovine hide and collagen sources where the animals are relatively old at slaughter. The process is one in which collagen is submitted to a caustic soda or lengthy liming process prior to extraction.
