If it jiggles it's fat! - Arnold Schwarzenegger, the bodybuilding guru, once said. What a chemical engineer would say? Arnold, you got it all wrong - it's JELLY!
Gelatin was first derived in 1682 by Denis Papin who invented a steam digester. He used it to intensively cook animal bones. Still, it took two more centuries before the first industrial manufacture of gelatin came about in 1818. Nowadays, the modern production technologies allow the processors to preset and monitor ingredient amounts as well as time and temperature. This also enables the monitoring of acidity, alkalinity, and flow levels. Very often valves are installed along pipelines to enable continuous sampling of the product.
Gelatin is produced by partial hydrolysis of collagen. There are many processes which aid this conversion. However, they all have certain factors in common. The intermolecular and intramolecular bonds which stabilize insoluble collagen have to be broken. Also the hydrogen bonds which stabilize the collagen helix need to be disintegrated. What makes it water soluble? Its chemical structure.
