Where Does Gelatin Come from?
Gelatin is a protein substance derived from collagen, a natural protein present in the tendons, ligaments, and tissues of mammals.
It is produced by boiling the connective tissues, bones and skins of animals, usually cows and pigs.
When you eat gelatin pudding, you are eating a protein food that comes from the bones of animals. To make gelatin, the bones are cleaned, crushed, and soaked in a strong acid. What’s left is a spongy material called ossein (AHS-ee-in).
The ossein is then cooked in order to release the gelatin. To make delicious gelatin desserts, the gelatin is sweetened and flavored with lemon, raspberry, and other flavors.
The gelatin mixture is then dried and ground into a powder. Gelatin forms a stiff jelly when dissolved in hot water and allowed to cool.
Gelatin’s ability to form strong, transparent gels and flexible films that are easily digested, soluble in hot water, and capable of forming a positive binding action have made it a valuable commodity in food processing, pharmaceuticals, photography, and paper production.
