Gelatin is a natural, biodegradable protein derived from the partial hydrolysis of collagen, a primary structural component found in animal connective tissues (e.g., skin, bones, and tendons of pigs, cattle, or fish). It exists as a translucent, flavorless solid that forms thermoreversible gels when hydrated and cooled. Gelatin is classified into two types based on production methods:
Type A: Acid-processed (typically from pork collagen).
Type B: Alkali-processed (typically from bovine sources).
Widely recognized for its versatility, gelatin is non-toxic, biocompatible, and complies with global food and pharmaceutical safety standards (e.g., FDA, USP, EP).
