Gelatin is a significant multifunctional biopolymer that
is widely
utilized as a component in food, pharmaceuticals, and cosmetics. Numerous
functional qualities are displayed by gelatin, such as its exceptional
film-forming ability, gelling qualities, foaming and emulsifying qualities,
biocompatibility and biodegradable qualities. Due to its unique structural,
physicochemical, and biochemical characteristics, which enhance nutritional
content and health benefits as well as the stability, consistency,
and elasticity of food products, gelatin is utilized extensively in
the food business. Additionally, gelatin has demonstrated excellent
performance in encapsulating, delivering, and releasing active ingredients.
Gelatin’s various modifications, such as chemical, enzymatic,
and physical processes, were analyzed to assess their impact on gelatin
structures and characteristics. Hopefully, gelatin will be more widely
used in various applications after modification using suitable methods.
