Area of Science:

• Materials Science
• Polymer Science
• Food Science

Background:

• Polysaccharides offer renewable, biodegradable, and biocompatible edible packaging solutions.
• Single-component polysaccharide films often exhibit undesirable properties, limiting their application.
• Ternary blend-based bio-packaging is explored to enhance characteristics and properties.

Purpose of the Study:

• To review the extraction and combination of polysaccharides with other polymers for improved biodegradable films.
• To explore advancements in ternary blend-based biodegradable films and their food applications.
• To discuss future prospects for developing advanced biodegradable films.

Main Methods:

• Review of literature on polysaccharide extraction and modification.
• Analysis of ternary blend formulations and their impact on film properties.
• Evaluation of physico-mechanical and barrier properties of developed films.

Main Results:

• Ternary blends significantly improve the characteristics and properties of biodegradable films compared to single or binary systems.
• Films based on cellulose, modified starch, and other plant polysaccharides exhibit good gas barrier properties and tensile strength.
• These advanced films show potential for protecting perishable and semi-perishable foods.

Conclusions:

• Ternary blend-based bio-packaging represents a significant advancement in green packaging technology.
• Polysaccharide-based films, particularly ternary blends, can effectively replace conventional synthetic packaging for certain food applications.
• Further development of advanced biodegradable films holds promise for sustainable food preservation.
