Biodegradable Antimicrobial Food Packaging: Trends and Perspectives.

Area of Science:

• Materials Science
• Food Science
• Polymer Chemistry

Background:

• Traditional packaging materials contribute to pollution and lack active functionalities.
• There is a growing demand for sustainable and functional food packaging solutions.

Purpose of the Study:

• To review recent research trends and solutions in antimicrobial packaging materials.
• To highlight the evolution towards active, biodegradable, and edible packaging.

Main Methods:

• Review of scientific literature on antimicrobial packaging.
• Analysis of polymers (natural and synthetic) and active agents (natural and inorganic).
• Examination of incorporation methods for active substances (embedding, encapsulation, coating, grafting).

Main Results:

• Antimicrobial, antifungal, and antioxidant activities are achieved through polymer choice or additive incorporation.
• Biopolymers like polysaccharides, lipids, proteins, polylactic acid, and polyvinyl alcohol are key materials.
• Active substances include natural agents (bacteriocins, essential oils) and synthetic agents (nanoparticles, antibiotics).

Conclusions:

• The trend is towards sustainable, active packaging that enhances food safety and reduces waste.
• Antimicrobial packaging offers a path to diminish plastic pollution and improve resource management.
• Continued research and industry focus on these solutions are crucial for public health and environmental benefits.
