Nanocomposite-Enabled Next-Generation Food Packaging: A Comprehensive Review on Advanced Preparation Methods,...

Area of Science:

• Materials Science
• Food Science
• Nanotechnology

Background:

• Food spoilage presents significant economic and quality challenges.
• Conventional packaging materials often lack sufficient barrier and antimicrobial properties.
• Nanocomposites offer potential solutions for advanced food preservation.

Purpose of the Study:

• To review nanocomposite packaging materials for food preservation.
• To examine their preparation, properties, applications, and safety.
• To identify future research directions.

Main Methods:

• Comprehensive literature review of nanocomposite packaging.
• Analysis of preparation techniques (e.g., ionic gelation, electrospinning).
• Evaluation of functional properties and safety considerations.

Main Results:

• Nanocomposites exhibit enhanced mechanical strength and barrier properties (reduced permeability).
• Demonstrated significant antimicrobial activity against foodborne pathogens.
• Effective in extending shelf life for fruits, vegetables, meats, and dairy products.

Conclusions:

• Nanocomposite packaging shows great promise for food preservation.
• Potential cytotoxicity and nanoparticle migration require thorough safety assessment.
• Scalable, eco-friendly production and standardized safety protocols are needed for commercialization.
