Antimicrobial-loaded nanocarriers for food packaging applications

Area of Science:

• Food Science and Technology
• Materials Science
• Nanotechnology

Background:

• Consumer demand for organic and safer foods drives innovation in food preservation technologies.
• Active packaging (AP) incorporating natural antimicrobial agents offers a promising approach to extend food product shelf life.
• Traditional AP methods face limitations in delivering antimicrobial efficacy and stability.

Purpose of the Study:

• To review methods for designing novel encapsulation delivery systems for controlled release of antimicrobials in AP.
• To describe common nanocarriers used for encapsulating antimicrobial agents.
• To summarize the current applications of nanoencapsulated antimicrobials in antimicrobial AP development.

Main Methods:

• Literature review of nanoencapsulation techniques for antimicrobial agents.
• Analysis of various nanocarrier systems for controlled release applications in AP.
• Tabulation of current research on nanoencapsulated antimicrobials in active food packaging.

Main Results:

• Nanoencapsulation enhances the efficacy of natural antimicrobials in AP by providing protection and controlled release.
• Common nanocarriers include nanoparticles, liposomes, and solid lipid nanoparticles.
• Nanoencapsulated antimicrobials offer improved solubility, stability, and bioavailability compared to free forms.

Conclusions:

• Nanoencapsulation is a key strategy for overcoming barriers to using natural antimicrobials in food packaging.
• Incorporating nanoencapsulated antimicrobials into films or coatings is more effective than using free antimicrobials in AP.
• This approach significantly contributes to developing advanced active packaging for maintaining food quality and safety.
