Special Issue Information

Dear Colleagues,

Food packaging has become an important and indispensable part of food, which has a direct or indirect impact on food quality. Traditional packaging materials are difficult to degrade, causing heavy pollution, toxicity and other shortcomings. New environmentally friendly packaging materials for the inhibition of pathogens and maintaining freshness, have significant advantages. In recent years, with the increasing awareness of environmental protection, people have put forward higher requirements on the functionality and environmental characteristics of food packaging materials.

This Special Issue will focus on the synthesis, characterization, and application of existing and novel food packaging materials, with an emphasis on their biological and molecular research. Topics of interest include, but are not limited to:

1. Synthesis and Characterization of Novel Food Packaging Materials

  • Synthesis and performance optimization of nanomaterials, bio-based materials, and biodegradable materials.
  • Structure-function relationship studies, including mechanical properties, barrier properties, and thermal stability.

2. Biocompatibility and Safety of Food Packaging Materials

  • Biological effects assessment of novel packaging materials in contact with food.
  • Migration behavior and health risks of nanomaterials used in food packaging.

3. Molecular Mechanisms of Biodegradable and Edible Packaging Materials

  • Degradation pathways of biodegradable materials and their environmental impacts.
  • Component optimization of edible packaging materials and their potential applications in food.

4. Antimicrobial and Freshness Preservation Properties of Food Packaging Materials

  • Inhibitory effects and molecular mechanisms of novel packaging materials against foodborne pathogens.
  • Applications of packaging materials in extending the shelf life of food products.

5. Intelligent and Active Packaging Technologies

  • Response mechanisms of intelligent packaging materials and their applications in food preservation.
  • Molecular mechanisms of active packaging materials, such as antimicrobial and antioxidant materials.

We are pleased to invite you to submit your original research findings for a Special Issue in the International Journal of Molecular Sciences entitled ‘Insights into Novel Food Packaging Materials: Properties, Molecular Mechanisms, and Advanced Applications’. The scope of this Special Issue includes all aspects related to food packaging and new packaging materials.

This Special Issue will mainly contain original research papers, review articles, and short communications.

We look forward to receiving your contributions.

Curcumin exhibits antioxidant, antibacterial, antitumor, and anti-inflammatory biological properties. Its dual functionality as both a food additive and a pH-sensitive colorant has led to extensive applications in meat products and other food systems, thereby garnering significant research interest.

Curcumin exhibits antioxidant, antibacterial, antitumor, and anti-inflammatory biological properties. Its dual functionality as both a food additive and a pH-sensitive colorant has led to extensive applications in meat products and other food systems, thereby garnering significant research interest. In recent years, curcumin-loaded active-intelligent food packaging films have emerged as a promising innovation due to their multifunctional capabilities: not only do they prevent microbial contamination and extend food shelf life, but they also enable real-time freshness monitoring through visual colorimetric responses. This paper first delineates the molecular structure and fundamental biological mechanisms of curcumin. Subsequently, it systematically reviews the strategies for curcumin incorporation (including encapsulation techniques and composite formulations) and advanced fabrication methodologies for developing active-intelligent biodegradable films. Finally, the current applications of curcumin in polymer-based smart packaging systems are critically analyzed, with prospective research directions proposed to address existing technological limitations.
