Ultrasound-assisted development and characterization of novel polyphenol-loaded pullulan/trehalose composite films for fruit preservation

Researchers developed a new type of edible food wrap made from natural plant materials (tea polyphenols, pullulan, and trehalose) treated with ultrasound. This wrap is stronger, more protective against oxygen and moisture, and kills harmful bacteria like E. coli and Staphylococcus aureus. When used to wrap fresh apples and pears, it significantly extended their shelf life by reducing browning and decay.

Development of Active Antibacterial CEO/CS@PLA Nonwovens and the Application on Food Preservation

Researchers created special biodegradable packaging material made from corn-based plastic combined with chitosan (from crab shells) and cinnamon oil. When placed over fresh strawberries, this material killed 99.99% of harmful bacteria and significantly extended shelf life. The packaging reduced strawberry decay, weight loss, and spoilage while maintaining nutritional quality.

Use of Limestone Sludge in the Preparation of ɩ-Carrageenan/Alginate-Based Films

Researchers have developed a method to convert limestone waste from stone quarries into a useful material for making biodegradable plastic films. By dissolving limestone in acid to extract calcium ions, they created a crosslinking solution that strengthens films made from seaweed-derived compounds like alginate and carrageenan. These films show promise as environmentally-friendly alternatives to conventional plastic packaging while helping solve industrial waste problems.

Beeswax-poly(vinyl alcohol) composite films for bread packaging

Scientists developed an eco-friendly plastic alternative made from polyvinyl alcohol and beeswax that can replace traditional petroleum-based plastics for wrapping bread. Through heat treatment and careful formulation, they created a material that keeps bread fresh nearly as well as regular plastic but is completely biodegradable. This innovation addresses environmental concerns about plastic waste while maintaining the freshness and quality of packaged foods.
