A pH-sensitive film based on chitosan/gelatin and anthocyanin from Zingiber striolatum Diels for monitoring fish freshness

mycolabadmin

Researchers developed a smart packaging film that changes color to show whether fish is fresh or spoiled. The film combines chitosan and gelatin with a natural purple dye from Zingiber striolatum plants, creating an intelligent label that shifts from deep purple to brown as the fish deteriorates. This color change accurately reflects the fish’s pH and ammonia levels, allowing consumers to visually determine freshness without opening the package.

Effect of AgNPs on PLA-Based Biocomposites with Polysaccharides: Biodegradability, Antibacterial Activity and Features

mycolabadmin

Scientists created new eco-friendly plastic films made from corn-based PLA combined with natural starches and tiny silver particles. These films can break down in soil while also killing harmful bacteria, making them ideal for food packaging. The materials maintained good antibacterial properties even as they slowly degraded in the environment, showing promise as sustainable alternatives to conventional plastics.

Advancing Food Preservation: Sustainable Green-AgNPs Bionanocomposites in Paper-Starch Flexible Packaging for Prolonged Shelf Life

mycolabadmin

Researchers developed an eco-friendly food packaging material by coating paper with corn starch and tiny silver particles created through green chemistry methods. This innovative packaging significantly improved food durability, reducing weight loss in fresh produce like tomatoes and grapes by 6-8% over six days. The material is completely biodegradable and poses no safety concerns, making it a sustainable alternative to traditional plastic packaging.

Agricultural Waste-Derived Biopolymers for Sustainable Food Packaging: Challenges and Future Prospects

mycolabadmin

This review explores how agricultural waste like rice husks and corn cobs can be transformed into eco-friendly packaging materials to replace harmful plastic. Currently, most plastics take hundreds of years to decompose and cause serious environmental damage, but biopolymers derived from farm waste are completely biodegradable. The article discusses various ways to extract these materials and improve their properties, while identifying remaining challenges that need to be solved before widespread commercial adoption.

Microbial-Based Green Synthesis of Silver Nanoparticles: A Comparative Review of Bacteria- and Fungi-Mediated Approaches

mycolabadmin

Scientists have developed environmentally friendly ways to create tiny silver particles using bacteria and fungi instead of harsh chemicals. These silver nanoparticles can fight bacteria, help treat cancer, clean contaminated water, and improve food packaging. The review shows that bacteria produce particles quickly but fungi are better for large-scale production and create more stable particles.
