Renovation of Agro-Waste for Sustainable Food Packaging: A Review

mycolabadmin

This review explores how agricultural waste can be transformed into eco-friendly food packaging materials. Researchers are finding ways to extract valuable compounds like cellulose from crop residues and chitin from shrimp shells to create biodegradable packaging films that preserve food while reducing environmental pollution. These sustainable packaging alternatives perform as well as conventional plastics while being completely biodegradable, representing an important step toward a circular economy and reducing agricultural waste.

Caseinate–Carboxymethyl Chitosan Composite Edible Coating with Soybean Oil for Extending the Shelf Life of Blueberry Fruit

mycolabadmin

This study developed a special edible coating made from natural proteins and carbohydrate polymers with soybean oil to keep blueberries fresh longer. When blueberries were dipped in this coating and refrigerated, they lost less water, stayed firmer, and developed less mold compared to uncoated berries. The coating worked like an invisible protective layer that helped blueberries maintain their quality for up to 28 days, potentially reducing food waste and spoilage.
