In situ crosslinked Schiff base biohydrogels containing Carica papaya peel extract: application in the packaging of fresh berries
Summary
Researchers developed biohydrogels using papaya peel extract crosslinked via Schiff base chemistry, creating antimicrobial and antioxidant packaging films that extended the shelf life of fresh berries by leveraging fruit waste as a functional ingredient.
Although endowed with antimicrobial and antioxidant properties, fruit peel is often regarded as waste.

Exploring Agricultural and Industrial Fruit-Based Waste/By-products for Eco-friendly Multifunctional Bio-based Food Packaging and Coating Materials
Researchers reviewed how agricultural and industrial fruit waste — including peels, seeds, and pomace — can be converted into multifunctional bio-based food packaging materials with demonstrated antimicrobial, antioxidant, and shelf-life-extending properties, while identifying scalability and regulatory alignment as key barriers to widespread adoption.
Carrageenan-Based Films Incorporated with Jaboticaba Peel Extract: An Innovative Material for Active Food Packaging
This study developed carrageenan-based food packaging films enriched with jaboticaba berry peel extract, which has natural antimicrobial and antioxidant properties. Developing effective biodegradable food packaging alternatives could help reduce the use of conventional plastic packaging, a major source of microplastic pollution.
Chitosan-Based Films Blended with Tannic Acid and Moringa Oleifera for Application in Food Packaging: The Preservation of Strawberries (Fragaria ananassa)
Researchers developed biodegradable food packaging films made from chitosan blended with tannic acid and moringa seed powder, and tested them for strawberry preservation. They found that the bio-based films extended strawberry shelf life while providing antimicrobial properties, offering a potential alternative to conventional plastic packaging. The study suggests that natural polymer-based packaging materials could help reduce plastic waste in the food industry.
Development and characterization of active gelatin-chitosan packaging incorporated with guava leaf extract for extending meat shelf life
Researchers developed active food packaging films made from gelatin and chitosan incorporating natural antimicrobial agents, evaluating their barrier properties, mechanical strength, and ability to extend food shelf life. The bio-based packaging showed effective antimicrobial activity and reduced food spoilage compared to untreated films.
An overview: exploring the potential of fruit and vegetable waste and by-products in food biodegradable packaging
Researchers reviewed how fruit and vegetable processing waste — rich in polyphenols, vitamins, and fiber — can be transformed into biodegradable food packaging films and coatings, offering an eco-friendly alternative to conventional plastic packaging. Repurposing food waste this way could simultaneously reduce plastic pollution (including microplastics from packaging degradation) and address agricultural waste disposal challenges.
