In a significant advancement for sustainable food practices, researchers at The University of the South Pacific (USP) have introduced an innovative edible and biodegradable food coating derived from cassava starch. This initiative, led by Associate Professor David Rohindra and his team from USP’s Discipline of Chemistry, aims to revolutionize food packaging and preservation methods globally.
The cassava-based coating is engineered to extend the shelf life of tropical fruits, specifically mangoes, by hastening the drying process while also preventing infestations from fruit flies. Formulated with agar, glycerol, and clove essential oil, this coating utilizes the principles of osmosis to enhance dehydration and protect fruits from pests, addressing a critical issue in tropical agriculture.
Associate Professor Rohindra emphasized the potential of cassava, which is plentiful in the Pacific, stating, “Its starch has excellent film-forming properties.” By supplementing it with natural additives, the team has created a safe, edible, and environmentally sustainable alternative to conventional plastic packaging.
This groundbreaking technology builds on previous research by Rohindra, which demonstrated the benefits of cassava starch coatings in prolonging the freshness of eggs by reducing moisture loss and microbial growth. The latest research, titled “Development of edible food coating using cassava starch/agar blends infused with clove oil for the preservation of mangoes,” published in Sustainable Food Technology (2025), marks the next step in applying these principles to tropical fruits.
The growing global demand for eco-friendly packaging solutions positions Fiji to potentially emerge as a leader in producing biodegradable food wraps, offering a valuable economic opportunity. If commercial production is achieved, Fiji may supply sustainable packaging to eco-conscious markets across Asia, Europe, and the Americas.
“This represents not just a scientific milestone but a driver for economic growth and environmental responsibility,” highlighted Rohindra. The project holds the promise of new jobs, increased exports, and greater recognition for Fiji in the global green innovation landscape.
In a time where the world grapples with plastic waste and food spoilage, Fiji’s cassava-based solution serves as a model for sustainable development. By leveraging local resources and scientific innovation, small island nations like Fiji can play a pivotal role in driving global change. With appropriate investment and policy support, this biodegradable coating could protect both produce and the planet, exemplifying a hopeful vision for a sustainable future.
