Researchers from Nguyen Tat Thanh University and Nong Lam University Ho Chi Minh City, Vietnam, conducted a review on the potential applications of rambutan (Nephelium lappaceum) peel and seed residues. Rambutan is a widely cultivated tropical fruit in Southeast Asia, and its processing generates substantial amounts of by-products, particularly peels and seeds. These residues are rich in bioactive compounds and have gained attention for their potential use in various industrial applications.
This review summarizes recent developments in the utilization of rambutan peel and seed for environmental remediation, nanotechnology, and the food industry. Rambutan peel contains high levels of phenolic compounds, including ellagic acid, corilagin, and geraniin, while its seeds are a source of lipids and fatty acids. These components enable the transformation of rambutan residues into effective adsorbents and photocatalysts for removing dyes, heavy metals, pesticides, and phenols from water.
Additionally, the bioactive compounds present in rambutan residues facilitate the biosynthesis of nanoparticles, offering potential antibacterial, antioxidant, and anticancer applications. The study also highlights the use of these residues in producing biopolymers, biosensors, and materials for energy storage. The findings suggest that valorizing rambutan waste biomass contributes to environmental sustainability and supports the development of circular economy practices.
