Optimization and Characterization of Interspecific Hybrid Crude Palm Oil Unaué HIE OxG Nanoparticles with Vegetable By-Products as Encapsulants

Nanoencapsulation of hybrid crude palm oil Unaué HIE OxG with jackfruit by-products as encapsulants: A study of cellular antioxidant activity and cytotoxicity in Caco-2 cells

Hybrid crude palm oil (HCPO) HIE OxG is notable for its abundance of carotenoids, tocopherols, and tocotrienols. Investigating cellular antioxidant activity (CAA) and the non-cytotoxicity of oil nanoparticles is crucial for understanding the behavior of these phytochemicals in biological systems and ensuring the safety of products. Nanoparticles of HCPO, encapsulated with jackfruit by-products were produced and characterized for CAA and cytotoxicity in Caco-2 cells. The nanoparticles exhibited nanoscale diameters (<250 nm), uniform distribution and stability (polydispersity index < 0.25; zeta potential JSF-NP -12.46 ± 0.15 mV and JAF-NP -13.73 ± 1.28 mV). JSF-NP and JAF-NP demonstrated superior CAA compared to the free HCPO across all concentrations, without inducing cytotoxic effects on differentiated Caco-2 cells. This study underscores the importance of investigating the CAA of edible oil nanoparticles, with non-cytotoxicity indicating biological safety and the potential to safeguard intestinal epithelial cells. Thus, JSF-NP and JAF-NP emerge as promising delivery systems for future HCPO applications.
