Characterization of oil solvent extracted from four Mango (Mangifera indica L.) kernels

The present study investigates the extraction and potential uses of mango kernel oil using a Soxhlet extractor with n-hexane as a solvent from four different varieties of mango (Bush, Dusha, Kent, and Peter). The oil yield, phytochemical screening and quantifications, and fatty acid profiling of extracted oils were determined. The highest oil yields obtained from Bush (17.10%) and Kent (17.80%) indicated the extent of high oil content in the mango varieties tested in this study. The oils comprise different bioactive compounds, and Dusha has shown significant phytochemical and physicochemical characteristics. Kent has the highest iodine value out of all samples, making it unsaturated and prone to easier oxidation. Since the oils have different fatty acid profiles, Dusha would be better for heart-healthy diets and cooking, while Kent would be better for nutritional purposes. Most of the tested attributes differed significantly (p < 0.05) across the selected varieties. Based on the results of this study, the mango kernel oils from the examined varieties are promising sources of valuable components for the production of nutraceuticals due to their potent antioxidant properties and favourable profile of oleic fatty acids. The study also emphasises the importance of selecting the right mango variety and optimising extraction techniques for sustainable utilisation of mango seed waste.
