Waste orange seeds (Citrus sinensis seed) transformation, a viable industrial bio-oil: Oil extraction, physicochemical characterization and vital instrumental analyses studies

•Solvent extraction using N-hexane was used for extracting waste Orange seeds (OS) [Citrus sinensis seed] oil.•Physicochemical characteristics of OS indicate its potential application industrially.•The FTIR analysis indicated the prevalent functional groups in the extracted oil.•Gas chromatography-mass spectroscopy (GCMS) analysis indicated the saturated and unsaturated fatty acids present in OS oil.
