Characterization and Molecular Profiling of Biodiesel Produced from African Star Apple Seed Oil Using Ethanol: Supporting Dataset

This dataset contains the supporting experimental and analytical data for the study “Characterization and Molecular Profiling of Biodiesel Produced from African Star Apple Seed Oil Using Ethanol.” The study investigated the conversion of African star apple (Chrysophyllum albidum) seed oil into an ethanol-derived biodiesel fraction through acid esterification followed by alkaline transesterification. The dataset includes the measured mass recovery and physicochemical characteristics of the recovered biodiesel fraction, together with FTIR spectroscopic data and GC–MS molecular profiling data. The FTIR dataset contains the raw spectrum, instrument conditions, and spectral peak information used to establish the functional-group profile. The GC–MS dataset contains chromatographic data, mass-spectral library results, instrument conditions, and the complete 34-peak molecular profile. The dataset also includes the associated analytical figures, raw instrument reports and files, data dictionary, and documentation describing data provenance and processing. GC–MS peak areas are reported as relative chromatographic abundance and should not be interpreted as quantitative mass percentages or absolute fatty acid ethyl ester concentrations. The dataset is intended to support transparency, reproducibility, and further evaluation of the physicochemical, spectroscopic, and molecular characteristics of ethanol-derived biodiesel produced from African star apple seed oil.
