Fatty acid ethyl ester from Manilkara zapota seed oil: a completely renewable biofuel for sustainable development

This article reports the deliverables of experimental study on production a completely renewable biofuel from Manilkara zapota fruit and seed oil. It was attempted to synthesis ethyl ester oil using bioethanol synthesized decayed fruit. Bioethanol produced through fermentation fruit, waste skin, pulp with Saccharomyces cerevisiae then distilled at 72°C. The yield noted as 10.45% (v/w). 95.09% pure 4.9% water molecules were present in sample. Mechanically extracted raw used for conversion. molar ratio oil, quantity KOH, process temperature investigated maximum ester. A 9:1 1.5% (w/w) 70°C identified enhanced ethanolysis parameters. 93.1%. Physicochemical characteristics bioethanol, measured per corresponding ASTM standards. found that both Zapota could be promising substitutes fossil diesel gasoline.
