Effect Of Particle Size On Oil Yield Using Scent Bean Seed (‘Ozaki’)


This project was done to extract and characterize bean oil according to their particle sizes. The experiment was carried out using scent bean (i.e. ‘Ozaki’, ‘Ijilizi’or ‘Azamu’) as sample. The oils were extracted by solvent extraction /leaching extraction using n-hexane. Proximate analysis was carried out to obtain percentage moisture content, ash content, total oil content, protein content and carbohydrate content of the extracted oils. From observation, it was noticed that as the diameter of the sieve decreased, the quantity of oil obtained increased
