Abstract: Interest in biodiesel as an alternate fuel for diesel engines has increased in recent years. An important consideration in selection of feedstock for biodiesel production is the content of free fatty acid (FFA) in the oil. However, the FFA is affected by the storage duration and condition of the feedstock before extraction. This paper investigates the effect of storage period of Jatropha seeds on the oil yield and FFA content of the extracted oil. The study was carried out for a period of four (4) months. The FFA content and seed oil yield was determined before storage as control and regularly at monthly intervals. 50g of seed samples at an initial moisture content of 6.39% wb stored at room temperature and milled using a grinding machine to a particle size of 0.5mm. The Soxhlet extractor was used to extract the oil using petroleum ether as solvent. At average marginal moisture increase of 0.1% over the storage period, oil yield decreased significantly from 35.57% to 31.1%. Conversely, the FFA content (%) which is one of the critical parameters in the biodiesel production process also increased from 7.83% to 32.1%. The study concludes that, storage duration and improper handling of Jatropha seeds during storage have an effect on the quality viz. FFA content of the extracted crude oil for biodiesel production.
