Abstract

During storage several factors influence jatropha (Jatropha curcas L.) seed quality, with consequent effect on oil quality, mainly by increasing acidity due to oxidation and hydrolysis reactions. For biodiesel synthesis, high acidity is undesirable, because the formation of saponaceous material hinders separation of biodiesel from excess alcohol and glycerol, resulting in the formation of emulsions. Therefore, it is important to know the effects of storage conditions on the quality of grains, oil and biodiesel, in order to develop storage technology for these products, suitable for family farming or for the industry. Therefore, this study was done to evaluate the physical properties of seeds and oil chemistry during storage. The evaluations were done in the beginning and the end of the storage period. The results showed that the deterioration of jatropha seeds during storage was more pronounced at temperatures of 25oC or higher.
