In the current scenario of energy crisis, oilseeds stand out among crops due to increased interest in renewable fuels such as biodiesel. The jatropha (Jatropha curcas L.) is one of the most promising oilseeds for being a perennial plant and providing high yield, despite being rough, which guarantees its adaptation to different types of soil and climate. Another jatropha feature that stands out is that its oil is highly toxic and cannot be used in foods, so its production can be intended solely for energy purposes since there has always been competition between the production of food and alternative energy. The use of raw materials originated from oil plants that are intended for human consumption in the generation of biofuels may cause a decrease in food production (Araújo, 2008). However, this subject is controversial and has been widely debated.
