“…Oliveira et al (2012) found similar results when attesting to the efficiency of using ethanol as an extraction solvent for rice bran oil. Some authors, such as Brum, Arruda and Regitano-D'arce (2009); Cerutti et al (2012); Correia (2009); Freitas et al (2010) and Gandhi et al (2003), describe the existence of a series of solvents, mixtures and methods which can be used for extracting oil from grain, however the authors highlight the importance of taking into consideration some stages of the extraction process, such as solvent recovery, and the boiling process. Navarro et al (2007) point out that solvents differ in their extraction capacity according to the difference in polarity; the choice should be made with caution.…”

The soybean has been widely studied due to its constituents and to their application. Authors have pointed out that its composition can vary, with its use frequently taking the form of oil. The oil extraction process, which is in constant application in the market, consists of the use of extraction solvents, with hexane being one of the most used; however the fact that this comes from non-renewable sources has aroused interest in its replacement. As a result, ethanol has been seen as an alternative solvent, despite increasing the cost of the process. This study therefore aims to evaluate the composition of three soybean cultivars planted in the region of Palmas, in the state of Tocantins, Brazil, and to optimise oil extraction from the beans through the use of a binary mixture of ethanol and hexane. The cultivars displayed high protein and lipid potential. The extraction time and temperature proved influential in the process. Ethanol, when present in greater quantity in the mixture, with an increase in temperature, caused an increase in the levels of extracted oil.

ResumoO presente estudo objetivou realizar uma revisão de literatura sobre o desempenho de produção de óleo de palma irrigada, as necessidades edafoclimáticas, os principais métodos de extração de óleo e a importância das cultivares. Com uma produção mundial de óleo estimada de 62,35 milhões de toneladas na safra 2014/2015, a palma de óleo, Elaeis guineensis, se consolida como a cultura maior produtora de óleo no mundo. É originária do Sudeste Africano e foi trazida para o Brasil com os escravos. No Brasil, a palma se adaptou na forma de bosques espontâneos na Bahia e é cultivada em grandes plantios comerciais, principalmente, no estado do Pará. O principal produto obtido é o óleo que possui diversos usos, tais como: utilização na indústria alimentícia, química, cosmética e de combustível. Como a palma de óleo é uma cultura de grande importância, estudos são necessários para aperfeiçoar as técnicas de cultivos e de extração de óleo, principalmente em nível nacional, pois tem grande potencial de produção, porém, ainda não corresponde ao suprimento da demanda interna de óleo de palma.
