Abstract
Of African origin and with an estimated world production of 6.85 million tons, palm kernel oil contributes about 3% of the total world production of oils and fats. With such production, the world waste generation was about 10,026 × 103 tons in 2017, which represents an important environment issue. The present work aimed to review the literature on the main methods of extraction, applications, and future perspectives of Elaeis guineensis Jacq., with emphasis on its seed: palm kernel. Regarding its main applications, biodiesel production was highlighted, since the biomass generated can be used as a substitute for fossil fuels in energy production. Key words: Elaeis guineensis Jacq., palm kernel, extraction of vegetable oils, biodiesel.
Highlights
Palm kernel is an oleaginous seed found in Elaeis guineenses Jacq. fruits
The export growth rate declined a few decades after the Second World War (Atinmo and Bakre, 2003; Corley and Tinker, 2016)
Regarding the destination given to Palm Kernel Cake (PKC), due to its high energy value, is often used as an animal feed supplement (Hossain et al, 2011), and one way to guarantee the maintenance of these nutrients is to make the re-extraction of the residual oil present through supercritical fluid technology, since there is no use of organic solvents in it
Summary
Palm kernel is an oleaginous seed found in Elaeis guineenses Jacq. fruits. Historically, the demand for its grains was much higher than that for oil, due to its high consumption. Palm kernel is an oleaginous seed found in Elaeis guineenses Jacq. The demand for its grains was much higher than that for oil, due to its high consumption. The export of grains increased considerably along with the demand for palm kernel oil, beginning their exports around 1832. The export growth rate declined a few decades after the Second World War (Atinmo and Bakre, 2003; Corley and Tinker, 2016). The palm kernel crop has important socioeconomic.
