Pequi Kernel oil extraction by hydraulic pressing and its characterization

et al. 2020

The seed by-products of pequi pulp processing have a kernel in its core which is not used due to the difficulty of its extraction from the spinous endocarp. However, this kernel has high quality oil which can be used for human consumption. Thus, the kernel and the oil composition as well as the conditions to obtain the kernel oil by hydraulic pressing were evaluated in this study. The kernel showed high lipid content (55.76%), therefore being a good source for obtaining oil. The oil extraction by hydraulic pressing presented a higher yield at 5.5 tons to 6.0 tons of force and 9% to 10% moisture. Oil recovery was 75%. The pequi kernel oil showed low acid (0.17 mg KOH/g) and peroxide (1.22 mEq O2/kg) values. The kernel oil also presented high levels of oleic acid (42.47%). The results indicate that the kernel oil extraction is an alternative form for using seeds to increase the producer/processor income and to decrease residue volumes in the pequi processing industry.
