Abstract
This study analyzed the use of the ultrasound-assisted method as an alternative to obtain munguba oil. The extraction provided a 47.70 % yield of an oil with appropriate quality, evaluated by assessing the %FFA as oleic acid, iodine, peroxide, and saponification values, in addition to the refractive index and density. The oil presented thermal stability up to 300 °C, was constituted mainly by palmitic acid (C16:0), and presented a total phenolic content of 55.02 ± 1.872 µgEAG g-1. Results suggest that the ultrasound-assisted method has the potential to obtain vegetable oils without compromising their characteristics and quality, as well as optimize extraction time, solvent volume, and operational costs. Moreover, munguba oil presents itself as a suitable and sustainable alternative as an adjuvant in food products, pharmaceuticals, cosmetics, and biofuels.
