Resumen

Palm oil is a food rich in bioactive compounds such as carotenoids, fatty acids, and vitamins; such composition makes it widely used in traditional medicine and culinary applications. In this context, the liquid-liquid extraction of carotenoids from palm oil can help add value to its production chain and increase the availability of natural colorants on the market. Therefore, the present study aimed to extract carotenoids from palm oil at 40, 45, and 50 °C, using low-toxicity mixtures of ethanol + DMSO solvents. The turbidimetric method was applied to obtain experimental data for the ternary systems palm oil + ethanol + DMSO. The Merchuk, Andrews, and Asenjo methodology (1998) was used to obtain the correlations for constructing the binodal curve and tie lines. The carotenoid contents in the extract and refined phases were determined by UV-visible spectrophotometry. The highest recovery of carotenoids was obtained at 45 °C with a total system composition of 20% oil, 30% DMSO, and 50% ethanol. Partition coefficients close to or greater than one were obtained in the carotenoid extraction, indicating good recoverability of the pigments by the extract phase. The stable two-phase systems were formed due to the difference in density and solubility of DMSO and ethanol concerning palm oil. A reduction in the biphasic region was verified as the temperature increased due to increased miscibility between the system components. Thus, it is concluded that adding ethanol to the systems contributed to the solvent mixture having intermediate polarity, with the ability to extract both polar and non-polar carotenoids efficiently.
