2.1. Fats, oils, and blend preparations
The murumuru fat, bacuri fat, pracaxi oil, tucuma kernel oil, patawa oil, and Brazil nut oil used in this study were kindly supplied by Amazon Oil Industry (Ananindeua, Brazil). The developed blends were based on the study described by Bezerra, Rodrigues, de Oliveira, da Silva, and da Silva (2017). Thus, binary blends (fat + oil) of murumuru fat + pracaxi oil, tucuma kernel oil + patawa oil and bacuri fat + Brazil nut oil were prepared at 50:50, 60:40, 70:30, 80:20 and 90:10 (w/w) ratios, using an analytical balance (XT220A, Precisa, Switzerland, precision of 2×10-4 g). Experimental measurements were performed in triplicates and presented alongside their standard deviations.
