Contenido de ácidos grasos en cuatro poblaciones de pejibaye, Bactris gasipaes (Palmae)
Cooked and uncooked samples from four pejibaye palm races were analyzed to detenrune the moisture content, ether extract and the content of six fatty acids (C16:0 to C18:3). There was an increase in moisture and a decrease in ether extract (p<0.05) in the cooked samples in comparison with the uncooked ones. No significant differences were found in fatty acid content between cooked an uncooked samples, but there were differences (p<0.05) among races conceming the content of four fatty acids. Pejibaye fat is mainly mono-unsaturated (45.6%) and has a low poly-unsaturated to saturated fatty acid ratio (0.5). The fatty acid profile of uncooked pejibaye samples was: oleic acid, 32.6 to 47.8 %; palmitic acid, 30.5 to 40.3 %; linoleic acid, 11.2 to 21.1 %; palmiloleic acid, 5.7 lo 7.1 %; linolenic acid, 1.5 lo 5.5 %; and stearic acid, 1.7 to 2.4 %.
