Perfil de ácidos graxos de folhas e amêndoas orgânicas de guariroba

Abstract

Syagrus oleracea Becc., species native to Cerrado, can contribute to food security, income generation for farmers and for the preservation of species, due to the multiple products produced by the plant. Due to the lack of studies on the properties and the use of essential oils produced by S. oleracea, the objective of characterizing the fatty acid profile of leaves and kernels guariroba present in organic system. The leaves and the fruits mature, present in the ground, guariroba were collected from plants present in Jandaia-Goiás under organic system. It was determined the following attributes: moisture and volatile material, acidity (% oleic acid), saponification value, lipid content and composition/fatty acid levels. The fatty acids found 12 almonds and 10 in the leaves. The almonds have more saturated fatty acids (87.51%), while the leaves there is a tendency to balance between saturated and unsaturated (57.39%) (42.61%). The acid value of oils (% oleic acid) obtained from almonds and leaves were of 20.94 percent and 2.13 percent respectively. Guariroba oils from leaves and almonds feature distinct composition of fatty acids. The oil of the leaves is composed mainly by oleic acid. Already the oil of almonds is formed primarily by saturated fatty acids, like lauric acid. This difference in composition influences the potential use and possible uses, and therefore represents more income alternatives for farmers.
