DETERMINATION OF THE FATTY ACID PROFILE IN Eugenia dysenterica DC. SEEDS

Abstract

ABSTRACT-The present research aimed to determine the fatty acid profile in the seed oil of cagaita fruits cultivated in Goiânia, state of Goiás, in 2013 and 2014 harvests. The study was carried out with fruits produced by cagaita trees cultivated in the field of the School of Agronomy, Federal University of Goiás (EA/UFG), Goiânia, GO, where, in 1998, 440 cagaita seedlings from different municipalities in Goiás were planted. Fruits were collected from plants with 16 years of age in full production stage. Cagaita seeds show in their fatty acid profile mostly linoleic acid, oleic acid and palmitic acid. There was no variation in fatty acids content present in seeds between years 2013 and 2014, assuming that there are no external influences such as weather, foliar nutrients or soil, in the production of these oils.

Fatty Acid Content and Physicalchemical Properties of Cagaite Seed Oil (Eugenia dysenterica DC) Obtained by Different Extraction Methods

“…The three fatty acids present in higher quantities, C18:2 (linoleic acid), C18:1 (oleic acid) and C16:0 (palmitic acid), were also found by Jorge et al 5 and Camilo et al, 6 but the percentages were different, and factors such as genotype, growth condition, extraction method, among others may be the causes for these diferences. 39 The rate of saturated fatty acids varied from 19.46% (OCP03) to 31.18% (OCS09) while the amount of unsaturated fatty acids ranged from 54.72% (OCP03) to 67.64% (OCS09).…”

“…Jorge et al 5 studied the fatty acid profile of dehydrated and crushed seeds of cagaite using ethyl alcohol as an extractor, obtaining 37.66% of saturated fatty acids and 62.34% of unsaturated fatty acids. Camilo et al 6 carried out an investigation of the variation of the fatty acid components of the cagaite seed oil, gathering 440 samples of different plant seedlings and obtained oils with 27% of saturated fatty acids and 73% of unsaturated acids, with no significant variation between the analyzed samples.…”

“…The fatty acids in greater quantity were oleic acid and linoleic acid. Camilo et al 6 carried out an investigation of the variation of the fatty acid components of the cagaite seed oil, gathering 440 samples of different plant seedlings and obtaining oils with 27% of saturated fatty acids and 73% of unsaturated acids for the samples analyzed.…”

Biodiesel production from cagaite seeds (Eugenia dysentericaDC) oil: An alternative for biofuel production

“…Cagaite ( Eugenia dysenterica DC.) seed oil contains high polyunsaturated fatty acid content, particularly linoleic acid (10.5%) and linolenic acid (11.86%), surpassing the levels found in soybeans, which currently serve as a major source for biodiesel production in Brazil 21–23 . Traditionally, cagaite fruit is utilized in regional cuisine for the preparation of sweets, jellies, and other derivatives.…”

“…seed oil contains high polyunsaturated fatty acid content, particularly linoleic acid (10.5%) and linolenic acid (11.86%), surpassing the levels found in soybeans, which currently serve as a major source for biodiesel production in Brazil. [21][22][23] Traditionally, cagaite fruit is utilized in regional cuisine for the preparation of sweets, jellies, and other derivatives. However, the seeds, which are usually discarded, possess a significant amount of fatty acid, making them a potential feedstock for biodiesel production.…”
