O oleo foi analisado durante 70 dias avaliando as caracteristicas fisico-quimica indice de acidez, indice de refracao, densidade aparente, viscosidade absoluta, indice de peroxidos, oxidacao lipidica pelo metodo de TBARS, parâmetros de cor (L*, a*, b*, C* e h*) e carotenoides (α-caroteno e β-caroteno) a cada 10 dias de armazenamento, alem do sistema β-caroteno/acido linoleico e perfil de acidos graxos. As variaveis se mantiveram estaveis durante os periodos de analises e os carotenoides totais variaram entre 836,91 a 1036,96 µg/g. O acido graxo com maior teor foi o acido oleico com valor de 78,06 g/100 g de acidos graxos e relacao ω6/ω3 de 1,95. O oleo de buriti apresenta qualidade nutricional que justifica o estimulo ao consumo devido aos acidos graxos que apresenta, necessitando dos orgaos reguladores a elaboracao de um protocolo de extracao do oleo da polpa do fruto EnglishThe objective of this research was to evaluate the fatty acid profile and physicochemical properties of buriti oil under storage conditions. The oil was analyzed for 70 days by evaluating the physicochemical characteristics of acidity index, refractive index, bulk density, absolute viscosity, peroxide index, lipid oxidation by TBARS method, color parameters (L *, a *, b *, C * e h *) and carotenoid profile (α-carotene and β-carotene) for every 10 days of storage, in addition to the β-carotene/linoleic acid system and fatty acid profile. Variables remained stable over the analysis periods and the total carotenoids ranged from 836.91 to 1036.96 µg/g. Oleic acid accounted for the highest content among fatty acids, with a value of 78.06 g/100 g of fatty acids and a ω6/ω3 ratio of 1.95. Buriti oil has a nutritional quality and a fatty acid profile that justifies recommendations for its consumption, suggesting the need for regulatory bodies to draw up a standardized protocol for extracting oil from the fruit pulp
