• W4221104292 abstract "As palmeiras são recursos vegetais de grande importância econômica e social no Brasil. Apesar da diversidade e amplo uso são pouco estudadas, havendo necessidade de mais pesquisas, principalmente, sobre a qualidade e composição de espécies ainda pouco exploradas. O trabalho objetivou caracterizar os óleos fixos extraídos do mesocarpo dos frutos de tucumã-açú e tucumã para identificar usos potenciais. Óleos fixos foram obtidos da Amazon Oil Industry LTDA, Ananindeua/PA, sob extração por prensagem a frio. Os tucumãs apresentaram diferenças em todas as propriedades físico-químicas avaliadas, com exceção do índice de peróxidos. Os óleos apresentaram elevado potencial em termos de constituintes bioativos, com destaque para o teor de clorofila total do óleo de tucumã (50,99 mg/100 g) e polifenóis extraíveis totais do óleo de tucumã (147,02 mg/100 g). Em relação ao perfil de ácidos graxos, o óleo de tucumã-açú apresentou elevado conteúdo de ácidos graxos insaturados, principalmente oleico e linoleico, com mais de 73%. Por ser fonte de compostos bioativos, há perspectivas de uso destes óleos como matérias-primas importantes para utilização em escala industrial e comercial, mas a qualidade destes óleos também implica num fator de relevância para o mercado consumidor, evidenciando necessidade de mais estudos.

Potential for use of fixed tucumãs oils ABSTRACT: Palm trees are plant resources of great economic and social importance in Brazil. Despite their diversity and wide use, they are little studied, requiring more research, mainly on the quality and composition of species that are still underexplored. The work aimed to characterize the fixed oils extracted from the mesocarp of tucumã-açú and tucumã fruits to identify potential uses. Fixed oils were obtained from Amazon Oil Industry LTDA, Ananindeua/PA, under cold pressing extraction. Tucumãs showed differences in all physicochemical properties evaluated, with the exception of the peroxide index. The oils showed high potential in terms of bioactive constituents, especially the total chlorophyll content of tucumã oil (50.99 mg/100 g) and total extractable polyphenols from tucumã oil (147.02 mg/100 g). Regarding the fatty acid profile, tucumã-açú oil had a high content of unsaturated fatty acids, mainly oleic and linoleic, with more than 73%. As a source of bioactive compounds, there are prospects for the use of these oils as important raw materials for use on an industrial and commercial scale, but the quality of these oils also implies a factor of relevance for the consumer market, evidencing the need for further studies.
