RESUMO: Na Amazonia sao encontradas especies cujos frutos apresentam quantidade de oleo com valor economico para diferentes aplicacoes industriais. Este trabalho teve o objetivo de avaliar o potencial de producao de oleo do tucuma (Astrocaryum aculeatum) para a producao de biodiesel em diferentes areas do Estado do Acre. As variaveis avaliadas para a caracterizacao foram: producao, quantidade de polpa epicarpo+mesocarpo), castanha (endocarpo), amendoas (semente do interior do endocarpo), teores de lipidios totais na amendoa e na polpa e os atributos quimicos do solo. O teor de lipidios na amendoa foi de 21,9%, enquanto na polpa foi de 31,9%. Apesar da diversidade genetica, o tucuma e uma especie que possui boa produtividade em oleo, mesmo em solos acidos e com baixa fertilidade, apresentando potencial para ser utilizado como uma fonte adicional de renda pelas comunidades amazonidas. ABSTRACT: In the Amazon region species are found whose fruits have quantities of oil with economic value for various industrial applications. This study had the objective to evaluate the potential of oils extracted from tucuma palm fruit (Astrocaryum aculeatum) found in different areas of the Acre State. The yield, amount of pulp (mesocarp + epicarp), seed (endocarp), kernel (seed inside the endocarp), total lipid (almond and the pulp), and chemical soil properties were evaluated. The content of lipids in kernel was 21.9%, while the pulp was 31.9%. Despite the genetic diversity, the tucuma palm fruit is a species that has good bio-oil yield, even in acid soils with low fertility , with potential to be used as an additional source of income for communities in the Amazon region.
