The fruit seeds of the Northern Amazon Region were evaluated bromatologically and nutritionally in terms of the level of macro- and micro-elements and fatty acids present in them. Bromatologically, the seeds of camu-camu (369.08 kcal 100 g-1) and biriba (364.78 kcal 100 g-1) have the highest energy value. In terms of the macroelements, the highest concentration was potassium (554.23 mg 100 g-1) seen in graviola, followed by magnesium (123.11 mg 100 g-1) in biriba. In terms of micronutrients, the highest concentrations are zinc (4.14 mg 100 g-1) and manganese (4.12 mg 100 g-1) in abiu seeds. The fatty acids composition of the seeds studied had a higher percentage of unsaturated fatty acids. Among the most saturated is palmitic acid with a concentration of 40.4% for tapereba seeds while among the unsaturated is oleic acid with a concentration of 47.4% for bacupari seeds. Key words: Oleic acid, bromatological, minerals, saturated fatty acids (SFA), unsaturated fatty acids (UFA).
