Nutrients in Amazonian fruit pulps with functional and pharmacological interest

In this research, nine fruits cultivated in Northern Amazon were studied: Abiu, acerola, araca, bacupari, biriba, camu-camu, fruta-do-conde, graviola and tapereba, with the objective of carrying out a proximate and nutritional study of the pulps of the Northern Amazon fruits. They were graviola (76.83 ± 0.02 Kcal 100 g-1), bacupari (53.15 ± 0.02 Kcal 100 g-1) and fruta-do-conde (46.66 ± 0.02 Kcal 100 g-1). Among the macronutrients, potassium with high concentration stood out, especially in graviola (541.16 ± 0.24 mg.100 g-1) and biriba (468.21 ± 0.13 mg 100 g-1). Among the micronutrients, iron concentrations was high in araca pulp (3.04 ± 0.02 mg 100 g-1), and abiu was abundant in zinc (3.71 ± 0.02 mg 100 g-1) and manganese (6.61 ± 0.11 mg 100 g-1). The presence of cobalt at the level of traces in some of the pulps studied stood out. The Pearson correlation coefficient was evaluated, as well as the statistical treatment by multivariate analysis Principal Component Analysis (PCA) to establish the correlation between the variables studied. Key words: Amazonian fruit, functional food, nutrients.
