Caracterização de frutos de socoró (Eugenia brachypoda D.C.) de ocorrência natural, no Sul do Amazonas

Abstract

The socoró (Eugenia brachypoda) belongs to the family Myrtaceae, has a natural occurrence in the Amazon region, where it is shrub-shaped, in flood areas, along riverbanks, lakes, várzeas and igapós. Such fruit may present unevenness in the analyzed aspects, due to being of native origin. The fruits were harvested on the banks of the Paraizinho lake, located on the right bank of the Madeira River, in a community near the municipality of Humaitá, in the state of Amazonas. The objective of this study was to perform the physical and physico-chemical characterization of fruits from the natural occurrence of socoró, as well as to evaluate their fitness and quality according to the genotypes, where the evaluations were carried out at the Federal University of Amazonas, Campus-Humaitá. Using a completely randomized statistical design, the following variables were evaluated: fresh weight, longitudinal and transverse length, longitudinal / transverse length ratio, yield, percentage of bark, seeds and fruit shape. The physico-chemical characterization: pH, soluble solids, titratable acidity and soluble solids / titratable acidity ratio. Observing results of fresh fruit, showing lower values when compared to camu-camu, fruit used to compare the parameters. For the SS / AT ratio, it presented moderate values, due to the titratable acidity being low, showing that the fruit can have a pleasant flavor in relation to the sweetness. However, it presents pH values with low acidity, which can interfere in the conservation of this fruit.
