Physico-chemical characterization and biometry of fruits of ‘pequi’ in western bahia

Abstract

In Cerrado, there are numerous native fruit species with potential for use in traditional systems of agricultural production. In this context, the ‘pequi’ stands out in this biome by its great economic value in Central Brazil. Therefore, this work aimed to study the physical and physico-chemical characterization of Pequi fruits in the Western Region of Bahia. Three hundred fruits were sampled from ten matrices which were collected in an area of the municipality of Angical, BA and conducted to the Seed Laboratory of the State University of Bahia - UNEB. For physical evaluations, the fruit weight; longitudinal and transversal diameters of the fruit; total weight of seeds per fruit; pulp weight, peel weight and pulp yield were considered. As for the physico-chemical evaluations, the fruit pulp was subjected to the determinations of pH, the soluble solids (SS), titratable acidity (TA) and the relation between soluble solids and titratable acidity. For the variables, longitudinal and transversal diameters, the pulp weight, peel weight, seed weight, fruit weight and pulp yield, the mean were, respectively, 63.49 and 61.29 mm, 12.51, 101.91, 27.48, 114.41 g and 11.17%. However, with regard to pH, SS, AT and SS/AT, means were 5.32, 11.95°Brix, 1.76 and 11.53. The results indicated that there are statistically significant differences between all the physical and physico-chemical variables evaluated.
