Abstract

Chemical composition in different parts of banana pulp was determined. Ash and protein mean concentrations in the central part of the pulp were higher than in the medium part, and these were higher than those in the external part. The mean concentrations of the fiber (total and non-soluble) in the central part were higher than those found in the other parts. Ascorbic acid behaved inversely; the mean concentration significantly decreased from the external part to the central part. The central part contained the highest mean concentrations of the analysed minerals (Na, K, Ca, Mg, Fe, Cu, Zn and Mn), with statistically significant differences for Cu, Zn and Ca. A tendency to differentiate the pulp samples of banana as a function of the part considered was observed after using factor analysis. The samples from the central part were different from those from the external part. The samples of the medium part overlapped with those of the other two parts.
