Abstract

Abstract This research was carried out to evaluate centesimal [dry matter (DM), ash, and crude contents of proteins (CP), fats (CFt) and fiber (CFb)] and mineral composition (Ca, Mg, N, P, K, Fe, Zn, Cu and Mn) of peel and flesh tissues of feijoa fruit (cultivars Alcântara, Mattos, Helena and Nonante, and accession 2316). The genotypes had, in the flesh, DM of 12.10-15.40%, ash of 0.33-0.40%, CP of 0.95-1.45%, CFt of 0.56-1.72%, and CFb of 1.39-2.43%, and in the peel DM of 12.8-17.27%, ash of 0.30-1.49%, CP of 0.56-0.88%, CFt of 0.57-0.90%, and CFb of 2.54-3.98%. The contents of Ca, Mg, K, N and P in the peel were 96-116, 20-30, 1588-3635, 1096-1643 and 68-83 mg kg-1 FW, respectively, and in the flesh were 56-92, 17-29, 1358-2917, 2017-3384 and 255-374 mg kg-1 FW, respectively. Among the micronutrients, Fe had the highest content in peel and flesh tissues (~3.5 mg kg-1 FW). The results show that feijoa fruit represent a dietary source of CP, CFt and CFb, as well as of minerals, especially of P and N in the flesh, and of K and Fe in the peel and flesh tissues.

Highlights

Materials and methodsThe daily consumption of fruits helps in the prevention of many diseases due to their nutritional and therapeutic value (SOERJOMATARAM et al, 2010)
The ash content was different between genotypes only in the skin, with values varying from 0.30% (‘Nonante’) to 1.49% (‘Helena’), while the flesh had average ash content of 0.38% (Table 1)
Our results show that the fruit of superior Brazilian genotypes of feijoa represent an important source of essential elements

Summary

Introduction

Materials and methodsThe daily consumption of fruits helps in the prevention of many diseases due to their nutritional and therapeutic value (SOERJOMATARAM et al, 2010). This study characterizes the centesimal and mineral composition of the skin and flesh tissues of the fruit in superior Brazilian genotypes of feijoa.
