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.
