The results of the proximate analyses carried out on the bread samples are presented in Table 2. The substitution of 10% BPF for CWF in bread caused an increase in the moisture content. This result is due to the increased water content in the dough of the B10BPF, B10BPFXG and B10BPFCMC formulations. The hydrophilic chains in the dietary fibre of BPF have higher water absorption capacities than wheat flour; therefore, it is necessary to increase the water level during composite flour mixing. The BCtr had significantly lower ash content than the other samples. This result may be associated with the presence of a greater ash content in the BPF than in the CWF (3.03% and 0.55% for BPF and CWF, respectively) (Abdul Aziz et al., 2011 and Zanoni and Peri, 1993). In addition, the high ash content of BPF is correlated with the presence of a high mineral content. The banana pseudo-stem has an abundant mineral composition, as previously reported by several researchers (Cordeiro et al., 2004 and Mukhopadhyay et al., 2008). Moreover, the bread samples with the addition of XG or CMC revealed greater ash contents than the B10BPF.
