Data are expressed as mean ± SD (n = 50). Means followed by different superscript letters indicate significant differences between the groups in the same row (p < 0.05). Repeated superscript letters indicate that the means were not significantly different (p > 0.05). F1 (100% RRF), F2 (75% RRF:25% CF), F3 (50% RRF:50% CF), F4 (25% RRF:75% CF), F5 (100% CF). CF: cassava flour; RRF: red rice flour.
