2.6. Data treatment
Response surface methodology was used to analyze the technological
characteristics of the loaves with chia flour and chia seeds
substituted for a portion of the wheat flour and with reduced
amounts of hydrogenated vegetable fat. The Statistica 5.0 program
was used to perform an analysis of variance (ANOVA), to obtain
mathematical models and to build contour curves (p < 0.05). The
data were compared using an analysis of variance (ANOVA) and the
average values obtained were compared using Tukey's test, with
statistical significance (a) set at p < 0.05.
