Sensory evaluation
The sensory evaluation scores for colour, aroma, softness, gumminess, taste and overall acceptability were obtained from semi-trained panellists and are presented in Fig. 2. The substitution of BPF at the 10% level did not affect all the sensory properties of the bread as compared to the control, with the exception of colour. According to the ANOVA results, the BPF-containing samples exhibited lower scores for colour (4.10–4.33) than the control (5.77). The colour of the bread is an important sensory characteristic for consumers (Hathorn et al., 2008). Consumers perceived breads as either light or dark and have preferences depending on which type the bread appears to be. For example, consumers expect rye bread to have a dark colour and may reject a light-coloured rye bread (Hathorn et al., 2008). Assuming that is the case, consumers may prefer bread with the incorporation of BPF, which would be light in colour.
