3.1. Sensory analysis
The results of hedonic tests on different types of bread are given
in Table 1. The colour of crumb of the enriched bread was much
darker (green) than the control bread what had a slight but a significant
and negative influence on bread acceptability. The taste,
aroma and overall acceptability of bread at substitution levels of
1e2 g/100 g did not differ significantly in respect to control breads.
Higher levels of QL addition, especially 5 g/100 g caused an unpleasant
aroma and taste. Quinoa leaves addition up to 3 g/100 g
had no statistically significant influence on bread texture. Higher
levels of QL addition had negative influence of this parameter. The
sensory characteristics linking results indicated that a partial
replacement of wheat flour in bread with up to 3 g/100 g QL powder
gives satisfactory overall consumer acceptability. However, breads
containing 4 g/100 g and 5 g/100 g of QL were rated comparatively
lower, which might be due to excessive amounts of ground leaves
which negatively affected the aroma, taste, and texture of breads.
