increased level of flaxseed that means crumb softness was
increased. This may be due to flaxseed gum and fat content in
flaxseed. The soluble fibre present in the flaxseed attributed a
higher moisture retention in the bread. This could be because of the
fact that the rate of firming has inverse relationship to crumb
softness and also the rate of firming is a function of bread moisture
content i.e. as moisture content increases rate of firmness decreases
(Rogers, Zeleznak, Lai, & Hoseney, 1988).
3.8. Effect of roasted ground flaxseed level on crumb and crust
colour of bread
As the roasted ground flaxseed level increased, there was
decrease in L values and b values of bread crumb observed
(Table 8). Lightness decreased with increased flaxseed level. This
may be due to the original darker colour of flaxseed flour. Our
findings are in accordance of Ahmed (1999) who reported significant
reduction in lightness and increased redness of extruded
snacks prepared from corn and flaxseeds. An increase in a value of
bread crumb was observed with increased flaxseed level. The
difference in redness (a) and yellowness (b) were statistically
significant (p < 0.05) .
In case of bread crust; decrease in L, a, b values with increase in
flaxseed level was observed (Table 8). Similar results were obtained
by Koca and Anil (2007) and Garden (1993) who reported that
ground flaxseed significantly (p < 0.05) reduced bread crust and
