crumb colour values due to the possibility of maillard reaction due
to proteins and phenolic compounds in flaxseed.
3.9. Effect of RGF level on bread quality characteristics
The bread loaf volume and specific volume were the parameters
used for measuring bread quality. Table 7 inferences that the volume
of loaf was not much affected when 5(g/100 g) flaxseed was
substituted in the bread. However, beyond 5(g/100 g) there was
significant (p < 0.05) decrease in bread loaf volume was observed.
This may be due to the dilution of gluten and interference of lignans
and dietary fibres in the gluten network (Wang, Rosell, & Benedito
de Barber, 2002).
4. Conclusions
The present study on effect of flaxseed flour addition on physicochemical
and sensory properties of functional bread has established
some new findings. Significant increase in water absorption
was observed with increased flaxseed level. Dough stickiness was
increased significantly upto 10(g/100 g) flaxseed levels. Softness of
bread crumb increased with increased flaxseed level. Darkness of
bread crust and crumb were increased significantly with increased
flaxseed level. Loaf volume and specific volume of flaxseed flour
substituted bread were affected by flaxseed. Flaxseed flour
substituted breads showed higher moisture, ash, fat and protein
and dietary fibre. The standardized bread was acceptable up to
10(g/100 g) roasted ground flaxseed level based on sensory attributes
of bread.
