5. Conclusion
Low color distance (Δ E) between both crumbs showed that observers normally cannot see differences between
the crumbs. Significant softer texture of crustless crumb indicates that major differences between both bread
types are different in texture and not in different flavor.
Sensory comparison of the crumb of crustless breads and breads with crust indicated in this study a similarity of
both crumbs. Because many panelists guessed differing sample or recognized differing sample due to different
texture, it is assumed that there was no sensory noticeable diffusion of flavor substances from crust to crumb in
bread with crust. This data indicates that the generally accepted and taughed assumption that the flavor of crust
diffuses into the crumb of bread is, at least for rye-breads, not detectable by sensory tests.
