3.3.4. Cake crumb color
Cake crumb brightness and L*a*b* values are listed in Table 4.
Results mimic the previous color results for bread made with heattreated
flours. As temperature and time increase, the brightness
and lightness values decrease. However, only the highest level of
treatment (heat treated sorghum flour at 125 C for 45 min) produced
a cake with a significantly lower (p < 0.05) lightness value
when compared with the control. Despite the slightly darker crumb
color, this defect is negligible in comparison to the positive effects
of heat treatment on overall volume, texture, and crumb structure.
