Proteins and polar lipids
are thus the main surface active components in DL. They coexist in
DL from non-defatted dough and affect each other’s foaming
properties (Kinsella,1981; Mills et al., 2003). Differences in foaming
properties also result from different lipid levels and different lipidto-
protein ratios of the DL samples. To investigate the impact of
only proteins on DL foaming, foaming properties of DL from dough
from defatted flour were also determined.
