From the results of this present study, we can conclude that the
sweet bakery product (Kougelhopf) obtained by frozen doughs
showed a lower specific volume substantially compared to fresh
one. This decrease is widely observed for high freezing rate (liquid
nitrogen). However, the specific volume of Kougelhopf obtained
from frozen DY dough was stayed constant compared to the control
(DY fresh Kougelhopf) despite freezing. The study confirmed
that yeast amount compensates the loss of the yeast activity during
freezing.
