The recommended baking time for the wheat bread was 30 min,
half the wheat bread was baked for an additional 30 min, these
bread turned out burned with a very hard crust indicating a serious
‘‘over-baking’’.
In the wheat and the rye bread, a significant difference
was found between the retention of vitD2 and vitD3. Furthermore,
the retention of vitD3 and vitD2 in rye bread of 69% and 73%,
respectively, was significantly different from the retention of 85%and 89% in wheat bread baked for 30 min. The final temperature
measured (104 C) inside the wheat bread baked for 60 min at approx.
170 C was significantly higher than inside the rye bread
(90 C) baked for 60 min at approx. 186 C.
