2.2. Thawing, proofing and baking
For baking the dough, samples were withdrawn from the freezer; 12 samples were put on one tray with baking paper and covered with plastic. They were thawed 75 min at ambient
temperature (21-23C).
Thereafter, they were put into a proofing chamber and proofed for 50 min at 35 C and 75% RH.
Afterwards,the samples were baked for 10 min at 190C in an air oven.
The trays were automatically rotated horizontally during the baking time.
When only a few samples were baked, the oven was filled with additional dough pieces to simulate a full oven with equal baking conditions. After baking, all samples were taken off the tray,put on a wooden table and cooled for 1 h at room temperature and for another hour at a controlled temperature of 23C and 50% RH.
For N and Fi the same procedure was used
