Dough sample preparation
Baking conditions
Determination of bread surface temperature
Determination of bread surface colour development
In order to find the impact of the crust colour variation, twelve dough were prepared with the same weight and baked in 12 identical baking tins and to have the same surface area.
at 180°C for 5, 10, 15, 20, 25 and 30 min. The baking was repeated at baking temperature of 200°C and
220°C.
At each time, the bread sample was removed from the oven and cooled at room temperature before colour test was carried out.
Baking was carried out in two types of electrical oven surfaces which are black surface and shiny surface oven.
