A straight dough method was used for bread preparation.
The following ingredients (g/100g flour basis) were used: water (calculated to obtain a doughLab absorption value of 500FU), instant dry yeast (1g/100g), ascorbic acid (0.01g/100g) and salt (1.8g/100g).
Water temperature was calculated to achieve a dough temperature of 23ºC.
Wheat flour was replaced with extruded wheat flours to a proportion of 5g per 100g flour.
Control bread with no extruded flour was also prepared.
After mixing all the ingredients for 15 minutes using a double-arm kneader AB-20 (Salva, Lezo, Spain), the bread dough was divided into 300g portions, hand- rounded, mechanically moulded, and proofed for 90 min at 30ºC and 75% RH.
The breads were baked in an electric oven for 30 min at 200ºC.
After baking, the loaves were left to cool for 20 minutes, and then weighed.
They were then placed in polyethylene bags and stored at 20ºC until
analysis. All the samples were prepared in duplicate.
