2.3. Baking performance test
Baking performance test was conducted using a Rheofermentometer F3 (CHOPIN, France). A portion of 250 g of dough was fermented for 3 h at 28.5 C with 2 kg of weight over it according to the Chopin protocol.
From the test two curves were obtained: the dough development curve by an optical sensor, which shows the variation of dough height as a function of time during fermentation; and the gas production and retention curves by a pressure sensor. The following parameters were obtained from the dough development curve: maximum height (Hm), time at maximum height (t1), final height (h) and the weakening coefficient (W) calculated according to Eq. (1):
W ¼ ðHmhÞ100 (1)
Hm
From the gas curves (production and retention of gas as a function of time), the following parameters were obtained: maximum pressure (Hm0 ), time at maximum pressure (t10 ), time at gas release (tx), total volume of gas produced (Vt), volume of gas retained (Vr) and the retention coefficient (R) calculated as Eq. (2):
Vr
R ¼ 100 (2)
Vt
An additional parameter, adjusted maximum height (Hmadj), was calculated (Eq. (3)) in order to identify the dough development independently from gas production which depends on the yeast activity instead of dough properties:
Hmadj¼ H m Vt0 (3) Vtwherein Vt0 is the total volume of gas obtained from control dough
