The dough was divided into 160 g loaves and manually molded, and the loaves were proofed in pans. Influence of temperature and of starter culture on biochemical characteristics and the aromatic compounds evolution on type II sourdough and wheat bread. Single Junction Reference, Electrode(s) (aka probe or sensor) (if not integrated or included with meter), Electrode fill solution (for re-fillable electrodes), Rinse the electrode with distilled water (a 250mL to 500mL beaker and laboratory wash bottle are ideal), Fill a 50mL or 100mL glass beaker with enough cleaning solution to completely cover the electrode tip and junction, If contaminants remain, use a soft tissue (KimWipes® are ideal) soaked in the cleaning solution, and dab—never wipe—the electrode, Soak the cleaned electrode in storage solution for at least an hour before taking measurements, Repeat cleaning procedure after measurement and always keep hydrated in storage solution, Never wipe the pH electrode with a cloth or any other type of rough material. The decrease in the eGI values in the wheat bread samples obtained by applying the type-1 and type-2 fermentation methods was less than in the whole wheat bread samples.

As shown in the literature, in vitro starch digestion and in vivo blood glucose levels in healthy individuals both decreased significantly after consumption of sourdough bread compared with control bread [, When evaluating the eGI values of the type-1 sourdough bread samples, it was clear that the values were not only related to RS but also changed according to the content of the RDS and SDS fractions. As shown in, In the type-2 fermentation method, the LAB content of the dough at 0 h ranged from 8.74 to 9.28 log CFU/g. The authors declare no conflict of interest. Built in Portland, Oregon by. Similar to the wheat bread, type-1 and type-2 fermentation significantly increased the hardness and chewiness values and significantly decreased the springiness, cohesiveness, and resilience values of whole wheat bread.

If lower than 1 cm (½”) from the top, top off with fill solution, For refillable electrodes: Lower the rubber sleeve that covers the fill hole, or unscrew the fill-hole screw (this allows for faster readings), Prepare beakers: Use separate beakers for each buffer solution (50mL or 100mL are ideal) and a dedicated beaker for rinsing (a 250mL to 500mL beaker is ideal), Fill the two small beakers with the buffer solutions necessary to bracket your intended measurements; for most food applications, this will be 4.01 and 7.01 buffer solutions. Besides the effects of different fractions of starch on eGI, the main role in the reduction of the glycemic index may be due to the presence of organic acids [, Sourdough was found to be a helpful agent for regulating the digestibility of starch and, consequently, reducing eGI in bread products. ; et al.
