Yoghurt as a starter in sourdough fermentation to improve the technological and functional properties of sourdough-wheat bread

نویسندگان

چکیده

The incorporation of yoghurt as a starter in sourdough wheat bread, to improve technological and nutritional properties, was investigated. Two bread dough matrices were considered: endosperm flour blended with whole-grain flour. fermentation’s types performed, two-stage yeast fermentation. Compared dough, yoghurt-sourdough fermentation promoted considerable changes chemical composition, particularly when conjoined flour: higher protein proteolysis degree, increase peptide free amino nitrogen content, solubilization phenolic compounds (46–53%), DPPH radical scavenging (54–65%) ferric-reducing power (85–88%), observed. As baking ingredient, improved the crumb softness (15–12%) delayed staling (40–35%). Nutritionally, glycemic index reduced (18–32%) while digestibility (6–12%) acids bioavailability (50–100%) enhanced. addition techniques offered promising tool bread's functional properties.

Influence of Raisin Starter Syrup Concentrations on the Properties of Sourdough and Sourdough Bread

The present study evaluates the effects of syrup concentrations of natural raisin microflora culture on the characteristics of sourdough and sourdough bread. The original total titratable acidity (TTA) of the starter solutions were between 10.30 and 10.45 mL, after 96 hours of incubation, the TTA of the starter solution increased to 11.30-11.85 mL. The greatest pH decrease and TTA increase occu...
