Wheat is a main ingredient of the bread, so the suitability of mixed culture of Lb. casei, Lb. brevis and Candida humilis was
determined for different spring wheat cultivars for the preparation of sourdough bread. Four spring wheat cultivars such as
Lasani-2008, Millat-2011, Punjab-2011 and AARI-2011 were analyzed for chemical composition, physical and farinographic
parameters. The cultivars were found significantly (P<0.05) different in physicochemical and farinographic parameters.
Millat-2011 exhibited the highest scores for all these parameters. Breads prepared from these cultivars were analyzed for pH,
titratable acidity, organic acids, and volatile compounds. The sourdough bread prepared was also subjected to analysis of
essential amino acids and various sensory attributes. Sourdough bread produced from Millat-2011 had the highest sensory
scores. Fermentation by LAB improved the flavoring compounds and amino acid profile of the sourdough bread as compared
to yeast leavened bread. The value of lysine improved from 0.16g/100g to 0.39g/100g. Ethanol; 1-propanol, 2-methyl; 1-
butanol; 2-methyl-1-butanol; 3-methyl ethyl acetate; acetaldehyde; acetic acid; 1-hexanol; benzaldehyde; hexanal; N-hexanal
and propanal-2-methyl were found in sourdough bread
