3.3.4. Available carbohydrates
Unprocessed non-germinated barley based food mixture contained
3.02 g/100 g total soluble sugar, 0.95 g/100 g reducing sugar,
2.07 g/100 g non-reducing sugar and 42.92 g/100 g starch,
respectively (Table 4). Autoclaving of the food mixture resulted
in a significant increase in total soluble, reducing and non-reducing
sugar contents and decrease in starch content up to the extent of
19%. Moist heat may cause rupturing of starch granules followed
by hydrolysis of starch to oligosaccharides and then to monosaccharides,
which caused significant increase in concentration of sugars
(Grewal & Jood, 2009). When the autoclaved food mixture was
fermented with L. acidophilus curd, a marked change in the profile
of available carbohydrates was observed. Fermentation of food
mixture reduced the contents of total soluble sugar, non-reducing
sugar and starch by about 24%, 64% and 37%, respectively and these
changes were significant when compared to the carbohydrate profile
of the autoclaved unfermented food mixture. In contrast,
reducing sugars of the autoclaved + fermented food mixture increased
by about 4-fold over the unprocessed food mixture.
