    Effect of Germination and Fermentation on Microflora, Sensory Characteristics and Energy Density of Fermented Low Tannin Sorghum/Chickpea Blended Porridge as Complementary Food
    (Addis Ababa University, 2013-06) Markos, Tsion; Urga, Kelbessa (PhD)
    NlIIrilional composition, microbiology and sensO/y characteristics oj' germinated and fermented low lannin sorghum (Sorghum bicolor L. Moench) variety ("teshole ") and kabuli chickpea (Cicer arielinum L.,) variety ("harbu ' ) blend were invesligated. Traditional processing (germinat ion and jimnel1lation) methods were observed to be effective in reducing antimllritional facto rs. Siondard Methods o/AOAC were usedfor analysis o/nlltritionol compositions. Porridf!,el lI'ae evaluated/ur their acceptobilitv test using a nine poinl hedonic scale. Tvlal p/ole ('ollnl (lnd IOe/ic acid baclerial cOllnl Irere enumerated using Plate Count Agar and MRS ogCt/; re.sjJectively Fermentation for -18 hours reduced the tOlal baclerial count from \I 57 to 3. 1610gcjil/m by reducing the pH to the level of <-1.5 which inhibited the gruIL th of tolal bacterial count to the level <410gcji.t!ml.
