Abstract

Kishk was prepared with two different types of cereals, namely wheat and barley   and free and encapsulated probiotic culture, bifidobacterium lactis BL-12 and stored at 25-30°C for 90 days. To  analyze  the  effect  of  two  different  cereals  on  the  properties  of  kishk,  different  physio-chemical  tests  (protein (total and soluble nitrogen),  fiber,    fat, ash,  acidity, pH  and  moisture)  were  performed.  The results showed that   soluble nitrogen,   ash, acidity and fiber were slightly increased while pH and moisture, total nitrogen values gradually decreased during storage period of 90 days.   Microbiological counts revealed the comparative study of cereal substrates: Wheat and barley showed that encapsulated probiotic culture produced good quality kishk as compared to the corresponding free probiotic culture.
