Samples were considered based on pH, acidity and microbes count. Sensory evaluation was done in fourteenth day. Results showed the maximum activity of bacteria was recorded in fourteenth day so that when this value was increased, the acidity also was being increased. Consistency time of product was determined 21 days and also bacteria indicated significant progress on MRS agar.
