Rabadi, prepared by fermenting pearl millet (Pennisetum typhoideum L.) (PM) flour with buttermilk is a traditional popular beverage of North – Western states of India. A process for PM based Rabadi using fermented whey was attempted. Fermented whey and PM flour was mixed before fermentation and amount of flour, whey and temperature of fermentation were determined using Response Surface Methodology (RSM) with Central Composite Rotatable Design (CCRD). The product developed using 50 g PM flour, 660 ml fermented whey incubated at 37.5 °C temperature gave the most acceptable product on the basis of sensory evaluation. The standardized product was packed in indigenous pouches and stored at 4 °C and 10 °C. The shelf life of the product was 8 days at 4 °C and 5 days at 10 °C respectively.
