    The replacement of double toned milk with whey at various levels such as 20, 30 and 40 %, respectively was tried and results revealed that 30 % whey replacement was found to be optimum. Optimization of sugar: stevia ratio were tried at 50:50, 25:75 and 0:100 and results revealed that 0:100 ratio was better in overall sensory scores. Health beverage was tried with incorporation of almond oil (2, 3 & 4 %), walnut oil (2, 3 & 4 %) and almond and walnut oil blend (1, 2 and 3 %) and among various additions, 2 % almond oil and walnut oil blend was found to be acceptable. Various levels were tried for optimization of tea and coffee decoction, that is, 15, 20 and 25 %. The results revealed that 15 % of tea or coffee decoction showed better sensory scores. The optimized health beverage was concentrated to 31 % TS and spray dried (inlet 180-190 °C and outlet 80-90 °C) to obtain dried ready to use health beverage. The final optimized health beverage were stored at refrigeration temperature in glass bottles and the dried health beverage was packed in plastic pouches storage at ambient temperature. The health beverage packed in glass bottle stored at refrigeration temperature containing tea and coffee had a shelf life of 15 days and 19 days, respectively whereas dried ready to use health beverage stored at room temperature was to be found in good quality without affecting its sensory attributes up to 3 months of storage. The final formulation of health beverage contains 52.9 % double toned milk, 30 % whey, 0.1 % stevia, and 2 % almond and walnut oil blend and 15 % tea/coffee decoction. The formulation of dried ready to use health beverage (dry mix) for domestic purpose can be prepared by dry blending of 66.4 % of double toned milk powder, 16.8 % whey protein concentrate, 0.8 % stevia, 16 % of almond or walnut oil blend and this health beverage can be prepared domestically by blending and addition of tea or coffee decoction at suitable proportion.
