Whey is the aqueous (serum) protein of the milk. It compromises approximately 20% of the protein in milk, albumins and globulins, majority of lactose and the water soluble nutrients. The disposal of whey, the liquid remaining after the separation of milk fat and casein from the whole milk, is a major problem for the dairy industries, which demands simple and economic solutions. The usage of whey to valuable products could overcome the issue. Whey-based pineapple beverage was prepared by blending Pineapple juice with whey in different proportions such as 10:90, 20:80, 30:70, 40:60, 50:50 and 100 ml juice as control, 3 g of sugar were fixed per 100 ml of the beverage and analyzed for various physic- chemical and sensory characteristics for its overall acceptability. Acidity and TSS (Total Soluble Solids) content increased while pH decreased during storage. A significant decrease in ascorbic acid content was also observed during storage. The overall acceptability of the beverage was desirable up to 20 days of storage at refrigeration temperature. The study revealed that beverage prepared by blending the whey and Pineapple juice in proportion 30:70 (T3) & sterilized at 850C for 15 min, was found better in almost all physic-chemical, microbial properties and sensory quality parameters as compared to other combination.
