Abstract
Whey derives from cheese production and is used either in its original form or concentrated in dairy drinks and food products. The whey concentration process generates permeate, which is composed of water and minerals. An alternative for the use of whey permeate is in beverage products. Then, it is important to evaluate its physicochemical properties and sensory aspects of sports drinks formulated with this waste. Different sodium concentrations (0,024, 0,030 and 0,40%) were tested and the intermediate concentration achieved the best results in terms of osmolality in accordance with the standard of current legislation. For the sensory analysis, different concentrations of lemon flavor (0,02, 0,04 and 0,06%) were used, all of which differed significantly (p<0,05) from the commercial sports drink, but the 0,02% concentration had the smallest difference (1,47). The present findings demonstrate the potential of use of whey permeate obtained from nanofiltration for the formulation of sports drinks.
