Whey is obtained from dairy industries. It is generally disposed into sewage which creates major
problem of pollution besides the loss of valuable nutrients. The process of whey utilization involves higher
processing cost. Therefore, the aim of the present work was to develop low cost nutritious whey beverage for
hard working group of people. Instant energy Ready To Serve (RTS) whey beverage was prepared by
hydrolyzing lactose with immobilized β-galactosidase enzyme, isolated from yeast culture Kluyveromyces
marxianus. Sensory attributes, appearance, taste, aroma, overall acceptability and viscosity were the quality
control parameters employed for beverage evaluation. Mango pulp concentration, stabilizer and sucrose added
in beverage were optimized by the utilization of Response Surface Methodology (RSM). Based on contour plots
and variance analysis, optimum values for mango pulp, stabilizer and sucrose were found to be 17.72, 0.17 and
12.0% respectively. The final product exhibited viscosity 1.753 cp. The energy value of prepared beverage was
322±3.08 KJ per 100 mL of product. The electrolyte composition was also found to be almost similar to the
desired level.
Key words: Hydrolyzed lactose beverage, instant energy beverage, mango fortified whey, RTS whey beverage, sports drink, value added product,
