Whey-Whey Powder Lactose,and Whey Protein Concentrates

Whey is a dilute, highly perishable and largest by-product of dairy world from the manufacture of cheese, casein, chhana, paneer, chakka and co-precipitates. The continuing annual growth in the consumption and production of the cheese and coagulated milk products represents the generation of extremely large additional quantities of whey because of the huge base. The projections for current world production of whey are about 125 million tonnes. About 68% of it is produced in European countries and about 24% in North America. Cheese whey accounts for nearly 95% of total whey. In India, the major source of whey is from the production of chhana and paneer. In the absence of systematic surveys/statistics, the predicted

value for whey production is estimated at 5 million tonnes per annum. In view of the low solids content of whey, there has been a gross lack of interest in its utilisation compared to other fluid by-products of dairy industry. Due to the presence of high organic matter (6-7% total solids) in the form of protein, lactose, fat minerals and water-soluble vitamins, its disposal causes environmental pollution.
