How is whey powder made?
Whey powders and modified whey powders. Whole whey powders containing less than 15% protein are produced by concentrating whey by evaporation alone or in combination with reverse osmosis followed by spray drying. Special methods are used to produce non-hygroscopic, non-caking wettable whey powders.
Why is holding period required for whey powder?
Such a holding period (sometimes also involving seeding) is required to allow for crystallization of the lactose into a nona morphous, nonhygroscopic form prior to drying.
What is a skim milk/whey powder?
Skim milk/whey powder blends are made by replacing a portion of the skim-milk solids by whey-based solids. These replacers can be dry blends of skim-milk powders and whey-based solids or, alternatively, skim milk and whey may be blended prior to heat treatment, concentration, and drying. There are currently no specifications for the composition of these powders which contain a higher ratio of whey protein to casein than conventional milk powders. Blends are formulated to obtain the desired composition and functionality in the target applications, such as confectionery, bakery, icecream, and yogurts. Skim milk/whey powder blends are used as economic alternatives to skim-milk powder in many recombined dairy products. (See WHEY AND WHEY POWDERS | Production and Uses; WHEY AND WHEY POWDERS | Protein Concentrates and Fractions .)
How much whey is evaporated to supersaturate lactose?
Sweet whey is evaporated to 60–70% solids to supersaturate lactose and flash cooled to 30 °C, at which point a-lactose crystals form. Further cooling to 15 °C causes the mutarotation of β -lactose to a-lactose and some 75–80% of the lactose crystallises. The whey concentrate can then be spray-dried.
