Electrical technique concentrates milk without using heat, challenging traditional preservation methods

Dehydrating milk to turn it into powder is, today, an energy-intensive process that subjects the product to high temperatures. Powdered milk is widely used by the food industry and allows the product to be stored and transported in a stable condition for long periods of time without the need for refrigeration. While industrial methods are effective, they have high energy costs and can alter heat-sensitive components, such as whey proteins, enzymes or vitamins.
