Sweet whey powder is made by drying fresh whey, the liquid byproduct of the cheese-making process, according to the U.S. Dry Export Council. Commonly used commercially in the production of dairy, bakery, confectionery and snack foods, sweet whey powder is an inexpensive way to add dairy solids to a food product. The powder is a good source of calories from carbohydrates and proteins and is relatively low in fats.
