Uses of Whey

Whey is a yellow-colored liquid left over after curdled milk has been strained. Whey contains high levels of lactose, vitamins, minerals and proteins. Additionally, it contains trace amounts of fat. Whey is available in both powdered and liquid forms for use in several different types of food preparation. According to Charles Onwulata and Peter Huth, authors of "Whey Processing, Functionality and Health Benefits," athletes commonly favor foods made from whey as a source of proteins, vitamins and minerals.

Cheese

• Whey is a key ingredient in several types of cheese, such as ricotta and brown cheese. According to Pat Davis, author of "Benefits of Whey Protein," cheeses that utilize whey have a different consistency and flavor from those that do not contain whey. Liquid whey is most common in cheese production.

Baking

• Liquid whey can replace water in food recipes, adding more nutrients to the final product. Several recipes are tailored specifically to utilize whey, producing healthful foods. Bread recipes often use whey in place of water, according to Davis.

Drinks and Shakes

• Both powdered and liquid whey are mixed into drinks and shakes to add higher protein content. Fruity shakes utilize whey because the strong, sweet flavor best melds with the slight bitterness of whey.

Butter

• Whey cream, or butter, is produced from skimmed whey. Whey cream has a slight salty, bitter taste that infuses foods with a rich flavor. According to Christopher Vasey, author of "The Whey Prescription," whey cream is best incorporated into foods meant to have a strong, buttery flavor as it can overpower other ingredients.

Bath Water

• Bath water with the addition of whey will leave your skin feeling soft and smooth. The skin absorbs the proteins and vitamins of whey, acting as a treatment for dry, itchy skin and sunburns.
