Whey Solids

Whey solids are a byproduct of cheesemaking, consisting of the liquid remaining after milk has been curdled and strained. This liquid, whey, is then processed to remove water and lactose, resulting in a concentrated powder. It is a source of protein and other milk solids.

Whey solids are used as a nutrient source and to improve texture and flavor in a wide range of foods. They can act as a binder, emulsifier, and contribute to browning in baked goods. Common applications include baked goods, snacks, processed meats, and dairy products.

In the U.S., whey solids are generally recognized as safe (GRAS) by the FDA. They are a source of high-quality protein and may contribute to satiety. International bodies like JECFA and EFSA have evaluated whey and its components. Evidence does not suggest adverse health effects at typical dietary intakes.
