Grade A Whey

Grade A whey is the liquid byproduct of cheesemaking. It is separated from the solid curds and then processed, often by drying, to create a powder. It is a source of protein and lactose.

Whey is used in a variety of foods for its nutritional content and functional properties. It can act as a sweetener, emulsifier, and texturizer in products like ice cream, baked goods, and processed meats. It is also added to protein supplements and infant formulas.

Whey is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of high-quality protein, which is important for muscle building and repair. International bodies like JECFA have evaluated whey, but no specific numeric limits are typically set for its use as a food ingredient. Evidence does not suggest adverse health effects from consuming whey at typical dietary levels.
