What it is

Whey is a byproduct of cheesemaking, consisting of the liquid remaining after milk has been curdled and strained. Deproteinized whey has had most of its protein removed, leaving behind lactose, minerals, and water. It is often further processed into a powder.

Why it's used

Whey and deproteinized whey are used as ingredients to add a mild, milky flavor and to improve texture in a variety of foods. They can act as a sweetener and contribute to browning in baked goods. They are commonly found in snacks like chips and cheese puffs, as well as in baked goods and confectionery.

Health notes

Whey and deproteinized whey are generally recognized as safe (GRAS) by the FDA for use in food. They are a source of lactose and minerals. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated whey and its derivatives. Evidence does not suggest adverse health effects from typical consumption levels.

Allergen info

Whey is derived from milk, which is one of the 9 FDA major allergens. It does not contain gluten.
