Is there albumin in all dairy products?

No, not all dairy products contain albumin. Albumin is a type of protein that is found in high concentrations in egg whites and blood plasma, but it is not a major component of milk.

The primary proteins found in milk are casein and whey protein. Casein makes up about 80% of the protein content in milk, while whey protein makes up the remaining 20%. Albumin is a minor protein that is present in milk in very small amounts, typically less than 1% of the total protein content.

Some dairy products, such as whey protein powder or whey protein isolate, may have higher concentrations of albumin because they are made by isolating and concentrating the whey protein fraction of milk. However, most dairy products, such as milk, yogurt, cheese, and butter, do not contain significant amounts of albumin.
