What Does Biological Value Mean?
Biological Value (BV) measures protein quality. It is measured by nitrogen retention compared to the amount of nitrogen taken in. Amino acids have nitrogen incorporated into them, which is where that measurement comes from.
By comparing how much goes in to how much stays in, you get the Biological Value of the protein.
