About
Derived from dairy milk, casein protein powder is a dry supplement weighing about 4.2 ounces (118 grams) per cup.
Casein protein powder has a bulk density of roughly 4.2 ounces per US cup (0.5 grams per milliliter). A standard 2-pound (0.91-kilogram) container occupies about 7.7 US cups (1.8 liters) of volume. Because of the air trapped between its fine particles, it takes up far more space than denser kitchen staples like granulated sugar. Its volume-to-weight ratio is very close to white flour and slightly lighter than typical table salt.
From Wikipedia
Casein is a family of related phosphoproteins that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. Sheep and cow milk have a higher casein content than other types of milk with human milk having a particularly low casein content.
