Meyenburg claims that the orange/pink sediment on the bottom of the carton
is "milk solids".
"What is the thick, creamy substance at the bottom of my carton?
Don't be alarmed! It does not mean that the milk is curdled. The sediment
you are seeing is the result of a settling of milk solids. This separation
may be a cloudy white, tan or pink in color. This is a normal occurrence in
goat milk and tends to occur more frequently in the spring. In the interest
of keeping our products as pure as possible, we do not use additives that
would prevent this settling from occurring. Vigorous shaking or stirring
should mix the sediment back in."
