	I don't think so because the solutions of pure casein that I have 
are colored vaguely yellow.  It's not the lactose because 20% lactose is
clear.

I think your first guess about the lipids is right.  Skim milk still
has a little fat in it.  (When does Fat-Free not mean fat free?  When
the FDA says it can.)

Anyone else?
