Protein Foam

I mix my whey protein powder (Optimum Nutrition) with juice of various liquids. It tends to create ridiculous amounts of foam. Drinking foam is just disgusting to me. I wondered if I had to drink the foam. Is it bad? Good? Does not differ much liquid? I know that milk and egg white foam, but why?

Rating: Awaiting unfoam drink is not an option. Try another brand is not an option. I just want to know whether or not the foam has a nutritional value and why it foams.

Moss is simply a stable (or relatively) air into a liquid emulsion that forms when a liquid is dispersed in the air it, and when the surface tension of the liquid is reduced to the energy involved in the reform of a uniform surface is greater than that required to remain in place around the dispersion of air bubbles. Some proteins have the effect of reducing the surface tension of water thereby to form foams. The foam is essentially the same as the bulk material, but with air dispersed in it. There are exceptions. For example, if you drink something that has dispersed, components such as .... little orange pulp, then they will be too big to stay in the foam, so that the foam consists essentially of water and protein, while the bulk liquid containing water, proteins and fruit solids. So you'd better drink it all - and not just the foam.
