I have a bunch of egg white protein powder to take as a supplement. Only when I mix it in a shaker bottle, it foams up. Reading the answers about souffles I got the idea that if the egg yolk prevents foaming, and that yolks contain lecithin--that must be what the soy lecithin is for in the commercial egg proteins which don't foam up at all. But that didn't work. What is a powder--natural if possible--that I can add so that it mixes like the store bought stuff?

Have you tried a bit of fat? Like a drop of vegetable oil? –  Jolenealaska Dec 18 '13 at 15:35
    
@Jolenealaska I was hoping for something in powder form, so that I can prepare this all up front. Can fat come in a powder? –  Jeremy Dec 18 '13 at 15:57
    
Yes it can, but I can't think of a "straight fat" in a powdered form at the moment. Check this out though molecularrecipes.com/techniques/…, at least in the meantime. –  Jolenealaska Dec 18 '13 at 16:58
    
You may have less foamy results simply by mixing it by stirring rather than shaking. –  SAJ14SAJ Dec 18 '13 at 17:08

You're looking for a "food grade" antifoam agent. A brief look at the linked search results shows antifoam powders look to be mostly silicone based. They may or may not work for your heavy protein foam.

Reading up on the silicone based antifoam powders it seems like something I can't do at home, i.e.: how do I ensure 5PPM? Is this something that commercial products don't have to list? The stuff I'm comparing it with has this ingredient list: Egg Albumen, Cocoa, Artificial Flavor, Lecithin, Sucralose. –  Jeremy Dec 19 '13 at 17:43
    
@Jeremy are you using cocoa powder in yours? It may have enough fat to cut down the foam somewhat. –  sourd'oh Jan 17 at 22:08
    
@sourd'oh, I am and though it helps, it is still super foamy. I have to drink it, then put more water to pick up all the foam. I usually stop there because I get lazy, but it is still foamy the second time. I also tried putting some olive oil as someone mentioned above, but that didn't do much. –  Jeremy Jan 19 at 0:05
