How fast will protein degrade?

[Toranye]

If I created a sort of butter made with whey protein,to make it a tasty addition or to make nice dietetic sandwiches. ButI am worried that the protein will become useless if it gets mixedwith something and will remain in the fridge for some time. Would itlast, or it must be taken fresh and just made?

I've never heard of this so... that said if it's kept refrigerated it should be ok.

people use protein powder with pancakes and home made bars etc with no problems. they also mix with coffee and use in blenders.. it is versatile
