Does Rice Protein Powder go bad after a certain amount of time after opening?

Or does it stay good, even if opened, until it's expiration date? I was wondering because I have a big thing of it and it's been opened for a few months. (not expired till next year though) Wouldn't it grow bacteria or something? Thanks. :)


It's BROWN rice protein powder so it has a good amount of protein. Also, I CAN'T eat peanuts. I use it in the mornings for a breakfast shake because I hate eating in the I drink.

    With all the talk about china putting melanine in grain to fake increased protein levels, I would pitch it myself.

    You will be able to use it until it is all eaten up.

    Rice protein you say. Rice is very poor in proteine.

    A hand full of peanuts is probably better than a shovel of rice.
