I purchased protein shake powder a few months ago. I've been storing it at room temperature in my kitchen, temporarily also in the fridge. Produced in 08/2010, expriation date 02/2012.
What kind of preservatives does this powder contain, and are they any way problematic?
Come on, there must be powerful preservatives inside this stuff, because it has high nutritional value, has very low grain size, is very sweet and, thus, should be a really good breeding ground for microorganisms. But until now, nothing seems to have changed inside the plastic containers. The coconut taste sometime is a bit murky, but this can be by design or maybe the concentration was too high.
This question: Protein mix - How long can it sit? refers to the max duration a shake can be stored after water has been added and the shake is ready to drink (2 hours). I'm referring to the powder form here.
