The container says it needs it after opening and I’ve never understood why a powder needs it. Is there something in the compounds of the powder that require that level of chill? I use it for baking cakes. Thanks!

So it seems to depend on the brand. Some brands say that and some don’t need to be refrigerated. Which makes it even more confusing to me.
Storing it in high humidity can cause the powder to cake, and high temperatures can affect the taste of the powder. So maybe this company is just trying to avoid that from happening and that’s why they are instructing you to store it in the fridge?
“A Utah State University study found that storage at 50 F/10 C preserved the flavor best.”

I’m sorry I’m honestly not sure but r/cooking and r/baking might be more of a help 🙂
