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!
In: Chemistry
It is to reduce the speed of oxidation of the powder and keep it “fresher” for longer. When packaged they replace the oxygen with a different inert gas, once opened that gas escapes and is replaced with atmospheric gases. In general, the lower the temperature the slower chemical reactions.
