I would like to add a vitamin powder to some food I have but unfortunately the vitamin powder(I have read) degrades when I attempt to put in water for more then a couple days it looses its benefits according to this question. What options do I have to add the powder to some food I have such that it doesn't involve heat/water? I can't simple sprinkle it on top because well it the food I am trying to add it to is round and isn't an ideal solution. Think trying to add it to check mix. I am trying to prepare the food in advance if that isn't clear.
Treat yourself as if you were a young child, and pretend you're getting a 3-year-old version of yourself to take some medicine in powdered form :)
I personally like just putting it on a cold sorbet; we did this when our youngest could not stand the taste of an antibiotic, so we had to crush it in pill form and find ways to have her ingest it. Raspberry sorbet with sugar (and amoxicillin) on top did it.
You could also look at stabilizing it in some milk chocolate that melts at a relatively low temperature, but I don't know how you'd test the efficacy of the method, because I don't know how to measure vitamin strength after trying something like that.
But desserts are generally the best vessels in which one can sneak medications agreeably past even sensitive palates, so I'd go that route.
You could also try fruit - e.g. watermelon, just consume it immediately.
