The purpose of Superfood is to provide nutrition. Tincturing Superfood would not enhance its value and very probably decrease its value because you are losing valuable fiber and other nutrients in the tincturing process. Cervasie Yeast for example cannot effectivly be tinctured and would lose its B12 and other vitamins. In my opinion tincturing Superfood would be pointless.

i think the key is if the separate ingredient is water soluble
if you take a powder and it total dissolve in water it shouldn't not be tincture.

orange peel is something better as a tinture or a juice ???
