Great minds must think alike, because that was exactly what I was planning to do. Well okay, the fact that I can't really accurately measure anything primarily in any amount smaller than 1/4 tsp kind of forces my hand there =)
Maybe I am messing up the ppm calculations but here is my approximations with even 1/4 tsp in 10ml:
1 tsp = 4.2g of sugar or 5ml water. Dilute maltol or the crystals themselves vs. sugar can't differ that much in density. Using 1.25 ml that comes out to 1250ppm, or grams it is 1050ppm.
Most droppers are supposed to be close to 20 drops/ml but mine are 40ul or 25:1. So 2 of my drops per ml of
juice will be roughly 84-100ppm, and it should all work out. I think I only kind of made this thread because I forgot about the whole thing of making a base which then gets further diluted in the final product. Oops, well maybe someone else will find it helpful.
Somehow Linda seems to be able to dissolve TA into PG, see here. I actually made another mistake when I was looking at my guidebook and looked at the next entry, maltol propionate (strawberry-like):
Insoluble in water; soluble in fats and ethanol.
So that had left me guessing about PG. The real entry for maltol says:
Sparingly soluble in water; soluble in propylene glycol and ethanol.
