I've been experimenting with blending flavors into water based drinks, but these experiments have largely ended up with a thin oily layer on top of my watery liquid. What I require is an emulsifier to stabilize my oil-water mixture while:
1) Not adding any additional taste,
2) Not sequestering the taste of my flavor compounds,
3) Will preferably not turn my solution milky.
Some examples that do not work include adding sodium citrate (adds sour salt flavor), PG/DPG (bitter taste), ultrasound sonication (too expensive), and simply waiting for natural diffusion to occur (time-intensive).
Example flavors I am working with include beta-damascone (fruity, petal, apple flavor) and muscone (sweet, musk, vanilla-ish).
Some possibilities I can think of but have not tried include polysorbate, maltodextrin, and using a blender. Any helpful tips would be appreciated.
EDIT: I'd like to add that the flavors do mix if given enough time, albeit slowly, taking at least several days to weeks.
