I have been testing various different ways to extract vapable flavor concentrates from fruits, something that many people believe is not possible on a small scale.

The flavors I have managed to produce won't taste like vaping candy, but it will produce the flavor you extract from. it doesn't contain sugar or oil, doesn't gunk up the coils or wicks. The process I use is just a still.

To start, I use a sharp razor to slice THE THINNEST slices of the rind or skin of the desired fruit (lemon and orange are easy). try to make sure you are bisecting the cells of the rind, you will smell a very strong flavor of that fruit while doing this.

use the razor to 'chop' and 'dice' the sections of rind you have sliced off, as mechanical force is the first step in the breaking down of the cells in question . When the cell wall is broken, the inside of the cell which contains the pectins is exposed, accounting for the flavor you are experiencing.

Now, transfer the shavings into a glass jar and then fill the jar almost full with distilled water.

Now you will need a heat source, I use a crock pot as I believe boiling or even simmering water will produce more bitter flavors. Keep the crock pot on a lower setting, filled with water. once the water becomes the desired temperature, it's time to make a still out of this setup.

Use tin foil or whatever you are comfortable with to mold a funnel-like shape on top of the jar, forming as proper a seal as possible on the rim, and then mold that funnel piece around a straw or piece of adequate tubing. Bend the whole structure so that the straw leaves the jar at around a 45 degree downward angle for dripping.

Now place the jar with the shavings in the middle of the crock pot, with the straw hanging over the edge of the pot leading down to another container which will capture the distilled flavor. You may want to use foil to seal the top of the crock pot as a pseudo-lid as the water in the pot will evaporate rather quickly and will need to be replaced.

The process can take days, but after the time you will have a container filled with what is essentially fruity water, but the flavor will be relatively strong as the fruit matter had time to steep in the water as it distilled. This is the flavor concentrate. Feel free to strain as muc as you like, but since this process is relatively low-heat most of the sugars and oils will still be in the glass jar with the fruit pulp, and the drippings are safe to vape once added to a VG and H20 mixture.

Again, this will not taste like vaping fruit-flavored candy, and I am still tinkering to try to figure out how to retain high sour-notes in flavors like green apple.

any expansion on the subject is appreciated. Hopefully people get good results like I did.

I have made lemon, orange, tangerine, grapefruit and green apple flavors this way, all tasted like the fruit they came from but lacked a serious sour punch, probably due to the fact that it contains no fructose after the distilling.

Thoughts?

This is a very simplistic way of removing things we don't want to vape.

There may be something to be said, however, of replacing the distilled water in the jar with the fruit matter with ethanol. Usually catalysts are used to facilitate the production of esters but heat could work over time.
