I have a recipe which requires aromatizing olive oil by warming it up gently with some freshly peeled mandarin skins in it. This helps extracting the peel essential oils into the olive oil.
Usually I would use home grown, never treated mandarins for the deed, however now that I live in a country where mandarins are imported from abroad and treated with waxes and other products to boost their look, how can I extract the essential oils without taking along all the rest?
By buying mandarins that are untreated.
Organic fruit has to follow certain standards - look up what’s available in your locale and what the guidelines demand. There are “degrees of restrictions”, depending on the specific label, so do a bit of research. (With more information about your locale, we may or may not expand on that topic.)
Alternatively, sometimes you can find “straight from the farm” produce, but this can vary wildly and you may have to do your own research on how the fruit was grown.
The point is, all treatments are either water or fat soluble and with your extraction process you will always get both, so the safest bet is to make sure there is nothing in the first place.
