Extraction Methods
Steam Distillation
Solvent Extraction
Steam distillation is the most common method used
to extract peppermint essential oil. This process
involves passing steam through a vessel
containing crushed peppermint leaves. The steam
carries the volatile oil molecules, which are
then condensed and collected.
Solvent extraction involves using a solvent to
dissolve the essential oil from the plant
material. This method is not typically used for
peppermint oil extraction due to concerns about
the potential presence of solvent residues in the
final product.
Cold Pressing
Cold pressing, also known as expression, is a
method used to extract essential oils from citrus
fruits. It involves pressing the fruit's rind to
release the oil. This method is not commonly used
for peppermint oil extraction.
