machine abrasion extraction
binomial name: machine abrasion extraction
as a method of “expression,” this process of extraction completely sidesteps the use of heat and instead relies upon centrifugal force to separate the essential oil from its botanical source. in the past, oil from citrus rinds was collected by hand, but today’s method involves more modern machinery. using a process called machine abrasion, the outer peel of a citrus fruit is peeled off and removed by pressurized water. this mixture is then rapidly spun into a centrifugal separator which isolates the precious oil from the rest of the mixture.
benefit: machine abrasion extraction is a quick and modern way to extract essential oils from the rinds of citrus fruits.
