Q & A
What are the three methods of extracting essential oils from plant material discussed in the video?
-The three methods discussed are expression, extraction, and distillation.
How does the expression method work for extracting essential oils?
-The expression method involves physically squeezing plant material, like citrus peels, to release the essential oils. This method is commonly used on citrus fruits such as oranges and lemons.
What is the historical context of using expression for extracting essential oils?
-In the 19th century in Sicily, Italian people manually squeezed lemon peels onto a sponge until saturated, then squeezed the liquid out and filtered it to separate the essential oil from the water.
What are the three types of solvents used in the extraction method?
-The three types of solvents used are volatile solvents like alcohol, fats such as olive oil or lard, and hot air.
How did the French use fat for extracting essential oils in the 19th century?
-The French placed rose petals on top of oil, such as olive oil or lard, and heated the container in a water bath to a mild temperature to accelerate the extraction process. The oil would then be tested to ensure all the scent had been extracted, and the process could be repeated for months.
What is the amphorage process mentioned in the video?
-Amphorage is a process where oil, such as olive oil, is used to extract essential oils and then alcohol is used to extract the essential oil from the oil. The oil can then be reused for further extractions.
How does the distillation method differ from the extraction method?
-Distillation involves heating plant material with water or passing steam through it to release the essential oils, which are then collected through a condensation process. This method can be used with almost any plant material and is the only way to make hydrosols.
What are the two general ways of distillation mentioned in the video?
-The two general ways of distillation are water distillation, where the plant material is boiled with water, and steam distillation, where steam passes through the plant material without direct contact.
Why is steam distillation considered more efficient and safer than water distillation?
-Steam distillation is more efficient and safer because the plant material never touches the boiling water, reducing the risk of burning or overcooking the material, which can ruin the flavor of the essential oil.
What is a hydrosol and how is it made?
-A hydrosol, also known as floral water, is a byproduct of the distillation process, particularly steam distillation, where the steam carries the essential oils and water vapor, which is then condensed and collected.

πΏ Essential Oil Extraction Methods
This paragraph introduces three traditional methods of extracting essential oils from plant materials. The first method is expression, which is commonly used for citrus fruits like oranges and lemons. Historically, in Sicily during the 19th century, Italians would manually squeeze lemon peels onto a sponge to extract the oil. After saturation, the sponge would be squeezed to release the liquid, which would then be filtered and allowed to settle so that the oil could be separated from the water. The second method involves the use of solvents to extract the oil. Solvents can be volatile like alcohol or fats such as olive oil or lard. The French, also in the 19th century, used these to extract rose oil from petals by placing them on top of the oil and heating the container in a water bath. This process could take 12 to 40 hours per batch and was repeated over months. After extraction, alcohol could be used to separate the oil from the fat. The third method mentioned is distillation, which can be applied to almost any plant material and is the only method to produce hydrosols, such as rose water or lavender water. Distillation is done either by mixing the plant material with water and boiling it (water distillation) or by passing steam through the material (steam distillation). Steam distillation is considered more efficient and safer as it prevents the material from burning or overcooking, which could affect the quality of the essential oil.

hey this is the leo at lead time in
today's video
i'll show you the three ways to extract
essential oil
out of the plant material and explain
how people did in the history
and what are the benefits of its method
[Music]
the first method is called expression
it's commonly used on the citrus
material like a
orange peel or lemon peel when you
squeeze the
lemon peel you will see the drop flying
out of the skin
and within the drop a tiny bit of
essential oil
mixed with water in 19th century out of
sicily the italian people
use manually squeeze the lemon peel
onto a sponge and until the sponges are
saturated and squeeze the liquid out of
the sponge
one experience the worker can make of
one a quarter
pounds of a lemon squeeze after that
they filter the liquid
and let it settle until the oil
separated from the water
then collect the orange essential oil
the second way is the extraction
put the plant material mixed with a
liquid
that is called a solvent and as a
solvent will extract
essential oil out of the material there
are three different solvents can be used
the first one is a volatile solvent like
alcohol
and the second is the most common one
the use of fat in 19th century the
french people use
either olive oil or lard to extract
rose or essential oil from the rose
petals
what they did is that they put rose
on top of the oil they put the container
onto a water bath they heat up to the
mild temperature
and to accelerate the extraction process
but even though it still takes 12 to 40
hours for one batch until we
test the material and make sure all the
order has gone from the plant material
so that means this process is down
so this drain the oil and then put in a
container again
and refuel with another batch of a
material and they keep the process
for months until the oil has been
saturated
or the essential oil and after that
they either use the oil as is or the
use of alcohol to extract the essential
oil
out of the material if you use olive oil
you just pour alcohol into the olive oil
and then mix shake and then settle
to separate the alcohol out of the
olive oil because alcohol has a higher
solubility for the essential oil
so they extract them out of the olive
oil then they keep using the olive oil
for
the next process and this is called the
amphorage if they use a lot then
normally they
cut those a lot into a small pieces mix
with
alcohol and do the same thing as they
did with the
olive oil and then reuse a lot and the
third solvent is a hot air
they blow the material and then collect
the air
which has carried those essential oil
out of the material in terms of the
efficiency
and flourage has become very popular
because it uses two processed extraction
it can make essential oil very pure and
also keep the essential oil high quality
the third one is
distillation distillation is
the one of the most common method it can
be used to almost
any of the material to make essential
oil
and also this is the only way you can
make
hydrosol that's also called a flour
water
like a rose water or lavender water
distillation
has two general ways the one is a water
distillation
that means you mix the material with
water
and then boil them and collect the steam
and the second one is called a steam
distillation
so you put the material on top the water
so only steam will pass through the
material
and carry the essential oil out of the
plant material
and go through the condensation process
which is the same with the water
distillation comparatively
steam distillation is a more efficient
and more safe because when you mix a
material with water and then you're
boiling
you got to make sure you don't burn the
material
weasel water getting less and the
material can be stick on the container
somewhere either at the bottom or on the
side of the container
so that can cause the material to be
burned
overcooked this will ruin the flavor
of your dissolate the steam distillation
because the material they will never
touch
peeling portion so it becomes easy to
control
and also the temperature is more stable
so in today's video i introduce you the
three ways
to extract essential oil from the plant
herbs
hopefully you'll learn something today
