EXPLANATION
OF COLD PRESSED EXTRACTION
Cold
pressed oil is oil which has been produced with the
use of a low heat technique. The introduction of
heat to the process of making oil will degrade the
flavor, nutritional value, and color of the oil.
Heat, however, increases the yield. For this
reason, cold pressed oil tends to be more
expensive, although it is also of higher
quality.
The
term "cold pressed oil" is subject to different
regulations, depending on the part of the world in
which it is made. In the European Union, for
example, oil which is labeled as cold pressed must
be produced in an environment which never exceeds a
certain temperature. The temperature varies,
depending on the oil, but is generally around 80
degrees Fahrenheit (27 degrees) Celsius.
When
oil is made, the nuts, seeds, or fruits being used
to make the oil are first ground into an even
paste. The paste goes through a malaxation process,
a slow stirring which encourages the oil in the
paste to clump. To extract the oil, pressure is
applied, forcing the oil out of the paste. Some
make cold pressed oil by using an oil stone alone
to remove the oil. After the oil has been produced,
it is graded and bottled.
Some
companies manufacture "expeller pressed oil" which
is made in a high pressure environment. The high
pressure is sometimes necessary with thick nuts and
seeds, but it creates heat through friction. Some
expeller pressed oil can be termed cold pressed,
because the temperature does not rise a great deal.
Other expeller pressed oil, however, is made at
very high temperatures, and cannot be considered
cold pressed oil. Companies may clarify by
specifically labeling a product "expeller cold
pressed oil."
Franch
OIL is extracted under controlled temperature of
below 80 degrees Fahrenheit (27 degrees Celsius).
This preserves the medicinal properties of the OIL.
A seed has "life" and when it is sowed in the
ground it would germinate and grow up to be a
beautiful plant. If you take the same seed and boil
it under high temperature and attempt to sow the
seed in the ground it would definitely not grow. A
dead seed is worthless!
