The major difference between wood pressed oil and refined oil

1. What is the difference between wood pressed oil
and refined oil?

2. In the previous generation, people would
visit oil mills with an empty can for
purchasing the cooking oil from the oil
mills.
These oil mills have produced oils in a
natural way using a wooden press. This is
called as wood pressed oil.
It is also called as cold pressed oil. In Tamil,
it is popularly known as mara chekku ennai.

3. But in the last few decades, with the
arrival of refined oil, use of wood pressed
oil is reduced and it was only used very
rarely only in few traditional villages.
Wood pressed oils are making a
comeback now.
This because of the adverse health
caused due to usage of refined oil.

4. It is the main reason many Online Organic Store
Chennai has started selling wood pressed oils in their
stores.
How refined oil and wood pressed oil are prepared?
The modern method of oil extraction which used of
refined involves high supply of heat while in the
process of extraction.
The oil seed will be crushed and the crushed pulp
will be heated at a very high. Heat is added in order
to extract all the oil content in the seeds.

5. Apart from this, chemicals and solvents will be
added while extraction. With this method there will
be more oil yielded from the seed without any
wastage.
The traditional method of wood pressing or cold
pressing involves no external addition of heat.
The seeds will be crushed in the wooden axis. Most
of the heat generated while extraction will be
absorbed by the wooden axis.
Also, there is no external solvent added during the
process. Organic sesame oil, groundnut oil,
sunflower oil are prepared by this method.

6. What is the difference?
Since the heat is added during refined oil extraction, oil is
heated to very high temperature.
This will change the molecular nature of the oil in an adverse
way. It will remove the vital nutrients present in the oil.
Also, solvents added to the oil will bring toxic nature to the oil
we consume.
In the cold pressing method, oil which is extracted will be in its
natural molecular nature.
Though the yield will be less comparatively in wood pressed
oil, it is by far healthier than their modern day alternative.
