Cold Pressed oil
How are oils made?
COLD PRESSED OIL
Naturally, oil seeds can be pressed to extract oil (Like pressing juice from a fruit).
HAPRAPPA COLD PRESSED oil processing steps
Oil seeds are cleaned and dried to remove any
Natural drying using sunlight
The seeds are then crushed using a slow grinding machine with a Pestle and Mortar. (Just like pressing juice from a fruit)
The oil extracted is then filtered to separate the oil from the
Natural gravity sedimentation
“Chekku”, “Ghani” & “Kolhu” oil are some colloquial words used in India to describe Cold Pressed Oil machines.
In ancient times, a cow was used to grind oil seeds to make oil. These days we use a mechanical oil pressing machine as shown in the image.
Other oils seeds such as rapeseed (canola), soybean, corn, sunflower, safflower, etc
Refined oil processing steps
Oil seeds (groundnuts, sesame, coconut, sunflower seeds,
The mixture of oil and seed pulp is then chemically processed with a hexane solvent to extract any residual oil from the pulp. (Hexane is produced by refining crude
This resulting mixture is then put through a centrifuge and phosphate is used to separate the oil from the seed residues
Water degumming: Here water is added. This reaction with water results in hydrated
Neutralization: The resulting product from the above steps contains fatty acids, phospholipids, pigments, waxes, etc. These impurities are removed by using caustic soda (sodium hydroxide) or soda ash (sodium carbonate). The refined oil is lighter in color, less viscous and easily prone to oxidation
CAUSTIC SODA/SODA ASH
Bleaching: This is done to remove off coloured materials. Bleaching agents are used in this
Deodorization: Pressurized steam at very high temperatures (500F) is used to remove volatile compounds which cause off odours and taste in the final product.
This process kills all the nutrition and alters the
When you take a natural food product and expose it to multiple chemical processes, how can it be natural and healthy?
Multiple studies have linked consumption of refined oils to many chronic diseases. Chemically extracted oils lead to inflammation within the body, elevated blood triglycerides and an impaired insulin response, etc.
These days Refined oils are advertised as “Vitamin +”. Oil should be a natural product!
Making oil is such a simple process. Then why do Refined oils exist?
Seeds such as rapeseed (canola), soybean,
corn, sunflower, safflower, etc CANNOT yield oil through natural extraction techniques. To extract oil from these seeds, only chemical refining process works. Since 1950s, manufacturers also started using refining process for groundnut, sesame, coconut, etc.
Refined oil extraction has higher oil yield. For example, in cold pressed method we need 2.5kg of groundnuts to make 1 litre of groundnut oil. The refined process will extract 1 litre of oil from 2.2 kg of groundnuts
Since refined oil is neutralized for taste, colour and odour, very low quality oil seeds are used. (Cold pressed oil has to use only good quality oil seeds; otherwise, a consumer will indentify the lapse in quality)
This is the most shocking part. Palm oil constitutes nearly 45% of edible oil consumed in India. Palm oil is the most consumed oil. How? Nobody goes to the grocery store to buy Palm oil and there isn’t Palm oil in grocery store shelves, yet we consume so much palm oil. Cheap and neutral oils such as palm oil, cotton seed oil, etc. are mixed with other oils for profits. This is a widespread and
accepted “Oil blending” practice in the oil industry.
Refined oil has longer shelf life as it is chemically treated. There is nothing to be spoilt in it as there is no organic life in it
Palm oil is the most consumed oil in India. This is because refined oils are blended with Palm oil.
