As you can see, the process of refining food oils creates a unhealthy product prone to rancidity. Rancid oils in any form are particularly bad for your health because they introduce damaging free radicals into your body. - In Short It's cancer & heart attack causing for sure.
Dont fall for the False Ads : They say Fat Free Oils
HDL is good FAT - Protects your Heart - Prevent Heart Attacks (HDL in Cold Press Oils)
LDL is BAD FAT - Encourages the Heart Attacks (LDL in Refined Oils)
The Process of Extracting Seed Vegetable Oil in Factories (Refined Oil)
Heavy Heating - The seeds are heated (close to 300 Degrees - Jaw Dropping Heat) and steamed to start the oil extraction process. A mechanical press is used to apply high heat and friction to press the oil from the seed pulp. (Extreme Bad FAT -LDL is entered at this stage already.
HEXANE Chemical Process: The resulting seed pulp and oil are WASHED in a HEXANE 😱 solvent bath and steamed again to squeeze out more oil.
Note: That HEXANE (used above) is a chemical produced by the refining of crude petroleum oil. Chronic intoxication from HEXANE has been observed in recreational solvent abusers and in workers in the shoe manufacturing, furniture restoration and automobile construction industries where hexane is used as a glue. The initial symptoms are tingling and cramps in the arms and legs, followed by general muscular weakness. In severe cases, atrophy of the skeletal muscles is observed, along with a loss of coordination and problems of vision. In 2001, the U.S. Environmental Protection Agency issued regulations on the control of emissions of hexane gas due to its potential carcinogenic properties and environmental concerns.)
At this point, the seed/oil mixture is put through a centrifuge and phosphate is added to begin the separation of the oil and seed residues. After solvent and centrifuge extraction, the crude oil is separated and the solvent is evaporated and recovered.
Not Enough though - Refining Further to make it Flashy & Non Sticky.
The vegetable oil is then put through further refining techniques including degumming, neutralization and bleaching as explained below.
Water degumming: In this process, water is added to the oil. After a certain reaction period the hydrated phosphatides can be separated either by decantation (settling) or continuously by means of centrifuges. In this process step a large part of water soluble and even a small proportion of the non-water soluble phophatides are removed.
Neutralization: By treating the oil with caustic soda (sodium hydroxide) or soda ash (sodium carbonate). The refined oils are lighter in colour, less viscous, and more susceptible to oxidation.
Bleaching: The major purpose of bleaching is the removal of off-colored materials in the oil.
The heated oil is treated with various bleaching agents, Bleaching promotes oxidation since these natural antioxidants and nutrients are removed.
Deodorization: This is the final step in the refining of vegetable oils. Pressurize steam at extremely high temps (500 degrees or more - Oh mad..) is used to remove volatile compounds which would cause off odors and tastes in the final product.
Hydrogenated Shortening : A light solution of citric acid is often added during this step to refine it further.
