The linseed/flaxseed oil extraction process means the linseed/flaxseed is extracted by organic solvents (such as gasoline, ethanol, etc.) to get oil. The extraction method uses solvent oil (No. 6 light gasoline) to soak the oil raw material linseed/flaxseed and extract the oil at high temperature. The oil first extracted is a mixture of organic solvents and oils, which cannot be eaten directly and can only be eaten after a series of oil refining processes (dewaxing, degumming, dehydration, deodorization, deacidification, decolorization and other chemical treatments). After extracted, the oil is generally lighter in color, which remains light original natural odor in the seeds or has no obvious odor. The extraction process can extract almost all the oil from linseed/flaxseed, and the economic benefit is very high. It is the most popular processing method in the modern oil industry.


All linseed/flaxseed oil starts with flax seeds that are harvested and cleaned. Seeds used to produce alkali refined oil are then optionally toasted or dried, then rolled. Putting the seed through rollers cracks the tough outer shell and turns the seed into a coarse meal. The meal is then heated and hydrated with steam to prepare it for pressing. Adding heat and moisture to the pressing process increases the yield of oil compared to just using pressure to crush the seeds. The drawback from heating and hydrating during pressing, is that the oil contains more plant matter and impurities that have to be removed through refining. After heat pressing, the remaining oil in the meal can be removed through solvent extraction using hexane. The solvent is then separated from the oil through distillation and reclaimed for future use.


Advantages: Very high oil yield, low cost and higher economic efficiency. The most popular processing method in the modern oil industry.
Disadvantages: Destroy parts of nutrients and there remain traces of organic solvents.
