Sunflower Oil Expeller Pressed NonHydrogenated
AAA
If an Organic Merchant has an oil which has been extracted by hydraulic press but has been heated prior to pressing, he will refer to it as "pressed", not "cold pressed". The second method is by expeller, described in "The Low down on Edible Oils" as follows: "This uses a screw or continuous press with a constantly rotating worm shaft. Cooked material goes into one end and is put under continuous pressure until discharged at the other end with oil squeezed out." Temperatures between 200 and 250 degrees are normal. Obviously, this type of extraction does not qualify as "cold pressed" either. Organic Merchants will refer to it as "expeller pressed." Now with a hydraulicly pressed oil labeled "cold pressed" or "pressed", you can assume you have a crude or unrefined of. But this is not true of "expeller pressed" oil because the common fate of expeller pressed oil is to be refined after extraction. So you need additional information with the words "expeller pressed". Organic Merchants will use either the word "crude" or "unrefined" to identify this additional classification of acceptable oils. So Organic Merchants draws the line of acceptability at this point and, to review, you may expect us to carry only four classifications of oil: (1) virgin (2) cold pressed (3) pressed (4) expeller pressed-crude. And this paper is your tool to remind yourself of what we mean by those words. The last method is solvent extraction, described in "The Lowdown on Edible Oils" as "definitely dangerous to health." "Oil bearing materials are ground, steam cooked, then mixed with the solvent (of a petroleum base) which dissolves out of the oils, leaving a dry residue. The solvent is separated from the oils. This method is universally used by the big commercial oil processors because it gets more oils out quicker and cheaper. About 98% of the soy oil in the U.S. is solvent extracted.
