Then the oil and defatted flakes are each steamed to evaporate the hexane. Hexane may be present in the following foods under the conditions specified: (a) In spice oleoresins as a residue from the extraction of spice, at a level not to exceed 25 parts per million.

“Many soy foods, thought of as ‘healthy options’ on grocery store shelves, contain ingredients that were processed with a neurotoxic and highly-polluting … Delve deeper into the nuances of organic with these videos. It has low viscosity and a low heat of vaporization. Keep in mind that labels that state the product is made with organic ingredients may still use ingredients that have been exposed to hexane. No study has ever tested how much hexane a person can safely eat over the course of a lifetime, but rodent studies suggest that your Thanksgiving tofurkey isn’t going to kill you.

This is most common in factories where oil extractions, industrial cleaning, or certain manufacturing operations take place. Most consumers already know that organic soybeans were not grown with toxic pesticides and other agrichemicals and are never grown with genetically engineered seed.

Most hexane exposure comes through the air, however, if you wish to eliminate hexane residues from your diet, you can choose foods that are "100-percent organic" and oils that are expeller-pressed rather than solvent-extracted. Hexane is toxic, and exposure to large amounts of it can cause neurological damage. The solvent of choice is commercial hexane, a petroleum fraction with a boiling range of 65–70 °C.

In the food industry, hexane is used to extract the vegetable oil from plant seeds such as canola, soybeans, sunflowers, and corn because it is more efficient and less expensive than squeezing out the oil with presses.
