Cold Pressed Oils

Sesame Oil for cooking

The oils you use for everyday cooking are extracted from seeds, fruits, vegetables, and nuts. From olive oil to sesame oil, the way that oil is extracted has a direct effect on how the oil tastes in your food and the number of nutrients it has to offer. Using heat to extract the oil produces more of it, but heat can degrade the oil’s flavor and nutritional quality. Using low-heat methods produced higher quality oil, albeit in lesser quantities. Extracting oil through cold-pressing involves crushing the seed or nut and forcing out the oil. Presses come in a range of sizes, from small sizes for home use to huge commercial presses. The seeds are dropped inside a cylinder that contains a rotating screw. This screw grinds and crushes the seeds until the oil is extracted. Small holes in the bottom of the cylinder allow the oil to escape into a collection container. Although some heat is generated through friction as the screw breaks down the seeds, it’s usually not enough heat to damage the oil.
