Oil extracted through a mechanical process without heat, typically using a hydraulic press, is often chosen for specific applications. This method preserves delicate flavors, aromas, and nutrients that might be lost at higher temperatures. A common example is found in the food industry, particularly with extra virgin olive oil.
Unrefined oil offers several advantages. Its lower processing temperature avoids the introduction of potentially harmful compounds created by heat. This preservation of natural characteristics results in a higher quality product, often preferred for culinary uses and certain cosmetic applications. Historically, this mechanical extraction method predates modern refining techniques and represents a traditional approach to oil production.
