RegulationsThe term "cold pressed oil" is subject to different regulations, depending on the part of the world in which it is made. In the European Union, for example, oil with this label must be produced in an environment that never exceeds a certain temperature. This varies depending on the source material, but is generally around 80° to 120°F (27° to 49°C). In the United States, labeling is not as regulated, so consumers generally need to contact companies directly to enquire as to their manufacturing process. Though many companies make a similar product, expeller pressed oil, it usually can't be designated as cold pressed, since the expelling process involves high levels of pressure, which creates more heat.
