• What is the difference between expeller pressed and cold pressed oil extraction?
  • The difference between expeller pressed vs cold pressed oil extraction is that during the latter process, the fruit/nuts/seeds are pressed using either a bladder press (used with softer fruits), hydraulic press, or low resistance expeller pressing so as not to exceed the 122¡ãF temperature requirement.
  • How does an expeller press work?
  • An expeller press or ¡°screw press,¡± is a machine that presses seeds and nuts through a cavity and uses intense friction and pressure to extract oil. During this process, there isn¡¯t any added heat but since the seeds are pressed using friction, heat is created (around 140-210? F). Once the seeds are pressed, the oil is removed.
  • Are all cold pressed oils expeller pressed?
  • All oils that are labeled cold pressed fall under the category of expeller pressed oils. However, it is important to note that the converse is not always true¨Cexpeller pressed oils do not universally qualify as cold pressed oils. As a consequence, cold pressed oils can be categorized as a specialized subset of expeller pressed oils.
  • Why is expeller pressing better than cold pressing?
  • Expeller pressing extracts a comparatively higher amount of oil in comparison with cold pressing. This is because the process uses higher screw rotation speeds, also generating more friction and heat. This significantly increases oil yield, making expeller pressing more efficient and economical in comparison with cold pressing.
  • How does a nut oil expeller work?
  • An expeller is a big screw that is tightened until it crushes the nut/seed and causes the oil to run. This method provides yields of only 65-70% of the oil. Many companies then try to extract the rest of the oil using the chemical solvent. Mechanical pressing may create high temperatures, especially when squeezing hard nuts.
  • Are oil bottles cold pressed or expeller pressed?
  • Unless an oil bottle is labeled ¡®cold pressed¡¯ or ¡®expeller pressed¡¯, terms such as ¡®hexane free¡¯ do not ascertain that it is mechanically pressed. Hence, when looking to purchase pressed oils, ensure that the labels explicitly indicate that it is cold or expeller pressed.
