The cold press technology is a process by which oil is extracted from nuts and seeds with minimal heating and friction. Thus, the inherent nutrients ensures a pure and rich oil.

The term cold pressed oils are derived from the German word kalt geschlagen which translates to cold plummeting. Cold Press technology has its roots in ancient civilizations all across the globe. From the Ming dynasty in China to Cholas in India and King Rama the second in Thailand. Using traditional stone grinders, the oil is extracted from flowers, fruits and seeds. This ancient technique has seen a revival in modern era with the accordance of the slow food movement wave which is spreading across the world. Slow food movement advocates use of traditional practice of food processing to not only preserve but also ensure a higher quality of processed food.

What is cold press technology?

  1. Filtering: The process begins with the filtering stage. In this stage, the seeds will be passed through a series of spaces which blasts air to remove impurities.
  2. Milling: The nuts and seeds are ground into a paste using heavy granite millstones or modern stainless steel presses, which are found in large commercial operations.
  3. Pressing: The semi-solid paste is slowly stirred. It is often done with a rotating screw which encourages the oil to separate from the solid parts and clump together. Once this happens, pressure is applied to force the oil out. It is one of the most important moments of the whole process, since this pressure may increase the temperature of the dough. If it exceeds a certain temperature, the oil may lose some of its properties.
  4. Filtering: The pressed oil goes through a series of filters that separate small pieces of the nut from the oil. The final part of this filtering process involves passing the oil through a cloth or paper to ensure that all impurities are removed from the oil.
  5. Decantation: Any remaining sediment is separated from the oil by the simple force of gravity. Thus, a 100% pure and natural oil that retains all its properties will be obtained.

Advantages of cold press technology

  1. Rich in antioxidants: The heat soluble antioxidants are retained as there is no external heat is used which might cause the antioxidants to dissolve.
  2. Rich in nutrients: Apart from anti-oxidants other nutrients like vitamins, minerals and other nutriactives are preserved due to minimal friction by the grinders.
