Cold Press Sesame Oil 250 mL. The pressing technique is generally the oldest technique used to leak the liquid phase in a material consisting of solid and liquid phases and can also be defined as filtration under pressure. The basis of this technique is the leakage of the oil in the raw material out of the seed under pressure. When considered in terms of production technique - after the foreign substances in the oilseed raw material are cleaned, the squeezing process is carried out in presses without being exposed to high temperatures. Afterwards, a simple filtering process is performed and the oils are made ready for sale. Oils obtained by cold pressing technique - not exposed to high heat treatment during the process (40–50 °C) - not using solvents during the extraction of oil from raw materials and natural antioxidants - phosphatides - cerebrosides - carotenoids and phytosterols that are partially removed from the oil during the refining stages in conventional oil production. They stand out in terms of nutritional value because they contain higher amounts of some substances such as:
