COLD PRESSING

Cold pressing is the process of extracting oil from seeds, fruits, or grains without using high temperature or chemical solvents. It is a preferred method due to the preservation of the natural properties and nutrients of the oil. The raw material, i.e., seeds or fruits, is first ground into a paste, usually in a roller mill. Then this paste is subjected to the pressing process in a hydraulic or screw press, which generates pressure, squeezing the oil out of the raw mass.

During cold pressing, the temperature usually does not exceed 40°C, which is crucial for preserving nutrients such as vitamins, minerals, and essential fatty acids. As a result, cold-pressed oils are characterized by higher quality, deeper flavor and aroma, and better nutritional properties compared to refined oils.

However, it should be remembered that this process is more time-consuming and less efficient than refining methods, which may affect the higher price of the final product. Cold-pressed oils are best stored in a cool, dark place to avoid oxidation and spoilage. This method is particularly popular in the production of oils such as olive oil, flaxseed oil, hemp seed oil, and sesame oil, where preserving the taste and nutritional profile is a priority.
