Külmpressimise

Külmpressimine is an Estonian term referring to a method of extraction or processing that involves applying pressure at low temperatures. This technique is most commonly associated with the production of oils from seeds and nuts. Unlike methods that use heat, külmpressimine aims to preserve the natural nutrients, enzymes, and flavor profiles of the source material. The process typically involves mechanical pressing of the seeds or nuts without any added heat or chemical solvents.

The temperature during cold pressing is kept below a certain threshold, often around 40-50 degrees Celsius, to prevent degradation of beneficial compounds like omega-3 and omega-6 fatty acids, vitamins, and antioxidants. This gentle extraction method results in oils that are often considered to be of higher quality and possess a richer, more authentic taste compared to oils produced through heat or solvent extraction.

Külmpressimine is widely used for producing various edible oils, including flaxseed oil, sunflower oil, pumpkin seed oil, and olive oil. Beyond food applications, the principle of cold pressing is also applied in other areas, such as in the extraction of certain plant-based cosmetic ingredients. The resulting oils are valued for their purity and the retention of their natural properties, making them popular in health-conscious markets and for culinary uses where flavor and nutritional integrity are paramount.
