Kylmäpuristettuun

Kylmäpuristettuun refers to a method of extraction where oils are produced without the use of heat. This process involves pressing the oilseeds or fruits mechanically, typically using a screw press or hydraulic press, at temperatures that are kept low, generally below 50 degrees Celsius. The absence of heat is crucial as it is believed to preserve the natural nutrients, flavor, and aroma of the oil. High temperatures used in conventional extraction methods can degrade some of these beneficial compounds.

This technique is commonly used for producing high-quality edible oils such as olive oil, flaxseed oil, and coconut oil, as well as for extracting essential oils from plants. The term "kylmäpuristettuun" directly translates from Finnish to "cold-pressed." Products labeled as such are often marketed for their purity and superior quality. The slower process and emphasis on maintaining low temperatures can sometimes lead to a higher cost of production compared to methods involving heat. The resulting oils are generally considered more nutritious and flavorful, making them a preferred choice for culinary and therapeutic applications.
