Technical Advantages of Cold Pressing for Functional Oils
Cold pressing is a mechanical extraction method used to retain the bioactive compounds in seeds. Our factory utilizes hydraulic pressing machinery to produce cold pressed flaxseed oil and cold pressed rapeseed oil. This process operates at temperatures below 60°C. Low heat prevents the degradation of Omega-3 fatty acids in pure organic flaxseed oil and preserves the natural Vitamin E in organic cold pressed almond oil. Solvent extraction methods often use hexane and high heat, which can strip nutrients and alter flavor. In contrast, our physical extraction method ensures the unrefined flaxseed oil remains pure and chemical-free.
We strictly control the moisture content of raw materials before pressing. This minimizes the risk of hydrolysis and oxidation. For cosmetic applications, such as flaxseed oil for skin, we use fine filtration systems to remove suspended solids without removing beneficial lipids. As a China oil manufacturer, we hold patents for our pressing technology. This equipment allows us to produce cold pressed canola and specialty oils that meet the clean-label requirements of European and North American markets. We offer flaxseed oil 500ml and bulk drums, ensuring the product retains its nutritional value during transport.
