Supercritical CO2 Extractors for Cold-Pressed Oils

The demand for high-quality cold-pressed oils has significantly increased in industries such as food, cosmetics, and pharmaceuticals. Supercritical CO2 extraction has become a preferred method due to its efficiency in preserving oil purity, extending shelf life, and ensuring solvent-free processing. The CO2 SUPERCRITICAL EXTRACTION MACHINE plays a critical role in extracting premium oils while maintaining their nutritional and therapeutic properties.

How Supercritical CO2 Extraction Works for Cold-Pressed Oils

Supercritical CO2 extraction utilizes carbon dioxide at high pressure and temperature, allowing it to function as both a liquid and a gas. This unique state enables CO2 to penetrate raw materials like seeds and nuts, efficiently extracting oils without degrading their quality.

Advantages of Using Supercritical CO2 for Oil Extraction

  • Preservation of Nutrients: The process occurs at lower temperatures compared to traditional solvent extraction, ensuring that essential nutrients, such as omega fatty acids and antioxidants, remain intact.

  • Solvent-Free and Chemical-Free Process: Unlike hexane-based extraction methods, supercritical CO2 does not introduce chemical residues, making the extracted oil safe for consumption and application.

  • Higher Yield and Efficiency: The ability to fine-tune pressure and temperature settings enables a more precise extraction process, yielding higher-quality oils with minimal waste.

  • Extended Shelf Life: Cold-pressed oils extracted using CO2 SUPERCRITICAL EXTRACTION MACHINE have lower oxidation levels, extending their usability without requiring artificial preservatives.

Popular Applications of Supercritical CO2 Extraction in Oil Production

  • Essential Oils: Extracting lavender, peppermint, and eucalyptus oil for aromatherapy and medicinal use.

  • Culinary Oils: Producing premium edible oils such as avocado, olive, and flaxseed oil.

  • Cosmetic Oils: Sourcing argan and jojoba oils for skincare and haircare formulations.
