síbiotech - Lyophilisation Process Technology for Biologically Active Compounds

Lyophilisation, or freeze-drying, is a technique involving dehydration at low temperatures under vacuum conditions, crucial for preserving biologically active compounds. The process begins with rapidly freezing the raw material, followed by reducing the pressure to create a vacuum under 1 mbar, which initiates sublimation. This method allows the ice in the product to transition directly from a solid to a gaseous state, effectively removing moisture as it turns to vapor and is captured by a condenser. Unlike conventional drying methods, lyophilisation preserves up to 98% of bioactive compounds. síbiotech leverages this process to dry materials such as microalgae, fungi, berries, fruits, and medicinal plants, maintaining their biofunctional properties. This dried material is then primed for supercritical fluid extraction, ensuring high-quality end products with a rich concentration of active compounds and low moisture, essential for effective standardised extraction.

síbiotech HIPPOCOR - Supercritical Fluid Extraction Technology

síbiotech provides a cutting-edge technology for the extraction of natural, biologically active compounds through supercritical fluid extraction with CO2. This method effectively isolates valuable constituents such as Omega-3, Omega-6, Omega-9, and beta-sitosterol from sources like sea buckthorn seeds. The process involves using CO2 under conditions surpassing its critical pressure and temperature limits, allowing it to function as an effective solvent, extracting both fat-soluble oils and waxes without chemical modification. This environmentally friendly approach offers notable advantages by precluding the use of organic solvents, ensuring extracts free from harmful residues, and maintaining microbiological stability. The technology further enhances the integrity of the extract by preventing oxygen exposure, preserving its biologically active nature.
