síbiotech - Lyophilisation Process Technology for Biologically Active Compounds

SHARE
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.

Lyophilisation, or freeze-drying, is a dehydration process at low temperatures under vacuum conditions.

In the lyophilization process, the raw material is rapidly frozen, followed by a pressure reduction in the lyophilization chamber to a vacuum below 1 mbar, initiating the sublimation process. During this process, the water in the product transitions directly from a solid (frozen) to a gaseous state through sublimation. The ice present in the frozen product is transformed into a gaseous state and directed to a condenser, effectively removing moisture in vapor form from the raw material.

Advantages of the Technology

The key advantage of lyophilisation technology lies in preserving up to 98% of the biologically active compounds present in the material being dried. síbiotech employs lyophilisation to dry microalgae, fungi, berries, fruits, medicinal plants, and their processed products. This approach allows for retaining the material’s favourable properties and biological functionality, distinguishing it from conventional drying technologies.

síbiotech primarily utilises lyophilisation technology to prepare raw materials for supercritical fluid extraction to obtain biologically active compounds.

For extraction to be effective and standardised, high-quality raw materials with a high concentration of biologically active compounds and minimal moisture content are essential.
