Supercritical CO2 extraction is gaining popularity as a green and efficient method for extracting essential oils and other valuable compounds for the cosmetic and fragrance industries. A critical aspect of this technology is the recovery process, and chilled recovery plays a vital role in preserving the quality of the extracted aromas and compounds.

Here’s why chilled recovery is so important:

• Preservation of Delicate Aromas: Chilled recovery helps to maintain the integrity of volatile aroma compounds that might be lost or degraded at higher temperatures. The lower temperature prevents thermal degradation, resulting in a more complete and true-to-source aroma profile.
• Better Recovery of Extracts: By chilling the recovery phase, the precipitation of the extracted compounds is enhanced, leading to a more efficient collection of the desired product.
• Multi-Mode Separation: Some systems, like the extraktLAB M2.5, allow for multi-mode separations with different solvents, with or without CO2, and hot water subcritical water extractions at high pressure.
• CO2 Recycling: CO2 recycling is important for reduced CO2 usage. Some systems enable you to reduce CO2 by recycling.
• GMP Compliance: GMP compliance is important and has to do with the selection of materials that won’t contaminate the sample and also the traceability of the materials so that the materials themselves are not contaminating the extract.
