Supercritical CO2 extraction. From new developments to Toll Manufacturing


Abstract/Technology Overview

CO2 under certain conditions of pressure and temperature higher or near its critical point acquires intermediate properties between liquid and gas and that makes it a fluid with a powerful solvent capacity, that can be used in many industrial applications some of them linked to extraction as an alternative to traditional organic solvents, and some specific ones linked to purification, impregnation, drying, or encapsulation processes.

 

The industrial applications of supercritical and subcritical CO2 technology are multiple. This technology has application for some of the most important mass consumption industries such as food, cosmetics and pharmacy. We talk especially about:

 

    Extraction processes.

    Deodorization and decontamination processes.

    Impregnation processes.

    Generation of microencapsulated.


Technology Features, Specifications and Advantages

Some advantages of the use of supercritical CO2 are linked to the following properties of this fluid:

  • Green solvent, inert, non toxic, approved for BIO/ORGANIC products, and for GMP processing (pharma & cosmetic)
  • Clean and Safe: non flammable, able to work under pressure
  • High selectivity because solvent power depends on pressure and temperature conditions and can be fitted
  • It becomes gas and volatilizes after depressurization: no solvent removal stages are required
  • Processes are performed at low temperatures and without oxygen contact: able for thermolabile substances or to avoid oxidation of molecules
  • Great capacity to extract substances and without generating waste or damaging the starting material: can be used to defat, dry, remove non desired aromas, remove pesticides,…
