The extraction of products derived from vegetal species used in the food, pharmaceutical, and cosmetic industries are heavily dependent on the use of organic solvents such as hexane and dichloromethane. The use of these solvents at high temperature entails some limitation in the purity and quality of the extracted products and is not without consequence for human health and the environment. The alternative technology proposed would obtain high quality natural products using non - toxic solvents and is based on the capacity of supercritical fluids, and mainly CO2 to dissolve natural products in a very selective form based on precise combination of pressure and temperature. The development of this technology coupled with the careful choice of the raw materials used (organically grow plants) would result in the production of extracts with minimal alterations in the colours, scent and flavour and free form toxic residues to the benefit of consumers and the mentioned industries.
