Supercritical CO2 Extraction and Fractionation of Essential Oils from Canadian Hops and Mint

This project aims to evaluate environmentally friendly supercritical carbon dioxide (SC-CO2) extraction and fractionation processes to obtain essential oils from Canadian hops and mint to better serve the industry and consumers. Using current extraction methods, the yield and purity of the extracts obtained are compromised, as well as its volatility for further use in food, and cosmetic applications, requiring further research on the stability for practical use of these extracts and fractions in various industries. In addition, more research is needed on scale up of this technology. The use of SC-CO2 as the solvent allows easy separation of the solvent from the extract and fractions. Results obtained from SC-CO2 extraction in terms of yield and product quality will be compared to commercial essential oils. A high yield of essential oils and their stability will allow further use and commercialization as ingredients to various industries in Canada and international markets, strengthening Canada’s agricultural and processing sectors.
