Advances in hop extraction with supercritical carbon dioxide
Sustainable solution | In the past, hops have been extracted with supercritical carbon dioxide up to a maximum pressure of 300 bar. This year, an extraction plant will be commissioned that will operate at 500 bar of pressure. The primary motivation behind increasing the pressure to 500 bar is the energy savings gained due to the enhanced properties of CO2 as a solvent at this pressure along with the greater contribution to sustainability. The hop extracts obtained at 500 bar are only slightly different than those extracted at 300 bar of pressure, which is the focus of this report.
