| Abstract: | The hop concrete was produced with dried hop pellet by the supercritical CO2fluid extraction which decreased the α-acid loss and increased the use rate of hop. The suitable technological parameters were 1 mm in diameter of the smashed hop pellet, extraction pressure,20～25 Mpa extraction temperation 40～45℃extraction time 3～4 hr, separation pressure 35～55 ℃, separation temperature 35 ～55℃, and the rate of CO2 flow 40～45 L/h.. |
