Study on Extraction of Concretes from Osmanthus fragrans and Jasminum sambac by Supercritical Carbon Dioxide |
| |
| Abstract: | Osmanthus fragrans and Jasminum sambac were extracted with supercritical CO_2 at different conditions of pressure,temperature and contact time to estimate the yield and quality.The yield of Osmanthus concrete was 0.251% at better conditions of pressure range 12～16MPa,temperature range 308～318K and contact time 1.5～2h,and the yield of Jasminum concrete was 0.240% at better technological parameters of pressure range 12～15MPa,temperature range 308～323K and contact time 1～1.5h.The CO_2 extracts had higher yield and better quality compared with conventional extracts. |
