中文摘要: 法国墨红玫瑰是一种可食用玫瑰花品种，玫瑰中鞣质含量丰富。研究利用超临界CO2 萃取技术提取墨红玫瑰花中的鞣质，确定最优提取工艺为：墨红玫瑰花粉碎粒度40 目、萃取压力30 MPa、萃取温度60 ℃、萃取时间60 min、分离温度40 ℃、分离压力8 MPa、夹带剂乙醇浓度50%、流速15 mL/min、乙醇用量3 mL/g。最终得到超临界CO2 萃取墨红玫瑰花中鞣质的提取率为44.84 mg/g。
Abstract:Rose chinensis Jacq“Crimsin Glory”H.T.is a kind of edible rose，the tannins is rich in rose.The thesis analyzed the extraction rate of rose tannins by supercritical CO2 extraction method.It confirmed that the optimum extraction process：the grain size of rose powder was 40 mesh，extract pressure was 30 MPa，extract temperature was 60 ℃，extract time was 60 min，separation temperature was 40 ℃，separation pressure was 8 MPa，the density of entrainer-alcohol was 50 %，the ate of entrainer flow was 15 mL/min，the dosage of alcohol was 3 mL/g.Finally it got the extraction rate was 44.84 mg/g by supercritical CO2 extraction method.
