The extractive technology and yield of the lutein, zeaxanthin and β-carotene from corn gluten meal extract were carried out by supercritical fluid extraction(SFE).
研究了超临界流体萃取(SFE)玉米蛋白粉中类胡萝卜素的提取工艺及其收率,结果显示:当45℃,26 MPa,改性剂体积分数为10%~20%,CO2流量为80~120 L/h,动态提取3 h时,类胡萝卜素的收率达到9%;用反相高效液相色谱法(RP-HPLC)测定了3种单体胡萝卜素(叶黄质、玉米黄质和β-胡萝卜素)的含量,其中叶黄质0。
【Result】Lutein content of pulp decreased rapidly at first and then slowly, however, the contents of the other four car.
【结果】果实进入着色期后,果肉叶黄质含量迅速下降,至果实成熟时下降平缓,而α-胡萝卜素、β-胡萝卜素、β-隐黄质和玉米黄素成分均呈上升趋势,尤其在采收前7～14d上升迅速。
α-carotene, β-carotene, lycopene, β-cryptoxanthin, zeaxanthin and lutein content in 53 varieties that belong to various citrus types were determined using HPLC.
