摘要
为了充分开发丰富的甜橙皮资源,增加其经济附加值,在单因素试验基础上采用正交试验对甜橙皮中橙皮苷的提取工艺条件进行优化,得出最优提取条件:在70℃条件下,用30倍于甜橙皮粉的80%甲醇,恒温提取3.5h。比较了6种甜橙皮中橙皮苷含量,相差不大,且含量相对较高。同时根据所得优化参数,考察了索氏提取、微波消解/萃取及快速萃取3种设备,结果表明:快速萃取效率较高,可作为工业化生产的首选设备。所得提取工艺稳定,选用的设备操作简便、快速,满足工业化需求,具有良好的应用前景。
In order to develop the resource of sweet orange peels with maximum economic profits, optimal extraction conditions of hesperidin from sweet orange peels were explored by single factor and orthogonal experiments. Results indicated that the optimal extraction conditions were extraction temperature of 70 ℃, extraction time of 3.5 h and material-liquid ratio of 1：30 with 80% methanol as solvent. Through comparing the contents of hesperidin in 6 kinds of samples, no obvious difference was observed. Extraction efficiencies of different extraction equipments were compared. Rapid extraction-ASE exhibited the highest extraction efficiency and can be used for industrial production. This extraction method has promising potential due to its stability, simple equipment, less time consumption and industrial scale.
