基于水蒸气蒸馏法提取橙子皮柠檬烯的影响因素研究

Influence Factor of Extracting Limonene from Orange Peel Based on Water Steam Distillation

采用水蒸气蒸馏的方法提取橙子皮中的柠檬烯,研究加水量、物料粒度、添加助剂等因素对柠檬烯提取产率的影响。结果表明:将橙皮粉碎后加入4mL/g、添加助剂氯化钠的柠檬烯产率最好;采用旋转蒸发可以克服水蒸气蒸馏提取试验过程装置变换繁琐、加热不易控制、不能连续添加自来水等繁琐步骤。

Water steam distillation, corquer particle size, additive addecl were studied. The results showed that amount 4 mL/g,add additive of sodium chloride limonene yield was the best. Co-evapordting method could trivival experiment transform trival, diffcult to control heating, can not add water consnuusly compared with steam distillation.
