三种香菜根挥发性成分提取工艺的研究

Study on Extraction Technology of Volatile Components from Three Kinds of Caraway Roots

本文研究了三种香菜根挥发性成分提取工艺.结果表明:水蒸气蒸馏法的最佳工艺提取条件为1:10、蒸馏时间为2.5 h,在此工艺条件下,提取率为1.2%;索氏提取的方法最佳工艺条件为料液比为1:15,提取时间为6 h,在此工艺条件下提取率为1.5%;超声萃取法最佳提取条件为料液比1:10、提取时间80 min、提取功率60 W,在此条件下,提取率为2.3%;与水蒸气蒸馏法、索氏提取法相比,提取率分别提高了1.1百分点和0.8百分点.

The extraction technology of volatile components from three kinds of coriander roots was studied in this paper. The results showed that the optimum extraction conditions of steam distillation were material ratio of 1 ∶ 10 and distillation time of 2.5 h. Under these conditions, the extraction rate of volatile components from coriander root was 1.2%. The optimum extraction conditions of Soxhlet’s method were material-liquid ratio of 1 ∶ 15 and extraction time of 6 h. The extraction rate of coriander root was 1.5%. The extraction rate of coriander root was studied by ultrasonic method. The optimum extraction conditions were as follows: the ratio of material to liquid was 1∶ 10, the extraction time was 80 minutes, and the extraction power was 60 W. Under these conditions, the extraction rate was 2.3%. Compared with steam distillation and Soxhlet extraction, the extraction rate increased by 1.1 percentage points and 0.8 percentage points respectively.
