Embodiment 1
[0042] A method for extracting citronellal from Litsea cubeba head oil of the present invention, wherein, used Litsea cubeba head oil is obtained through crude extraction and distillation from the fresh fruit of Litsea cubeba, and the specific extraction method is as follows:
[0043] (1) Rough extraction of litsea cubeba:
[0044] The picked Litsea cubeba fresh fruit is cleaned, and 150 kg of fresh fruit is weighed and placed in a retort tank in water, and water (225 kg) that is 1.5 times the weight of the Litsea cubeba fresh fruit is added. Use 4kg of pressure water vapor as the heating carrier, and use a 1000L multi-functional extraction device for extraction, adjust the temperature and steam pressure of the water distillation, and control the return flow at 150L / h;
[0045] After the distillation, the material in the distillation flask is filtered through a filter screen, and the remaining water in the flask is used as the water for the next feeding. The dried fruit in th...

[0059] A method for extracting citronellal from Litsea cubeba head oil of the present invention, wherein, used Litsea cubeba head oil is obtained through crude extraction and distillation from the fresh fruit of Litsea cubeba, and the specific extraction method is as follows:
[0060] (1) Rough extraction of litsea cubeba:
[0061] The picked Litsea cubeba fresh fruit is cleaned, and 150 kg of fresh fruit is taken by weighing and placed in a retort tank in water, and water (225 kg) that is 1.5 times the weight of the Litsea cubeba fresh fruit is added. Use 4kg of pressure water vapor as the heating carrier, and use a 1000L multi-functional extraction device for extraction, adjust the temperature and steam pressure of the water distillation, and control the return flow at 150L / h;
[0062] After the distillation is over, the material in the distillation is filtered through a filter screen, and the remaining water in the flask is used as the water for the next feeding. The dried...

[0073] A method for extracting citronellal from Litsea cubeba head oil of the present invention, wherein, used Litsea cubeba head oil is obtained through crude extraction and distillation from the fresh fruit of Litsea cubeba, and the specific extraction method is as follows:
[0074] (1) Rough extraction of litsea cubeba:
[0075]The picked Litsea cubeba fresh fruit is cleaned, and 150 kg of fresh fruit is taken by weighing and placed in a retort tank in water, and water (225 kg) that is 1.5 times the weight of the Litsea cubeba fresh fruit is added. Use 4kg of pressure water vapor as the heating carrier, and use a 1000L multi-functional extraction device for extraction, adjust the temperature and steam pressure of the water distillation, and control the return flow at 150L / h;
[0076] After the distillation is over, the material in the distillation is filtered through a filter screen, and the remaining water in the flask is used as the water for the next feeding. The dried ...
