Embodiment 1

[0022] Litsea cubeba fruit was pre-soaked in NaCl solution with a mass concentration of 2% for 30 min, put into a still, and the inlet of the still was closed. Start to pass through atmospheric steam distillation, and keep opening the steam outlet valve leading to the condenser. The steam enters the oil-water separator after being condensed, and the litsea cubeba essential oil is obtained after being separated by the oil-water separator. After the oil and water in the oil-water separator are completely separated, separate the litsea cubeba essential oil, weigh the essential oil, and take the average weight of the litsea cubeba essential oil after 3 distillations. The duration of the whole distillation process is 180 min. Litsea cubeba essential oil yield is calculated according to formula (1):

[0023] Litsea Cubeba Essential Oil Yield = Litsea Cubeba Essential Oil Weight / Litsea Cubeba Fruit Weight×100 % Formula (1)

[0024] According to the calculation, the average yield of...

Embodiment 2

[0026] Litsea cubeba fruit was pre-soaked in NaCl solution with a mass concentration of 2% for 30 min, put into a still, and the inlet of the still was closed. Start to feed the steam. At this time, the steam is regulated, and the inlet pressure is controlled at 0.20 MPa. Distillation under this steam pressure is maintained for 8 minutes. After the end, the steam outlet valve leading to the condenser is quickly opened, and the steam is condensed. Enter the oil-water separator, and after the oil-water separation, the litsea cubeba essential oil is obtained. After the oil and water in the oil-water separator are completely separated, separate the litsea cubeba essential oil, weigh the essential oil, and take the average weight of the litsea cubeba essential oil after 3 distillations. The duration of the whole distillation process is about 30min. The yield of litsea cubeba essential oil was calculated according to the formula (1). After calculation, the average yield of litsea c...

Embodiment 3

[0028] Litsea cubeba fruit was pre-soaked in NaCl solution with a mass concentration of 2% for 30 min, put into a still, and the inlet of the still was closed. Start to feed the steam. At this time, the steam is regulated, and the inlet pressure is controlled at 0.25 MPa. Distillation under this steam pressure is maintained for 10 minutes. After the end, the steam outlet valve leading to the condenser is quickly opened, and the steam is condensed. Enter the oil-water separator, and after the oil-water separation, the litsea cubeba essential oil is obtained. After the oil and water in the oil-water separator are completely separated, separate the litsea cubeba essential oil, weigh the essential oil, and take the average weight of the litsea cubeba essential oil after 3 distillations. The duration of the whole distillation process is about 30min. The yield of litsea cubeba essential oil was calculated according to the formula (1). After calculation, the yield of litsea cubeba e...

Abstract

The invention discloses a method for rapidly extracting essential oil of cubeb litsea tree fruits through flash evaporation. The method comprises the extraction steps of washing cubeb litsea tree fruits, immersing the fruits in a saline solution with the mass concentration of 2-5% for 30-90 minutes, then charging the fruits into a distillation still, closing a feeding port of the distillation still, introducing pressurized steam for cooking and distillation under the steam pressure of 0.1-0.5 MPa, keeping the pressure under the pressure for 2-15 minutes, rapidly opening a valve of a condenserafter completion, feeding essential oil steam into an oil-water separator after condensation, and collecting essential oil to obtain the essential oil of cubeb litsea tree fruits. Compared with an existing cubeb litsea tree fruit essential oil steam distillation method, the time of the whole essential oil distillation process is shortened by 20-40 minutes, the steam use amount is decreased, the production energy consumption is reduced, the distilled essential oil yield is improved, and the production and extraction costs of the essential oil of cubeb litsea tree fruits are reduced.

Description

technical field [0001] The invention belongs to the field of extraction of litsea cubeba essential oil, and in particular relates to a method for extracting litsea cubeba essential oil by rapid flash evaporation. Background technique [0002] Litsea cubeba (Litsea cubeba), also known as Litsea cubeba, also known as Litsea cubeba, Litsea cubeba, or Litsea cubeba, is a small deciduous tree or shrub of the genus Litsea Cubeba in the family Lauraceae. Green to deep red or black. Litsea cubeba is widely distributed in various provinces (regions) in southern my country, and also in Southeast Asian countries. It has excellent characteristics such as fast growth, resistance to barrenness, strong germination, easy reproduction, and high yield. Litsea cubeba, one of the main spice economic tree species in China, is widely distributed and rich in resources in Jiangxi Province. Litsea cubeba essential oil extracted from the fruit and leaves of Litsea cubeba is widely used in food, medi...
