Embodiment 1

[0026] A method for improving the extraction rate of chamomile essential oil, comprising the following steps:

[0027] (1) Dry the harvested Roman chamomile flowers to make the content 8%, and the essential oil content in the chamomile flowers is 0.73%;

[0028] (2) Mechanical activation: Take 50kg of sun-dried chamomile flowers and add them to a vertical stirring ball mill, and mechanically activate them for 5 minutes at a speed of 100r / min to obtain chamomile powder;

[0029] (3) Soaking: Add the above-mentioned chamomile powder into a retort, then add 0.4kg of cellulase and water, pressurize with a stone plate so that the water just soaks the chamomile powder, soak at room temperature for 2 hours, and obtain the extract;

[0030] (4) Distillation: Water vapor is introduced from the bottom of the distillation tank to heat the extract, and the extract is boiled and then extracted for 60 minutes to obtain mixed steam;

[0031] (5) Condensation: the mixed steam obtained above ...

Embodiment 2

[0036] A method for improving the extraction rate of chamomile essential oil, comprising the following steps:

[0037] (1) Dry the harvested Roman chamomile flowers to make the content 8%, and the essential oil content in the chamomile flowers is 0.73%;

[0038] (2) Mechanical activation: Take 50kg of sun-dried chamomile flowers and add them to a vertical stirring ball mill, and mechanically activate them for 5 minutes at a speed of 150r / min to obtain chamomile powder;

[0039] (3) Soaking: Add the above-mentioned chamomile powder into the retort, then add 0.5kg of cellulase and water, pressurize with a stone plate so that the water just soaks the chamomile powder, soak at room temperature for 3 hours, and obtain the extract;

[0040] (4) Distillation: Water vapor is introduced from the bottom of the distillation tank to heat the extract, and the extract is boiled and then extracted for 60 minutes to obtain mixed steam;

[0041] (5) Condensation: the mixed steam obtained abov...

Embodiment 3

[0046] A method for improving the extraction rate of chamomile essential oil, comprising the following steps:

[0047] (1) Dry the harvested Roman chamomile flowers to make the content 10%, and the essential oil content in the chamomile flowers is 0.68%;

[0048] (2) Mechanical activation: Take 50kg of sun-dried chamomile flowers and put them into a vertical stirring ball mill, and mechanically activate them for 3 minutes at a speed of 200r / min to obtain chamomile powder;

[0049] (3) Soaking: Add the above-mentioned chamomile powder into the retort, then add 0.45kg of cellulase and water, pressurize the water with a stone plate so that the water just soaks the chamomile powder, soak at room temperature for 4 hours, and obtain the extract;

[0050] (4) Distillation: Water vapor is introduced from the bottom of the distillation tank to heat the extract, and the extract is boiled and then extracted for 70 minutes to obtain mixed steam;

[0051] (5) Condensation: the mixed steam...

Abstract

The invention discloses a method for improving the extraction rate of chamomilia essential oil. The method comprises the following steps: drying chamomilia flowers in the sun, mechanically activating, adding cellulase and water, immersing for 2-4h, carrying out distilling extraction for 60-80min, condensing mixed water steam obtained after distillation, carrying out oil-water separation on a condensed oil and water mixture to obtain crude chamomilia oil, and carrying out extracting separation on the crude chamomilia oil to obtain the chamomilia essential oil. Mechanical activation treatment and immersion in cellulase are carried out before distilling extraction of the chamomilia essential oil, so the essential oil yield is improved, and the distillation time is shortened; and the method also has the advantages of simple operation, low cost and high product purity, and is very suitable for industrial production.

Description

technical field [0001] The invention relates to the field of essential oil extraction, in particular to a method for improving the extraction rate of chamomile essential oil. Background technique [0002] Chamomile (Matricariarecutita), also known as mother chrysanthemum, is an annual or perennial herb of the genus Matricaria in the Asteraceae family. It has a whole-plant aroma and contains volatile aromatic oils. Chamomile essential oil is the essential oil obtained by distilling chamomile flowers, branches and leaves. It has an excellent soothing effect and can relieve anxiety, tension, anger and fear, making people relaxed, patient and peaceful. Alleviates worry, calms the mind, and is great for insomnia. Add a few drops of chamomile essential oil to the hot water of the feet to achieve the purpose of promoting blood circulation and meridians, and can also achieve the effect of removing beriberi and foot odor. [0003] Chamomile essential oil has been widely used in dai...
