Embodiment 1

[0027] A method for improving the extraction rate of valerian essential oil, the steps are as follows:

[0028] (1) the valerian root of gathering is dried, and its moisture content is 8.5%;

[0029] (2) mechanical activation: add the dried valerian root in the stirring ball mill, and mechanically activate it for 7 minutes at a rotating speed of 90r / min to obtain the valerian root powder;

[0030] (3) Enzymolysis treatment: use compound enzyme to treat valerian root powder at 45°C for 2.5 hours;

[0031] (4) Distillation: feed water vapor from the bottom of the retort to heat the extract, and extract for 2 hours after the extract boils to obtain mixed steam;

[0032] (5) Condensation: the mixed steam obtained above is condensed through a condenser, and the oil-water mixture is obtained after condensation;

[0033] (6) oil-water separation: the oil-water mixture obtained by condensation is carried out oil-water separation through the oil-water separator to obtain valerian cru...

Embodiment 2

Abstract

The invention discloses a method for improving the extraction rate of valeriana officinalis essential oil, and belongs to the field of essential oil extraction. The method comprises the following steps: drying valeriana officinalis, performing mechanical activating treatment, and then performing enzymolysis treatment through compound enzyme; performing distillation extraction on treated raw materials for 2 to 3h, condensing mixed water vapor obtained through distillation, and performing separation on an oil water mixture obtained through condensing, so as to obtain valeriana officinalis crudeoil; performing extraction separation on the valeriana officinalis crude oil, so as to obtain the valeriana officinalis essential oil. The method has the advantages that before distillation extractionof the valeriana officinalis essential oil, mechanical activating treatment and enzymolysis treatment are firstly performed, and plant cell walls are destroyed and particles are refined under the action of mechanical force; the structure and constituents of raw materials are changed through enzymolysis treatment, and the yield of essential oil is improved, potential effective aroma constituents in the raw materials can be further released; the method further has the advantages of high simpleness in operation, mild reaction condition, high selectivity and short extraction time, and is applicable to industrial production.

Description

technical field [0001] The invention belongs to the field of essential oil extraction, and relates to a method for improving the extraction rate of valerian essential oil. Background technique [0002] Valerian (Valeriana off icinalis L.) belongs to the Valerianaceae (Valerianaceae) genus Valeriana (Valeriana L.) perennial herb. Rheumatism arthralgia, epigastric distension and pain, bruises embolism. Valerian contains volatile aromatic oils and is a spice plant with great development value. The volatile oil of valerian is mainly composed of terpenes, which contain alkenes, ketones, alcohols, esters and ethers. Among them, bornyl acetate, camphene and pinene are main components, and the content of bornyl acetate is about 30%. The root and stem of valerian root and stem contain 1.5% to 6% oil, but the extraction rate of valerian root in China is generally 0.2% to 0.75%, which is quite different from the oil content of valerian root. [0003] Valerian essential oil is an im...
