Embodiment 1

[0019] Embodiment 1, the preparation method of this lavender absolute oil is obtained according to the following steps: the first step, choose lavender extract, and the ethanol aqueous solution that the mass percentage content is 93% to 98% by lavender extract and mass percentage is 0.9 : 1.8 to 1.1: 2.2 After shaking and mixing, the mixed solution is obtained; in the second step, the frozen mixed solution is obtained after standing at -5°C to -10°C for 2 hours to 5 hours; in the third step, the frozen mixed solution is After 300 order to 400 order filter cloth filter, obtain filtrate after carrying out suction filtration with Buchner funnel again; The 4th step, filtrate obtains lavender absolute oil of the present invention after reclaiming ethanol aqueous solution.

Embodiment 2

[0020] Embodiment 2, the preparation method of this lavender absolute oil is obtained according to the following steps: the first step, choose lavender extract, and the ethanol aqueous solution that the mass percentage content is 93% to 98% by lavender extract and mass percentage is 0.9 : 1.8 to 1.1: 2.2 After shaking and mixing, the mixed solution is obtained; the second step is to stand the mixed solution at -5°C or -10°C for 2 hours or 5 hours to obtain the frozen mixed solution; the third step is to freeze the mixed solution through After 300 order or 400 order filter cloths filter, obtain filtrate after carrying out suction filtration with Buchner funnel again; The 4th step, filtrate obtains lavender absolute oil of the present invention after reclaiming ethanol aqueous solution.

Embodiment 3

[0021] Embodiment 3, as above-mentioned embodiment optimization, this lavender extract is obtained by the following method: the first step, selects lavender fresh flowers; Second step, puts lavender fresh flowers into subcritical extraction kettle, is 2Mpa to 4Mpa at extraction pressure , under the conditions of extraction temperature 30°C to 40°C, the extraction agent R134a is introduced into the subcritical extraction kettle through a booster pump with a flow rate of 8 g / min to 12 g / min for continuous extraction for 1 hour to 2 hours to obtain lavender fluid; the third The first step is to flow the lavender fluid from the subcritical extraction kettle into the subcritical separation kettle and lower it to normal temperature for separation to obtain lavender extract.

Abstract

The invention relates to the technical field of lavender absolute oil, in particular to lavender absolute oil and a preparation method thereof. The method comprises the steps that firstly, a lavender extract is selected, and the lavender extract and an ethanol solution with the mass percentage being 93-98% are vibrated and mixed on the basis of the mass ratio being 0.9:1.8-1.1:2.2 to obtain a mixed solution; secondly, the mixed solution is subjected to standing under the temperature of 5-10 DEG C for 2-5 h to obtain a freezing mixture. The lavender absolute oil is extracted by adopting an extract extracted by a subcritical device through a later separation and extraction technology, the lavender oil contains volatile and non-volatile aromatic hydrocarbon compounds, the content of linalool and linalyl acetate in the extracted absolute oil are increased remarkably, the content of camphor is lowered, the top note, the basic note and the end note are better than those of absolute oil obtained through atmospheric distillation, the fragrance is fuller, long and stable, small molecule compound losses are small, and the lavender absolute oil is the best raw material for blending top-grade perfume and highest-grade essential oil.

Description

technical field [0001] The invention relates to the technical field of lavender absolute, and relates to a lavender absolute and a preparation method thereof. Background technique [0002] Liu Xiaocao from South China University of Technology and others carried out enzymatic hydrolysis-subcritical water extraction of active ingredients of ginger, the results show that: enzymatic hydrolysis-subcritical water extraction process, the most suitable temperature is 120 ℃; the best extraction pressure is 8MPa; The amount of enzyme added is 0.3%; the amount of feed is 100%; the extraction time is 20 minutes; the yield of active ingredients in sand ginger essential oil is about 10% higher than that of SWE method; The best process conditions are: static extraction, extraction time 30min, pressure 2 MPa, 100-150°C continuous temperature program, petroleum ether as extraction solvent, extraction 2 times; under this condition, the yield of onion essential oil is 0.362% , the content of ...
