Problems solved by technology

Yet this method is only applicable to the raw material that the relative percentage content of linalool is higher, and the final productive rate of this method is not high simultaneously
[0016] However, the purification step usually cannot stand alone and must rely on a suitable extraction step to achieve better purification effect
[0017] For the use of essence, the volatile oil extract of green pepper in the prior art still generally has the technical defect that the final yield is low and the proportion of linalool content is not high

Embodiment 1

[0061] figure 1 It is a subcritical extraction device according to a specific embodiment of the present invention. Among them, 1 is a solvent storage tank; 2 is an extraction tank; 3 is a separation tank; 4 is a collection tank; 5 is a metering pump; 6 is a compressor; 7 is a condenser; 8 is a hot water tank; 9 is a hot water pump; 10 11 is a thermometer; 12 is a spherical valve; 13 is a vacuum pump; 14 is a control system.

[0062] Dried green peppercorns (place of origin: Laiwu, Shandong) to moisture content ≤ 10%, and crushed to a particle size of 50 mesh to obtain green peppercorn powder. Weigh 1kg green pepper powder and pack it into a 200-mesh material bag with an aperture, put it into the extraction kettle 2 and seal it. The first extraction step and the second extraction step were performed separately.

[0063] The first extraction step is as follows: use the vacuum pump 13 to evacuate the extraction kettle 2 to make the vacuum degree of the extraction kettle 2 reac...

Embodiment 2

[0066] Dried green peppercorns (place of origin: Laiwu, Shandong) to moisture content ≤ 10%, and crushed to a particle size of 40 mesh to obtain green peppercorn powder. Weigh 1kg green pepper powder and pack it into a 200-mesh material bag with an aperture, put it into the extraction kettle 2 and seal it. The first extraction step and the second extraction step were performed separately.

[0067] The extraction conditions of the first extraction step are as follows: the solvent is composed of dimethyl ether and entrainer 95% ethanol at a volume ratio of 3:1; the liquid-solid ratio is 5:1mL / g; the extraction pressure is 0.40MPa; the extraction temperature is 35°C ; Extraction time is 30min; All the other are with extraction embodiment 1.

[0068] The extraction conditions of the second extraction step are as follows: the solvent is propane; the liquid-solid ratio is 20:1mL / g; the extraction pressure is 1.0MPa; the extraction temperature is 30°C; the extraction time is 60min; ...

Embodiment 3

[0070] Dried green peppercorns (place of origin: Laiwu, Shandong) to moisture content ≤ 10%, and crushed to a particle size of 60 mesh to obtain green peppercorn powder. Weigh 1kg green pepper powder and pack it into a 200-mesh material bag with an aperture, put it into the extraction kettle 2 and seal it. The first extraction step and the second extraction step were performed separately.

[0071] The extraction conditions of the first extraction step are: the solvent is composed of dimethyl ether with a volume ratio of 5:1 and entrainer 95% ethanol; the liquid-solid ratio is 6:1mL / g; the extraction pressure is 0.45MPa; the extraction temperature is 45°C ; Extraction time is 20min; All the other are with extraction embodiment 1.

Abstract

The invention discloses a preparation method of green prickleyash volatile oil. The preparation method comprises extraction: taking green prickleyash powder as a raw material, and obtaining raw material volatile oil through a subcritical extraction method, and purification: uniformly mixing the raw material volatile oil and 1, 3-propylene glycol and carrying out molecular distillation to obtain purified green prickleyash extract. In addition, the invention also discloses corresponding green prickleyash extract. According to the method, the final yield is between 3.6% and 4.4%, and meanwhile, the linalool content is correspondingly high.

Description

technical field [0001] The invention belongs to the technical field of biochemical products, and relates to a green and environment-friendly green pepper extract and a preparation method thereof, more specifically, to a green pepper volatile oil extract and a preparation method thereof. Background technique [0002] Green Zanthoxylum bungeanum is a plant of the genus Zanthoxylum Bungeanum Maxim, and generally said Zanthoxylum bungeanum refers to the dried fruit of this type of plant. There are about 250 species of this genus in the world, distributed in tropical and subtropical regions such as Asia, Africa, South America and Oceania. my country is one of the countries with the largest pepper planting area in the world, mainly distributed in Sichuan, Chongqing, Gansu, Shandong and Hebei provinces. [0003] The most common use of green Zanthoxylum bungeanum is as a condiment. It is a favorite spice of our people and is known as one of the eight great flavors. In addition to ...
