Embodiment 1

[0023] Take 30 g of Yunnan tobacco leaves, crush them and pass through a 40-mesh sieve, put them in a closed extraction tank, take 500 g of BK31 low-grade tobacco leaves and put them in an injection tank, use a vacuum pump to make the extraction tank and the injection tank meet the vacuum requirements, and pour into the extraction tank Inject 900 mL of butane into the water, and completely immerse the Yunnan tobacco leaves. The soaking time is 30 minutes, the temperature is 40 ° C, the pressure is 0.6 Mpa, and the extraction is performed 4 times. Carry out constant temperature precipitating treatment respectively, liquid solvent desolventizing can obtain the extract containing the fat-soluble components of Yunnan tobacco leaves; pump the above-mentioned subcritical fluid butane into the injection tank, completely submerge the BK31 low-grade tobacco leaves, supplement butane as the injection solvent, Make the mass-volume ratio of the obtained extract and the BK31 low-grade tobac...

Embodiment 2

[0028] 200 g of fresh dried red peppers were granulated, crushed with a particle size of 2 mm and passed through a 100-mesh sieve, and placed in an extraction tank; 500 g of natural fiber fabric was wound on a distributor and placed in an injection tank; the extraction tank was separated from the extraction tank by a vacuum pump The injection tank reaches the vacuum requirement, and injects subcritical fluid dimethyl ether into the extraction tank as the extraction solvent, the extraction solvent completely submerges the pepper particles, the mass volume ratio of the pepper particles and the extraction solvent reaches 1:20 g / ml, and the soaking time is For 15 minutes, the temperature is 30°C, the pressure is 0.55 Mpa, and the extraction is repeated 3 times; after the extraction is completed, the capsicum granules and the liquid solvent are subjected to constant temperature desolvation treatment, and the liquid solvent is desolvated to obtain an extract containing the fat-soluble...

Embodiment 3

[0031]Get 150 g of sandalwood extract and dry it until the moisture content is below 4%, put it in the extraction tank after crushing it through a 50-mesh sieve, and put a whole piece of 1 kg of pear wood in the injection tank; use a vacuum pump to make the extraction tank Meet the vacuum requirements with the injection tank, and inject the subcritical fluid butane into the extraction tank as the extraction solvent. The extraction solvent will completely submerge the sandalwood extract and perform subcritical extraction. The mass volume ratio of sandalwood and extraction solvent is 1:10 g / ml, the extraction time is 10 minutes, the temperature is 35°C, the pressure is 0.1 Mpa, and the extraction is repeated 3 times; after the extraction, the sandalwood and the liquid solvent are subjected to constant temperature precipitation treatment, and the liquid solvent precipitation can obtain the sandalwood resin containing The extract of soluble components; the above-mentioned subcritic...

Abstract

The invention relates to the field of subcritical extraction and injection, specifically to a liposoluble component subcritical injection method which will not destroy activity of a product, is suitable for industrial large-scale production and helps realize alternation of components in a material. The method of the invention comprises the following steps: 1) pretreatment: drying, crushing and sieving; 2) extraction: placing the pretreated sample into an extraction tank, adding a subcritical fluid as an extraction solvent, extracting under a certain condition, carrying out constant-temperature desolvation after extraction, and desolventizing a liquid solvent to obtain a sample extract; 3) reversed extraction: placing the above extract and a material which needs to undergo subcritical injection into an injection tank, adding an injection solvent and carrying out subcritical injection under a certain condition, and carrying out constant-temperature desolvation treatment on the injection tank after the injection so as to obtain a material which has undergone injection treatment.

Description

technical field [0001] The invention relates to the field of subcritical extraction and injection, in particular to a subcritical injection method of a fat-soluble component that does not destroy product activity, can be industrially produced on a large scale, and realizes the change of internal components of materials. Background technique [0002] At present, the extraction of fat-soluble components in samples such as wood, food, tobacco and medical food health care mainly includes steam distillation, ethanol reflux method, supercritical CO2 method, etc. The active ingredients of the steam distillation method are easily destroyed and volatilized, and time-consuming; while the supercritical extraction method, although the biological activity is not easily destroyed, the equipment is expensive and maintenance is difficult, so it is not suitable for industrial production. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies...
