Embodiment 1

[0023] Take 30 g of Yunnan tobacco leaves, smash them through a 40-mesh sieve, and place them in a closed extraction tank. Take 500 g of BK31 low-order tobacco leaves and place them in the injection tank. Use a vacuum pump to make the extraction tank and injection tank reach the vacuum requirements and send them to the extraction tank. Inject 900mL of butane into the medium and completely immerse the Yunnan tobacco leaves. The soaking time is 30 minutes, the temperature is 40℃, the pressure is 0.6 MPa, and the extraction is performed 4 times. After the extraction, the liquid solvent is pumped into the evaporation tank, and the Yunnan tobacco leaves and the liquid solvent are separated. Perform constant temperature desolventization treatment, the liquid solvent desolves to obtain the extract containing the fat-soluble components of Yunnan tobacco leaves; the above subcritical fluid butane is pumped into the injection tank, the BK31 low-order tobacco leaves are completely submerged...

Embodiment 2

[0028] Granulate 200 g of fresh and dried red pepper, crush it through a 100-mesh sieve with a particle size of 2 mm, and place it in an extraction tank; take 500 g of natural fiber fabric and wind it on a distributor and place it in an injection tank; use a vacuum pump to make the extraction tank and The injection tank meets the vacuum requirement, and subcritical fluid dimethyl ether is injected into the extraction tank as the extraction solvent. The extraction solvent completely immerses the pepper particles. The mass-volume ratio of the pepper particles and the extraction solvent reaches 1:20 g / ml. The soaking time is 15 minutes, the temperature is 30°C, the pressure is 0.55 MPa, and the extraction is repeated 3 times; after the extraction, the pepper particles and the liquid solvent are separately treated at a constant temperature, and the liquid solvent is removed to obtain an extract containing the fat-soluble components of the pepper particles; The above subcritical flui...

Embodiment 3

[0031] Take 150 g of sandalwood extract and dry it until the moisture content is below 4%. After crushing, pass a 50-mesh sieve and place it in the extraction tank, and put a whole 1 kg pear wood in the injection tank; use a vacuum pump to make the extraction tank It meets the vacuum requirement with the injection tank, and injects the subcritical fluid butane into the extraction tank as the extraction solvent. The extraction solvent completely immerses the sandalwood extract and then performs subcritical extraction. The mass volume ratio of sandalwood to extraction solvent is 1:10 g / ml, the extraction time is 10 minutes, the temperature is 35℃, the pressure is 0.1 MPa, and the extraction cycle is 3 times; after the extraction, the sandalwood and the liquid solvent are subjected to constant temperature desolvation treatment, and the liquid solvent desolves to obtain sandalwood grease. Extraction of soluble components; using the above subcritical fluid butane as an injection solv...

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 method for subcritical injection of fat-soluble components that does not damage product activity, can be industrialized and mass-produced, and can change the internal components of materials. Background technique [0002] At present, the extraction of fat-soluble components in samples of wood, food, tobacco, medicine, food and health care mainly includes steam distillation, ethanol reflux, and supercritical CO 2 Law etc. The effective components 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, but the equipment is expensive and difficult to maintain, and it is not suitable for industrial production. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings in the prior art and pro...
