Abstract
The invention relates to a method for preparing tobacco flower absolute oil by using supercritical CO2 extraction. The method comprises the following steps of: a, putting a tobacco flower raw material into an extraction kettle; b, injecting supercritical CO2 into the extraction kettle, and extracting for 60-240 minutes under the conditions that the extraction pressure is 20-50 MPa and the extraction temperature is 35-55 DEG C; and c, introducing CO2 fluid dissolved with an aroma component into a separation kettle, reducing the pressure and raising the temperature to separate the aroma component of the tobacco flower out, discharging the separated part from the bottom of the separation kettle to obtain the tobacco flower absolute oil, and introducing the CO2 into the extraction kettle for recycling. According to the method, the CO2 is adopted as a main solvent and can be operated at normal temperature, so that the process is simple, the operation is convenient, the residue of an organic solvent can be avoided, and oxidation and decomposition of thermosensitive components and chemical unstable components can be effectively prevented.
Description
Technical field
The present invention relates to natural baccy plant perfume extractive technique field.
Background technology
Along with the reduction of tar content, low-coke tar cigarette exists smoke thin out, and fragrance weakens, and cigarette product loses original style, is difficult to the problem of being accepted by the human consumer.So in the cigarette lowering harm and decreasing coking, promote and improve flue gas concentration and fragrance, be a urgent problem that solves, the mode by flavoring and casing can remedy the insufficient fragrance part on the cigarette tobacco leaf formulation.
Chinese invention patent 90107606,93101941,93101746 discloses technology, flue-cured tobacco bud cream and using method thereof and burley bud sweet paste and the using method thereof of extracting balm from tobacco bud, main technique is: with bud dry in the shade, with after the alcohol pre-treatment, with the mother liquor normal pressure that produces in the production process, middle temperature, high temperature, high pressure two steps extraction.Extraction liquid filters, concentrates, perfuming gets balm.Collection slag adding distil water extracting twice, mother liquor returns makes extraction agent.These technologies belong to traditional solvent extraction techniques category, and extraction efficiency is lower, and temperature is higher, and aroma component loses in a large number, and leave organic solvent residual.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of CO is provided
2Can operate at normal temperatures, technology is simple, and is easy to operate, can avoid organic solvent residue, can effectively prevent oxidation and the decomposition of thermo-sensitivity composition and chemically unstable composition, is raw material with the tobacco, utilizes supercritical CO
2Abstraction technique prepares the method for tobacco extrait.
Purpose of the present invention is achieved through the following technical solutions:
Utilize supercritical CO
2Extraction prepares the method for tobacco extrait, and method steps is as follows:
A, the tobacco raw material is packed in the extraction kettle;
B, with the CO of supercritical state
2Injecting extraction kettle, is 20～50MPa in extracting pressure, under the condition that extraction temperature is 35～55 ℃, and extraction 60～240min;
C, be dissolved with the CO of aroma component
2Fluid enters separating still, heats up by step-down the aroma component of tobacco is separated, and the part self-separation still bottom of separating is discharged and namely obtained tobacco extrait, CO
2Entering extraction kettle recycles.
Tobacco raw material of the present invention is one or more in flue-cured tobacco bud, burley tobaccos bud, Turkish tobaccos bud, the region airing fireworks flower bud.The present invention is in extraction kettle that the tobacco raw material is packed into the time, and can add concentration is that 60～95% edible ethanols are as carrying solvent.
Supercritical CO
2Abstraction technique can be near room temperature and CO
2Extract under gas shrouds, effectively prevent oxidation and the loss of heat-sensitive substance.The present invention adopts supercritical CO
2The method of aroma component during extracted tobacco is spent, can effectively prevent oxidation and the decomposition of tobacco thermo-sensitivity composition and chemically unstable composition, the aroma component that keeps tobacco in extract extracts the material of high boiling point, low volatility, easily pyrolysis under far below its boiling temperature.Utilize CO
2Be in to have under the supercritical state and extract and the distillation dual function, can avoid organic solvent residue, significantly improve production efficiency.Technology of the present invention is simple, and is easy to operate.In addition, owing in extraction process, also can add and carry the agent edible ethanol, improved the middle aroma component of tobacco at supercritical CO
2Solubleness in the fluid, thus the multiple aroma component in the tobacco is fully extracted, improved extraction efficiency.And CO
2Cheap and easy to get, general recyclable about 80%, but save energy.
The present invention takes full advantage of the tobacco own resources, and exploitation tobacco endogenous essence spice for cigarette is given the style and features of cigarette uniqueness, provides space and using value widely for developing unique essence spice for cigarette.The present invention is different with traditional extraction technique, is to adopt CO
2As main solvent, add edible ethanol as carrying solvent, prepared absolute oil is brown solution, its enriched material is the bright semi-fluid of sorrel clarification.
