Problems solved by technology

Chromatography-mass spectrometry has certain requirements on the extraction solvent, which is required to have good volatility, and low-toxic anhydrous ethanol is usually used, while tobacco flavors are mostly in the form of paste or viscous, with poor fluidity and difficult to dissolve in this Organic solvents, resulting in low extraction efficiency of characteristic components, fewer effective chromatographic peaks, and difficulty in accurately identifying spices, increasing the difficulty of cigarette flavoring; at the same time, the extract has high sugar content and many impurities, which are easy to stick and damage the sampling needle. Serious pollution to the chromatographic system

Embodiment 1

[0058] 1. Weigh 5g of commercially available tree moss extract and dissolve it with 100mL of 50% ethanol aqueous solution to obtain a spice diluent for later use;

[0059] 2. Measure 40mL AB-8 macroporous adsorption resin (weak polar resin) into the extraction kettle, first rinse the resin with 100mL absolute ethanol at a flow rate of 2mL / min, and then pump in deionized water at a flow rate of 1mL / min Rinse the resin with water until the effluent is clear; pump all the fragrance diluents into the activated macroporous adsorption resin at a fluidity of 0.5mL / min, pour in liquid carbon dioxide, and at the same time pump anhydrous at a flow rate of 0.1mL / min Ethanol, under the conditions of 10MPa and 55°C, open the pressure reducing valve, and the ethanol carrying the dissolved aroma components is continuously taken out by carbon dioxide at a flow rate of 1.5L / min, and continuously collected for 1 hour. At the same time, the carbon dioxide gas is separated and liquefied after refr...

Embodiment 2

[0069] 1. Weigh 10g of commercially available sea buckthorn extract and dissolve it with 120mL of deionized water to obtain a spice diluent for later use;

[0070] 2. Measure 50mL HPD-450 macroporous resin (medium polar resin) into the extraction kettle, first rinse the resin with 80mL absolute ethanol at a flow rate of 2.5mL / min, and then use 50mL deionized water at a flow rate of 1mL / min. The resin was rinsed with a flow rate; all the fragrance diluent was pumped into the activated macroporous resin at a flow rate of 0.8mL / min, liquid carbon dioxide was introduced, and at the same time, a volume ratio of 3:7 was pumped at a flow rate of 0.2mL / min. Alkane ethanol mixed solvent, under the conditions of 10MPa and 50℃, open the pressure reducing valve, the mixed solvent carrying the dissolved aroma components is continuously taken out by carbon dioxide at a flow rate of 1L / min, and continuously collected for 1.0h. At the same time, the carbon dioxide gas is separated after refrig...

Abstract

The invention relates to the technical field of analysis and detection of tobacco flavors, in particular to a tobacco flavor characteristic component analysis method and a pretreatment method thereof. The pretreatment method for characteristic component analysis of the tobacco flavor comprises the following steps: dissolving the tobacco flavor with a solvent to prepare a flavor diluent; carrying out adsorption treatment on the perfume diluent by adopting macroporous adsorption resin; carrying out supercritical elution on the macroporous adsorption resin subjected to adsorption treatment, and collecting eluent, so as to obtain the pretreated tobacco flavor liquid. According to the pretreatment method, the tobacco flavor is dissolved without being limited by a solvent and a material-liquid ratio; by utilizing the extraction and carrying capacities of fluid carbon dioxide extraction, the obtained aroma components are comprehensive, the enrichment efficiency is high, and the method is environment-friendly and non-toxic; the using amount of an eluent is small, the obtained eluent does not need to be concentrated, the loss of flavor components is effectively avoided, and the concentration of the flavor components is high; the use of a large amount of organic solvents is avoided, the method is environment-friendly, the extract liquor is free of impurities, and the pollution to instruments is reduced.

Description

technical field [0001] The invention relates to the technical field of analysis and detection of tobacco flavors, in particular to a method for analyzing characteristic components of tobacco flavors and a pretreatment method thereof. Background technique [0002] Tobacco flavors such as extracts, infusions, tinctures, extracts and other extracts are widely used in cigarette additions. These natural flavor materials can coordinate with the tobacco flavor, improve the smell, increase the sweetness, and inhibit irritation, pungency, etc. To enhance the smoking comfort of cigarettes, natural plants are extracted with strong polar solvents. This type of fragrance is a viscous or paste-like fragrance obtained by filtration and concentration, so the content of polar solvents such as water and propylene glycol is relatively high, and the content of fragrance components is relatively low. [0003] In cigarette flavoring and quality control, it is necessary to analyze flavor componen...
