Embodiment 1

[0033] Example 1: Marker selection test

[0034] Take 2 equal portions of unflavored shredded tobacco from a certain brand of cigarettes, one portion is used as a blank sample, and the other portion is flavored according to the normal amount of flavoring. Dry the shredded tobacco sample at a temperature of about 40°C, grind it and pass it through a 40-mesh sieve, accurately weigh 25g of tobacco powder, and process it with a distillation extraction apparatus to obtain 40mL of dichloromethane extract Add 3g of anhydrous sulfuric acid Sodium, let it stand overnight, filter, concentrate in a rotary evaporator to 1mL, shake well, and take a sample for GC / MS analysis and identification. The analysis conditions are: HP-Innowax capillary column (60m×0.25mm×0.25μm); Gas: He, flow rate 1.0mL / min; inlet temperature: 260°C; box temperature: initial temperature 60°C, hold for 1min, increase to 250°C at 10°C / min, hold for 5min; transfer line temperature: 280°C; Energy: 70eV; EI ion source ...

Embodiment 2

[0036] Embodiment 2: Analytical method test

[0037] Put the shredded tobacco sample in a balance box (temperature 20°C±1, relative humidity 60%±3) to balance for 24 hours, and then use a fast solvent extraction apparatus to pre-treat the shredded tobacco sample. The extraction conditions are: take 6.0g shredded tobacco sample and put it into 34mL In the extraction pool, the extraction solvent is dichloromethane, the liquid supply pressure is set to 1500psi, the temperature is 130°C, the static extraction time is 5min, rinsed with 60% washing solution, the number of cycles of static extraction and solvent flushing is 1, and nitrogen gas is used to Purge for 100s. Obtain all the extracts and record the volume as VmL. Use a 10mL syringe to draw 2-5mL of the extract, filter it through a 0.45μm filter membrane, collect 1mL of the filtrate with a chromatographic sample, shake it up, and then conduct GC / MS analysis.

[0038] The analysis conditions of GC / MS are: HP-Innowax capilla...

Embodiment 3

[0053] Embodiment 3: Uniformity determination test

[0054] When the process parameters of the flavoring drum are set as follows: the flow rate is 6400kg / h, the air pressure of the atomizing medium is 0.3MPa, and the drum speed is 9r / min. After the equipment is running stably, 30 samples are continuously randomly selected from the exit of the aromatizing drum every 1 minute or so, each sample is about 10g, and placed in a plastic sealing tape. The determination of the marker menthol content in the shredded tobacco sample was carried out according to the method in Example 2, and the obtained results are shown in Table 5 below. It can be seen from Table 5 that under the operating state of the equipment, the uniformity of cigarette flavoring expressed by SD is 14.66.

Abstract

The invention relates to a detection method for the perfuming uniformity of cigarette shreds. The method sequentially comprises the following steps: A. confirming a label of characterization uniformity; B. sampling from an exit of a cigarette shred perfuming roller; C. balancing the cigarette shred sample obtained by sampling; D. pre-treating the cigarette shred sample by extraction with a rapid solvent extraction instrument, and preparing a filtering medium; E. carrying out gas chromatography and mass spectrum combined analysis on the filtering medium, taking the label as the analysis object, and adopting a selected ion scanning pattern; and F. calculating the content of the label in the cigarette shred sample, obtaining a standard deviation (SD), and reflecting the perfuming uniformity degree of the cigarette shred by the SD value. The detection method adopts the gas chromatography / mass spectrum instrument as the separation and analysis means, and quantifying-researches the uniformity of the perfuming procedure of the cigarette shreds, thereby confirming the uniformity of cigarette shred perfuming. The detection method is applied to the perfuming technological process in the cigarette production, thereby providing a practical and scientific method for the detection of the cigarette perfuming precision.

Description

technical field [0001] The present invention relates to a method for detecting the uniformity of flavoring in shredded cigarettes based on markers, in particular, to a method for detecting the accuracy and uniformity of flavoring in the process of flavoring in shredded cigarettes. The uniformity of cigarette flavoring determines the accuracy of cigarette flavoring. Background technique [0002] Flavoring is an important process in the production of shredded cigarettes. Its task is to accurately and evenly apply a certain amount of essence to shredded tobacco or shredded stems according to the requirements of production and formula. Obviously, the accuracy and uniformity of flavoring are important factors affecting the quality of cigarette products. At present, the testing of the accuracy of flavoring in the production process by various domestic cigarette companies is mainly based on the cigarette flavoring accuracy requirement of less than 0.5% stipulated in the "Cigarette...
