Problems solved by technology

[0004] Because the popping beads for cigarettes are limited by product characteristics (organic solvents are required to wrap various spice liquids), the moisture content is low, and the diameters and rubber thicknesses are different. External force crushing is required during testing, and more samples are lost during pretreatment operations. , so the moisture content is not easy to detect
At present, there is no report on the detection method of moisture content of popping beads for cigarettes

Embodiment Construction

[0031] The invention provides a method for detecting the moisture content of the quick-fried pearls for cigarettes. The moisture content in the quick-fired pearls is obtained through capillary column separation, gas chromatography-thermal conductivity detector (GC-TCD) analysis, and internal standard method for quantification. The limit of quantification, standard addition recovery, and intraday (inter) precision experiments were verified for the method. The results showed that the recoveries of high, medium and low standards were between 98.95% and 104.48%; the quantitative limit of the method was 0.0577mg / mL ; The intraday precision is 3.47%, and the interday precision is 4.05%.

Abstract

The invention discloses a method for detecting moisture content of explosion beads for cigarettes. According to the method, explosion bead samples for cigarettes are pretreated, separated by a capillary column and analyzed by a gas chromatography-thermal conductivity detector method; each sample is measured twice in parallel; in each experiment, a blank sample is needed; and quantification is carried out by adoption of an internal standard method so as to obtain moisture contents in the beads. The detection method is verified to have an adding standard recovery rate of 98.95%-104.48%, a methodquantification limit of 0.0577 mg / mL, an intraday precision of 3.47% and a day-to-day precision of 4.05%. The method is simple in pre-treatment operation and good in reproducibility, and is capable of correctly analyzing and quantifying explosion bead samples with low moisture contents.

Description

technical field [0001] The invention belongs to the technical field of tobacco materials, and in particular relates to a method for detecting the moisture content of popping beads for cigarettes. Background technique [0002] "Popping bead" refers to a small liquid glue bead embedded in the tobacco filter rod. It wraps liquids of different types of flavors to realize the artificially controllable release of characteristic flavors during cigarette smoking. During the burning process of cigarettes, exogenous flavors can be directly transferred to the smoke, which has the characteristics of less flavor loss and unique sensory style. It has been widely used in cigarette products. [0003] As a technical means of "increasing flavor and moisturizing" cigarettes, "popping beads" can not only endow cigarettes with flavor and style, affect the release of seven harmful components, but also achieve the effect of moisturizing smoke through the transfer of water. The study found that t...
