[0054] 1. Materials

[0055] 1.1 Materials, reagents and instruments

[0056] The samples of honey-sweet, light-sweet and mint-flavored popping beads produced by Guangzhou Xingye Biotechnology Co., Ltd. are numbered A-C respectively.

[0057] n-Hexane is chromatographically pure.

[0060] 2.1 Processing of samples

[0061] Grind the popcorn sample with a mortar, and take the contents of the popcorn and pass through a 0.45 μm organic phase needle filter membrane for later use. Use a pipette gun to accurately pipette 0.5mL of the content of the popping beads into a 50mL conical flask with a stopper, add ...

Embodiment 2

[0088] 1. Materials, reagents and instruments are the same as in Example 1.

[0089] 2.1 Processing of samples

[0090] Grind the popcorn sample with a mortar, and filter the contents of the popcorn through a 0.22 μm organic needle filter membrane for later use. Use a pipette gun to accurately pipette 0.3mL of the contents of the popping beads into a 50mL Erlenmeyer flask with a stopper, add 3.0mL of n-hexane solution containing n-heptadecane, shake and extract for 20min, after standing still, take the supernatant and filter it through the organic phase After the membrane passes through the membrane, it is analyzed by gas chromatography-mass spectrometry. The concentration of the n-hexane solution containing n-heptadecane is 0.12 mg / mL, so the ratio of the content of the popping beads to the internal standard in the internal standard solution is 1 mL: 1.2 mg.

[0099] Grind the popcorn sample with a mortar, and filter the contents of the popcorn through a 0.22 μm organic needle filter membrane for later use. Use a pipette gun to accurately pipette 1.0mL of the contents of the popping beads into a 50mL Erlenmeyer flask with a stopper, add 10.0mL of n-hexane solution containing n-heptadecane, shake and extract for 60min, after standing still, take the supernatant and filter it through the organic phase After passing through the membrane, it was analyzed by gas chromatography-mass spectrometry. The concentration of the n-hexane solution containing n-heptadecane is 0.2mg / mL, so the ratio of the content of the popping beads and the internal standard in the internal standard solution is 1mL: 2mg.

Abstract

The invention relates to a method for evaluating the intrinsic quality stability of a cigarette blasting bead. The method comprises the following steps: grinding a plurality of batches of cigarette blasting bead samples separately, carrying out filtering to obtain blasting bead contents, adding an internal standard solution into the blasting bead contents, taking a supernatant after extraction, and filtering the supernatant to obtain filtrate, wherein the ratio of the blasting bead contents to internal standard substances in the internal standard solution is 1mL:(0.5-2.0)mg; carrying out gas chromatography-mass spectrometry analysis on the filtrate, taking an internal standard peak as a reference peak, determining a common peak, calculating a relative retention time alpha and a relative peak area S value of a chromatographic peak in the cigarette blasting bead sample, and establishing a chromatographic fingerprint of each blasting bead content sample; obtaining a euclidean distance, aeuclidean distance ratio and similarity by using the relative peak area S value of each component in each batch of cigarette blasting bead samples, and evaluating the intrinsic quality stability of the cigarette blasting bead. The method provided by the invention can comprehensively analyze the intrinsic quality of the cigarette blasting bead and reflect the fluctuation of the intrinsic quality.

Description

technical field [0001] The invention belongs to the technical field of tobacco materials, and in particular relates to a method for evaluating the internal quality stability of popping beads for cigarettes. Background technique [0002] The technology of adding popping beads for cigarettes is to implant one or more flavor capsules that are easy to pinch and break during the production process of the filter tip, so as to realize the artificial and controllable release of characteristic flavor during the smoking process of cigarettes, and reduce the impact of the external environment on the flavor and Flavor loss caused. Popping beads for cigarettes play an important role in improving the taste of cigarettes, compensating and enhancing the aroma of cigarettes, and highlighting the style of cigarettes. More and more cigarette manufacturers are committed to the research and development of popping beads cigarettes. [0003] At present, the research on popping beads for cigarette...
