Problems solved by technology

[0003] At present, various cigarette companies lack detection methods for important aroma substances in shredded tobacco, and it is difficult to accurately quantify important aroma substances in shredded tobacco
The evaluation methods currently used for the accuracy and uniformity of flavoring are basically deduced and calculated from a theoretical point of view, or adjusted and rectified from the perspective of processing equipment, without fundamentally improving the uniformity of flavoring. It is difficult to effectively monitor the flavoring process through quantitative research

Embodiment 1

[0021] A detection method for simultaneously determining several aroma substances in shredded cigarette tobacco, said several aroma substances refer to furanone, isopentyl isovalerate, maltol, nicotinone, menthol, ethyl maltol, 5-hydroxy Methylfurfural, Anethole. The method of the present invention uses solvent vibration extraction and gas chromatography-mass spectrometry to simultaneously measure the contents of several aroma substances in shredded cigarette tobacco, comprising the following steps:

[0022] Prepare test samples: samples are taken from flavored shredded tobacco or unflavored shredded tobacco or tobacco essence in the cigarette shredding process.

[0023] When preparing to test samples, continuously sample each batch of shredded tobacco 30 times, each sampling interval is 1min, each time sampling is 100g, one batch of samples is taken every day, and a total of 5 batches are taken in 5 days, and mixed as test samples .

[0024] ② Prepare standard solutions o...

Embodiment 2

[0029] For the simultaneous determination of furanone, isopentyl isovalerate, maltol, nicotine, menthol, ethyl maltol, 5-hydroxymethylfurfural and anethole in cut tobacco It uses solvent vibration extraction and gas chromatography-mass spectrometry to determine several important aroma substances in cigarette shred samples or flavors used in samples.

[0030] The method of the invention first screens the pretreatment experimental conditions, and optimizes the experimental parameters. Specifically include the following steps:

[0031] ①Preparation of samples for testing: samples can be taken from any of flavored shredded tobacco, unflavored shredded tobacco, and tobacco essence in the cigarette making thread process. In this embodiment, flavored cut tobacco is selected. The sampling position of the flavored shredded tobacco sample can be collected at a fixed position after the exit of the flavoring drum on the silk making line. After the operation is stable in each batch, cont...

Embodiment 3

[0050] Prepare chromatographically pure solvents: dichloromethane, absolute ethanol, methyl tert-butyl ether, n-hexane, standard products: furanone (CAS: 3658-77-3), isoamyl isovalerate (CAS: 659-70 -1), maltol (CAS: 118-71-8), nicotine (CAS: 4883-60-7), menthol (CAS: 89-78-1), ethyl maltol (CAS: 4940-11 -8), 5-Hydroxymethylfurfural (CAS: 67-47-0), anethole (CAS: 104-46-1), naphthalene (CAS: 91-20-3), the purity is not less than 99%. There is no shredded tobacco added to a certain brand of cigarettes.

[0051] Prepare equipment and instruments: electronic balance, ultrasonic cleaning machine, oscillator, rotary evaporator, 7890-5975C gas chromatography mass spectrometry instrument, capillary column (elastic capillary column HP-5MS column, the specification is 30m×0.25mmi.d×0.25 μm i.d.). These equipment instruments all can adopt prior art equipment instrument.

[0052] Preparation of working standard solution: mix furanone, isopentyl isovalerate, maltol, nicotine ketone, me...

Abstract

The invention provides a detection method for simultaneously determining a plurality of flavor substances in cigarette cut tobaccos. The flavor substances comprise furanone, isoamyl isovalerate, maltol, tabanone, menthol, ethyl maltol, 5-hydroxymethyl furfural and anethole. The method utilizes a solvent oscillation extraction method and a gas chromatography and mass spectrometry method to simultaneously determine the contents of a plurality of the flavor substances in the cigarette cut tobaccos; and the contents of a plurality of the flavor substances in a detection sample is calculated by the steps of preparing the detection sample, preparing a standard solution of a plurality of the flavor substances, preparing a sample solution and carrying out gas chromatography and mass spectrometry analysis. The method disclosed by the invention can accurately measure the contents of a plurality of the important flavor substances in a cigarette cut tobacco sample and is used for effectively evaluating the flavoring uniformity of the cigarette cut tobaccos, so as to provide the powerful technical support to a cigarette tobacco primary process. The method disclosed by the invention has the advantages of rapidness and convenience, simplicity in operation, good repeatability and high assay determination flexibility; and the recycling rate of a plurality of the important flavor substances can meet the requirements.

Description

technical field [0001] The invention relates to the technical field of tobacco detection. Background technique [0002] In the cigarette manufacturing process, the silk-making process has many procedures, a long process, complex processing methods, and high technological requirements, and flavoring is one of the important processes. Accurate and even application to cut tobacco or stems. Obviously, the accuracy and uniformity of flavoring are important factors affecting the quality of cigarette products, and the content of important flavoring substances in shredded tobacco is a very important index for evaluating the uniformity of flavoring in the shredded cigarette process. Therefore, monitoring the uniformity index of flavoring to improve the accuracy and uniformity of flavoring in the cigarette shredded process is an important part of improving the stability and controllability of the cigarette shredded process, and it is also an important part of continuously improving c...
