Embodiment 1

[0051] 1. Sample pretreatment

[0052] The adsorption sampling tube filled with adsorbent is aged on an aging instrument. Under a nitrogen atmosphere with a purity of ≥99.999%, the nitrogen pressure is maintained at 15-25 psi and aged at 280-320°C for 20-40 min. The two ends of the aged adsorption sampling tube are sealed with copper caps for use. The adsorption sampling tube is a composite-filled adsorption sampling tube, and the adsorbent filled inside is a two-stage composite of Tenax TA or Tenax TA and Graphitised Carbon Black.

[0053] Then, when collecting the breath components of the process materials in the production of paper-making reconstituted tobacco, place one end of the connecting pipe in the container containing the process materials in the production of the paper-making reconstituted tobacco, and place it above the material, and the other end is connected to the aging One end of the adsorption sampling tube filled with adsorbent, and the other end of the adsorptio...

[0063] 1. Sample pretreatment

[0064] The adsorption sampling tube filled with adsorbent was aged on a TC-20 type aging instrument, under a nitrogen atmosphere with a purity of ≥99.999%, maintaining a nitrogen pressure of 20 psi, and aging at 320°C for 30 minutes. The two ends of the aged adsorption sampling tube are sealed with copper caps for use. The adsorption sampling tube is a filled adsorption sampling tube, and the adsorbent filled inside is Tenax TA.

[0065] Then, one end of the connecting pipe is placed in a container containing the process material (tobacco slurry) in the production of reconstituted tobacco by papermaking, and it is placed above the tobacco slurry, and the other end is connected to the adsorption sampling of the aged filled adsorbent One end of the tube and the other end of the adsorption sampling tube are sealed to the TMP-1500A atmospheric sampler. The TMP-1500A atmospheric sampler pumps the air components around the material into the adsorption sa...

[0076] 1. Sample pretreatment

[0077] The adsorption sampling tube filled with adsorbent was aged on a TC-20 type aging instrument, under a nitrogen atmosphere with a purity of ≥99.999%, maintaining a nitrogen pressure of 20 psi, and aging at 310°C for 30 minutes. The two ends of the aged adsorption sampling tube are sealed with copper caps for use. The adsorption sampling tube is a filled adsorption sampling tube, and the adsorbent filled inside is a two-stage composite of Tenax TA and Graphitised CarbonBlack.

[0078] Then, the aging adsorption sampling tube is placed in a container containing the tobacco stems, which is the raw material of reconstituted tobacco leaves by the papermaking method, and statically adsorbed for 12 hours. After the adsorption is completed, seal both ends of the adsorption sampling tube with a sealed copper cap for use.

Abstract

The invention provides a detection method for the flavor component of papermaking method reconstruction tobacco leaf materials, wherein volatile organic matter components around reconstruction tobacco leaf materials are enriched in an adsorption sampling tube by an atmospheric sampler, and the flavor component volatilized from the materials in the papermaking method reconstruction tobacco leaf finished product and in the production process is determined by using a thermal desorption-gas chromatography-mass spectrometry technology. According to the present invention, the detection has characteristics of simple and easy-performing operation, rapidness, accuracy and the like, can effectively grasp the change rule of the flavor component, especially the odor component, and can provide the important technical support for the cleaning and preserving work of the production line.

Description

Technical field [0001] The invention belongs to the technical field of reconstituted tobacco using a papermaking method, and relates to a method for detecting the odor components of reconstituted tobacco using a papermaking method. Background technique [0002] Papermaking reconstituted tobacco is a tobacco product obtained by using discarded tobacco stems, tobacco dust and some low-grade tobacco leaves during the cigarette production process as the main raw materials, with a small amount of external fiber, and combining pulping and papermaking technology for processing and reorganization. The paper-making process of reconstituted tobacco leaves can not only reduce the production cost of cigarettes, but also improve product quality, and in particular, can significantly reduce the tar content in cigarettes. [0003] At present, the process of reconstituted tobacco by papermaking includes extraction, pulping, papermaking, coating liquid preparation, cutting and packaging, and other p...
