Problems solved by technology

It would be very difficult to test the contents of all liquid monomers in cigarettes. If one monomer is used as a marker, it is difficult to represent various liquid monomers with different physical and chemical properties. Solvents may not necessarily represent the transfer rate of key liquid components, and it is also difficult to obtain research results that are beneficial to fragrance design

Embodiment 1

[0033] Example 1 Selection of Markers

[0034] Taking a cigarette shredding sample as the object, take 2 equal parts of unadded tobacco slices, 1 part is used as a blank sample, and the other part is added according to the normal feeding amount. The two samples were subjected to solvent extraction and then analyzed by GC / MS instrument. It was found that some volatile and semi-volatile compounds were added to the tobacco flake samples after feeding. Combined with the analysis results of the unfortified samples, four new substances, including PP, EM, MT, and SE, were added to the tobacco sheet after feeding (wherein PP stands for propylene glycol, EM stands for ethyl maltol, MT stands for menthol, and SE stands for medium in the extract. key ethyl ester). After qualitative identification, it is confirmed that it is the characteristic aroma component in the feed liquid, and its component properties are shown in Table 1 below. The properties and attributes of the four substances...

[0037]Example 2: Detection of markers

[0038] (1) Internal standard solution: Accurately weigh 0.2 g of phenethyl propionate, use ethanol as a solvent, dilute to a 100 mL volumetric flask, and shake well to obtain the internal standard stock solution. Accurately pipette 1mL of the internal standard stock solution, use ethanol as a solvent, dilute the volume to a 100mL volumetric flask, and shake well to obtain the internal standard solution.

[0039] (2) Standard working solution: Accurately weigh 10.0g PP, 0.075g MT, 1.0g EM and 0.025g SE, use ethanol as a solvent, dilute to a 100mL volumetric flask, and shake well to obtain a primary standard stock solution. Accurately pipette 1 mL of the primary standard stock solution, use ethanol as a solvent, dilute the volume to a 10 mL volumetric flask, and shake well to obtain the secondary standard stock solution. Accurately pipette 10 μL, 20 μL, 80 μL, 200 μL, 400 μL and 1 mL of the secondary standard stock solution, respectively,...

[0047] Example 3: Calculation of Marker Retention

[0048] After the equipment in the silk making and drying process runs smoothly, 30 samples are randomly selected every 1 min from the exit of the process, and each sample is about 20g. Then, the obtained samples were prepared according to the shredding method, that is, the laboratory shredder was started, and the samples were put into the inlet of the shredder and shredded (the shred width was 0.9-1.0 mm). The cut sample is immediately put into a plastic bag, shaken well, and mixed evenly. This is the sample to be tested. The above series of standard working solutions were analyzed by GC / MS, and the instrument conditions were shown in Example 2. Calculate the retention rate of each marker after the drying process according to the following formula:

[0049] C X = X H ‾ X ...

Abstract

The invention discloses a method for determination of a material liquid retention ratio in cut cigarette tobacco preparation. The method comprises the following steps of A, marker selection, B, marker detection method establishment, C, sample preparation, D, marker detection analysis, E, marker retention ratio calculation and F, material liquid retention ratio calculation. The method selects a specific substance in the material liquid as a marker, realizes quantitative research on transfer change cases of the material liquid in a processing process by a chemical apparatus-based analysis detection means, solves the problems of evaluation based on a single substance and objective impossibility of evaluation based on all material liquid components, provides a complete, objective and scientific evaluation method for material liquid absorption and transfer in the quantitative cut cigarette tobacco-preparation and material-feeding processes, realizes improvement of a feeding device and a processing process, and has a very important meaning for improvement of cigarette product quality and stability.

Description

technical field [0001] The invention belongs to the technical field of cigarette shredding, and in particular relates to a method for measuring the retention rate of feed liquid in the process of cigarette shredding. Background technique [0002] Tobacco feed liquid is an additive added to cut tobacco during cigarette production. It is an additive made up of two or more spices in a certain proportion and adding appropriate auxiliary materials and solvents. It is specially used for flavoring and flavoring various tobacco products, so that it can produce beautiful aroma and comfortable when burning. taste. In the process of processing, according to the requirements of production and formula, a certain amount of material liquid is accurately and evenly applied to the in-process product. Due to the influence of factors such as processing conditions, combustion conditions, raw and auxiliary materials, etc., the absorption and retention of feed liquid will change to a certain ex...
