Embodiment 1

[0055] 1) Sample processing

[0056] According to the national standard (GB2635-92), select 10 complete leaves of the first-cured tobacco leaves of the upper, middle and lower parts of the 2011 Kunming Hongda variety (B2F, C3F, X2F), and remove the stems. figure 1 The method is longitudinal equal-area slitting, and the number below the coordinate axis is the percentage of each slitting point from the leaf tip to the leaf base to the length of the tobacco leaf. The above-mentioned 36 samples were cut into shreds respectively, dried appropriately, pulverized, passed through a 40-mesh sieve, and stored in sealed bags for testing.

[0057] 2) Chemical composition test

[0058] According to the standard test method of the tobacco industry, the total sugar, reducing sugar, nicotine, total nitrogen, ammoniacal alkali, and chlorine content of the above samples were measured by a continuous flow analyzer, and the potassium content of the tobacco leaf sample was determined by flame pho...

Embodiment 2

[0066] 1) Sample pretreatment

[0067] According to the national standard (GB2635-92), select 10 complete leaves of the 2011 Yuxi K326 variety B2F grade first-cured tobacco leaves, remove the stems, and press each half piece figure 1 The method is to cut into 12 segments of equal area in the longitudinal direction, collect the tobacco leaves of the same segment respectively and cut them into shreds, dry them properly, grind them, and pass through a 40-mesh sieve, then put them in sealed bags and store them for testing.

[0068] 2) Near-infrared spectrum collection

[0069] Under the conditions of ambient temperature 25°C and stable relative humidity, a certain amount of tobacco powder samples were packed into sample cups to ensure that the samples were loaded with the same tightness and thickness, and then their near-infrared spectra were measured with a near-infrared spectrometer. The spectral scanning range is 10000-4000cm-1, the number of scanning times is 64, and the reso...

Embodiment 3

[0076] 1) Sample pretreatment

[0077] According to the national standard (GB2635-92), 10 complete leaves of first-cured tobacco leaves of three grades (B2F, C3F, X2F) of the upper, middle and lower parts of the 2011 Kunming Hongda variety were selected; figure 1 The method is longitudinally equal-area slitting. The above-mentioned 36 samples were cut into shreds respectively, dried appropriately, pulverized, passed through a 40-mesh sieve, and stored in sealed bags for testing.

[0078] 2) Chemical composition test

[0079] According to the standard test method of the tobacco industry, the continuous flow analyzer measures the total sugar, reducing sugar, nicotine, total nitrogen, and ammoniacal alkali of the above samples, and uses the flame photometry to measure the potassium content of the tobacco leaf sample. Some of the test results were simply calculated to obtain protein, nicotine nitrogen, total volatile alkali, Shimuke value, nitrogen-alkali ratio, sugar-alkaline r...

Abstract

The invention relates to a tobacco leaf slitting method based on a chemical component distribution rule. After the tobacco leaves are slit, chemical component information of different slit portions is measured, statistic analysis is conducted to the chemical component information of the tobacco leaves and the slit portions, and slit frequency and slit positions of the tobacco leaves are confirmed according to the chemical component distribution rule of the tobacco leaves. Due to the fact that the chemical components of the tobacco leaves are the internal factors which decide quality characteristics and smoking quality of the tobacco leaves, the slit frequency and slit positions of the tobacco leaves are confirmed by the tobacco leaf slitting method from the viewing angle of chemical substance components of the tobacco leaves, and therefore the tobacco leaf slitting method based on the chemical component distribution rule has rationality and scientificity with regard to subdividing and promoting internal usage value of one tobacco leaf. The tobacco leaf slitting method based on the chemical component distribution rule provides novel theoretical foundation of new techniques of sectional type threshing and redrying.

Description

technical field [0001] The invention specifically relates to a method for cutting tobacco leaves based on the distribution rules of chemical components, which belongs to the technical field of cigarette industry. Background technique [0002] A complete tobacco leaf can be divided into several sections such as the tip, the middle of the leaf and the base of the leaf. The appearance quality, physical properties, chemical indicators and sensory quality of different sections in the tobacco leaf are different, so different sections in the tobacco leaf have different use values, then How to subdivide and improve the use value of a tobacco leaf? [0003] At present, some studies have been carried out at home and abroad on how to subdivide and improve the use value of a tobacco leaf. In the field of leaf threshing and rebaking technology, different locations of tobacco leaves have different physical processing properties, chemical characteristics and sensory evaluation effects, an...
