Problems solved by technology

However, in the design of low-carbon monoxide cigarette products, in order to keep the sensory quality of cigarettes unaffected, it is necessary to use functional materials with low carbon monoxide emissions and slightly higher tar emissions (because some flavor substances exist in cigarette tar). Unconventional treatment of cut stems is desired to reduce the organoleptic quality, but the existing cut tobacco stem products cannot meet this requirement

Embodiment 1

[0031]Add 10 kg of hot water at 60°C to a certain container, then add 0.4 kg of L-cysteine, and stir until it is completely dissolved; add 2 kg of tobacco stems into the container, dip it so that the water content reaches 33.2%, and then place it for 2 hours; use a conventional stem cutter to cut the tobacco stems, the thickness of the cut stems is 0.5 mm; shred the stem slices with a shredder, and the shred width is 1.1 mm; dry the modified cut stems obtained, and observe the modified cut stems color, and then place the modified shredded stem in an environment with a temperature of (22±1)° C. and a relative humidity of (60±3)% for 48 hours and set aside. The modified shredded stem prepared by the above method is added into the shredded tobacco according to the proportion of 10%, and then cigarettes are rolled according to the conventional production method. The tar release amount and carbon monoxide release amount of cigarettes were measured, and the sensory quality was evalu...

Abstract

The invention discloses a method for preparing modified tobacco stem shreds and application. Tobacco stem is placed in L-cysteine aqueous solution at 45-80 DEG C to undergo soaking treatment and then cut into shreds, and the modified tobacco stem shreds are obtained. The prepared modified tobacco stem shreds are good in color and good in tobacco shred matching performance. Compared with a conventional tobacco stem product, the release amount of carbon monoxide can be lowered after the modified tobacco stem shreds are added into cigarettes, and the influence on cigarette tar release amount is small.

Description

technical field [0001] The invention relates to a preparation method and application of modified shredded tobacco stems, in particular to a method for modifying and shredding tobacco stems, and adding modified shredded tobacco stems to cigarette shredded tobacco formula for reducing carbon monoxide, belonging to the field of cigarette preparation . Background technique [0002] The veins in tobacco leaves are commonly known as tobacco stems. At present, there are many forms of utilization of tobacco stems, and the most widely used ones are expanded cut stems and shredded tobacco stems. What is customarily called expanded stalks refers to expanded cut stalks, which adopts a process of cutting stalks into slices at one time, and the thickness of the slices is generally about 0.18mm; the shredded tobacco stems generally use the shredded process of pressing the stems and then cutting them. First, the round tobacco stems are pressed into sheets, and then the sheet-shaped tobacco...
