Description

Gold thread belt particles for increasing characteristic sweet feeling of cigarette smoke and preparation method and application thereof
Technical Field
The invention belongs to the technical field of cigarette flavoring in the tobacco industry, and particularly relates to a gold thread belt particle for increasing characteristic sweet feeling of cigarette smoke, a preparation method and application thereof.
Background
Currently, with the continuous enhancement of health consciousness of cigarette consumers, low-tar and low-harm products such as medium-count, fine-count and heating non-burning cigarettes are gradually favored by partial consumers. However, the harm and tar reduction is accompanied by the loss of the aroma of the cigarettes and the deterioration of the comfort level, while the cigarette flavoring can set off, supplement the aroma of the cigarettes, increase the smoke concentration, improve the taste, remove and cover the miscellaneous gases, reduce the irritation, and also can give the products graceful characteristic aroma, highlight the personalized style of the cigarette products, and the cigarette flavoring technology has become one of the most critical technologies for keeping the aroma of the cigarettes in the harm and tar reduction work.
The cigarette flavoring mode mainly comprises tobacco shred flavoring and auxiliary material flavoring (including filter tip, cigarette paper, etc.). Compared with tobacco shred flavoring, the filter tip flavoring technology has the following advantages: firstly, the loss and pyrolysis of spice in the storage and burning process of cigarettes can be avoided; secondly, the loss of spice during the static burning period of the cigarettes can be avoided; thirdly, the interception of the tobacco shred, the filter tip and the like to the perfume can be reduced, and the transfer efficiency is increased; fourth, can adopt multiple perfuming methods, meet the controllability requirement of different spices storage and release. The flavor attributes of the middle count, the fine count and the heated non-combustible cigarette products are improved by adopting a filter tip flavoring means, so that the sensory quality of the cigarette products is ensured while harm and tar are reduced, and the requirements of sustainable development of the tobacco industry are met.
The natural plant material contains rich organic compounds, has the functions of flavoring, sterilizing, resisting oxidation and the like, and can achieve the effects of flavoring, preserving moisture and improving the quality of cigarettes when being applied to cigarettes. The natural plant material is applied to the cigarette filter tip, and has the advantages of no participation in combustion, no generation of other toxic and harmful substances and the like; the natural plant material is added into the cigarette filter tip, so that the smoking quality of the cigarette can be improved while the smoke fragrance is improved.
The golden ribbon is also called golden waistband, is a filament of golden ribbon of Usneaceae, usneales, ascomycetes, and is a common Chinese herbal medicine for people in Shaanxi province, and is commonly used for treating soreness of waist and leg pain. The golden silk ribbon is mainly distributed on the trees in pine forest or on dead wood with the elevation of mountain and north slope of Qinling mountain of about 3000 m. In recent years, with the development of special plants of Taibai mountain in Shaanxi and the demand of people for health care, gold ribbons of one of the three treasures of Taibai have been attracting attention. The golden silk ribbon is rich in chemical components such as dark tea stain, kanali, phospho-coating acid, trichromatic acid, speckle-reducing coating acid, etc. At present, the application of Shaanxi characteristic plant gold bands in flavoring of filters is not reported, but the addition of gold band particles to increase the sensory quality of cigarettes has good application prospect and advantage, so that it is necessary to provide gold band particles and a preparation method thereof.
