Description
Technical field
The invention belongs to technical field of cigarettes, relate to one type of monose ester cigarette humectant, be specifically related to monose Geraniol carbonic acid di-esters compound, its preparation method and conduct thereof and have the application that the humectation performance has the new cigarette humectant of flavouring and the effect of slowly-releasing spices concurrently.
Background technology
Flavouring humectation and cigarette quality are in close relations." cigarette industry Eleventh Five-Year Plan program for the development of science and technology " and " the medium-term and long-term science and technology development planning outline (2006-2020) of cigarette industry " spells out, and flavouring humectation technical study is one of main direction of industry science and technology coming years research and scientific and technical innovation.
The ideal humectant should have physics humectation and sense organ humectation function concurrently.The physics humectation is promptly preserved moisture, refer to keep pipe tobacco in the course of processing water ratio, improve the anti-processibility of pipe tobacco and keep the water ratio of finished cigarettes; The sense organ humectation then is meant and improves the smoking property of cigarette comfort level, as reducing flue gas drying sense and pungency, improving pleasant impression etc.The humectant that adopts in China's production of cigarettes at present is mainly polyhydroxy substances such as Ucar 35, glycerine, sorbyl alcohol; But it is really not satisfactory that it is kept the finished cigarettes water ratio and improves the effect of sucking comfort level; As hour in relative humidity; There are problems such as moisture in cut tobacco scatters and disappears comparatively fast, main flume moisture is on the low side, pungency is bigger than normal, dry sensation is obvious; And when relative humidity was big, this type of humectant can not stop the taken in excess of moisture, and the too high cigarette of moisture content is prone to macula lutea even goes mouldy.
The ideal sweetener should possess stable in properties, release characteristics such as perfume is even, high safety.The present compound that the sweetener major part is lower as molecular weight, boiling point is low, volatility is stronger that uses of perfuming cigarette exists to be prone in the high temperature process process volatilely between loss, shelf lives release disadvantages such as perfume is inhomogeneous when losing fragrance, suction.
Therefore, research and development have the novel humectant that better humectation performance has flavouring and the effect of slowly-releasing spices concurrently, and humectation performance and the international competitiveness that improves China's cigarette product had important practical significance.
