Description
Technical field
The invention belongs to technical field of tobacco, relate to a class monose ester cigarette humectant, be specifically related to monose β-ionol carbonic acid monoester class compound, its preparation method and conduct thereof and there is the application that humid keeping 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.< < tobacco 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 of < < tobacco industry (2006-2020) > > explicitly point out, and flavouring humectation technical study is one of main direction of industry science and technology coming years research and scientific and technical innovation.
Desirable humectant should have physics humectation and sense organ humectation function concurrently.Physics humectation is moisturizing, refer to maintain pipe tobacco in the course of processing water ratio, improve the resistance to processibility of pipe tobacco and maintain the water ratio of finished cigarettes; Sense organ humectation refers to and improves smoking property of cigarette comfort level, as reduced flue gas drying sense and pungency, improving pleasant impression etc.The humectant adopting in China's production of cigarettes is at present mainly the polyhydroxy substances such as propylene glycol, glycerine, sorbyl alcohol, but it maintains finished cigarettes water ratio and improves that to suck the effect of comfort level really not satisfactory, as in relative humidity hour, there is the 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 is larger, 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 and even goes mouldy.
Desirable sweetener should possess stable in properties, release the features such as perfume is even, high safety.The sweetener major part that at present perfuming cigarette is used is the compound that molecular weight is lower, boiling point is low, volatility is stronger, exists in high temperature process process easily volatilely between loss, shelf lives to release the fragrant disadvantage such as inhomogeneous while losing fragrance, suction.
Therefore, research and development have the novel humectant that better humid keeping performance has flavouring and the effect of slowly-releasing spices concurrently, to improving humid keeping performance and the international competitiveness of China's cigarette product, have important practical significance.
