Technical field
The present invention relates to tobacco additive agent field, the specifically preparation method of a kind of natural baccy moist-keeping flavouring agent and the application in cigarette thereof, this moist-keeping flavouring agent is together with cigarette feed liquid or add separately in tobacco leaf, can improve the retention ability of tobacco, increases pliability and the resist processing of tobacco, smoker is made not have dry sensation, there is soft flue gas, dispel assorted gas, reduce excitant, improve and inhale taste, improve the effect of flue gas aroma quality.
Background technology
Production of cigarettes is a complicated process, and operation is various, advanced technology, and quality requirement is strict.The fine quality of cigarette mainly comes from the raw tobacco material used in formula, and to the processing and treating method of tobacco leaf in production of cigarettes process, and each manufacturing procedure also plays an important role.Even formula, excellent tobacco leaf preferably, also may deal with improperly because of processing or manufacture in a rough and slipshod way and scrap; Otherwise poor tobacco leaf, through meticulously suitable processing, also can make up the deficiency of its some aspect and produce good product.So scientific and rational processing technology is the guarantee of cigarette quality.In production of cigarettes process, in order to increase pliability and the resist processing of tobacco, in order to improve and improve the smoking quality of cigarette, also reinforced and perfuming process to be carried out to tobacco leaf, offal and pipe tobacco.The additive of cigarette charging is just feed liquid.Except comprising in cigarette feed liquid: except cocoa power and/or its extract, licorice powder and/or its extract, corn syrup, high-fructose corn syrup, sucrose, invert sugar, honey, molasses, dried prune concentrate, fig concentrate and raisins concentrate, also add a certain amount of humectant.The most frequently used application cigarette humectant is the earliest glycerine, propane diols, secondly also has sorbierite, diethylene glycol (DEG) and triethylene glycol etc.Wherein, what humectation ability was the strongest is glycerine and propane diols, and the two usually with the use of.Glycerine and propane diols are polyalcohols because of it, stronger water imbibition and have good cigarette humid keeping performance.But, just because of glycerine, propane diols, there is stronger water imbibition, and make the impact of the moisture content of the cigarette shreds adding glycerine and propane diols usually by ambient humidity very large.Ambient humidity is low, and the moisture content of cigarette shreds is low, and the mildness of cigarette smoke is deteriorated; Ambient humidity is large, and the moisture content of cigarette shreds is high, and cigarette shreds may go mouldy, especially at south China plum rain season.Therefore, in order to find better humectant, tobacco business just starts the developmental research of the moist-keeping agent for tobacco reducing the consumption of glycerine cigarette or alternative glycerine from the eighties in 20th century, so far developed multiple tobacco humectant, such as modified starch, KSAP-T(konjaku glucomannan and acrylic acid a kind of graft copolymer), CPL-NR(natural polysaccharide), lactic acid and lactate, citric acid, malic acid, lactic acid and Fe III, Mn II, Zn II, the complex of Ce III, pomace and orange skin water soluble pectin extract etc.Although the humid keeping performance of these humectants some be better than tobacco humectant propane diols, glycerine and the sorbierite etc. commonly used, but it adds to when burning in pipe tobacco may bring adverse influence to cigarette smoke, for example the water soluble pectin extract etc. of modified starch, KSAP-T, CPL-NR and pomace, orange skin all belongs to natural polysaccharide, add the releasing content of coke tar that not only can increase flue gas in cigarette shreds, but also the excitant of flue gas can be made to increase, inhale taste and be deteriorated; The complex of citric acid, malic acid, lactic acid and Fe III, Mn II, Zn II, Ce III may bring Fe III, Mn II, Zn II, Ce III to cigarette smoke.Therefore, development of new tobacco humectant remains one of heat subject of tobacco business research so far.
