Description
Technical field:
The present invention relates to the tobacco humectant of a kind of molecular weight gradient distribution.
Background technology:
The moisture of tobacco is the important correlative factor of cigarette quality, and when moisture in cut tobacco content is too low, the excitant of cigarette increases, and xerostomia sense is obvious, and impacting throat increases, and tobacco aroma reduces, and oral cavity is residual to be increased, and the quality of tobacco declines to some extent.When tobacco moisture is too high, feed liquid easily penetrates into cigarette paper surface, and cigarette generation look becomes, goes mouldy, and fragrance also can be caused stuffy, and the property sent out declines thoroughly, the defect that suction quality declines.Therefore cigarette humectant can play moisturizing and moistureproof two functions, and the raising for cigarette quality has important facilitation.
Research shows, tobacco is through processing technologys such as just roasting, redryings, and its surface and section are complicated many hollow structures, and this many hollow structures are that tobacco moisture absorbs and lost key factor.And pipe tobacco loose structure is different from poromerics, it is with obvious scrambling, and be the mixed style of micropore, mesoporous and macropore, therefore the selection of humectant must meet the requirement in different space.Humectant molecular weight is too little, will be difficult at pipe tobacco surface filming, and humectant molecular weight is too large, being difficult to infiltrate in the micropore of pipe tobacco, all can affecting the humectation effect of humectant by making humectant.The humectant of conventional tobacco humectant normally Small molecular humectant or starch based modification, these humectants can only meet pipe tobacco humectation demand to a certain extent.
Be different from moisture absorption effect of Small molecular humectant, polysaccharide macro-molecular humectant has the effect absorbing moisture in dry environments equally, in addition, the while that the performance of polysaccharide macro-molecular humectant being hydrophilic, its strand also shows hydrophobicity, and this amphipathic polysaccharide macro-molecular that will be conducive at tobacco surface filming, and completely cuts off the contact of pipe tobacco and environment to a certain extent, reduce rate of water migration, reach humectation effect.
Summary of the invention:
For overcoming the defect of prior art, the object of the present invention is to provide the tobacco humectant that a kind of molecular weight gradient distributes, it includes the tobacco humectant monomer of small-molecular-weight, intermediate molecular weight and the HMW equimolecular quantity order of magnitude, leaching is moistened mutually in the surface of the good gap structure different from tobacco of energy, thus prevent the immersion of the lost of moisture in cut tobacco and humid air, realize humectation effect.
Technical solution problem of the present invention adopts following technical scheme:
A tobacco humectant for molecular weight gradient distribution, humectant raw material, according to the distribution of molecular size range gradient, by weight percentage, is made up of following component:
Humectant raw material, according to the distribution of molecular size range gradient, by weight percentage, is made up of following component:
Described Small molecular humectant be molecular weight ranges 1001000 polyol, described polyol is one or more in propane diols, glycerine, sorbierite, xylitol, glucose, fructose; Described intermediate molecular weight humectant be molecular weight ranges 1000 ~ 100000 polysaccharide compound, described polysaccharide compound is one or more in oligomerization starch, glucan, witloof polysaccharide, LBP-X, Siberian solomonseal rhizome polysaccharide; Described HMW humectant is that molecular weight ranges is 10
5~ 10
6polysaccharide, biogum compounds, described polysaccharide, biogum compounds are one or more in alginate, guar gum, carob, Arabic gum.
According to molecular weight order from high to low, component each in humectant is dissolved in water successively, forms homogeneous phase solution, obtain the tobacco humectant configured.
By the tobacco humectant configured according to 1% ~ 50% ratio adds cigarette charging feed liquid to, expanded cut tobacco feeds in raw material feed liquid, stem feeds in raw material feed liquid or in paper process thin slice coating fluid, and be applied in cigarette in reinforced mode, make it play effect of humectant.
Tobacco humectant prepared by the present invention well can prevent scattering and disappearing of moisture in cut tobacco in dry environments, keep the moisture of pipe tobacco, in wet condition, the moisture absorption of cigarette can be reduced, prevent cigarette from making moist, reduce moisture in cut tobacco rate of change, make pipe tobacco within the longer time, be in suitable moisture scope.Add the cigarette after humectant, xerostomia sense declines, and excitant declines, and pleasant impression makes moderate progress.
Compared with the prior art, beneficial effect of the present invention is embodied in:
First, containing the humectant monomer of different molecular weight in humectant, the compound of these different molecular weights can better moisten with the tobacco surface void of different size and soaks, effect of performance humectant; Secondly, the HMW humectant contained in humectant can help humectant molecule at tobacco surface filming, thus reduces tobacco by surface interface moisture loss or immersion; Therefore, humectant of the present invention all can play good humectation effect in dry environments with under wet environment; Finally, humectant monomer of the present invention is common safety without dangerous compounds, and Long-Time Service is at food, tobacco and cosmetic field, and part of compounds is directly present in tobacco, and these monomers are common is easy to get, and easily promotes.
Below by way of detailed description of the invention, the invention will be further described.
Detailed description of the invention:
Embodiment: the tobacco humectant of the present embodiment molecular weight gradient distribution, its formula by weight percentage, comprise following material: molecular weight ranges 100 ~ 1000 propane diols 20wt%, glycerine 10%, the glucan 0.2wt% of molecular weight 50000D, molecular weight ranges is 10
5~ 10
6guar gum 0.01wt%, surplus is that water accounts for 69.79wt%.
Guar gum, glucan are dissolved in water successively, then add propane diols and the glycerine of respective amount, stirring and dissolving, obtain humectant BR-01.
By BR-01 with 50% ratio add in cigarette feed liquid, add in cigarette according to reinforced mode, make cigarette sample.With add normal feed liquid and the cigarette product adding respective amount propane diols and glycerine carries out comparing under different condition, result is as shown in table 1.Dry environment is 30% humidity, under 22 DEG C of environment, uncoveredly deposits 72h; Wet environment is 80% humidity, at 22 DEG C, uncoveredly deposits 72h.
Table 1. adds BR-01 and compares with the cigarette quality of adding Small molecular humectant
Can obtain from table 1, after adding BR-01, moisturizing and moistureproof effect can be played in cigarette.The organoleptic quality of its product also increases.
Embodiment 2:
