Test result shows; Under the condition of 22 ℃ of relative humidity 45%, temperature; The equilibrium moisture content of above-mentioned monose α-ionol carbonic acid monoester class compound is higher than Ucar 35 contrast pipe tobacco or blank pipe tobacco in various degree; And under the condition of 22 ℃ of relative humidity 85%, temperature; The equilibrium moisture content of above-mentioned monose ester compound is lower than Ucar 35 contrast pipe tobacco or blank pipe tobacco in various degree, shows that disclosed five carbon of the present invention or six carbon monose α-ionol carbonic acid monoester class compound have humectation preferably and moisture-proof role to pipe tobacco.
Embodiment 24: slowly-releasing spices effect test
Tobacco sample to add Ucar 35 is contrast, to above-mentioned five carbon or six carbon monose α-ionol carbonic acid monoester class compound (I~XXV) the slowly-releasing spices effect of pipe tobacco has been carried out the experiment contrast.After above-mentioned monose ester compound solution and propylene glycol solution being sprayed in the pipe tobacco (addition be pipe tobacco weight 0.4%) respectively and placing certain hour, 0.5 gram of taking a sample respectively is that solvent carries out supersound extraction with the methylene dichloride; Dichloromethane solution after the extraction utilizes the content of flavor matter in the gas chromatograph-mass spectrometer analysis filtrating behind filtering with microporous membrane.
Test result shows; The content of typical flavor matter all is higher than the tobacco sample that Ucar 35 was handled in various degree in the tobacco sample that above-mentioned monose ester compound was handled, and shows that disclosed five carbon of the present invention or six carbon monose α-ionol carbonic acid monoester class compound have certain flavour ingredient evaporable effect in the pipe tobacco that slows down.
Embodiment 25: the thermo-cracking composition is analyzed
Adopt online thermal cracking-gas chromatograph-mass spectrometric hyphenated technique, (the thermo-cracking composition of I~XXV) is studied to above-mentioned five carbon or six carbon monose α-ionol carbonic acid monoester class compound.Take by weighing about 0.2mg sample respectively, place solid sampler, under 200 ℃, 450 ℃ and 700 ℃, carry out the moment cracking, the cracking atmosphere is a helium, and split product is directly imported in the Gas Chromatography-mass Spectrometer (GCMS) by helium and carries out qualitative analysis.
Mensuration result shows; These compounds all have aroma component such as α-ionol to produce at 200 ℃, 450 ℃ and 700 ℃, show that disclosed five carbon of the present invention or six carbon monose α-ionol carbonic acid monoester class compound have the effect that thermo-cracking discharges aroma component.
Embodiment 26: the sensory evaluating smoking estimates
For disclosed five carbon of the present invention or six carbon monose α-ionol carbonic acid monoester class compound (I~XXV), carried out sensory evaluating smoking's evaluation with following method.
Aqueous ethanolic solution with 50% is a solvent; Above-claimed cpd and Ucar 35 be mixed with solution and evenly spray in the blank pipe tobacco (addition be pipe tobacco weight 0.4%) respectively; Each tobacco sample behind the application of sample is placed the climatic chamber balance 48h of 22 ℃ of relative humidity 60%, temperature; Process cigarette; Put into balance 48h under the condition of 22 ℃ of relative humidity 60%, temperature again, it is carried out sensory evaluating smoking's evaluation by panel of experts.
Smoking result shows; Compare with Ucar 35 contrast cigarette; The cigarette flavor amount of having added above-mentioned monose ester compound increases, releases fragrant even, good with the fragrant Harmony of cigarette; The aesthetic quality be improved significantly, showing that disclosed five carbon of the present invention or six carbon monose α-ionol carbonic acid monoester class compound have increases perfume quantity, releases the fragrant all even effect that improves the cigarette aesthetic quality.
