The detection of cigarette component content, it is as a result similar with the result of true saliva.
Below with reference to embodiment to artificial saliva studied provided by the present invention for buccal cigarette and preparation method thereof and its
Using being described in detail, but they cannot be interpreted as limiting the scope of the present invention.
Embodiment 1
A kind of artificial saliva for buccal cigarette research, the artificial saliva is by including the water-soluble of following mass concentration component
Liquid is prepared: NaCl 0.4g/L, KCl 0.4g/L, CaCl2·2H2O 0.795g/L, NaH2PO4·2H2O 0.78g/L,
Na2S·2H2O 0.005g/L, urea 1g/L, carboxymethyl cellulose 3g/L；Water used in the aqueous solution is deionized water, the people
The pH value of work saliva is 7.0；It is named as the artificial saliva containing carboxymethyl cellulose.
Comparative example 1
Prepare ISO/TR10271 inorganic salt type artificial saliva: NaCl 0.4g/L, KCl 0.4g/L, CaCl2·2H2O
0.795g/L, NaH2PO4·2H2O 0.78g/L, Na2S·2H2O 0.005g/L, Urea 1g/L.
Comparative example 2
Prepare artificial saliva containing enzyme: NaCl 0.4g/L, KCl 0.4g/L, NaH2PO4·H2O 0.69g/L, Na2S·9H2O
0.005g/L, CaCl2·2H2O 0.795g/L, KSCN 0.3g/L, Urea 1.0g/L, amylase 59mg/L.
Comparative example 3
The saliva for collecting 5 aspirations, is stored in 4 DEG C of refrigerators.
By commercially available gold deer board buccal cigarette (black tea taste) 0.35g be respectively placed in artificial saliva of the 6mL containing carboxymethyl cellulose,
In ISO/TR10271 inorganic salt type artificial saliva, artificial saliva containing enzyme and true saliva, 37 DEG C, 30min is stood, is measured above-mentioned
In four kinds of salivas in the amount of dissolution of nicotine and residue nicotine surplus；The dissolution rate of nicotine is calculated according to formula (1),
The results are shown in Table 1.
Dissolution rate of 1 nicotine of table in different type saliva
Note: capitalization A represents the conspicuousness under 0.01 level of signifiance, and lowercase a, b are represented under 0.05 level of signifiance
Conspicuousness；A, a and b is obtained after being calculated by statistics software SAS.
As can be seen from Table 1: the amount of dissolution of the nicotine in true saliva only with the artificial saliva containing carboxymethyl cellulose without
Significant difference.Therefore, the artificial saliva containing carboxymethyl cellulose can more replace true saliva in contrast.Although inorganic salt type
Artificial saliva and artificial saliva containing enzyme and the artificial saliva containing carboxymethyl cellulose do not have a significant difference, but the two is and really
Saliva has significant difference, and the higher cost of artificial saliva containing enzyme, and not easy to maintain.Therefore, the artificial saliva of carboxymethyl cellulose
Liquid has more advantage.
Comparative example 4
On the basis of ISO/TR10271 inorganic salt type artificial saliva, different amounts of carboxymethyl cellulose and starch are added
Enzyme, and different pH is set, prepare 1~No. 9 artificial saliva of number；The component content and pH of specific artificial saliva are as shown in table 2.
The component content and pH situation of 2 number of table, 1~9 artificial saliva
By Mouthsimulator device, the artificial saliva that above-mentioned number is 1~9 is injected separately into golden deer board black tea taste and is sucked
Cigarette collects dissolution fluid in different time periods, studies the variation with the time, the changes of contents of nicotine in dissolution fluid, to study mouth
Release rule containing nicotine in cigarette；And with true saliva to refer to, shown in result figure 1.As can be seen from Figure 1: buccal cigarette nicotine
Release rule trend in the artificial saliva of different formulations is roughly the same, but immediate for this with true saliva (curve 10)
Artificial saliva (curve 8) involved in inventing.
Artificial saliva provided by the invention is accurate to the testing result of buccal cigarette nicotine, most similar with true saliva result,
It can be used in the quality evaluation of buccal cigarette；Meanwhile the artificial saliva stabilization is good, and has certain viscosity, formula components kind
Class is less, and is common compounds, and cost is relatively low.Embodiment statistics indicate that: the amount of dissolution of the nicotine in true saliva with
There was no significant difference for the artificial saliva that the present invention prepares；And release rule of the buccal cigarette nicotine in artificial saliva of the invention with
True saliva is closest.The above is only a preferred embodiment of the present invention, it is noted that for the general of the art
For logical technical staff, various improvements and modifications may be made without departing from the principle of the present invention, these improve and
Retouching also should be regarded as protection scope of the present invention.
