The invention provides an artificial saliva used for snuff research and a preparation method thereof, belonging to the technical field of artificial saliva preparation. The artificial saliva of the present invention is prepared from an aqueous solution comprising the following components in mass concentration: NaCl 0.392-0.408 g/L, KCl 0.392-0.408 g/L, CaCl 2 ·2H 2 O 0.7791-0.8109 g/L, NaH 2 PO 4 2H 2 O 0.7644～0.7956g/L, Na 2 S 2H 2 O 0.0049～0.0051g/L, urea 0.98～1.02g/L, carboxymethyl cellulose 2.94～3.06g/L, pH of the artificial saliva The value is 7.0. The artificial saliva of the present invention is similar to the artificial saliva in the detection of nicotine in the mouth; and the artificial saliva has good stability and a certain viscosity; there are few types of formula components, all of which are common compounds, and the cost is low. |
