[Zhang2013] Zhang, G., S. Nan Gao, W. Ding Wei, and Q. Jian Xu, "Proton Transfer Reaction-Mass Spectrometry Determination of the Emission Rate of Flavor Ingredients in Toothpastes", Applied Mechanics and Materials, vol. 299: Trans Tech Publ, pp. 229–232, 2013.
Under the experimental conditions, the headspace concentration of two flavor ingredients in toothpastes, limonene (C10H16) and menthone (C10H18O), was measured with proton transfer reaction - mass spectrometry (PTR-MS). Combined with the theoretical diffusion model and analytical solution, the partition coefficient and the emission rate of the two ingredients from toothpaste diluent to the circulated air were calculated. Theoretical Solutions of the distribution coefficients were obtained respectively as 0.00432 and 0.00418 for C10H16 and C10H18O. The corresponding simulated flavor concentration in headspace air Ca(t) had good agreement with the experimental values (R2 = 0.983 and 0.958 respectively). The exponential decay rate formulas for the two flavors were obtained from experimental data and the solution of the theoretical model.
