註釋The Phase Ratio Variation (PRV) method is a very valuable method commonly used for liquid/vapor partition coefficients data acquisition of aroma compounds. Nevertheless, there are some limitations to this method, especially for volatile compounds. A careful examination of the PRV equation leads us to propose the following expression: We performed an examination for two cases of K values (K1=0.001 and K2=0.05), highlighting that a careful choice of β range values is crucial in the reliability of the regression calculation 1/A versus β.
