. The relationship between the physical carbonation level of carbonated spring water and the magnitude of carbonation perception was determined by a trained panel using two assessing conditions, swallowing and expectoration. Spring water was carbonated to 5 carbonation levels. Panelists were asked to rate their perception of carbonation intensity by using magnitude estimation. The power function equations were established with high correlation coefficients for both assessing conditions. The exponents, 2.79 (swallowing) and 2.65 (expectoration), suggested a sharp increase of perceived CO 2 magnitude with increasing concentration. There was no significant difference between exponents resulting from the two assessing conditions. Therefore, the response should not be affected if samples are expectorated in studies of carbonation perception.
