Sensory characteristics of 2-heptanone. Part I. Threshold values, concentration/odour intensity relations, methodological aspects.
The evaluation of threshold values and concentration/odour intensity relations for 2-heptanone has been carried out in two laboratories applying strictly uniform materials, methods and laboratory procedures. The results obtained in aqueous and oil medium are discussed taking into consideration the influence of methods and judges as variability factors. It has been concluded that standardization of the methods and detailed laboratory procedure seem to be critical factors for inter-reproducibility of the results in various sensory laboratories.
