Abstract

A study was made to develop a sensory evaluation method to determine the deodorizing efficacy of a titanium oxide type (photocatalytic) deodorizer. In our previous study, after placing the deodorizer in the participant's personal refrigerator, the perceptional changes of the participant for odors in the refrigerator were assessed by 13 contrasting pairs of adjectives on an 11-point scale and an assessment by inquiry was conducted three times; first immediately before placing the deodorant in the refrigerator, then after keeping it in the refrigerator for one week, and lastly at one week after its removal. It was observed that the sensory evaluation spectrum corresponding to the scores of the second inquiry minus the first inquiry resulted in an upward tendency with a positive value of the descriptors, implying an improvement of odors after placing the deodorant in the refrigerator. Here, the sensory evaluation spectrum was represented by a bar graph, in which the mean of the foregoing impression difference was plotted against the descriptors. The objective in this study was to examine whether or not this procedure could be applied to a wide range of functions of manufactured goods of titanium oxide, such as photocatalytic sterilization of bacteria, disinfection of molds, oxidative cleavage of organic compounds, decomposition of odorous molecules and removal of bio-aerosols from the air environment. From the viewpoint of consumers and their daily use, the semantic responses by the subjects to the efficacy of a photocatalytic deodorizer after placing it in the car are reported here in terms of a sensory evaluation spectrum.
