Abstract
A sensory evaluation of the deodorizing efficacy of a titanium oxide type of deodorant was conducted. The percieved difference by the subjects for odors in a refrigerator was assessed by 13 contrasting pairs of adjectives on an 11-point scale. The assessment 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 one week after removing it from the refrigerator. The obtained sensory spectrum corresponding to the changes of scores between the first and the second (second minus first) showed an upward tendency with a positive value in terms of 13 descriptors. This implies an improvement of odors when placing the deodorant in the refrigerator. The respective spectrum (third minus first) at the removal was just the reverse. These results became fixed with the repetition and extension of the experiments in the present study.
