COMPARISON BETWEEN RESIDENTS AND PANEL ON SENSORY EVALUATION OF STATIONARY ODOR

The purposes of this study are to confirm the lowest level of odor in the living-dining rooms with kitchen (LDKs) and to examine the difference between residents and panel on the odor evaluations. Odor samples for olfactory measurements were collected in LDKs of 40 by residents. We measured odor concentration of odor samples by the triangle odor bag method. In addition odor intensity, odor hedonics, and odor quality of odor samples were evaluated by panel and residents. The odor concentration showed 10 - 1700 and the average was 70. The measurement values of 9 LDKs were higher than the outdoor regulation standard. On the 6-step odor intensity, the average of panel was 3.2 and the average of residents was 0.4. On the 9-step odor hedonics, the average of panel was -1.4 and the average of residents was 1.6. The difference between residents and panel for the intensity and the odor hedonics was about 3 steps.
