Abstract: | This study is part of an effort to improve the quality of dried shiitake mushrooms (Lentinula edodes) in accordance with consumer preference. Results are presented of a trend survey that examined the preferences of consumers
using questionnaires combined with sensory evaluation. From the original preference (OP) survey, the distributions of OP divided
by age class (AC) were statistically equal to the results obtained in 2000. The medians of OP for teenagers and twenties were
“neutral” and “slightly like,” respectively. A firm preference change occurred between teenagers and those in their twenties.
It is empirically realized that sensory intensity (SI) scores that were too high or too low led to a low hedonic preference
(HP) score. The same tendency was seen for “neutralists” and “likers.” In addition, almost all distributions concerned with
HP had no significant difference between 2000 and 2005; for example, that of SI divided by AC. These results showed that the
preference for dried shiitake mushroom has been unaffected by the passage of the past 5 years. Dried shiitake mushrooms have
been used from ancient times and for many dishes; therefore, the overall preference appears to have remained unchanged. |
