As whale meat loses its freshness, it begins to emit a bad smell and becomes unfit for food. In order to reduce the bad smell, it is necessary to make use of seasonings. Here we study the effect of the three kinds of seasonings; ginger and garlic, onion and bay-leaf, and sesame. At 5% significance level, we can conclude that the effect of onion and bay-leaf is somewhat lower than the effect of the other two kinds of seasonings. It is found that old people have a tendency to like the flavour of sesame. Further a measurement of preference is carried out to see how the wink meat is eaten and the result is analyzed statistically.
