Toshihide Nishimura, chairperson of UIC (left), gave examples of umami rich foods and explained what koku is. He explained what umami substances do to koku.

In his lecture titled “Now You can be a Food Reporter ! - The Scientifically Correct Usage of Tastiness Expressions,” Dr. Nishimura introduced some of the incorrect expressions used in daily life regarding deliciousness, such as “umami and tastiness,” “taste and flavor,” and “koku and tastiness” and explained the differences between them in a scientific and easy-to-understand manner. 

The word “umami” is often confused in Japanese, as it is a homonym in Japanese, having two meanings: “umami” for basic taste and “tastiness” for deliciousness. He also defined and explained the science behind the “koku” of foods.

About 220 people attended the lecture, including readers, authors and publisher’s staff, dietitians, and people in the food industry. They listened intently to Dr. Nishimura, who has been studying the taste of food for nearly 50 years.
After the lecture, participants smiled and said, “I could understand it very well.
