| Outline of Final Research Achievements |
Reducing dietary salt intake without sacrificing the flavor of food or quality of life of patients requiring a reduction in salt intake is an important topic for research. Our study determined the usefulness of the saltiness enhancement action by additives that allow saltiness to be strongly tasted, despite reduction in the amount of dietary salt, and a taste sensor-based taste analysis revealed that γ-aminobutyric acid (GABA)-rich Gabaron tea and broccoli sprouts induced a strong sensation of saltiness. Human sensory assessments also revealed a similar strong sensation of saltiness, comparable to that by 0.9% salt water. The addition of GABA-rich substances to saltwater augments the saltiness, thus suggesting the possibility of reducing dietary salt intake without compromising on the flavor.
