| Outline of Final Research Achievements |
Hypertension has the largest number of patient in life style related disease and its cause originates from the excess of salt intake. Therefore, the reduction of salt intake is important for the prevention of hypertension. However, only reducrion of salt causes the problem of dreary taste. We tried the technological development which can enhance saltiness and acquire delicious satiness even the reduction of salt as a method able to dissolve this problem. Namely,we injected human gene of receptor for saltiness into Xenopus oocytes and expressed the corresponding protein and used this as a sensor for the screening of substances enhancing saltiness from agricultural stuffs, fermenting foods, food components. As a result, we succeeded in finding one substance enhancing saltiness from a kind of agricultural stuff.
