The Rural Development Administration of Korea has developed a new portable sensor that measures the amount of salt in soup, officials announced this week.
It works kind of like those pregnancy test strips. About the size of a thermometer, you dip it into the soup and in about three seconds it displays the concentration of salt. It was able to measure salt concentration within a margin of error of 0.1 percent in tests, according to the Korean RDA.
The device will be tested further at hospitals that are providing low-salt diets for patients with high blood pressure and other conditions. If it tests well, they hope to commercialize the sensor within this year, RDA officials said. The price will be around $1 each (in USD).
Koreans consume an average of 13.4 g of sodium per day, about three times the 5 g limit recommended by the World Health Organization.
There are also millions of Americans who could probably use such a device, too. If it tests well, this little strips could become as popular an import here as the Hyundai.
