Teaching of the Correct Amount of Salt in Miso Soup (2) : The Effectiveness of Salt Meters

Abstract

In the previous report we showed that it is possible to teach children to recognize by taste the amount of salt good for their health. In this paper we investigated the use of a salt meter easy to use for children in the preparation of miso soup and examined it's effectiveness. The results were as follows: 1) Although there was the same recipe, there were differences in the salute densities of the miso soup prepared by sixth grade. 2) An instruction to cook miso soup ran as follows: ・The ratio of miso to water has to be calculated according to the salt density of miso used. ・To be necessary quantity of water a surplus has to be added to compensate for the loss on account of evaporation. ・Ingredients of the soup such as vegetables should not be boiled too long. 3) By the use of salt meters children gained practical knowledge about the correct amount of salt in healthy food.
