PURPOSE:To obtain drinking water in which adaptability to drinking can be judged at a glance, capable of making an alkali constitution, by adding a specific tree to drinkable water, heating it until it is colored in red. CONSTITUTION:Ground woody part of a tree such as KAYUMERA, etc. grown in alkaline soil or the chips 4 of it are added (1) to the tank 2 charged with the drinkable water 3, they are heated until red sap is extracted from the tree 4 and water is colored in red, to give the alkali drinking water 6 having >=7pH. The drinking water 6 is cooled, packed (9) into the bottle or can 8. When the water colored in red is made acidic by decomposition, etc., it is colored in amber, and its inadaptability as drinking water can be judged at a glance. |
