Definitions

  • the invention relates to a mineral water composition, more particularly to a mineral water composition which is palatable.
  • Water is very important for life. It is well known that water makes up about 60% of the body weight in men and 55% of weight in women. It is important to drink at 2 to 3 litres of water in a day. However, most people working in air-conditioned environments find it difficult to consume the adequate quantity of water due to decrease in thirst. A way to drink more water could be to make it more palatable. It will also be of great advantage if the palatability comes with a benefit.
  • EP2565165 is directed to a process for remineralization of water comprising the steps of providing feed water, providing an aqueous solution of calcium carbonate comprises dissolved calcium carbonate and reaction species thereof, and combining the feed water and the aqueous calcium carbonate solution.
  • the document involves mixing CaCCh with RO water that was pre-dosed with carbon dioxide (CO2).
  • the drinking water is mineral enriched as well as palatable to the consumer.
  • the present invention provides a mineral water composition which is palatable and in fact very good tasting.
  • First aspect of the present invention provides a mineral water composition having a pH value of 7.0 to 9.5, the composition comprising, a. 0.0002 to 0.01 wt% of calcium ions

Even when they were mixed in the solid state and when added in water they precipitated out as magnesium and calcium salts. While they are mixed in the solution format also they precipitate out. Some mineral salts have low solubility in water and some desirable mineral salts are not available in stable solid or liquid state.
