The invention concerns a production process of a zinc enriched drinking water, also called final water product, which, starting from a water matrix comprising drinking water, comprises, a first step of: Measuring the pH of the water matrix (step A), and then, in one order or the other, the steps of: Acidifying the water matrix (step B) in order to get a final water product having a pH lower than 7, and Adding zinc (step C) in a concentration comprised between 0.8 mg/l et 5 mg/l, so that sedimentation of zinc in the final water product is lower than 10% of soluble zinc over a period of 12 months at a maximum temperature of 40° C. The invention also concerns a zinc enriched drinking water composition and packaged zinc enriched drinking water.

1. A method for producing a zinc enriched drinking water which, starting from a water matrix comprising drinking water, the method comprising: measuring the pH of the water matrix,and then;acidifying the water matrix in order to get a final water product having a pH between 6.5 and 7; andadding zinc
1. A method for producing a zinc enriched drinking water which, starting from a water matrix comprising drinking water, the method comprising: measuring the pH of the water matrix,and then;acidifying the water matrix in order to get a final water product having a pH between 6.5 and 7; andadding zinc in a concentration comprised between 0.8 mg/l and 5 mg/l,so that sedimentation of zinc in the final water product is less than 10% of soluble zinc over a period of 12 months at a maximum temperature of 40° C. 2. The method according to claim 1, wherein the water matrix comprises partially or totally demineralized drinking water. 3. The method according to claim 1, in which the step of acidifying the water matrix is made by adding a strong acid to the water matrix. 4. The method according to claim 3, in which the strong acid is selected from the group consisting of sulfuric acid, phosphoric acid and hydrochloric acid. 5. The method according to claim 1, wherein zinc is added in the form of a zinc salt. 6. The method according to claim 1, comprising adding magnesium and/or calcium. 7. The method according to claim 1, wherein magnesium is added at the same time as zinc during zinc adding step. 8. The method according to claim 1, wherein magnesium is added as magnesium sulfate or magnesium chloride in a concentration between 10 mg/l and 375 mg/l. 9. The method according to claim 1, wherein calcium is added as calcium chloride in a concentration between 20 mg/l and 1 g/l. 10. The method according to claim 1, comprising adding bicarbonates, as sodium bicarbonates and/or potassium bicarbonates. 11. The method according to claim 1, comprising a step of verifying the final water product pH. 12. The method according to claim 1, comprising a step of ozonation of the final water product before its packaging.
