Patent ID: 7279187

Claim:
A mineral-fortification system comprising: a) a bottle cap comprising a pouch and a pouch opener, b) a powder contained within the pouch, the powder comprising at least one mineral and a redox modulating compound; and wherein when the cap is secured onto the opening of a bottle containing a liquid and when the pouch opener is activated, the powder is released from the pouch and mixes with the liquid to form a mineral fortified liquid composition that is fortified with the at least one mineral and has a pH between about 2.5 and 9.5, is substantially free of a flavor or sweetener compound, is not significantly different from water in metallic taste or after-taste, and the mineral fortified liquid composition has a redox potential that satisfies the following equation: 0≧ RP− ( A−B*pH ) wherein RB is the measured redox potential in millivolts of the mineral fortified liquid composition, pH is the pH of the mineral fortified liquid composition, A is 400 and B is 20.
