Abstract: A mineral-fortification system that has a bottle cap, a pouch and a pouch opener. A powder is contained within the pouch, and the powder contains at least one mineral and a redox modulating compound. 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 at least one mineral and has a pH between about 2.5 and 9.5.

Abstract: A packaging system useful for roast and ground coffee, having a container with a closed bottom, an open top, and a body enclosing a perimeter between the bottom and the top. An annular protuberance is disposed upon the body and is continuously disposed around the perimeter of the body proximate to the top. The protuberance forms a surface external to the body. The surface is substantially perpendicular to the longitudinal axis of the container. A flexible closure is removeably attached and sealed to the protuberance so that the closure seals the interior volume of the container.
