Abstract
An oxygen scavenger is provided. An oxygen scavenger comprises iron, malic acid, and a wicking agent. A method for scavenging oxygen from an enclosed container comprises providing an oxygen scavenger compound comprising iron, malic acid, and a wicking agent, sealing the composition in an oxygen permeable, water impermeable container, and activating the composition by injecting water into the container.
Claims20
An oxygen scavenging composition on a dry basis consisting essentially of iron, malic acid, and a wicking agent.
A method of removing oxygen from an enclosed container without producing gas comprising:
- providing an oxygen scavenging composition comprising iron, malic acid, and a wicking agent;
- sealing the oxygen scavenging composition in an oxygen permeable, water impermeable container;
- and activating the oxygen scavenging composition by injecting a solution containing water into the oxygen permeable, water impermeable container containing the oxygen scavenging composition, wherein substantially no gas is produced.
An oxygen scavenging composition on a dry basis consisting essentially of iron, malic acid, a wicking agent, and a salt, wherein the salt does not substantially affect the pH of the composition.
