Abstract: A humidity control system including: a two-way humidity control material; a substantially pure plant extract blended with the two-way humidity control material to form a mixture; and a package housing the two-way humidity control material and the substantially pure plant extract, wherein the substantially pure plant extract is between about 0.025% and about 5.0% by weight of the mixture.

Abstract: A humidity control system includes a cap including a retention element at an inner surface of the cap, the inner surface of the cap defining an interior volume of the cap, and a package in the interior volume of the cap, the package including a humidity control substance configured to control humidity and a retainer including a sealing interface to enclose the humidity control substance, the retainer being configured to engage the retention element. The package and the inner surface of the cap define a shielded volume.

Abstract: A humidity control system includes a two-way humidity control material, a plant extract, and a package housing the two-way humidity control material and the plant extract. A method of flavoring a product and controlling the humidity of an environment in a container includes inserting a humidity control system in the container and enclosing the product in the container. The humidity control system includes a two-way humidity control material, a plant extract, and a package housing the two-way humidity control material and the plant extract.

Abstract: A container including a tray, an oxygen absorber, and a removable film. The tray includes a base, at least one sidewall extending in a first direction from the base, and at least one partition extending in the first direction from the base. The partition divides an interior of the tray into at least a first compartment and a second compartment adjacent to the first compartment. The container also includes at least one aperture in the at least partition. The aperture places the first compartment in fluid communication with the second compartment. The oxygen absorber is in the first compartment or the second compartment, and the removable film covers the first compartment and the second compartment.
