<p>An atmosphere control device comprises a container 22 having a rigid wall and an opening which is covered by a gas-permeable material (26). An active ingredient, such as potassium permanganate pellets (25) is retained in the container (22), for absorbing ethylene from the surroundings. The container (22) may comprise an array of recesses (24), each containing a single pellet (25) of the active ingredient. In use, the device may be included in a package of perishable produce, such as fruit. The device absorbs ethylene from the package, which retards ripening and deterioration of the produce.</p> |
