Development of an Oxygen Scavenger Unit for Food Preservation

摘要

Aquanautics investigate application of its oxygen removal technology in the areaof atmosphere control for food containers. Most foods remain fresher when stored under low oxygen concentrations. When carbon dioxide is added to the atmosphere of a food container, especially in the case of meats, spoilage is further reduced and freshness of appearance maintained. Produce respire consuming oxygen and producing carbon dioxide. Such respiration leads to ripening and finally food loss. Low levels of oxygen retard such respiration and help maintain freshness longer. In the case of meats, preservation requires both freezing and low oxygen content. If storage is effected under carbon dioxide, it is possible to transport and store meat without freezing, maintaining thereby its freshness. Controlling oxygen content in a food container requires dealing with oxygen ingress into the container due to two primary reasons: Leaks around gaskets in doors and other openings, and Periodic opening doors for access to food.
