Oranges can either be stored at room temperature or in the refrigerator, depending upon your preference. They will generally last close to two weeks, and will retain nearly the same level of their vitamin content. Keep oranges unwrapped in the refrigerator if you like to eat them cold. Avoid storing oranges in unperforated plastic bags as moisture trapped inside could encourage mold growth.

Orange juice and zest can also be stored for later use. Place freshly squeezed orange juice in ice cube trays until frozen, and then store them in plastic bags in the freezer. Dried orange zest should be stored in a cool, dry place in an airtight glass container.
