Oranges can be frozen, though they do tend to lose a little texture and color through the process. Whole oranges freeze more successfully than oranges that have been sectioned or cut.
Whole oranges, orange segments and cut oranges can all be frozen successfully for up to six months. It's important to press as much air as possible out of the freezer bag before freezing the oranges. Frozen oranges must be defrosted at room temperature rather than in a microwave. If cut oranges are mixed with sugar and water, they can freeze successfully for up to one year. Freezing affects both the texture and the flavor of oranges, so it's best to use fresh oranges whenever possible.
