At 10 years, Spam has the longest shelf life of any food, according to food scientists who are experimenting with high-pressure processing to create fresh-tasting food that could be stored for 3 to 5 years to feed astronauts, soldiers and victims of natural disasters. Some day astronauts may be able to replace Tang with fresh Florida orange juice; but for now, Florida citrus storage is limited to a few weeks; although freezing can extend your enjoyment of fresh Florida oranges and grapefruit.
You can store Florida citrus fruit for up to a week at room temperature. To deter spoilage, keep Florida oranges and grapefruit out of direct sunlight in a cool, dark place. Room temperature fruit should be checked daily for spoilage. Thin-skinned tangerines should be refrigerated.
The life of Florida grapefruit, tangerines and oranges can be extended by several weeks by storing them in the refrigerator. Refrigerated fruit should be stored in the crisper drawer or in a mesh or perforated plastic bag to allow air circulation. Never store citrus fruit in airtight containers as trapped moisture can cause mold and spoilage. Before eating or juicing, refrigerated citrus fruit should be allowed to reach room temperature for best flavor and optimum juiciness.
Fresh-squeezed Florida citrus juice will maintain its flavor and vitamin C content if refrigerated immediately in a tightly-sealed container. Fresh Florida citrus juice, sectioned fruit in juice and grated citrus peel, called “zest,” can be frozen for later enjoyment.
