How Long Do Dried Orange Slices Last? Do They Go Bad?

There are many ways to eat oranges but the uses of dried orange slices are even more. You can enjoy dried orange slices all over the year. But how long can you store? What is the best way to store it? Let’s learn in-depth.

How long do dried orange slices last? Do they go bad?

Dried orange slices can last about 2 years if dehydrated and stored properly. For eating, 2 years is a standard limit as it can be smelly afterward. For decorating, one can use it until the color does not fade. If not dehydrated or stored properly it can go bad by developing mold.

Dried orange slices last for a long time. The dehydration process takes up all the water from the orange. So bacteria, yeast, and molds can not colonize as they need water to live. This is why dried oranges can last over two years if stored well.

However, after dehydration, the nutrient content stays almost the same for years. As dried orange slices don’t contain any water they can’t go bad easily. Only if it gets moisture, it can create opportunities for microbes to colonize.

So, it should be kept in an airtight container so that it doesn’t get worse from the air moisture. You may think the container itself has air in it, but the air does not have enough moisture to make it bad. 

Most dried fruits can be stored for about 4 to 12 months. But oranges are different. Dried orange slices have a high volume of citric acid which makes it hard to colonize for most bacteria. 

Is there any difference between oven-dried and dehydrated orange slices? Let’s see.

Oven-dried orange slices:

Ovens heat cooks the orange slices a bit before dehydrating. The slices turn brownish in the oven. You need less time to dry orange slices in the oven. Can be stored like any other orange slice.

Dehydrated orange slices:
