How do I Dry Dates?

I. Ong

The most traditional way to dry dates is to leave them out in the sun for a prolonged period of time. Though this method is the most straightforward, it also tends to be somewhat inconsistent — the results depend on the specific weather conditions, as well as the size and moisture of the fruit. Using a professional food dehydrator is usually the best way to ensure standard results. People who do not want to invest in one of these appliances can sometimes get similar results by slow-drying dates in a warm oven. An important part of the process is finding a method that works for you, then experimenting until you get just the right results.

Sunlight Drying

People who live in date-growing regions have dried the fruit using only sunlight for centuries. In most cases, simply setting the dates outside on a tray for a prolonged period of time — usually several days — will cause them to shrivel and dry. Slicing them in half and removing the tough central pit often speeds the process.

If you're using this method, it's usually a good idea to dry dates under some sort of screen or protective shield to prevent contamination by birds or insects. A number of farms and food manufacturers sell drying screens, but fancy is not always necessary. Even setting the fruits on an enclosed porch or breezeway is usually sufficient, so long as they are still getting direct sunlight.

Dates tend to grow in hot, almost desert-like climates where the sun shines intensely for most of the day. If you live in a cooler or moister place, sunlight drying might not be as successful. At the very least, you may find yourself constantly moving the fruit to the warmest places.

Using a Food Dehydrator

A professional food dehydrator is often the fastest way to dry dates, though it can also be the most expensive. Commercial dehydrators are often very large, sometimes the size of an entire room; home-use models are typically much smaller, and can usually fit on a countertop. They work by controlling the atmosphere and air quality, artificially creating a very arid environment. At the same time, they mechanically suck moisture out of the drying chamber, often dehydrating dates and other foods in a number of hours.

The Warm Oven Approach

Buying a food dehydrator is often very expensive, and unless you are planning to dry a lot of things, it may not be a good choice for you. Instead, you can try putting the dates in a warm oven. Heat it to about 150°F (about 66°C), and arrange the fruit on a baking sheet lined with parchment paper to prevent sticking.

The fruit should be left to dry for about a day. It is usually a good idea to shut the oven’s power off intermittently, as the idea is not to cook the dates but rather to dehydrate them. Additionally, it's best to not leave an oven on long stretches of time. Check on the dates periodically, and turn them every few hours to make sure that all sides are exposed to the heat evenly.

Vitamins and Other Additives

Some dried fruit experts recommend coating dates in a concentrated vitamin C mixture in order to help them keep an attractive appearance after drying. The vitamin helps improve the elasticity of the fruit’s skin, and can lead to a shinier, more appealing dried fruit. Vitamin additives may also help speed the dehydration process by wicking moisture from the inside out.

The easiest way to add vitamin C is to soak the fruit in a mixture of vitamin C powder, which is commonly sold in health food stores, and water. Breaking open a few oil-based vitamin capsules may also work.

General Tips and Tricks

It is always important to carefully select the dates you will use in drying. They should be fully ripe, but should not show any signs of spoilage. Thoroughly washing and drying all fruits before you begin will reduce the chance of contaminants.

Paying attention to the pit is also important. Dates can be dried whole quite successfully, but the process is often a lot faster if the thick inner pit has been removed. Most food processing facilities have machines that will automatically pit the fruit, but you can achieve similar results at home with a paring knife and a bit of patience.

@mobilian33 - Dry dates can last longer in a refrigerator than fresh ones, so using one of the drying methods mentioned in this article could help you save your dates for longer. On average, a dried date should last for about a year when you place them in an airtight container like you do your fresh dates.

You might also want to consider freezing the dates. You could freeze a fresh date in your freezer and it would remain usable as long as a dried date in the refrigerator. However, if you really need for the dates to last a long time then dry them and then freeze them. They can last for years when prepared this way.


I have a friend who decided to plant date trees. This was a good many years ago when she first planted them. Over the years, she had a tough time actually getting trees to grow. She used both date seeds and whole dates and the seeds eventually worked better.

Now, after a lot of time and work, she finally has trees that produce dates. She has so many dates that she is always giving them away and I have more than I can use before they spoil, so I keep them in the refrigerator in airtight containers. The fruit can last me for over half a year in the containers, and I like being able to have them whenever I like to use in recipes or just to eat.

Anyway, I am getting to the point that some of the dates are going bad before I can use them, even when they are refrigerated. This is why I am considering dry dates. Does anyone know how long dried dates can last in a refrigerator?
