Can You Dehydrate Grapes in an Air Fryer? (Everything You Need to Know!)

I was wondering if you could take grapes and dehydrate them in an air fryer. I think it would be a cool experiment to see for myself, but the results seem like they will probably not come out exactly as expected.

This is a question that many people have been asking about air fryers since they became popular in 2017.

Air frying is the process of cooking food by circulating hot air within it instead of using a stationary heat source alone. So this got me thinking. I wanted to know if you can dehydrate grapes using an air fryer. So I went to the store, bought some grapes, and threw them into my air fryer set to dehydrate.

This is what I discovered.

Can you dehydrate grapes in an air fryer?

Yes. Dehydrating grapes will actually turn those grapes into raisins. In order to do this with an air fryer, you need to pick the grapes, wash and clean them, set them evenly on the air fryer tray, and set the temperature to 135 degrees Fahrenheit for approximately 36 hours. Most modern day air fryers will have a dedicated button labeled “dehydrate.”

How to dehydrate grapes in an air fryer

Let’s talk about exactly how you should dehydrate your grapes when using an air fryer. It’s a bit of a process, but trust me, the outcome turns out really well if you or someone who really enjoys raisin snacks.

Step 1: Pick your grapes

This is probably going to be one of the most important parts of the process of dehydrating your grapes. And that is picking the right grapes. The ones I picked were large, round, and hard. I like the hard grapes because they’re always much crunchier.

Step 2: Wash and dry your grapes

Make sure you wash your grapes well. If you got them from the store, there’s a chance that these grapes were sprayed with pesticides and God knows what else. It is important that you rinse and strain the water out of your grapes as much as possible. Also, don’t forget to dry your grapes by patting them down with a dry paper towel.

Step 3: Break the skin.

This can be done by either crushing or slicing them. The important thing to understand here is that you’re trying to dehydrate the grapes. And you can’t do that efficiently if the grapes are intact and surrounded by skin. The skin will prevent the moisture from inside the grape from leaving, preventing you from dehydrating your grapes. To make things easier, I recommend punching a sizable hole or creating lots of slits into the grape skin so that the heat will have access to the inside.

Step 4. Arrange your grapes on the dehydrator tray.

Place your grapes on the tray. Make sure you space them out and try to not allow them to touch each other. The train is usually filled with gaps, so take advantage of this and put each grape in its own separate gap. This will help with the heat circulation that goes on within the air fryer. Don’t layer any of your grapes on top of each other unless you have a rack that you can stack on top of each other.

Step 5: Set your air fryer at 135 °F for about 30 hours.

Dehydrating food requires that you set your temperature as low as it can be and cook the food for an extended amount of time. This actually helps release the moisture from the food, and in time, all the moisture will exit, leaving behind a shriveled dry grape, also known as a raisin.

Step 6: Check to see if your grapes are done.

When you’re checking to see if your grapes are done, you can simply touch them. If the grapes have a leathery texture, then it’s most likely done. You can continue air-frying it for a little while longer if you wish. But the goal here is to get rid of all the moisture from the grape. You can also do a taste test. It’ll most likely be chewy instead of packed full of juice. If you’ve ever eaten those raisins from a box, then you’ll know what I’m talking about. If you visualize the grapes, they should be wrinkly and shriveled up to almost one-third of the size that they used to be.

Step 7: Store your grapes

When everything has checked all the marks and your grapes are looking like amazing raisins, then it’s time to let them cool and then store them. I recommend storing your grapes in a vacuum-sealed, airtight container. But if you don’t have a vacuum-sealed container, you can always just use a regular container. However, I do strongly suggest that you find a container with an airtight lid. You don’t want moisture getting into the grapes because it can always invite microbes or spores from the air that cause mold or bacteria to grow on your raisins.

Sealing your raisins from the air can also keep your raisins fresher and last longer.

What happens if my dried grapes are too hard?

When you are done drying your grapes, they may still be too hard. Usually this would be a good thing but if you happen to over dehydrate your grapes then simply rehydrating them right before eating would be something I would suggest. You merely need to add a bit of water or soak them in a bowl for a minute or two. After you’re done I also recommend patting them down with a dry paper towel. I like to make sure they are completely dry because a wet and soggy raisin is never something you’d want to eat.

Do dried grapes turn brown?

It all depends on the type of grapes that you are dehydrating.

But let’s take the purple grapes. These grades will definitely get a bit darker after air frying. This is because of the Maillard reaction which causes a chemical reaction between amino acids and sugars that affects the color that results from cooking food. You’ve likely seen the crusted edges of a steak or the burnt ends of your pork chops. This is explained thanks to how the Maillard reaction works.

In the case of green grapes, you’ll likely see a bit of a darker green color that results from dehydrating them. Again the Maillard reaction is to blame for the changing color. It won’t necessarily turn brown, but in my experience you’ll likely see a deeper darker green.

What are the nutritional facts of dehydrated grapes?

One half a cup of grapes has 45 grams of sugar and almost one hundred calories. This is no different for dry grapes as well. The dry grapes will usually hold the same nutritional value minus the water. Grapes are also rich in other nutrients, such as vitamin C, potassium, folate, and manganese.

Dehydrated grapes contain a high amount of phenols and polyphenols. This is because they are rich in natural pigments, which are used to protect the grape from UV light damage.

Grapes also have antioxidants there are important for removing radicals in the blood. There might not be that much in a single grape but they do add up. Just be wary that the sugar content is pretty high and you should limit yourself to between 1 to 2 cups a day.

They also contain a natural anti-bacterial agent called raisin anthocyanins which fight against the bacteria that causes bad breath.

What are the uses of dehydrated grapes?

Dehydrated grapes are a great way to add nutrition and flavor to your morning oatmeal, as well as other types of recipes. They can be used as a salad topping, cereal or granola in many different recipes.

How long do you dehydrate grapes?

Grapes should be dried for 24-48 hours, and if left longer, it can become too hard to eat. But, if you don’t leave it in long enough you can end up with somewhere between a full grape and a raisin. And every bite you make will have a squishy inside. It isn’t exactly how raisins are supposed to taste.

I also recommend that you check up on your grapes at least two to three times during the process of dehydrating them for the next two days. You have to make sure that they are dehydrating appropriately.

Also, the length of time you have to dehydrate your grapes can vary depending on the size of your grapes and how much preparation you put into it. If the grapes are of the larger variety, then it might take several extra hours to get all the moisture out of it inside the air fryer. But if they’re tiny little grapes then it might not require as much time as you thought. And if you had left it in for too long it would have dried out or turned into a hard little pebble.

How long do raisins last?

In the best-case scenario, if you properly store and feel your dehydrated grapes in an airtight container, then your shelf life may likely be somewhere on the high end of six to 12 months. If you happen to open this container frequently or accidentally leave it open for several hours at a time oh, then it will likely end up going bad much sooner than that.

One thing I would like to add is that you should be aware that raisins, if left out, may end up getting moldy and sometimes it’s hard to see only because you’ve used the purple raisins that eventually just turn really dark. A lot of bacteria and mold are often dark colors but sometimes their lighter colors so it’s easier to see if you are dehydrated grapes have formed mold.

I recommend that if you do dehydrate your grapes and place them in an airtight container, then grab yourself a marker and write the date of when you made those raisins and perhaps write an expiration date 12 months from now. You can also leave these grapes in the fridge. Cold temperatures usually stop bacteria and mold from growing.
