Air Fryer Food Dehydrator: Is It Possible?

Air fryers are a popular kitchen appliance used to cook food by circulating hot air around it. While they are a convenient and healthy way to prepare meals, one common issue is that food can sometimes turn out dry. This happens because the high-speed circulation of hot air can rapidly evaporate the moisture from the food. However, it is possible to use an air fryer to dry food intentionally for dehydration or decorative purposes. Many air fryers have a built-in dehydrate function, and even those without this setting can be used for dehydration by adjusting the temperature and time settings.

Fan speed and temperature settings

Fan Speed Settings:

• High Fan Speed: This setting is ideal for crisping the exterior of your food while keeping the interior tender and moist. It is perfect for foods like french fries, steak, or bacon. However, lightweight foods may move or be displaced at high fan speeds.
• Medium Fan Speed: Medium fan speed is recommended for cooking frozen products. It provides a more balanced cooking process, preventing the food from burning on the outside while remaining undercooked on the inside. This setting is suitable for cooking bacon, wings, or toast.
• Low Fan Speed: Low fan speed is specifically designed for dehydration. It provides a gentle and controlled cooking environment, making it ideal for drying foods that progressively lighten as they lose water. This setting ensures even heat distribution and prevents lightweight foods from blowing around the basket during dehydration.

Temperature Settings:

• Dehydration Temperature: Dehydrating foods typically requires a temperature range between 150°F and 200°F. This lower temperature range ensures that the food dries out without being cooked.
• Moderate Temperature: For drying lean meats or delicate vegetables, a moderate temperature of 350°F to 375°F (175°C to 190°C) is recommended. This temperature range cooks the food thoroughly without causing excessive moisture loss.
• High Temperature: While a high temperature setting can create a nice crust, it may also lead to dryness in the interior of your food. Therefore, it is important to balance the temperature with the fan speed to prevent over-drying.

It is important to note that the specific fan speed and temperature settings may vary depending on the model and features of your air fryer. Always refer to the manufacturer's instructions and guidelines for your particular air fryer model. Additionally, experimenting with different settings and making adjustments based on your observations will help you find the optimal combination for drying food in your air fryer.

Dehydrating vs cooking

Dehydrating and cooking are two very different processes, each with its own benefits and drawbacks. This section will outline the key differences between the two and provide insights into when to use each method.

Dehydrating is a food preservation technique that has been used for thousands of years. It involves removing moisture from food, typically by circulating warm air through racks of food or using sun or air drying methods. The primary purpose of dehydrating is to extend the shelf life of food, making it last longer without refrigeration. Dehydrating can also reduce the weight and bulk of food, making it ideal for camping and backpacking trips. Additionally, dehydrated foods can be stored in airtight containers and placed in cool, dry areas, further extending their shelf life.

On the other hand, cooking is the process of preparing food for consumption using various methods such as frying, baking, boiling, or steaming. Cooking often involves adding moisture and heat to transform raw ingredients into edible dishes. While cooking does not necessarily extend the shelf life of food, it can enhance the flavour, texture, and nutritional value of the ingredients used.

One key difference between dehydrating and cooking is the level of moisture in the final product. Dehydrating aims to remove as much moisture as possible, typically reducing the food's moisture content to between 5% and 20%. This low moisture level inhibits the growth of bacteria, yeast, and mould, preventing spoilage and extending the food's shelf life. In contrast, cooking may involve adding moisture, such as through steaming or boiling, or retaining moisture through methods like frying or baking.

Another distinction between the two processes is the temperature range typically used. Dehydrating often occurs at lower temperatures, usually between 120°F and 200°F, to slowly remove moisture without cooking the food. In contrast, cooking temperatures can vary widely depending on the method and ingredients used but often involve higher temperatures, such as 350°F to 375°F for frying or baking.

Additionally, the types of foods suitable for dehydrating and cooking can differ. Dehydrating is ideal for foods like fruits, vegetables, lean meats, and herbs, as these items have a high moisture content that can be reduced through dehydration. On the other hand, cooking methods can be applied to a wider range of ingredients, including those with high fat or oil content, which are not suitable for dehydration as the fat can go rancid.

In terms of equipment, dehydrating typically requires a dehydrator, oven, or air fryer, while cooking can be performed using various tools such as pots, pans, ovens, or stoves, depending on the method chosen.

In summary, dehydrating is a food preservation technique that removes moisture to extend shelf life, reduce weight, and inhibit spoilage. Cooking, on the other hand, involves preparing food for consumption using various methods and temperatures. Dehydrating is ideal for moisture-rich foods like fruits and vegetables, while cooking offers more versatility in terms of ingredients and flavours. Ultimately, both methods have their advantages and can be used to create nutritious and delicious dishes.

Pros and cons of air fryer vs dehydrator

How to prevent food from drying out

Air fryers use rapid air circulation to cook food, which can result in the food drying out. Here are some tips to prevent this from happening:

Understand the Air Fryer's Cooking Principle

The high-speed circulation of hot air can cause the moisture in your food to evaporate quickly, leading to dryness. This is more likely to happen with foods that have a low-fat content, such as lean meats and vegetables.

Choose the Right Ingredients

Select ingredients that have a higher fat content or natural moisture, such as chicken thighs, salmon, or marinated vegetables. These types of foods are less prone to drying out during cooking.

Prepare Your Ingredients

Before placing your food in the air fryer, marinate your meats or vegetables with oil-based marinades. This will create a protective layer that helps lock in moisture. You can also lightly coat your ingredients with oil, even if you're trying to reduce your fat intake, as this will help prevent dryness.

Master Temperature and Time Control

Avoid setting your air fryer to the highest temperature, as this can dry out the interior of your food. Instead, use a moderate temperature between 350°F to 375°F (175°C to 190°C) for lean meats or delicate vegetables. Cooking time is also crucial—avoid leaving your food in the air fryer for too long to prevent overcooking and dryness. Check your food regularly and adjust the cooking time according to the thickness and type of ingredient.

Use the Air Fryer Correctly

Ensure that your food is arranged in a single layer in the air fryer basket, with enough space between pieces to allow for even air circulation. Shaking or flipping your food halfway through the cooking process will also help ensure even cooking and prevent dryness. Avoid overcrowding the basket, and consider cooking in smaller batches if necessary.

Enhance Moisture

Lightly spray your food with oil before cooking to create a barrier that locks in moisture. You can also use foil or parchment paper to create a pouch for foods that are more prone to drying out, such as fish or marinated vegetables. Adding a small amount of water to the bottom of the air fryer basket can also help maintain a humid environment and reduce the chance of food drying out.

Foods to avoid in an air fryer

Air fryers are a popular kitchen appliance, often used to cook healthier meals. They work by rapidly circulating hot air to achieve a 'fried finish' without the need for large amounts of oil. However, this rapid circulation of hot air can also cause certain foods to dry out, burn or crisp too quickly.

Lean Pork Chops or Tenderloin

Boneless pork chops and tenderloin are lean, meaning they have a low fat content. As a result, they can easily dry out in an air fryer. Fattier cuts of pork, such as bacon, bone-in pork chops, or those with the skin on, are better suited to air frying as they have a higher fat content and are less likely to dry out.

Spinach and Leafy Greens

Leafy greens such as spinach, kale and chard are not recommended for air frying. The hot air will crisp these delicate leaves far beyond the point of edibility. It is best to cook leafy greens using methods such as sautéing, stewing or steaming.

Steak

While steak can be successfully reheated in an air fryer, cooking it from raw in an air fryer is not advised. This is because air fryers cannot reach the high temperatures required to properly sear a steak. Steak cooked in an air fryer may end up tough and rubbery.

Unbreaded Chicken Breasts

Chicken breasts that are unbreaded have very little fat and will dry out easily in an air fryer. Breaded chicken, on the other hand, cooks well in an air fryer as the breading provides a protective layer, helping to lock in moisture.

Large Cuts of Meat

Large cuts of meat, such as pot roasts, are generally best cooked using low and slow methods like braising or smoking. Air fryers are not ideal for cooking large cuts of meat as the hot blast of convection air can dry them out.

Broccoli

When cooked in an air fryer, broccoli can dry out and become chewy and bitter. Roasting in an oven or air fryer with an oven extension is a better way to achieve crunchy, crispy broccoli florets.

Shellfish

Shellfish like clams and mussels need to be cooked with liquid to prevent them from drying out. They are also easily overcooked, which can result in a chewy, rubbery texture. It is best to avoid cooking shellfish in an air fryer.

Baked Goods

The nature of the heat in an air fryer can make baking unpredictable. Baked goods such as cakes, cookies and muffins can dry out and burn easily in an air fryer. It is recommended to use recipes specifically designed for air fryers rather than traditional oven recipes.

Popcorn

Popcorn kernels require a very high temperature to pop and most air fryers will not reach this temperature. Popcorn kernels can also become lodged in the air fryer's heating element, creating a fire hazard.

Raw Rice and Other Grains

Raw rice and grains should not be cooked in an air fryer as they require boiling or steaming to cook properly. An air fryer is better suited to reheating leftover rice and grains or adding a crispy finish to already cooked grains.
