Air frying has become a popular method of cooking compared to deep frying. A major reason for this has been the numerous benefits for health-conscious consumers, as well as different cost-savings and safety improvements for foodservice operators.
Air frying as opposed to traditional deep frying has become a popular method of cooking. A major reason for this has been the numerous benefits for health-conscious consumers, as well as different the cost-savings and safety improvements over deep frying for foodservice operators.
What’s the difference?
Air frying is a dry cooking method much like roasting, baking, grilling, and frying. Compared to deep frying, the air frying process puts emphasis on water to create steam, instead of submersing foods in fatty oil, which has nearly doubled in cost and poses a safety risk for employees. There are three cooking periods with air frying to get a crispy brown, golden delicious product. What happens in each stage dictates the temperature at which to cook the product and the settings it needs:
- Settling period: This step starts with a sudden expulsion of steam at 212˚F, which is caused when the water releasing from the product comes in contact with oil. In air frying, oil is used as an ingredient rather than a cooking medium, since adding fat transfers energy quicker. High heat and air flow rid the water from the product, converting it to steam which then surrounds the food. In the case of a fryer, the product isn’t even touching the fryer yet during this stage.
- Constant rate period: Next is where the “cooking zone” begins taking place on the surface of the product. This dictates how hot the food will be. The water vapor repels the oil and keeps it from penetrating beyond the surface of the product. The steam cooks the surface, buying time for flavors to develop and for the heat to make its way to the center of the food without burning around the edges. This step makes up a majority of the process.
- Falling rate period: The final step is what is perceived as “frying.” The “cooking zone” from the previous step now moves internally in the food product. As a result, you receive a golden brown and delicious food item.
How to Adapt Food Products to Air Frying
- Cook Time – Here you will need to increase the time to cook your food product and allow water to evaporate throughout the cook. A temperature range of 400-450˚F should be the target.
- Air Flow – This is where you will increase air flow to allow water to evaporate and crisp the product. You can achieve a crispier product through elevation with racks, airflow with perforated pans, and the right fan speed. If your food sits below the rim of the sheet pan, it will inhibit the air flow from surrounding the product. With the racks, the air will wick the moisture away from the food product and speed up the second stage of air frying. Alto-Shaam offers racks and pans as accessories for air frying products to perfection.
- Add Oil– Rather than using oil as a cooking medium, air frying uses oil as an ingredient. The product must have oil, as it adds an insulator factor to the product and smooths it out. Here are the ideal fat contents to commonly fried foods:
- Chicken 15-47%
- French Fries 20-33%
- Fish 15-28%
- Onion Rings 20-30%
- Potato Chips 28-44%
- Donuts 25-35%
Expand Menu Offerings
Although not all products will work in an air fried food program, some are better than others. Alto-Shaam’s team of culinary experts will help work and support you with menu development and testing different cooking methods to perfect each item. For a perfectly crispy, golden-brown product, liquid battering foods is not recommended; however, perfect products for air frying are:
- Hand breaded items: Use oil, water, and breading methods with ingredients such as cornmeal, breadcrumbs, flour, and seasoning. This gives the starch in food something to grab onto. Adding a pre-dust to products also adds a layer of seasoning and flavor.
- Par fried, oven-able, or “air fryer ready” products: Some pre-made products on the market today take the step out of hand breading items yourself, saving time and labor. These include tater tots, hashbrowns, corn dogs, and beer-battered cod fillets.
- Longer cooking times. Air frying can often take longer than deep frying, due to how long it takes to move through the three phases of cooking. Luckily, with a Vector® or Converge® Multi-Cook Oven, the speed of cook is matched with an increased throughput thanks to the multiple, independent chamber design. Foodservice operators can turn just as much, if not more, product than a deep fryer with the ability to cook up to four batches of air fried food simultaneously in up to four independent ovens in one – all without flavor transfer between items!
- Proper holding. With multi-cook ovens, air frying food programs are successful with a focus on batch cooking. An essential component to batch cooking is the gentle, radiant holding equipment to increase efficiency and food quality right up until service. Alto-Shaam’s range of heated holding solutions include Halo Heat® to ensure crispy, golden brown fried foods stay at the exact same quality for hours. These units are less harsh than other methods of holding, as they operate with a radiant and precise thermal cable as opposed to added humidity, fans or calrods.
- Consistent Outcomes. With recipe programmability on the ovens, menu development is the key to finding the best settings and ingredients for an air fried food program. Alto-Shaam’s multi-cook ovens feature precise programmability and ChefLinc™ remote oven management, making menu development simple and easy in the early stages of setting up your program. Once the recipe is locked in, all employees need to do is load the oven with your product, select the recipe and walk away. Alto-Shaam has a full team of culinary experts and culinary partners to help you achieve the best crispy, golden brown and delicious air fried food!
