Not too long ago infrared cooking technology was only available to commercial food service business. In 2000 infrared cooking technology was release to companies that make consumer products and as time has passed more companies are making grills and ovens that utilize infrared energy for cooking purposes.
Infrared is a light that is just below the red end (low end) of the visible spectrum. Just like radio waves or x-rays we cannot see infrared but we can feel it as heat. Just like some of the other non-visible light waves like microwave or radio waves; infrared has specialized properties that make it ideal for cooking. Infrared waves penetrate organic material, causing the molecules to move which creates friction and energy as heat.
Ok so how does infrared cooking technology make for good cooking? There are three types of heat transfer used in cooking; conduction, convection and radiation. Conduction is when you cook something by applying heat direct to the food item through the food item and some other heat conducting surface such as a frying pan when searing a steak. Convection transfers heat through air or water such as oven roasting or boiling. Convection used in ovens first heats the air then the air actually cooks the food. Radiation does not rely on any secondary element to transfer the heat. Radiation works directly on the molecules of the food providing a more efficient heat source.
Infrared Cooking Technology Benefits
The benefits of cooking with infrared cooking technology are many. First moisture is retained in the food as the radiant energy cooks evenly through the food item. On a grill or in the oven the air cooks the food from outside in, evaporating moisture as it goes. Infrared cooking devices heat up quickly virtually eliminating any prep or warm up time. Infrared cooking imitates the same type of heat created by open flame as seen by the color of the flame or heat element (orange to red) with the naked eye. A gas grill produces a blue flame which is different temperature than a red flame. Being able to cook an item in less time retains more vitamins and minerals as they do not escape with the evaporating moisture.
Infrared for cooking has many benefits and has been around long enough that it shows it is not just a passing fad. One of the most efficient means of cooking infrared cooking technologies allow grills to deliver great tasting and nutritious food items.
