Freezer burn is the dehydration of the surface of frozen foods that results in a dried and leathery appearance. Freezer burn can degrade the flavor and texture of meat, poultry and other food stored in the freezer, leaving it discolored, unappetizing and even inedible.Freezer burn appears as grayish-brown leathery spots on frozen food. It occurs when air reaches the food's surface and dries out the product. This can happen when food is not wrapped securely in air-tight packaging. Color changes result from chemical changes in the food's pigment.
