Freezer burn is a common issue affecting frozen foods, particularly meat. It occurs due to two primary reasons: prolonged storage in the freezer, leading to water molecule migration, and inadequate wrapping, exposing the food to air. When food is in constant contact with air, water molecules evaporate, resulting in dehydration and, ultimately, freezer burn.
How Freezer Burn Impacts Different Food Types
The effects of freezer burn vary depending on the type of food.
Freezer burn and meat: Freezer burn alters the texture and appearance of meat. Red meats, such as beef, may turn a dull red-brown or grayish-brown, becoming leathery. This affects all cuts, from steaks to ground meat.
Poultry, including chicken, turkey, and goose, may develop a pale beige or grayish-beige color. De-skinned poultry, like breast meat, is particularly susceptible to discolored blotches along the edges, which may appear white and resemble fat. In some cases, freezer burn can create a honeycomb-like structure on the meat’s surface.
Freezer burn and fruits or vegetables: Fruits and vegetables have a higher water content than meat, making them more prone to freezer burn. For example, cucumbers and celery are about 95% water, strawberries are 91%, and cauliflower is 92%.
While their high water content makes them suitable for flash freezing, long-term freezer storage can lead to dehydration. Water continuously migrates out of frozen fruits and vegetables, resulting in dried-out and flattened pieces. The more the ice moves, the greater the damage it causes.
Freezer burn and ice cream: Ice cream and other frozen desserts are also susceptible to freezer burn. Unlike meats, fruits, and vegetables, ice cream doesn’t typically discolor. Instead, it develops a thick layer of ice crystals and loses some of its flavor. Additionally, it loses its creamy texture and can have ice crystals throughout.
Is Freezer-Burned Food Safe to Eat?
Food affected by freezer burn remains safe for consumption. Freezer burn primarily affects the food’s quality by reducing moisture and diminishing flavor. However, it doesn’t compromise the safety of food.
Nevertheless, it’s essential to avoid consuming meat or any food that exhibits a foul odor or other signs of spoilage. Spoiled food is unsafe to eat. It’s best to discard anything that shows such signs, even if it appears to only have freezer burn in some areas.
