Have you ever opened your freezer to find ice crystals and discolored patches on your frozen food? If so, you have likely experienced freezer burn. Freezer burn is a common problem that occurs when food in your freezer is exposed to air.
But how does this happen? When food is not properly sealed, the moisture inside the food evaporates and crystallizes. This creates ice crystals on the surface of the food, resulting in a dry and leathery texture. Additionally, the exposure to air causes the food to oxidize, leading to the discoloration.
So, why is your freezer causing freezer burn? There are a few potential causes. First, the temperature in your freezer may not be consistently cold. Fluctuations in temperature can cause the food to partially thaw and refreeze, leading to freezer burn. Second, improper packaging can also contribute to freezer burn. If your food is not tightly sealed or if there is excess air inside the packaging, the food is more likely to be exposed to air and develop freezer burn.
Fortunately, there are steps you can take to prevent freezer burn. First, make sure your freezer is set to the correct temperature. Most freezers should be set between 0 and -10 degrees Fahrenheit (-18 to -23 degrees Celsius). Next, properly package your food. Use airtight containers or sealable freezer bags to minimize air exposure. It’s also a good idea to wrap your food in plastic wrap before placing it in a container or bag.
By taking these steps, you can help preserve the quality of your frozen food and prevent freezer burn. Remember, frozen food can still be safe to eat even if it has freezer burn, but the texture and taste may be affected. So, it’s best to take preventative measures and enjoy your frozen food at its best!
