Freezer Burn

Freezer burn is a food-quality issue, not a food-safety issue. It appears as grayish-brown leathery spots on frozen food. It occurs when air reaches the food's surface(because of non-airtight packaging) and dries out the product.

When you freeze food, the water molecules in it form into ice crystals. If one spot on the food is colder than the others, the water molecules will migrate and form ice crystals on the coldest spot, leaving the other parts dehydrated.

What you can do:

Keep the freezer temperature as constant as possible. Temperature fluctuations can also cause freezer burn. The difference in temperature between the solid food and the air surrounding it encourages freezer burn. Try to not open the freezer unless you have to and, when you do, don't linger with the door open.

Fill plastic containers with water and put them in the freezer. Make sure there's room for expansion. This will help stabilize the temperature in the freezer.

Don’t put hot food directly into the freezer. Sticking hot food in the freezer can cause a drastic change in temperature. Put it in the refrigerator first to let it cool before freezing.

Keep the temperature in your freezer below 0 degrees Fahrenheit. Freezer burn only happens when temperatures fluctuate above 0 degrees.

Package food tightly. When the surface of food is exposed to air, the water molecules have a chance to sublimate and migrate. When you're getting food ready for the freezer, try to make sure as little of the surface is exposed as possible. Consider purchasing a foodsaver vacuum sealer.

If you do not have a vacuum sealer, take extra time to press the air out when you seal the packages by putting a straw into the bag and zipping the bag around it. Suck the air out through the straw then seal.

Don't store food in the freezer for too long. The more time food spends in the freezer, the greater the chance of freezer burn.

Write the date you put it in the freezer on the package.

To avoid freezer burn in ice cream, wrap the container in aluminum foil or plastic wrap with the lid off, then replace the lid.
