Freezer Burn and Air Put a straw into the bag and zip the bag around it. Suck as much air out through the straw as possible, then quickly remove it and seal the bag the rest of the way.
Preventing Freezer Burn
Proper Packaging: Wrap it right using airtight containers, heavy-duty freezer bags, or tight layers of aluminum foil or plastic wrap. The goal? Get rid of as much air as possible before sealing.
Food grade materials, such as aluminum foil, heavy freezer-weight plastic bags, heavy plastic wrap and parchment or freezer paper are excellent choices. It is safe to freeze meat or poultry directly in its supermarket wrapping, but this type of wrap is thin and lets air in.
Keeping your freezer door open too long can cause the compartment's temperature to fluctuate, increasing ice crystal formation that leads to freezer burn. Be sure to close the freezer door quickly after grabbing your favorite foods.
Foil is good as a moisture barrier to lessen the effects of freezer burn. I tend to wrap all my meat that I freeze in aluminum foil then put it inside of a ziplock bag. Freezer burn happens when frozen food goes through a (frost-free) freezer's defrost cycle and moisture builds up on the surface of meat.
The experts over at Ziploc told me that their freezer bags “are designed to protect in very low temperatures and harsh environments against punctures and tears.” So, in other words, while you can use a normal Ziploc bag to freeze food, chances are it won't escape the clutches of freezer burn and will be more prone to ...
Yes. You can use regular zip-top storage bags in the freezer. However, foods stored in these bags in the freezer might not hold up as well over long periods of time, and can be more prone to punctures and rips.
Conversely, you would not want to use parchment paper for freezing food because its lack of a coating would not protect your food well enough, or lock in the moisture needed to keep meats fresh. The bottom line is: think parchment paper for heat, and freezer paper for cold temps and maintaining freshness.
Most breads freeze very well with little to no loss in quality or texture. The enemy is freezer air, which can cause freezer burn and impart freezer-aroma flavors. To prevent this, wrap each loaf tightly in two layers of plastic wrap before placing it in a large resealable freezer bag.
Prevents Freezer Burn: For businesses that rely on frozen food storage, cling film is a lifesaver. It creates a protective layer that prevents freezer burn, which occurs when moisture within the food crystallizes. Freezer burn can degrade the quality of frozen items and lead to food wastage.
Food grade materials, such as aluminum foil, heavy freezer-weight plastic bags, heavy plastic wrap and parchment or freezer paper are excellent choices. It is safe to freeze meat or poultry directly in its supermarket wrapping, but this type of wrap is thin and lets air in.
If you are using plastic bags, make sure to squeeze out as much air as possible before sealing them. Label the containers with the date on some freezer tape so that you know when the items were fully frozen. Most fruits can last for up to six months if they are stored properly.
THE BOTTOM LINE For storing food in the freezer, use freezer bags because they are thicker and thus better at keeping moisture in and odor out. For general storage, freezer bags offer extra protection but regular storage bags are slightly less expensive.
Freezer Temperatures
The temperature of a freezer should be set at 0 degrees Fahrenheit so everything stays very cold. A freezer should be cold enough to keep food frozen and preserve it until they are ready to be cooked or reheated.
Finally, I think the freezer paper protects the meat better. It's easy to get all the air out when wrapping in paper - not so easy in a plastic bag. And meat - or anything else - keeps better in the freezer if it doesn't have air around it.
All three papers will work well if you thaw the food before separating it. However, if you need to separate frozen food, it's better to use freezer or parchment paper. They are more durable and tear-resistant compared to wax paper when either wet or dry.
Rigid containers made of plastic or glass are suitable for all packs and are especially good for liquid packs. Straight sides on rigid containers make the frozen food much easier to get out. Rigid containers are often reuseable and make the stacking of foods in the freezer easier.
Proper packaging helps maintain quality and prevent freezer burn. Aluminum foil, freezer paper, plastic containers, and plastic freezer bags will help food maintain optimum quality in the freezer. Plastic wrap alone will not provide enough protection by itself, but can be used to separate foods within another package.
Freezer burn is caused by improper freezing practices and/or exposure to air. All foods are susceptible to this effect, but foods with higher moisture content (meats, fruits, ice cream, etc.) will develop it more quickly. Even if something is frozen perfectly, though, it will likely develop freezer burn over time.
Timing differs from item to item, but vacuum sealing with a FoodSaver® machine can keep food fresh up to 5x longer when compared to ordinary storage methods. This applies to products that go into your freezer, fridge, or pantry.
The key to avoiding freezer burn is to protect the bread from air by wrapping it well and removing as much air as possible before placing it in the freezer. If you see large ice crystals inside of the wrapping, the texture or taste of the bread has been compromised.
If you are freezing food for a shorter period of time (2-3 weeks at most), you can wrap in unbleached butcher paper or waxed paper sheets or bags. Butcher paper doesn't seal the food as well as waxed paper, but it makes a good first-layer wrap. Double or triple for longer freezing periods.
Ziploc® brand bags made with polyethylene are a great choice for food storage, but should not be used for sous vide cooking (boiling in water) as the softening point is 230°F and boiling point for water is 212°F.
