Editor’s note: Adding to Ralph Graner’s ideas for freezing foods for easy fixin’, here’s a little extra freezin’ foods wisdom from Alice Henneman, MS, RD, Extension Educator and Dietitian with the University of Nebraska-Lincoln Extension in Lancaster County, and Joyce Jensen, Registered Environmental Health Specialist with the Lincoln-Lancaster County Health Department.
STEP 1. Cool foods “slightly” at room temperature before refrigeration. It is not necessary for a food to be completely cool before it is refrigerated. To help food cool slightly before refrigeration:
• Place a shallow container of food on a cooling rack to allow air to circulate all around the pan for about 20 to 30 minutes.
• Limit depth of food to 2 inches.
STEP 2. Complete cooling of foods in the refrigerator. Cool foods to refrigerator temperature before bagging them for your freezer. It is OK to refrigerate foods while they’re still warm. LOOSELY cover food upon refrigeration. This allows heat to escape and protects the food from accidental contamination from other foods during cooling.
STEP 3. Pack foods into freezer bags. Use “freezer” bags, not “storage” bags, for storing food in the freezer. Freezer bags are thicker than storage bags and will keep the food fresh longer. Speed freezing and hasten thawing by freezing foods in a thin, flattened shape in freezer bags. A rounded shape takes longer to thaw through to the middle. Flatter packages also will stack better in your freezer. To avoid getting food on the outside or stuck in the closure of the freezer bags, use a wide-mouth funnel (available in the kitchenware section of many stores).
Place the freezer bag in a container such as a quart measuring cup. Standing the bag upright also helps if you are filling the bag with a more liquid-type food. You may wish to double-bag liquids as an added precaution against leakage. Open the top of bag and enclose the edges around the bottom of the wide-mouthed funnel. Add food, in desired amount, through the funnel. Hold edges of the bag in place as needed. OR use some type of scoop — such as a measuring cup with a handle — to transfer the food to the freezer bag.
STEP 4. Label foods. To avoid mystery meats and other foods of unknown age and possibly origin, label foods using freezer tape, gummed freezer labels or permanent marking pens/crayons. Include:
• name of food;
• packaging date;
• number of servings or amount;
• additional helpful information, such as form of food (sliced, chopped, etc.), any special ingredients.
It is helpful to place filled freezer bags on a flat surface in your freezer, such as a metal pan. Do not stack freezer bags until frozen so they will freeze faster. After they are frozen solid, the bags may be removed from the pan and stored, stacked, directly on the freezer shelf. Or turn them on their edge and store them vertically. This is an especially good idea when freezing liquid foods, such as soups and stews.
STEP 5. Thaw and cook frozen foods. DO NOT thaw perishable foods at room temperature. If perishable foods are left at room temperature too long, bacteria may grow and produce heat-resistant toxins that can cause foodborne illness. Cooking may not be able to destroy these toxins.
It’s best to plan ahead for slow, safe thawing in the refrigerator. Small items may thaw overnight in the refrigerator. Up to five pounds of food should thaw in about 24 hours. If there is the possibility a thawing package might leak, you may want to thaw it on a plate or a pan.
If food is thawed in the microwave, finish reheating it right away. Unlike food thawed in a refrigerator, microwave-thawed foods reach temperatures that encourage bacterial growth. Cook immediately to kill any bacteria that may have developed and to prevent further bacterial growth.
Food may be transferred from a freezer bag to a microwave safe container for thawing in the microwave. If the freezer bag manufacturer says it is OK to thaw foods directly in their freezer bag, follow manufacturer’s directions for such things as venting, recommended heat settings, types of foods suitable for microwave-thawing, etc., for that specific bag. Also, follow manufacturer’s directions for your microwave.
While you may be able to satisfactorily defrost food in some freezer bags in the microwave (check manufacturer’s directions), DO NOT cook the food in the freezer bag — unless recommended by the microwave manufacturer. At the higher temperatures used in the microwave cooking process, it is possible for the plastic to reach melting temperatures.
