Freezing is one of the easiest and least time-consuming methods of food preservation. Most foods retain their natural color, flavor, and nutritional value better than other methods of preserving food. However, a freezer can be a major investment and space is limited. If there is an extended power outage, food can be lost.
Frozen foods change in texture after thawing.
Freezing does not destroy bacteria. Spoilage can occur in frozen foods if the freezing does not take place rapidly, or when the freezer temperature gets above 0 F. Be sure to use wide flat containers to freeze the food more rapidly. When thawing food, remember that freezing does not destroy any spoilage organisms that were present in the food. When frozen foods are thawed slowly at room temperature, the surface warms up to a temperature where the bacteria can grow again even if the center of the food is still frozen solid. For this reason, thaw all foods in the refrigerator.
