Fruit

Fruits are placed in the refrigerator unwashed, peeled, in one piece. Most of the fruit stays fresh in the refrigerator for about three days, until the apples, pears and citrus fruits will stay fresh much longer. Cooling, bananas may darken, but this will not affect their freshness. Apples, pears and plums should be kept separately in paper or plastic containers because promote faster rotting fruits. Lemons can be stored in a jar full of water, in the cold. Apples should be kept apart, because they encourage ripening of other fruits and vegetables.

Storing oil in plastic dishes should be avoided, and the most appropriate for keeping a bottle of dark glass in a cool, dark place. Flour, sugar, cereals, pasta and beans are kept in a tightly closed glass jars in a dry place. Honey is one of the few foods that have an unlimited shelf life. He has a natural preservative.

Perishable foods like eggs should be stored in the coldest part of the refrigerator, not in the door. Eggs are preferably left in the original package, as the temperature in it is lower.

Spices

Green, parsley, dill, celery, except in plastic bags in the refrigerator can stand and wrapped in a damp cotton cloth or kitchen paper. These plants can also be frozen, so that it is used in cooking. Dried herbs should be kept in the dark bowl, on a dark and dry place. They will not coagulate if it put a few grains of rice that will draw all the moisture.

Tomato loses flavor in the fridge, cucumber is best kept in paper bags, carrots in plastic bags with holes, and the onions and potatoes in a cool, dark place. Vegetables prior to placing it in the freezer and packaging in sachets best first frozen on a tray. Root vegetables to remove the green part, the longer it will last.

Water

Commercial bottled water has an extended shelf-life of one to two years due to extensive water treatment (filtration, demineralization, and ozonation) and strict environmental controls during manufacturing and packaging. Bottled water should be stored in a cool, dry place in the absence of sunlight. Household tap water has a limited shelf-life of only a few days due to the growth of microorganisms during storage. Therefore, consumers should purchase bottled water if planning to store water for extended periods. The Food and Drug Administration (FDA) regulates commercial bottled water as a food.

Useful advice

When the power goes out in the home, minimize opening the refrigerator and freezer. Refrigerators and freezers are insulated, aiding in keeping foods cold to extend the shelf life of food. However, if the refrigerator or freezer door is opened often, the cooling will be lost. Perishable refrigerated foods (i.e. foods of animal origin) should be discarded after a 6-hour period. Using block ice may increase shelf-life of refrigerated foods. Food stored in fully loaded freezers may last for approximately two days, whereas food stored in partially loaded freezers may last for only one day. Freezer foods may be refrozen if ice crystals are present. Exceptions include ice cream, pizza, and casseroles. If the frozen food has completely thawed but is cold, it must be cooked within a 24-hour period; or foods may be refrozen within 24 hours after thawing. However, quality may be diminished. If in doubt about when the food actually thawed in the freezer, discard the thawed food. Dry ice may be used to keep frozen foods frozen and cold foods cold. Be careful not to handle dry ice with bare hands or breathe the vapors.
