Some foods keep better than others over long periods.
It stands to reason that if disaster strikes, you may not to be able to run over to the supermarket and pick up something for dinner that night. It may be some time before any resources, such as food and water, are available at all. Survival will depend upon the supplies you have on hand. Knowing the shelf life of emergency food will help ensure that supplies are always fresh and uncontaminated.
Longest Lasting
Honey has the longest shelf life of any food. According to Karen Sweet of homestead.org, when archeologists dug up the remains of King Tut in Egypt, they found honey that was still edible. You can use honey in place of sugar. It has medicinal purposes, doesn't crystallize and contains vitamins A, C, D, E, K and more.
Up to Three Years
Next in longevity are grains, dry dairy products, dried peas, beans and lentils. According to Judy Harrison and Elizabeth Andress of the University of Georgia, wheat, rice, rye, oats, triticale (a cross between wheat and rye), barley and millet and pasta products can be stored up to three years. Vegetable oils, corn, baking powder, soybeans, instant coffee, tea, cocoa, salt, bouillon products and powdered milk (in nitrogen-packed cans) will also last up to three years.
Six Months to One Year
Foods that can be kept up to one year are vegetable soups and canned, condensed meat. Canned fruits, fruit juices and vegetables, uncooked instant cereals (stored in metal containers), ready-to-eat cereals, canned nuts, peanut butter and jelly will last up to a year, as well. You can also store hard candy and chocolate bars up to one year. Potatoes, crackers and dried fruit (both stored in metal containers) and boxed powered milk will all last as long as six months, according to Harrison and Andress. You can also buy commercially packaged, freeze-dried, or air-dried meat and other survivalist food. The shelf-life will be listed on the packaging.
Water
Survivalist Terri Steffensen warns that an emergency water supply should be checked every three to six months for changes in appearance, scent, taste and leaks in the container. A good rule of thumb is to rotate your stored water and not let it sit any
Storage
Store your disaster food supply in airtight plastic or glass containers in a cool place. All containers should be stored off the floor. Water quality specialist Dorothy Miner recommends that water be stored in food-grade plastic or glass containers with tight-fitting lids. Purchase new plastic containers for water storage in department stores, at water vending machines and at sporting goods/survival stores. In a pinch, use
