For longer-term needs, and where permitted, gradually build a supply of food that will last a long time and that you can use to stay alive, such as wheat, white rice, and beans.
These items can last 30 years or more when properly packaged and stored in a cool, dry place. A portion of these items may be rotated in your three-month supply. Estimated shelf life for many products has increased to 30 years or more see chart below for new estimates of shelf life. Previous estimates of longevity were based on "best-if-used-by" recommendations and experience.
Though not studied, sugar, salt, baking soda essential for soaking beansand vitamin C in tablet form also store well long-term. Some basic foods do need more frequent rotation, such as vegetable oil every 1 to 2 years. While there is a decline in nutritional quality and taste over time, Food product hookup and storage times on the Food product hookup and storage times quality of food and how it was processed, packaged, and stored, the studies show that even after being stored long-term, the food will help sustain life in an emergency.
You may also want to add other items to your longer-term storage such as sugar, nonfat dry milk, salt, baking soda, and cooking oil.
To meet nutritional needs, also store foods containing vitamin C and other essential nutrients. These containers, used with oxygen absorber packets, eliminate food-borne insects and help preserve nutritional quality and taste.
Under certain conditions, you can also use plastic buckets for longer-term storage of wheat, dry beans, and other dry products. Botulism poisoning may result if moist products are stored in packaging that reduces oxygen.
Dry products that are not suitable for longer-term storage due to moisture content, oils, or other concerns include:. Bottles made of PETE polyethylene terephthalate plastic can be used with oxygen absorbers to store products such as wheat, corn, and dry beans. Other types of plastic bottles typically do not provide an adequate moisture or oxygen barrier for use with oxygen absorbers.
Do not use containers that were previously used to store nonfood items. PETE bottles can also be used for shorter-term storage up to 5 years of other shelf-stable dry foods such as white rice.
Moisture content of stored foods should be about 10 percent or less. When moist products are stored in reduced oxygen packaging, botulism poisoning may occur. Oxygen absorber packets are available online at store.
Unused oxygen absorbers can be stored in glass jars with metal lids that have gaskets. Oxygen absorbers protect dry foods from insect damage and help preserve product quality.
They are used when dry foods are packaged in sealed containers. Oxygen absorbers are small packets that contain an iron powder.
The packets are made of a material that allows oxygen and moisture to enter but does not allow Food product hookup and storage times iron powder to leak out.
Moisture in the packaged food causes the iron in the oxygen absorber to rust. As it oxidizes, the iron absorbs oxygen. Oxygen absorbers rated for cubic centimeters cc of oxygen work well for properly packaged dry food in containers of up to one-gallon capacity 4 liters. Oxygen absorbers remove oxygen more effectively than vacuum packaging. Air is about 20 percent oxygen and 80 percent nitrogen.
Absorbers remove only the oxygen. The air left in the container is mostly nitrogen and will not affect the food or allow the growth of insects. Products should be low in moisture and oil content.
If the moisture content is not low enough about 10 percent or lessstoring products in reduced Food product hookup and storage times packaging may result in botulism poisoning.
Oxygen absorbers should be used with containers that provide an effective barrier against moisture and oxygen. The following containers work well:.
Foil pouches such as those provided by Church home storage centers and available from store. Oxygen absorbers are not an effective treatment method for plastic buckets, milk bottles, or other types of plastic bottles not identified as PETE or PET under the recycle symbol see right.
What type of pouch is available at home storage centers, at Distribution Services, and online at store.
The pouches are made of multilayer laminated plastic and aluminum. The material is 7 mils thick microns and protects food against moisture and insects. Botulism poisoning may result if moist products are stored in oxygen reduced packaging.
Each pouch holds 1 gallon 4 liters of product. The weight varies by product.
