Shelf life varies according to product and
storage conditions. Quality products that have been sealed and then stored in a
cool, dry location should last for many years. An exact shelf life is difficult
to calculate because of the many variables involved.
Wheat and sugar can be stored for many years under the right conditions.
Powdered milk, instant potatoes, and rice have a much shorter shelf life, but
should maintain most of their nutritive value for 3 years or more. Other
products that are recommended for food storage were chosen because they are
still nutritious after 5 to 10 years.
All food storage should be rotated. Oldest products should be used first to
maintain freshness. You can rotate food by using it yourself or by sharing it
with others
