Below is a chart to help you determine the shelf life of food stored in air tight containers at constant temperature of 70 degrees. ** All of the following products will store proportionally longer at cooler temperatures if kept at lower storage temperatures. Shelf life of 30+ years is perfectly feasible for many products! | |||||

Predicting actual shelf life of dehydrated foods is not an exact science, however there have been many studies done. In addition to the above average shelf life of food stored at a constant 70 degrees, you can dramatically increase your life expectancy by lowering the constant temperature. It is possible to double, triple or even quadriple the shelf life by lowering the temperature proportionally. Some products, such as seeds, can even be frozen for dramatically increased shelf life. The basic rule of thumb is to store you food storage in as low of temperature as possible to increase its shelf life and to retain nutritional value. Products that contain yeast (leaven) should be considered as having a shorter shelf life then products that do not contain this ingredient. There are active enzymes in leaven, which create carbon dioxide gas, the same gas used in food storage (dry ice method). The gas is harmless to food. Leaven by itself has a 2 year shelf life (see Yeast above). |
