Hulled & Pearled Barley, Oat Groats, Quick & Rolled Oats, Quinoa, and Rye: Soft Grains have softer outer shells which don't protect the seed interior as well as hard shelled seeds.  However, sealed in the absence of oxygen, they will still have a storage life of 25 years at a stable temperature of 65°F.

Buckwheat, Corn, Flax, Kamut, Millet, Durum Wheat, Hard Red Wheat & Hard White Wheat, Soft Wheat, Spelt, and Triticale: Hard Grains all store well because of their hard outer shell which is nature's near perfect container. Remove that container and the contents rapidly deteriorate. Wheat, probably nature's longest storing seed, has been known to be edible after scores of years when stored in a cool dry place. As a general rule for hard grains sealed in the absence of oxygen, plan on a storage life of 30 years at a stable temperature of 65°F.

Adzuki, Black Eye Beans, Black Turtle Beans, Garbanzo Beans, Great Northern Beans, Kidney Beans, Lentils, Lima Beans, Mung Beans, Pinto Beans, Small Red& White Beans, and Soy Beans: As beans age they lose their oils, resist water absorption and won't swell. Worst case, they must be ground to be used. Storing beans in nitrogen helps prolong the loss of these oils as does cool temperatures. Sealed in the absence of oxygen, plan on a storage life of 25-30 years at a stable temperature of 65°F.

Broccoli, Cabbage, Carrots, Celery, Onions, Peppers, and Potatoes: Dehydrated vegetables store well sealed in the absence of oxygen. Plan on a storage life of 20-25 years at a stable temperature of 65°F.

Cheese Powder, Cocoa Powder, Powdered Eggs, Butter & Margarine Powder, Morning Moo, Whey, and Instant & Regular Milk: Dehydrated Dairy Products generally store less because of fat content. If stored dry in hermetically sealed containers with the oxygen removed they will store approximately 5 years. If stored at a stable temperature of 65°F they may enable them to store up to 10 years. Instant and regular milks that are non fat will store 20 years.

All Purpose White Flour, Bakers Flour, Unbleached Flour, Whole Wheat Flour, Cornmeal, Mixes, Cracked Wheat, & Germade: After seeds are broken open their outer shells can no longer protect the seed contents and seed nutrients start to degrade. Don't try to store unprotected flours longer than a year. Sealed in the absence of oxygen, plan on a storage life of 5-10 years at a stable temperature of 65°F. They should keep proportionately longer if stored at cooler temperatures.

Macaroni, Edd Noodles, and Spaghetti: Pasta will store longer than flour if kept dry. Sealed in the absence of oxygen, plan on a storage life of 20 years at a stable temperature of 65°F. Pasta should keep proportionately longer if stored at cooler temperatures.

Apples, Bananas, Coconut, Raisens, Peaches, and Strawberries: Fruit that is dried well may keep as well as many dehydrated items. Sealed in the absence of oxygen, plan on a storage life of 25 years at a stable temperature of 65°F.

Honey, Salt, and Sugar: Honey, Salt, and Sugar should keep for many years if stored free of moisture. Watch out for additives in the honey. It is possible to buy honey with water and sugar added. This honey generally doesn't crystallize like pure 100% honey does when stored for a long time.  Honey can be warmed and melted down after it hardens. Avoid boiling honey as it will kill the nutrition.

Peanut Butter Powder: Peanut Butter Powder will not store as long as wheat flour. Hermetically sealed in the absence of oxygen, plan on a storage life of 3-5 years at a stable temperature of 65°F.

Brown & White Rice: Brown and white rice store very differently. Brown rice is only expected to store for 6 months under average conditions. This is because of the essential fatty acids in brown rice. These oils quickly go rancid as they oxidize. It will store much longer if refrigerated. White rice has the outer shell removed along with those fats. Because of this, white rice contains less nutrition but will store longer. Sealed in the absence of oxygen, plan on a storage life for white rice of 25-30 years at a stable temperature of 65°F. Stored in the absence of oxygen, brown rice will last longer than if it was stored in air. Plan on only 1 to 2 years if the temperature is kept cooler 50°F to 60°F.

Beef TVP, Chicken TVP, Ham TVP, Sausage TVP, Taco TVP, and Barbeque TVP: Textured Vegetable Protein, made from soy beans, has an unusually long storage life. Sealed in the absence of oxygen, plan on a storage life of 10 years at a stable temperature of 65°F. Some of these products contain a certain amount of moisture that will shorten the shelf life.
