You might want to check some websites from the Church of Latter Day Saints (Mormon).

About 15 years ago, one of my friends father was an elder in the LDS church and they had a years supply of food stored. I don't remember all the details on the why's and how's.

Maybe this can get you started. Google search - Mormon food storage
