Survivalists, otherwise known as "doomsday preppers," are having a moment of shine in popular culture. Some people believe that peppers are planning for nuclear warfare, or the world's inevitable economic collapse. Some believe that they are protecting themselves from the upcoming zombie apocalypse. Others believe that these pre-apocalypse preppers and planners are simply and certifiably insane.
Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
