-Freezing is the most cost effective preservation method, due to the [[Environmental conditions|ambient external]] temperature. Food could be stored in containers external to the colony, probably underground, where the temperature is constant during the year at -63 to -68°C over most of Mars' surface.  In most situations, a simple shade would be enough to prevent heating of surfaced stored food even in summer.<br />

-[[Dehydration]] requires a method of removing the moisture from food. It is usually done by heating using hot air.  Smoking is a method of dehydration that also imparts flavors to the food from the combustion of wood chips.  This would be a particluarily luxurious preservation method on Mars.<br />
