I remember reading in a Shadowrun source book, i think it was second ed Shadowtech, about mycoprotine. Synthetic meat. I would imagine by TL 13 or 14 that it would be rather easy to synthatize, even onboard a ship. that could cut down on storage for food. and at higher tech levels it should be able to be portable...thus could be a major asset to survival equipment, and lenthen the amount of time some one could live in emergency situations. I think the stuff can be injected with various flavours too, so its not jsut a bland material.
