There are many aspects of nano- and bio-tech that would assist. Of particular interest to me is the developing ability to grow animal tissue in vats to provide for the human fascination for meat. I think that crews on long term space missions will eat a mostly vegetarian diet because carrying animals for food is resource prohibitive and you simply can't carry enough food for long term journeys.
