Processing of nutritious, safe and acceptable foods from CELSS candidate crops.
A controlled ecological life-support system (CELSS) is required to sustain life for long-duration space missions.  The challenge is preparing a wide variety of tasty, familiar, and nutritious foods from CELSS candidate crops under space environmental conditions.  Conventional food processing technologies will have to be modified to adapt to the space environment.  Extrusion is one of the processes being examined as a means of converting raw plant biomass into familiar foods.  A nutrition-improved pasta has been developed using cowpea as a replacement for a portion of the durum semolina.  A freeze-drying system that simulates the space conditions has also been developed.  Other technologies that would fulfill the requirements of a CELSS will also be addressed.
