“…Nitrogen flow in a bioregenerative life-support system has been studied by Loader et al [5] by using a simple mass balance to investigate the effect of nitrogen leakage on the overall system supply requirements. Finn [6] performed a steady-state mass balance calculation for "Bioregenerative Planetary Life-Support Systems Test Complex" [7] to investigate design issues regarding storage and/or processing of solid wastes. McGlothlin et al [8] carried out mass balance calculations for the water recovery and air-revitalization systems and developed a sizing tool useful for the conceptual design of lifesupport systems.…”

“…The National Aeronautics and Space Administration's Johnson Space Center (NASA‐JSC) is designing and building a habitat (BIO‐Plex) intended for evaluating advanced life support systems developed for long‐duration missions to the Moon or Mars where most of the consumables will be recycled and reused (1). A food system based on raw products obtained from higher plants (such as soybeans, rice, wheat, potato, peanut, and sweet potato) may be an important feature of a bioregenerative Advanced Life Support System (ALSS).…”

NASA-Johnson Space Center is designing and building a habitat (Bioregenerative Planetary Life Support Systems Test Complex, BIO-Plex) intended for evaluating advanced life support systems developed for long-duration missions to the Moon or Mars where all consumables will be recycled and reused. A food system based on raw products obtained from higher plants (such as soybeans, rice, and wheat) may be a central feature of a biologically based Advanced Life Support System. To convert raw crops to edible ingredients or food items, multipurpose processing equipment such as an extruder is ideal. Volatile compounds evolved during the manufacturing of these food products may accumulate and reach toxic levels. Additionally, off-odors often dissipated in open-air environments without consequence may cause significant discomfort in the BIO-Plex. Rice and defatted soy flours were adjusted to 16% moisture, and triplicate samples were extruded using a tabletop single-screw extruder. The extrudate was collected in specially designed Tedlar bags from which air samples could be extracted. The samples were analyzed by GC-MS with special emphasis on compounds with Spacecraft Maximum Allowable Concentrations (SMACs). Results showed a combination of alcohols, aldehydes, ketones, and carbonyl compounds in the different flours. Each compound and its SMAC value, as well as its impact on the air revitalization system, was discussed.
