Adding bread to advanced life support systems (ALSS) for space missions is feasible. Bread made from controlled environment-grown wheat received high sensory acceptance and contained more minerals than conventional flour.

Area of Science:

  • Astrobiology
  • Food Science
  • Biotechnology

Background:

  • Biologically based Advanced Life Support Systems (ALSS) are crucial for long-duration space missions.
  • Plant-based food systems offer a sustainable alternative to traditional resupply methods.
  • Integrating diverse food processing, like baking, is essential for comprehensive ALSS.

Purpose of the Study:

  • To evaluate the feasibility and acceptability of incorporating bread into an ALSS.
  • To characterize the production of bread from wheat grown in controlled environments.
  • To compare the nutritional profile and sensory qualities of space-grown wheat bread with conventional bread.

Main Methods:

  • Cultivation of wheat in a controlled environment simulating space conditions.

  • Milling of controlled environment-grown wheat into flour.
  • Baking bread using the processed flour.
  • Sensory analysis of the baked bread.
  • Chemical analysis of flour for mineral content and volatiles during baking.

    • Main Results:

    • Bread baked from controlled environment-grown wheat demonstrated high acceptability in sensory tests.
    • Flour from controlled environment-grown wheat exhibited higher concentrations of potassium, sodium, iron, and phosphorus compared to commercial flour.
    • Key volatile compounds identified during bread rising and baking included ethanol and acetaldehyde.

    Conclusions:

    • Bread production is a viable component of plant-based ALSS for space exploration.
    • Controlled environment agriculture can yield wheat suitable for producing palatable and potentially more nutritious bread.
    • Further research should explore the impact of volatiles and optimize nutritional content for space missions.
