Sweet potato enhances space diets by providing essential nutrients like beta-carotene. Incorporating sweet potato recipes into vegetarian menus significantly boosts nutritional value and dietary options for astronauts.

Area of Science:

  • Space exploration
  • Nutritional science
  • Food technology

Background:

  • Sweet potato is a key crop for NASA's Advanced Life Support Program.
  • It offers carbohydrates, beta-carotene, and ascorbic acid vital for space diets.
  • Tuskegee University developed vegetarian sweet potato recipes for space food applications.

Purpose of the Study:

  • To evaluate the nutritional impact of incorporating sweet potato recipes into a vegetarian space menu.
  • To assess the feasibility and benefits of using sweet potato products in space missions.
  • To enhance the dietary variety and nutrient content of astronaut meals.

Main Methods:

  • Formulation and sensory evaluation of 10 vegetarian sweet potato products (6-20% dry weight).
  • Substitution of these recipes into a 10-day vegetarian menu plan from the American Institute of Biological Sciences (AIBS).

  • Nutritional analysis comparing the modified AIBS menu with the original, focusing on key nutrients and calories.

    • Main Results:

    • The modified menu showed significantly improved beta-carotene content (p<0.05).
    • Other nutrients and calories were comparable or higher than the original AIBS menu and NASA's Controlled Ecological Life Support Systems Recommended Dietary Allowance (RDA).
    • Sweet potato products were found to be acceptable and suitable for inclusion in space menus.

    Conclusions:

    • Sweet potato-based recipes can be successfully integrated into space menus.
    • These products offer increased nutritional value, particularly in beta-carotene.
    • Sweet potato contributes to dietary variety, supporting long-duration space missions.
