Space Miso Magic: A Leap for Space Cuisine and Astronaut Nutrition
Forget those lackluster space meals that consist of freeze-dried ice cream or mashed potatoes. Space travelers aboard the International Space Station (ISS) have now demonstrated the ability to prepare mouth-watering fermented delicacies like the Japanese soybean paste, miso, in space.
To those who aren't frequent ISS residents, this news might seem trivial. However, it could hold some significant implications for future, more ambitious space missions. Planning such voyages, including potential Mars trips, hinges on finding solutions for astronauts' sustenance over extended periods. The ability to ferment their own ingredients could not only contribute to their nutrition, but could also lift their spirits with tasty, comforting meals.
This culinary breakthrough began in March 2020, when an international team of food scientists sent a package containing a mixture of soybeans, rice koji (a type of mold), and salt to the ISS. Their mission was to see if the mixture would ferment, producing the delectable miso paste.
Miso was chosen thanks to its diversity of microbial communities, its firm structure to prevent leaks in the ISS's sensitive environment, and its strong, nutritious profile. After 30 days aboard the ISS, the miso was shipped back to Earth for analysis.
While space's unique conditions could have interfered with the fermentation process, the miso turned out to be a success. The only differences observed when compared to Earth-made miso were variations in the ratio of different microbes, still identifiable as miso. Researchers attributed these changes to the space environment's effects on microbial growth and fermentation.
"The space environment in low Earth orbit-particularly microgravity and increased radiation-can influence microbial behavior and fermentation," said Joshua D. Evans, senior researcher at the Technical University of Denmark's Novo Nordisk Foundation Center for Biosustainability. "We wanted to investigate these impacts."
This space miso served up more than just its characteristic umami flavor-it could also be a game-changer for future space missions. In recent years, produce such as lettuce has been grown and consumed aboard the ISS. NASA has even turned food technology development into a competition. As missions to Mars and beyond inch closer to feasibility, figuring out how to keep astronauts fed without turning their spacecraft into a pantry remains a crucial hurdle.
This small batch of nutty, space-made miso could go a long way-both in nutritional value and morale-boosting flavor.
Enrichment Data:
The ability to ferment food in space, as demonstrated by the successful fermentation of miso on the International Space Station (ISS), could offer benefits for astronauts' nutrition, morale, and mental well-being. Here are potential positive impacts:
Astronaut Nutrition and Well-being:1. Fermented foods provide essential nutrients, vitamins, minerals, and probiotics.2. Strong-flavored fermented foods like miso can help combat the dulling of taste perception in space.
Psychological and Cultural Aspects:1. Fermented foods can create a connection to Earthly traditions and cultures, boosting morale and a sense of belonging among astronauts on long missions.2. Offering a variety of foods representing diverse human experiences can contribute to astronauts' well-being and satisfaction with their diet.
Technological and Logistical Advantages:1. Fermentation is a natural method of food preservation, helping to reduce reliance on resource-intensive technologies for food preservation and transportation in space.2. In-space fermentation could support in-situ food production, reducing the need for Earth-transported food and contributing to sustainability during long-duration missions.
Further research is needed to understand the effects of microgravity and radiation on fermentation processes, and to develop scalable and replicable fermentation methods for different space environments.
- The successful fermentation of miso on the International Space Station (ISS) could offer astronauts beneficial nutrients, vitamins, minerals, and probiotics for their well-being.
- By fermenting their own food in space, astronauts can create a connection to Earthly traditions and cultures, boosting morale and a sense of belonging during long missions.
- In-space fermentation for food production could support sustainability during long-duration missions and reduce the need for Earth-transported food, thanks to its natural method of food preservation.
- The technological and logistical advantages of learning more about fermentation processes in microgravity and radiation could help develop scalable and replicable fermentation methods for various space environments, contributing to future space cuisine and astronaut nutrition.
