Space Food & Polyphenols: New Strategies and Applications

Polyphenols have potential applications in the development of space food for astronauts. Here are some ways in which polyphenols can contribute to space food:

Antioxidant Protection: Polyphenols are known for their antioxidant properties, which can help protect cells from oxidative damage caused by radiation exposure in space. Including polyphenol-rich ingredients in space food formulations can provide astronauts with additional antioxidant support to mitigate the effects of radiation.


Nutrient Retention: Space food must be able to retain its nutritional value over extended periods. Polyphenols, with their antioxidant activity, can help preserve the stability of essential nutrients, such as vitamins and minerals, during storage and prolonged space missions. By inhibiting oxidation, polyphenols can contribute to maintaining the nutritional quality of space food.


Immunomodulation: Space travel can have an impact on the immune system, making astronauts more susceptible to infections and illnesses. Polyphenols have been shown to possess immunomodulatory effects, supporting the immune system's function. Incorporating polyphenols into space food formulations may help bolster the immune response of astronauts during their missions.


Psychological Well-being: Long-duration space missions can be mentally challenging for astronauts. Polyphenols have been associated with mood-enhancing effects and may have a positive impact on mental well-being. Including polyphenol-rich ingredients in space food can potentially contribute to psychological support and help mitigate the effects of stress and isolation.


Nutritional Variety and Palatability: Space food often faces challenges in terms of variety and taste. Polyphenol-rich ingredients, such as fruits, vegetables, and herbs, can add flavors, colors, and textures to space food, enhancing sensory appeal and increasing variety. This can help address issues of monotony and enhance the overall palatability of space meals.


Gut Health: Maintaining gut health during space travel is crucial for astronauts' overall well-being and nutrient absorption. Polyphenols have been linked to positive effects on gut health by promoting the growth of beneficial gut bacteria and supporting gut barrier integrity. Including polyphenols in space food can help promote a healthy gut microbiota and ensure optimal nutrient utilization.


If you and your team are working on a project concerning the different applications of Polyphenols in Space Food, you can submit your project to Polyphenols Applications that will support it if selected. For more information about this project and initiative, please contact: projects(at)
