Keeping Nutrients in Astronauts Food Vital During Long Space Flights

18.08.2009
A new study in the Journal of Food Science explores the impact of space flight on the nutritional value of foods. Maintaining the health of the crew aboard a spacecraft is a critical issue especially during extended trips. Because foods may lose their nutrients during extended space missions, food scientists are analyzing ways to increase shelf life of nutrients in the food.

Researchers at the National Aeronautics and Space Administration (NASA) Johnson Space Center in Houston evaluated the stability of fatty acids, amino acids and vitamins in supplements and in foods from a long-duration spaceflight on the International Space Station (ISS).

Tested items included tortillas, almonds and dried apricots, commercially-packed salmon, freeze-dried broccoli au gratin, multivitamins, and vitamin D supplements.

"Destruction of even a single vitamin or nutrient in the space food system could be catastrophic to astronauts in a three-year mission to Mars," said Michele Perchonok, manager of the NASA shuttle food system and member of the Institute of Food Technologists.

Scientists speculated that long-term storage and/or radiation from the space environment could degrade nutrients in foods. Their findings showed:

- The vitamins in the tortillas decreased significantly.

- The vitamins in salmon decreased significantly after 353 days.

- Broccoli au gratin had 15 to 20 percent decreases in folic acid and in vitamins K and C.

- A multivitamin supplement that was used for the study showed that the vitamin A, riboflavin and vitamin C were all decreased after at least 353 days of storage.

- Vitamin D in the supplement declined over time, the longest point in the study was after 880 days of spaceflight.

Researchers are exploring different packaging or other means to increase food shelf life for exploration missions exceeding three years. Researchers are also exploring how the human body's need for nutrients changes during space flight. Both of these have significant implications for future exploration missions.

About IFT

The Institute of Food Technologists (IFT) exists to advance the science of food. Our long-range vision is to ensure a safe and abundant food supply contributing to healthier people everywhere. Founded in 1939, IFT is a nonprofit scientific society with 20,000 individual members working in food science, food technology, and related professions in industry, academia, and government. IFT champions the use of sound science across the food value chain through knowledge sharing, education, and advocacy, encouraging the exchange of information, providing both formal and informal educational opportunities, and furthering the advancement of the profession. IFT has offices in Chicago, Illinois, and Washington, D.C.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
