About Space Nutrition
Space food are food products, specially created and processed for consumption by astronauts in outer space The food has specific requirements of providing balanced nutrition for the health of individuals working in space, while being easy and safe to store, prepare and consume in the machinery filled low gravity environments of contemporary manned spacecraft In recent years, space food has been used by various nations engaging on space programs as a way to share and show off their cultural activity and facilitate intercultural communication
Today, fruits and vegetables can be safely stored at room temperature are eaten on space flights. Astronauts also have a greater variety of main courses to choose from, and many request personalized menus from lists of available foods including items like fruit salad and spaghetti. Astronauts sometimes request for beef jerkyfor flights, as it is lightweight, nutritious, and can be consumed in orbit without packaging or other changes.
Designing food for consumption in space is difficult. Foods must meet a number of criteria to be considered fit for space; first, the food must be physiologically appropriate, specifically, it must be nutritious, easily digestible, and palatable. Second, the food must be engineered for consumption in a zero gravity environment. As such, the food should be light, well packaged, quick to serve, and easy to clean up (foods that tend to leave crumbs, for example, are ill-suited for space). Finally, foods must require a minimum of energy expenditure throughout their use, i.e., they should store will, open easily, and leave little waste behind.
Carbonated drinks have been tried in space, but are not favored due to changes in belching caused by microgravity; without gravity to separate the liquid and gas in the stomach, burping results in a kind of vomiting called "wet burping".
Foods chosen for the daily menu were selected based on their commonality to everyday eating, the nutritional content and their applicability to use in space. The Daily Menu food supply is based on the use of frozen, refrigerated, and ambient foods. Frozen food includes most entrees, vegetable, and dessert items. Refrigerated food includes fresh and freshtreated fruits and vegetables, extended shelf-life refrigerated foods, and dairy products. Ambient foods include thermostabilized, aseptic-fill, shelf-stable natural form foods, and rehydratable beverages.
Packaging for space food serves the primary purposes of preserving and containing the food. The packaging, however, must also be light-weight, easy to dispose, and useful in the preparation of the food for consumption. The packaging also includes a bar-coded label, which allows for the tracking of an astronaut's diet
