Food On The

International Space Station

By Alex & Julian

slide2

How has food for astronauts

changed in the past 50 years?

-The first astronauts ate unappetizing bite sized cubes, freeze dried powders and semi-liquids in aluminum tubes.

-Freeze-dried foods were hard to rehydrate and crumbs had to be prevented from ruining equipment.

slide3

-The astronauts on the Gemini Missions ate slightly better, the first things to go were the tubes, the astronauts ate; bite-sized cubes coated with gelatin to reduce crumbling, and the freeze-dried foods encased in a special plastic container to make rehydrating easier.

-With the plastic packaging came better food quality. Gemini astronauts food choices like the shrimp cocktail, chicken and vegetables, butterscotch pudding, and apple sauce, and were able to meal mix and match themselves

slide4

-The Apollo astronauts were first to have hot water, this made rehydrating foods easier and made food taste better. They were also the first to have the the "spoon bowl," a plastic container that could be opened and eaten with a spoon

Write: banana time

slide5

What foods do astronauts eat today?

-The foods astronauts eat today are; powdered juices, tea, coffee, milk, canned fish, canned eggs and cheeses, canned lamb with vegetables, canned beef with barley sturgeon, canned chicken with rice, dehydrated vegetables, dehydrated pastas, dehydrated potatoes, dehydrated fried rice, dehydrated shrimp, dehydrated soup, MRE’s (Meals Ready to Eat), nuts, dried fruit, breads and assorted sauces

slide6

How are these foods prepared?

-Since some of these foods are dehydrated they have to be rehydrated. They open the bag which contains the dehydrated food and insert water, close the bag and shake the bag to rehydrate the food

-Foods that come in cans are simply warmed up with a can warmer and opened with a can opener.

slide7

How are these foods

kept from spoiling?

-There are three ways they use to preserve the space food:

-Dehydration

-Canning

-Vacuum sealing
