This spacefood package contains dehydrated and compressed tuna salad, which was flown on the Apollo 16 mission in April, 1972. As it was not consumed during the mission, it was returned to earth.
Each Apollo crew member was provided with three meals per day which provided approximately 2,800 calories. The food was freeze-dried and was easily reconstituted by the astronaut with a water probe which dispensed one half ounce of hot or cold water as required, each time the trigger button was pressed.
The food was protected with a 4-ply, laminated film coating and had an 8-quinolinol sulfate tablet attached to reduce spoilage in the used food wraps.
Transferred from NASA - Johnson Space Center in 1986.
