This spacefood package contains compressed fruitcake cubes, which were flown on the Apollo 11 mission in July 1969. These cubes were eaten without the addition of water and were "bite-sized" to minimize the possibility of crumbs.
Each Apollo crew member was provided with three meals per day which provided approximately 2,800 daily 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. This protected the food from loss of flavor, moisture and oxygen invasion, spoiling and excess crumbling, and was used on both the rehydratable and the bite-sized foods. The rehydratable foods also had an 8-quinolinol sulfate tablet attached to reduce spoilage in the used food wrap.
NASA transferred this to the Museum in 1986.
