Factors for packaging food…
Scientists from NASA have to plan 7,000 meals and snacks for 6 people for up to 3 years!
You lose flavor, nutrients, and texture over time from food in plastic packaging
Foil is too heavy for Mars
22,000 pounds of food at the cost of about a million dollars per pound

3. Food Preservation-methods of storing food so it can be used in the future
Freeze-drying food- removing water from material while still keeping the basic structure and composition of the food. Keeps food from spoiling for a long period of time, and reduces weight of food.
Preservatives-sugar, vinegar, salt, and alcohol delay the spoilage of food.
Exclusion of air- air makes food go bad
An early method of preserving food was partially cooking it, sealing it in a glass bottle with a cork, then putting the bottle in boiling water, like the canning process.
Louis Pasteur came up with pasteurization which was a big progressive step towards food preservation.
Aluminum tubes work pretty well in space.
Astronauts add cold or hot water to freeze dried food or they heat food pouches in an electric warmer
Thermostabilized-killing germs with heat
