There are many practical difficulties in providing for food storage and
accessibility in spacecraft. The packaging of food materials, both
dehydrated and liquid, has proceeded satisfactorily under the
supervision of the Food and Container Institute. If packaging materials
are to be made to withstand very high relative humidities and large
variations in temperature, additional investigations are required, since
such containers are not yet available. In packaging, serious
consideration must be given to the ease with which the food may be
reached and eaten.
If dehydrated formula foods are to be fed on short-term missions,
additional work is required on the rehydration of such formulas. Present
methods of water measurement under weightless conditions are not
satisfactory, and better methods will have to be contrived.
