Who invented freeze-drying food?

Freeze-drying was invented by

Jacques-Arsene d’Arsonval

at the College de France in Paris in 1906. Later, during World War II, it was widely implemented to preserve blood serum. Since then freeze-drying has become one of the most important processes for preservation of heat-sensitive biological materials.

Who invented NASA freeze-dried ice cream?

Compared to regular ice cream, it can be kept at room temperature without melting and is more brittle and rigid but still soft when bitten into. It was developed by

Whirlpool Corporation

under contract to NASA for the Apollo missions.

How was freeze-dried food invented?

Freeze drying

Freeze-drying was first discovered by

the Incas

, who noticed that food stored at high altitudes would freeze and then dehydrate over time. The process was refined during World War II when it was used to preserve blood products and medicine, but it was NASA that turned the process into an art form.

relatively high survival after freeze-

drying. Motile genera with peritrichous flagella showed low survival rates after freeze-drying.
