Freeze-drying (lyophilization) preserves perishable items by freezing and sublimating water under low pressure, an ancient method tracing to 13th-century Andean Indians. It evolved into a refined technology in the 1950s. Initially developed for blood plasma in World War II, it later spread to consumer foods. Key historical figures include Albert Altmann, who freeze-dried organs in 1890, and Vansteenberghe and d’Arsonval, who patented rabies virus freeze-drying in the 1920s. The 1950s saw camping food applications, and NASA adopted it for astronaut meals, with iconic freeze-dried ice cream on space missions. Nestlé’s 1965 instant coffee launch made it mainstream. Historically, Aztecs and Eskimos used similar techniques for biological samples. Modern processes involve freezing in specialized chambers with heaters to form granules based on chamber design.

Benefits include extended shelf life (7–8 times longer than fresh), nutritional retention, and convenience. Freeze-dried foods are nutritious, economical, and preserve dairy probiotics.
