Freeze-drying, or lyophilization, preserves perishable items by freezing and sublimating water through pressure reduction, an ancient practice from 13th-century Andean Indians. It refined in the 1950s. Developed for blood plasma in World War II, it later entered consumer food markets. Albert Altmann freeze-dried organ pieces in 1890; 1920s patents included rabies virus freeze-drying. The 1950s saw camping food applications. NASA adopted it for space food, notably freeze-dried ice cream on Apollo 7 and Gemini. Nestlé’s 1965 instant coffee made it mainstream. Early applications by Aztecs and Eskimos involved biological sample preservation. Contemporary freeze-drying freezes products in specialized chambers with heaters to form solid granules determined by chamber design.
Advantages: foods last 7–8 times longer than fresh, retain nutrients, save money, and are convenient. Freeze-dried foods are nutritious, and dairy preserves probiotics.
