Freeze-drying, or lyophilization, preserves perishable materials by freezing and sublimating water through pressure reduction, an ancient process from 13th-century Andean Indians. It advanced in the 1950s. Developed for blood plasma in World War II, it later became common in consumer foods. 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.
Senova, a freeze dryer innovator for 15 years, serves over 80 countries with dependable performance and support, launching an EU office in 2024.
