An ancient preservation process, freeze-drying (lyophilization) enhances portability by freezing materials and sublimating water via pressure reduction. It began with 13th-century Andean Indians and advanced in the 1950s. World War II saw its first application for blood plasma. Post-war, it became common in consumer foods. Albert Altmann freeze-dried organs in 1890; 1920s patents covered rabies virus freeze-drying. The 1950s introduced camping food uses. NASA employed it for astronaut food, famously with freeze-dried ice cream on space missions. Nestlé’s 1965 freeze-dried instant coffee mainstreamed it. Historically, Aztecs and Eskimos used similar techniques for biological samples. Modern processes freeze products in designed chambers with heating to create solid granules based on chamber speed and geometry.

Benefits include extended shelf life (7–8 times longer than fresh), nutritional preservation, cost savings, and convenience. Freeze-dried foods are nutritious, and dairy retains probiotics.

Senova freeze dryers, used globally in homes, labs, and industries for 15 years, provide reliable support across 80+ countries, with an EU office in 2024.
