Freeze drying was developed during World War II as a way to keep medication for the wounded from spoiling due to uncertain refrigeration while being transported to war zones. The technology was refined and used extensively during the NASA space program, providing varieties of freeze dried food for astronauts.One
Freeze drying (lyophilization) is a dehydration technique where a product is dried under vacuum at low temperature. The water that is contained in the sample is thereby frozen to a solid (ice) and then removed by turning the ice into vapour. Conducting this process under vacuum allows the water to
Freeze dried foods have become so popular that you might have seen them at your grocery store. This type of food preservation is steadily gaining popularity because you do not have to add any preservatives yet you can safely store food for many years without damaging its nutritional structure
Instant coffee, also calledsoluble coffee, coffee crystals, and coffee powder, is a beverage derived from brewed coffee beans that enables people to quickly prepare hot coffee by adding hot water or milk to the powder or crystals and stirring. Instant coffee is commercially prepared by either freeze-drying or spray drying, after which it can be rehydrated.
what is freeze drying? Freeze drying is the process of dehydrating frozen foods under a vacuum so the moisture content changes directly from a solid to a gaseous form without having to undergo the intermediate liquid state through sublimation. In this process, freeze dried food maintains its original

Freeze-dried ice cream is ice cream that has had most of the water removed from it by a freeze-drying process, sealed in a pouch, and requires no refrigeration. It is also known as astronaut ice cream or space ice cream, typically a slab of ready-to-eat dehydrated ice cream. Compared to regular ice cream, it can be kept at
Freeze-dried meats are a great way to add protein to your food storage pantry. Freeze-dried foods maintain all of their same nutritional value and taste. Protein-rich foods like freeze dried chicken, freeze dried ground beef, freeze dried pork chops, and even freeze dried bacon, should be a staple in
Freeze drying has been used in a number of applications for many years, most commonly in the food and pharmaceutical industries. There are, however, many other uses for the process including heat-sensitive sample preparation, plant material research, the stabilization of living materials such as microbial cultures, long term storage
What is an Lyophilization? Lyophilization, also known as freeze-drying, is a process used for preserving biological material by removing the water from the sample, which involves first freezing the sample and then drying it, under a vacuum, at very low temperatures. Lyophilized samples may be stored much longer than untreated samples.
The freeze-drying process offers the flexibility to remove moisture content and preserve almost any fruit or vegetable. Take a look at our products, and you can see the variety – everything from apples to zucchini. But apart from sheer variety, the major advantage of freeze-drying lies in the ability to
Trying to keep biological samples extremely cold—say, –50 to –80° Celsius—takes an ultralow-temperature (ULT) freezer. As we know, ultra-low temperature (ULT) freezers are specifically made to work between -86°C and -45°C, but they often work at a set temperature of -70°C or -80°C. These freezers can last for about 12 to
Autoclaving is the most effective and reliable means of sterilizing laboratory materials. Autoclaving sterilizes material using saturated steam under pressure (“moist heat”). Due to the use of pressure, steam and high temperatures, there is significant risk for injury, so it's important for individuals to be properly trained on operational
When you hear the word “freeze-dried” you might think of astronaut food – those dehydrated meals that don’t look or taste like the food they are named after. In reality, freeze-dried cat food is actually one of the healthiest options on the market. Rather than going through the process
Fruits are delicious and sweetened with natural sugars, which make them not only delicious but also nutritious. Nutrients like vitamins, fiber and minerals can be found in them. They also have low-calorie content. No wonder they are considered to be nature's healthy candy. Freeze-drying techniques are a bit more
Freeze drying or lyophilization is applied to pharmaceutical research, development, manufacturing, and transport. Lyophilization in the development of biopharmaceuticals revolves around the process of sublimination, by which proteins, antibodies, or other drug and drug-related substances are converted from a solid phase directly to a gaseous phase. Freeze drying is
