We produce in our state-of-the-art facility via employing a unique and innovative technology which is called freeze-drying. Fundamental principles in freeze-drying comes from the sublimation process. Sublimation is a phase transition process from a solid to a gas without ever entering an intermediate liquid phase.
In our freeze dryers, moisture is removed from the product up to 98% under low vacuum and low temperature. Vacuum environment that is created by our freeze dryers to lower the air pressure in their chambers and initiates the phase change of water from ice crystals to gaseous without melting which has a significant impact to prevent the mushy and shrivelled appearance in finished products. That is why freeze-dried products still looks like a fresh product, instead of a mushy shape.
Since vacuum makes sublimation possible under low temperature, freeze-dried products preserve its shape, aroma, flavour, colour, vitamin retention and nutrient content. Thus, freeze-drying is known as the best drying technique for heat-sensitive foods.
Freeze-dried foods can last up to 20 years in the proper packaging and storage condition due to their low moisture (2-3%) content without any additives or preservatives.
Unchanged cell structure make them ready to take on water again. Freeze-dried products may rehydrate in a couple minutes and they can be used as a ready-to-eat meals.
Freeze-drying removes about 97% of a food’s water content and so the weight of that food is reduced by as much as 90%. Light freeze-dried foods are very handy and convenient for traveling and long-haul endurance events.
As they have crispier texture, they are strong alternative to unhealthy crunchy snacks. Moreover, this texture increases the fruit and vegetable consumption for kids.
Freeze-drying is also knowns as lyophilisation which was invented in 1906. In the early stages, it was implemented to preserve blood serum due to ability of preserving of heat-sensitive biological materials.
In the mid-1900s, beside pharmaceutical industry, it was started to use for foods. Freeze-dried foods became a major meal for astronauts and military rations.
Currently, freeze-dried foods used for instant coffees, cereals, granolas, instant soups, ready to eat meals, natural food flavouring and colouring, backpacking meals, pet foods and standalone snacks.
