Food products subjected to sublimation-based dehydration techniques are progressively gaining recognition within the culinary industry, attracting an expanding base of advocates. Fruits that retain both their visual appeal and original structural integrity through this process have become a staple in the artistic culinary presentations of dietary influencers across the globe. Nevertheless, legitimate inquiries persist regarding their genuine nutritional composition and the process’s impact on bioactive compounds. This comprehensive article elucidates the fundamental principles of lyophilization, delineates its operational mechanisms, and explores its practical applications in contemporary food manufacturing.
Liofiliation
Liophilization is a process that combines the findings of the sciences of chemistry, biology, physics and biochemistry. It was first used in the 1950s. It involves removing water from food in a way that preserves almost perfectly the chemical, biological and physical properties of natural raw materials. In other words, it is the drying of frozen material using reduced pressure by sublimation of ice.
Freeze-dried food
Freeze-dried food, because it contains very little water in its composition, is very durable. It can be stored for a long time. In addition, it is highly attractive because it maintains the fragile and stable structure of natural raw materials, as well as the stability of color and volume.
Fruit freeze-dried
Freeze-dried fruits are valued not only for their attractive appearance, consistency and texture, but above all for their composition. It's no secret that the best seasonal fruits are harvested when they're at their best. These frozen ones have a slightly deteriorated nutritional value, but are far better than those grown wholesale in greenhouses.
