WHAT IS LYOPHILIZATION? (Lyophilizer FREEZE DRYER)
Lyophilization is a drying method applied to foods that consists of removing water. Unlike other methods, the removal of this water is not done by evaporation, but by fast freezing the water and then sublimating it in an atmosphere of low pressure and controlled temperature.Lyophilization is a process of dehydration of samples (Freeze Drying) that are frozen at a very low temperature and then submitted to a vacuum environment that sublimates all their water, without damaging their fibers, and preserving all their nutritional characteristics and organoleptic (texture, taste, smell and color).
In the industrial scope, lyophilization has as its principle the freezing of the product at -60°C and the subsequent sublimation of the water present in the food. These conditions allow nutrients that are not heat resistant, such as proteins and sensitive micronutrients (vitamins), to be protected from enzymatic and oxidative reactions that lead to nutritional losses.
Another positive point is the possibility of the lyophilized product being stored at room temperature and having its weight and volume reduced, resulting in a reduction in packaging costs, increased shelf life, storage and transport. In addition, there is its efficiency in dehydrating raw or cooked beef, seafood, fruits and vegetables.
WHAT ABOUT THE BENEFITS OF LYOPHILIZATION?
Regarding this drying process, we can highlight the high cost of lyophilization compared to other drying methods. Furthermore, the dehydration speed is slow and requires a high energy consumption, which makes it unfeasible for different situations and products.
Among The Advantages Of Lyophilization We Can Highlight:
• Nutritive and sensory characteristics of the final product are similar to fresh food
• Low loss of nutrients and volatile compounds
• Provides a greater ability to rehydrate the powder and consequently promoting a longer shelf life of the product
AND WHICH EQUIPMENT IS RESPONSIBLE FOR THE PROCESS?
The lyophilizer or freeze dryeris an instrument that allows separating traces of water or solutions from solutions of various products. It also advises other processes such as lyophilization tests. Used not only in the food industry, but also in the pharmaceutical and technological industry, the Lyophilized comprises the equipment used in this drying process.
