To produce larger crystals, the product should be frozen slowly or can be cycled up and down in temperature in a process called annealing. The freezing phase is the most critical in the whole freeze-drying process, as the freezing method can impact the speed of reconstitution, duration of freeze-drying cycle, product stability, and appropriate ...

Thus, in the case of a cooking of 25 to 30 minutes in boiling water, peeled potatoes can lose up to 40% of their vitamin C, 10% if they are cooked with the skin (in this last case, there remains 13 mg of vitamin C for 100 g of vegetable). These losses are added to those induced by the storage time, about 50% after three months. [28]
In this case, food is flash frozen and put into a reduced-pressure system which causes the water to sublimate directly from the solid to the gaseous phase. Although freeze-drying is more expensive than traditional dehydration techniques, it also mitigates the change in flavor, texture, and nutritional value .
Dirt protects the potatoes from premature spoiling, and storing moist potatoes could lead to mold Store potatoes in cool but not cold temperatures; between 45°F and 55°F is ideal.
Frozen products do not require any added preservatives because microorganisms do not grow when the temperature of the food is below −9.5 °C (15 °F), which is sufficient on its own in preventing food spoilage. Long-term preservation of food may call for food storage at even lower temperatures.
