7 Mind-Blowing Facts About Freeze Drying That Will Astound You

Freeze-dried is a process of preservation that entails the removal of water from a substance through sublimation, while maintaining its structural integrity and chemical composition. This technique combines two fundamental scientific principles: freezing and dehydration. First, the material to be freeze-dried is subjected to extremely low temperatures, causing the water within it to solidify into ice crystals. Subsequently, a controlled reduction in pressure is employed, facilitating the direct […]
