: Unique among most substances, water expands when it freezes, which can lead to practical issues like frozen and burst water pipes . 2. Freeze-Drying Technology
: While freeze-drying extends shelf life by lowering water activity to below 0.85, it does not kill bacteria ; microorganisms simply go dormant and can reactivate if moisture is added back. 3. Food Preservation & Storage Freeze
