Why does freezing change food texture?
Show answer & explanation
Answer: Ice crystals damage cell walls
Ice crystals damage cell walls ✓ — Correct! When food freezes, water inside cells expands into ice crystals. These sharp crystals puncture cell walls and membranes. Upon thawing, damaged cells leak fluids, making texture mushy (especially in fruits/vegetables with high water content). Flash freezing creates smaller crystals = less damage. Slow freezing = large crystals = mushier texture!
Nutrients crystallize and harden — Wrong. Nutrients don't crystallize significantly. Texture changes from water expanding into ice crystals that physically damage cell structures.
Air pockets form inside food — Wrong. Some air can be incorporated during freezing, but the main texture change is from ice crystals rupturing cells.
