Why do carrots turn mushy when cooked?
Show answer & explanation
Answer: Pectin breaks down releasing water
Pectin breaks down releasing water ✓ — Correct! Raw carrots have firm cell walls held together by pectin (a polysaccharide). Cooking breaks down pectin bonds (especially above 80°C), softening cell walls. Water enters cells, making carrots soft and mushy. Longer cooking = more pectin breakdown = mushier texture. That's why raw carrots are crunchy but cooked ones are soft!
Fiber absorbs all moisture — Wrong. Fiber doesn't absorb moisture and cause mushiness. Pectin degradation in cell walls is the cause.
Vitamins leach into water — Wrong. Some vitamins do leach, but texture change is specifically from pectin breakdown weakening cell walls, not vitamin loss.
