The starchy outer layer (peel) of the carrot is harder than the soft central core (also known as the core cylinder). Two carrot halves bend when cut lengthwise because the tension difference becomes unbalanced.
Dehydration further exacerbates this effect by causing the peel to shrink, which pushes the carrot halves together even further.
The researchers say their findings could help food manufacturers reduce food waste by developing more efficient methods for packaging and processing cut carrots. They also hope their work can be applied to other plant structures, such as leaves and stems.
