Why apples crunch: biophysics of crunch, vacuoles, different varieties. Why does Honeycrisp have a louder crunch?
Biophysics of crunch
Crunch is not just a sound, but part of apple biophysics. Inside the pulp there are thousands of cells that look like small elastic capsules with juice - vacuoles. They fit tightly to each other and are under light internal pressure.
Vacuoles in pulp
When we bite into an apple, many of these capsules burst at once: the vacuoles burst, the juice is released, and the pulp seems to break. This is how the crunch appears.
Varieties and different crunches
Different varieties are constructed differently. Some have larger cells, denser walls and a much louder crunch! For example, the Honeycrisp variety produces a more sonorous and “glassy” apple than most other apples.
