What happens to the texture of overcooked final fries?

When fries are overcooked, they undergo a significant change in texture that leads to being burnt and hollowed out. The excessive cooking time causes the outer layer of the fries to develop a charred, burnt appearance while the inside becomes dry and loses its structural integrity, often resulting in a hollowed-out form. This is primarily due to the breakdown of starches and moisture loss during prolonged exposure to heat, which alters the original intended texture of the fries. In contrast, under or properly cooked fries would retain a lighter, crispier texture or a softer, more palatable feel.
