When a banana is frozen, the water inside its cells forms ice crystals, which can rupture the cell walls. Once thawed, the damaged cells release enzymes and pigments that lead to browning, primarily due to the oxidation of phenolic compounds. Additionally, the breakdown of cell structure allows for increased exposure to oxygen, accelerating the browning process. This is why thawed bananas often appear brown and mushy.
