Bananas with colored spots (plum blossom spots) are easy to peel off.

Banana ripening is divided into seven price segments: ① full green; ② green with little yellow-green; ③ green more than yellow; ④ yellow more than green; ⑤ only fruit stalk and neck green; ⑥ all yellow; ⑦ yellow with brown spots (plum blossom spots).

In the final stage of banana ripening, the pericarp changes from bright yellow to dark yellow, and plum blossom spots appear, which are actually disease spots. Anthracnose, which has been latent invading banana fruit in the field, develops rapidly and shows symptoms when the sugar content increases in the later stage of fruit ripening. At this time, the fruit has completed its respiratory peak and reached full ripening. The aroma of banana fruit is the best and most delicious. At this time, the fiber of the pericarp is also decomposed by respiration, and the pedicel is easily broken at the connection between the stalk and the fruit body.
