In order to facilitate preservation and transportation, when picking a banana, you can't wait for it to ripen, but you have to pick it when its skin is green. The bananas we eat in the north are ripened after ripening. The astringency of raw banana comes from the tannin in banana. When banana ripens, although it can't taste astringency, tannin still exists. Tannic acid has a very strong astringent effect. It can form excrement into dry and hard excrement, thus causing constipation.
