La maduración de la fruta

The video discusses the significance of bananas in global diets and their increasing consumption. It explains how bananas are transported while unripe to prevent damage and how supermarkets use ethene to control ripening. An experiment is conducted to demonstrate ethene's effect on banana ripening, showing that bananas exposed to ethene ripen faster. The video concludes with practical applications of this knowledge in supermarkets.
