What Causes Bananas to Ripen? | LEAFtv

Enzymes break down chlorophyll molecules that make the banana peel green. The green pigment of chlorophyll is destroyed, and the result is either the golden yellow color bananas are known for, or shades of red or purple for other banana varieties. An enzyme called amylase breaks down the starch in the fruit into its smaller sugar components ...
