Bananas tend to ripen faster than many other fruits because they naturally produce ethylene gas, a plant hormone that speeds up ripening. When they are stored near other ethylene-producing fruits like apples, pears, or avocados, the process becomes even quicker.
As bananas ripen, their starches gradually turn into natural sugars, which makes them softer and sweeter. At the same time, exposure to oxygen triggers enzymatic reactions that cause the peel to develop brown spots and darken over time. Heat, bruising, and lack of airflow can also speed up this process significantly.
To help bananas last longer, it’s best to keep them separated from other fruits, store them in a cool and well-ventilated place, and avoid sealing them in plastic bags or airtight containers. These small changes can slow down ripening and preserve freshness for a longer time. 🍌
