Bananas are prolific producers of ethylene, a gaseous plant hormone that triggers the ripening process in climacteric fruits such as apples, avocados, and peaches. This gas diffuses into the surrounding air, causing nearby produce to convert starches to sugars, which results in softening and sweetening.

Because bananas continue to ripen after harvest, they often undergo rapid ripening that leads to dark skin and a soft texture. To manage this process and slow ripening, techniques include wrapping the stem or crown of the banana bunch in plastic wrap or aluminum foil to contain the ethylene gas. Experts suggest that this specific technique can extend the fruit’s freshness by four to five days.

Other methods to preserve fruit quality include using banana hangers or hooks to improve air circulation and mimic the fruit’s natural position on a tree. Additionally, avoiding stacking fruit helps prevent bruising and internal oxidation.
