To keep bananas green longer, the most effective method, according to the reference provided, is to wrap the stems in plastic.
The Best Method: Wrapping the Stems
Based on the information from Allrecipes, the primary strategy to slow down banana ripening and keep them green is to create a barrier around the stems.
Why Wrapping Stems Works
- Ethylene Gas Production: Banana stems are the main producers of ethylene gas. This natural plant hormone is responsible for ripening fruit, including the bananas themselves and any other fruits placed nearby.
- Containing the Gas: By wrapping the stems tightly in plastic wrap, you effectively contain the ethylene gas. This prevents it from reaching the rest of the banana and significantly slows down the ripening process.
- Extending Freshness: Limiting the exposure of the banana fruit to the ethylene gas produced by its own stem helps to extend its longevity and keep it in a greener state for a longer period.
This simple technique acts as a barrier to the ripening agent, helping you preserve your bananas for longer.
