Organic bananas are delightful tropical fruits available all year and make a great healthy and nutritious snack.

They are healthy and popular fruits; nevertheless, it is critical to store them correctly to avoid turning black too rapidly.

You may have noticed that bananas at the supermarket are frequently packaged in bunches with plastic wrap wrapped around the stem.

The ethylene gas, in particular, is emitted through the banana stems. 

Organic bananas emit natural ethylene gas as part of the ripening process. The technique to keep them fresh is to wrap the stems with plastic wrap to prevent the emission of ethylene gas. You may accomplish this with a bit of a piece of plastic wrap. Tie a rubber band around the outside of the plastic wrap if it doesn’t stay on tightly.

Why Is a Plastic Used To Wrap Organic Banana Stems?

A large portion of the ethylene emitted by bananas comes from their stems—the more gas produced, the riper the fruit. Ethylene promotes fruit maturation and abscission.

Many climacteric fruits, including apple, banana, and tomato, exhibit a significant rise in ethylene levels at the late green or breaker stage.

Chlorophyll is destroyed as a result of high ethylene levels, and other colors like black are formed. As a result, the ripe banana peel has the usual hue.

Many maturation-related enzymes become more active. Starch, organic acids, and, in rare situations, fats are mobilized and converted to natural sugars.

The plastic wrap aids in the containment of ethylene gas, which bananas naturally emit as they mature.

When the fruit is not wrapped in plastic, the ethylene gas travels to other sections of the banana, causing premature ripening.

Wrapping the stems of organic bananas with plastic wrap helps preserve the freshness and texture of a banana for a longer duration.

It inhibits ethylene from being absorbed into the bananas through the stems, which may be present in the air from other fruits.


Works Best: Ensure that the stems are covered tightly enough to avoid ethylene absorption.


Is It Better to Wrap Organic Bananas as a Bunch or Separate Them?

Wrapping single banana stem vs a bunch

Although wrapping your banana stems in a bunch is a good start, some ethylene may still escape because there are spaces between the stems.

Most bananas on a bunch ripen at somewhat different rates; prematurely ripe bananas will emit more ethylene gas, causing all of the bananas to ripen much faster.

Also, when bananas are linked together, they generate and absorb more ethylene, resulting in browning and overripe bananas.

Keeping them separate and safeguarding their stems assures maximum freshness and that the texture remains as pleasant as the day they became ripe.

The advantage of wrapping the bananas individually is that you don’t have to unwrap the stems when consuming your bananas.

You may open the bananas from the opposite end without removing the stem wrapping and use the wrapped stem as a handle to grasp them.


What We Do: When wrapped as a bunch, every time you remove a banana from the bunch, you must gently wrap it back up so that the bananas may last longer.


Final Thoughts

Bananas that are not wrapped in plastic mature quicker than plastic-wrapped bunches.

Wrapping the top of a bunch of bananas in foil, plastic wrap, or beeswax prevents the ethylene gas that the fruit naturally emits from ripening the banana too soon.

Alternatively, you may need to split apart the bunch before individually wrapping each stem in foil, plastic wrap or bees wrap actually to inhibit the ripening process.

Individually wrapped organic bananas ripen somewhat slower than the whole bunch.

This strategy will not entirely prevent your bananas from ripening, but it will halt the process and likely preserve a lot of them from being thrown away.
