What's the trick to ripening green bananas at home?

Take them out of the plastic bag....like you have in the bowl in your
photo. Or buy nearly ripe bananas.

Black spots on the peel, indicate sugar sweetness. If the peel turns
black, made banana nut bread.

Overripe bananas are great for smoothies too.

Peel and freeze them if too many go bad before you can use them.

My experience with very green bananas.... they often "go bad" before
they ripen.

The ripen process involves the release & the action of ethylene gas.
I typically use a ripe banana to "force ripen" tomatoes.

You can do the same with bananas.
Put the unripe bananas in a brown paper bad along with a ripe apple.
The ethylene gas from the apple will help ripen the bananas.

The paper bag will help concentrate the ethylene gas but not retain
moisture which would encourage the bananas to mold.

I've had a problem with bananas not ripening. Don't know why. Not Costco
bananas though. Those things come loaded with so many fruit flies, I won't
ever buy them again.

The trick is ethylene gas. Given off by (over)ripe fruit.
Put your green bananas in a closed container with other over ripe
fruit.
The ethylene gas given off by the over ripe fruit will ripen your
bananas.

I remember once reading that if bananas are ever ever allowed to go
below 40°F, they will never ripen.

However, this article suggest even higher temperatures than 40°F
can/will permanently stall ripening. See the 'ripening' heading.

I had immediately put a ripe banana and apple in the bags,
leaving one bag as a control.

Here is the current result, after three days:

I'd say, so far, it's a failure; but maybe time will tell.

Can take a lot longer than three days...
Costco doesn't grow bananas, they buy from the same wholesaler that
all the other area stores buy from... the larger stores like Costco
buy in large volume so get the freshest bananas... retail stores
prefer to buy greener bananas... if they ripen too much before they
can sell them they end up in the trash bin. Those plastic banana bags
have large holes punched in them (I can see the holes in your photo),
the ethylene gas produced by the apple and the bananas themselves is
escaping... using those leaky bags is almost like using no bag at all.
Bananas are purposely placed in ventilated bags so that they don't
ripen too quickly, it's difficult to sell overly ripe bananas. The
bananas in the bags with the apple do look slightly riper (more
yellowish) than the bag with no apple all way to the right. If you're
in a big hurry use bags that don't leak... but those bananas will
ripen on their own if left out on the counter with no bag and with no
help at all if you have patience... bananas are harvested very green
so they can survive shipping, you obviously chose the the greenest of
the green, was probably a just arrived shipment. Usually the produce
manager will put the older/riper bananas out first but often in stores
that sell bananas cheap they sell too fast for much in-store ripening.
Btw, most folks complain that bananas ripen too fast, consider
yourself fortunate.

I will switch to clear un-holed plastic bags.

This isn't the first time I've had the Costco bananas not ripen,
but, maybe I just didn't wait long enough.

There was no way NOT to get green bananas, as that's all they
had when I bought them. Must have been a fresh shipment.

If you want to extend the experiment,
keep a bag with holes

& switch to plastic bag w/o holes
but.....
my experience that I shared was with a paper bag (specifically size 8,
oversized lunch bag)

plastic w/o holes may be too mositure tight, rot before ripen?

I'd use a paper bag. Plastic bags tend to allow the fruit to go moldy
long before paper.

Supermarkets have ripening rooms and they control how the banana
reaches the selling floor. Maybe Costco does not do it well.

I buy Costco bananas all the time. It takes a couple days before
they are ripe enough to eat and then every one of them ripens and you
have to eat fast or freeze them. You can keep ripe bananas in the
refrigerator for a couple of days to hold them from spoiling. The
refrigerator will turn the skins black but that doesn't harm the
insides.

I'm not sure, I was told (or read) to use a paper bag...like a lunch
sized bag.

My guess >>>

closed bag is to increase the concentration of ethylene gas, paper bag
to allow bananas to "breath".
Thus preventing rot by not allowing liquid water (condensation) to
accumulate.

Don't know "why" for sure but in my experience paper bags just work.
YMMV

Two comments...


1) Paper bag was suggested (I have never attempted to ripen fruit in
a plastic bag...only paper)
2) Perhaps there is truth to "the less than 40F exposure prevents
ripening" ?
3) Create additoonal condition

Wish I had that problem. I buy three at a time and they ripen very
fast. My market sells Chiquitas by bulk.

I let em sit in an open wooden bowl.

The trick of finding ripe bananas (which isn't what you asked for)
is to look for them in the reduced produce area. God forbid that
unsightly ripe bananas should grace the shelves of normal produce.

Some of the best tasting and ripest fruit comes from the "used food"
cart. I always check it out.

I learned that trick in relatively recent years. I always
wondered where the ripe fruit was.

Grocery stores around here know exactly how much they're selling, so
they know how much to put on the shelves and there's never a "use
fruit" cart.

Sometimes my grocery puts some older bananas in a paper bag in the buggy,
on sale. I grab one every time I see it. That's after they red up the
banana racks.
Then I go buy some jumbo and chipped ham.

The problem was that, at Costco, all they had was green, and greener.
In the past, they NEVER ripened - which is why I asked (they 'must'
be ripening for someone or they'd never be able to sell 'em).

Anyway, here are the four bags of bananas, which were bought two
Sunday's ago, so it has been 10 days to date.

Notice only ONE bag ripened.
http://www4.picturepush.com/photo/a/...g/12582862.jpg

So, I took the liberty of adding a few more inducements to the
bags (leaving the control alone).

I suspect the control will NEVER ripen, and I'll have to throw
it away - but - I'll let the banana prove me right or wrong on
its own.

The point is to figure out HOW to get them to ripen.

I never buy green bananas. The only time I buy bagged bananas, is when they
are by the paper bag full, discounted. Half price or less. Go to a real
grocery.

Maybe you're not to supposed to leave them in the sealed plastic bag
once taken home. Your control group seems to suggest that. The rest
was interesting, with the apples and all.

You're not. Place them in brownpaper bags to ripen.

Well, the funny thing is that, in the past, I've unbagged the green
Costco bananas, and they never ripened. I also left them bagged,
and, they never ripened.

For a long while, I just stopped buying Costco bananas.

But then, I was at Costco on the last Sunday in March, and
I figured I'd buy them, and ASK YOU GUYS.

I do realize the paper bag was the suggested method, along
with the ripened fruits - but I had no paper bags, and not
enough bananas to do all the experiments - so I opted for
the simplest ... which was to put fruits in three of the
four bags.

So far, I've learned that the yellow Dole banana did almost nothing
to ripen the green DelMonte bananas; and I learned that a single
apple was a risk because it appears to depend on the apple.

So I juggled the apples yesterday - and threw away the yellow
Dole which had turned brown all over - and am currently just
waiting to see if the multiple apples will work.

I will report back in a few days...

Dear FC-

imo, your "juggling of the experimental conditions" as time progress
is effectively muddling any results.

You might hit a "home run" and discover a ripening solution but at
this point, I cannot say which of your experimental paths I would
repeat to confirm a success.

That over ripe Dole may have been you best ripening agent. Based on
the results so far, I'd give up on Costco bannanas

UPDATE: 2 weeks later

a. I bought 4 DelMonte banana plastic bags at Costco (Sunday 3/30)
b. I put a ripe apple in two & a yellow banana in one.
c. One of the apple banana bags ripened (and has subsequently been eaten)
d. I added MORE APPLES to the one bag (including the magic apple)
e. I removed the now-wholly-brown ripening banana (which had failed)
f. Now it's exactly two weeks later

Take them out of the bag, sit them on the counter, you can speed up things if you wrap sarran wrap around stump. But the costco bananas are small and even when ripe taste green, guess it's where there from or many other reasons. But seems nobody knows that cavendish bananas are soon to be extinct so a race to save, pick, and transport whats left. Enjoy them while you can because till now no replacement has been found. 😕

Likely they have stopped buying them after 7 years.
