When you buy bananas, break them apart into individual bananas instead of leaving them in the bunch.

Why YSK: The stem of the bunch is the main culprit for releasing ethylene gas, which is basically a ripening accelerator. By separating them, you significantly slow down this process. This means your bananas will stay yellow and edible for far longer, saving you from having to eat a dozen bananas in two days or, more likely, throwing them out. No more premature browning, unless you’re specifically aiming for banana bread. Your fruit bowl (and wallet) will thank you.

    Who keeps bananas longer than a week? I mean in our household if we buy 10 on Saturday they’ll be one left by the following Friday… 😋

    can you post a picture of what the single banana looks like? how much stem do you leave on each one? nothing? so the tip of the edible fruit is showing?

    I’m curious but kind of skeptical tbh

      Yeah, wouldn’t the increased surface area increase the release of gas making everything ripen faster?

    Put them in the fridge and they’ll last for weeks. They might turn brown after a few days but inside they’ll be fine. Put them in an airtight container and they’ll last even longer in the fridge.

    Or, ya know, you can just wrap some cellophane around the bunch of stems, and wrap that with a rubber band for extra measure.

    Anyways, side note, if you eat a banana (mmm tasty), well mosquitoes will be more attracted to you…

    My girlfriend breaks them apart into singles and then wraps the calyx of each banana (the place where they all were joined…I’m not sure that calyx is the correct word) with aluminum foil. I don’t know if the foil makes any difference though.

      You need to wipe it in honey first, and cover the honey in cinnamon. Then take a toothpick and push it through the center of that. Then, kid you not, chocolate syrup. Put it in the freezer and it’ll last a millennium.

        I can’t tell if you are fucking with me right now. But that sounds delicious so I’m going to try it anyway.

      This OP doesn’t know what they’re talking about. The bananas are picked green, stacked in a warehouse, and then the whole thing is fumigated with ethylene gas. This triggers the ripening process. It doesn’t come from the stem or anything like that (in commercial setting, if left as a bunch on the tree maybe).

        You… must have never bought bananas then?

        The banana still produces ethylene gas, increasing as they get more rip. Regardless of what started the ripening, it doesn’t just stop because you’re no longer pumping gas.

        And OPs tip 100% works.

        So what the fuck are you even talking about lol?

          Have you tested it? Thoroughly? Side by side in controlled conditions? Tell you what, I’ll post my sources. You post yours, and we’ll compare.

          Source one - Ann Reardon tracked down the origin of this myth and put it to test. She’s got an actual degree in food science and makes it approachable for people without a science background. She shows clips of the bulk gassing. I got curious and tested it at home with a similar method to her except I used entire bunches of bananas and gave each bunch their own room to control the process more. I did control for sunlight and temperature as best I could do those were equal across the bunches. The fridge banana was indeed the only one that didn’t ripen at the same time as the rest.

          Source two - a paper discussing how ethylene gas works to trigger ripening and that bananas (and other fruits) are picked green and then gassed with ethylene to control the process. It talks about how this gassing kicks off the process and once it starts there’s no stopping it because the enzymatic processes have begun and enough ethylene gas has already permeated the membrane. It also mentions needing hypobaric conditions to stop mature fruit from speeding up the ripening of immature fruit. Which a fridge although not negative pressure is closer than ambient.

          Source three - External application of ethylene to induce ripening suppresses a bananas internal production of ethylene gas. It’s already producing less than it would on a vine because it doesn’t need to.

          Okay now where’s yours?

          I think we need to buy 4 bunches of bananas from the same grocery store, split two, leave two out but apart. Then record the results
