    What makes bananas ripen?

    Bananas ripen from green to yellow, then brown. The color change is caused by a chemical reaction that changes the banana’s starch into sugar and other compounds. This process takes about three weeks. When bananas are ripe enough for eating, they have a soft texture and sweet flavor.

    The ripening process begins when ethylene gas (a natural plant hormone) enters the fruit through its skin. Ethylene triggers enzymes that convert starches into sugars. As the bananas ripen, they produce more ethylene gas, which causes additional ripening.

    The next step is that the banana starts to soften. When you bite into a ripe banana, you can feel its softness. It’s not mushy or squishy like raw potatoes. Instead, it feels firm but springy. That’s because the cell walls have softened.

    When bananas are fully ripe, they will be very sweet. You may even notice a slight aroma coming from the fruit. As the banana ripens, starch turns into sugar. Once the banana has reached full maturity, it will no longer produce any more starch.

    How Do You Tell If A Banana Is Ripe?

    The best way to tell if a banana is ready to eat is to smell it. If it smells like your bananas; put them up against your nose so you can get a good whiff.

    Ripe bananas are also yellow, and they may have soft spots on the skin. The more ripe the banana, the softer these spots will be.

    If you don’t want to use your sense of smell, then look at the banana. When it’s fully ripe, there should be no green left on the peel.

    You can also check for ripeness by feeling the skin. It should feel spongy or mushy.

    When To Eat Your Bananas

    You can eat any banana once it has turned yellow and softened. But you shouldn’t eat a banana before it turns yellow. That’s because the enzyme that converts starches into sugars isn’t active until the banana starts to turn yellow.

    So, if you’re going to eat a banana, wait until it’s fully yellow.

    If you’re buying bananas at the grocery store, check the date on the sticker. You want to buy bananas that are at least two or three days old. That way, they’ve had time to ripen naturally. Store-bought bananas may be picked too early, so they won’t ripen properly.

    How to ripen bananas faster 

    To speed up ripening, put the bananas in a kraft paper bag and leave it on your kitchen counter. To ripen bananas even faster, add an apple to the bag. 

    How Long Does A Banana Last After Ripening?

    Bananas keep well stored in a cool place with low humidity. Their shelf life depends on several factors:

    • How ripe the banana was when you bought it
    • Whether or not it has been refrigerated
    • Whether or not it had any bruises

    Where you buy your bananas also matters. If they’re from an organic farm or a local farmer’s market, then they will be ripe when you get them. But if you buy them at a grocery store, they may have been picked too early and are still green. That means will take longer to ripen. If you do decide to eat one that is still green, just peel off the skin and enjoy! Green bananas are delicious and nutritious. They contain more potassium than other fruits. However, they are not as tasty as ripe ones.

    Also throw them out if they smell or look unusual, or if mold appears.
