I’m not sure if that’s true as afaik bananas release some sort of heavier than air gas that causes both themselves and lots of other produce to ripen faster. The more airflow the less banana gas.
Just like me trying to avoid sweeteners for decades now because I suspect they might turn out to be bad for you (and noone has ever tried to suggest they are actively good for you…) If it turns out you’re wrong, you’ve lost very little, if it turns out you’re right then there’s no way to retroactively undo the harm.
I have a fairly sensitive sense of taste and if I eat an unwashed fruit with a rind and manage to touch the actual fruit without washing my hands after touching the rind, I can often taste a bitter chemical flavour that otherwise isn’t there. How harmful those chemicals may be and how exposed I’d be without directly transfering them to the food or to my mouth (or eyes or whatever) I’m unsure (and, tbh, while I always wash oranges and stuff, I often eat bananas unwashed as there’s no need for the outside to come into direct or indirect contact with the actual fruit itself.) I’d still prefer to just not eat whatever it is if I can trivially avoid it (both for possible safety reasons and just not having my food taste like bitter chemicals reasons.)
Have you ever had the chance to try plantains? They’re a bit like bananas but for cooking and while they can be used yellow, generally they are used green.
I wonder if they might actually be combining them from different deliveries. IE, they grab an average ripeness one from the Monday delivery, an average ripeness one from the Tuesday delivery etc and by the time the last delivery is added the first one is about ready to eat.
Yeah they’re only ever really used cooked. (I gather that they aren’t nearly as nice to eat raw and might make your stomach a bit upset if eaten raw but possibly are not actively bad for you like eating a raw potato is.) Cooked they’re pretty nice. Kinda like if a banana thought it was a potato.
In South Korea, some stores carry "one a day" bananas which are packaged in order of ripeness (lemmy.world)
