Will Bananas Ripen After Picking?
In a word, yes. All peppers change color as they ripen, but people usually pick banana peppers before this transformation is complete, in the yellow or green stages. Even so, it’s not uncommon to see a banana pepper turn steadily redder if you leave it out in your kitchen for a week or so.
The yellow will give way to a more orange hue that will eventually darken into red. Eventually, they’ll reach a fully red color and it’ll be hard to imagine that they were ever so green. In some cases, they might also take on a bit of a purple color – see below for more information about that.
If you want to, this transformation can be slowed by keeping the banana peppers in the fridge or by freezing them. If you’re going to leave them out, it’s best to check on them every so often to make sure they haven’t started to go bad.
Why Are My Banana Peppers Turning Purple?
You might be shocked to see that your previously green and yellow banana peppers are starting to turn purple. However, you don’t need to worry.
The first thing to understand is that purple banana peppers are still safe to eat and still taste great too. But why are they getting purple streaks in the first place?
There’s an interesting bit of science behind it, actually. In nature, colors like red and purple are natural signals that the plant is mature. The color changes because of chemicals called anthocyanins.
They accumulate near the surface of the pepper and change its color, which means that animals like birds (and people!) are more likely to notice them. It gets even more interesting than that, though.
Fruit-eating insects aren’t attracted to mature peppers because, unlike us, they can’t see red or purple very well. This means that the peppers will be found by animals who can take the seeds far away so the plant can reproduce, rather than by insects who would just eat it where they found it.
As for why the purple streaks sometimes appear and sometimes don’t, it depends on the conditions the peppers are growing in.
If the sun is particularly fierce, for example, the plant can defend itself from its rays by turning a bit purple. There’s nothing abnormal about it and it won’t affect the taste, so bon appetit!
