Have you ever pulled a bok choy out of your fridge, inspected it, and found that it has brown spots on the sides? What does this mean? Is it still safe to eat?
If your bok choy is still firm, fresh, and has bright green leaves, it should be fine to eat. Brown or black spots on the ribs are known as “pepper spot” and are perfectly safe to consume. However, brown spots appearing will often be a sign that the vegetable is past its best, and you should inspect it for other signs of decay.
In this article, we’ll find out more about how bok choy should look, and how to tell if your bok choy has gone off.
Are Brown Spots On Bok Choy A Bad Sign?

In many cases, brown spots on bok choy are a sign that the vegetable is decaying, yes. Firstly, let’s deal with pepper spot. This is a harmless, cosmetic condition that will cause small brown spots to appear on the ribs of the vegetable. These will be there even when the bok choy is very fresh, and they are perfectly fine to eat.
However, in many cases, brown spots are the result of decay, and that means you should be inspecting your bok choy more closely. Sometimes, it will still be okay to eat as long as you use it up quickly, but in other cases, it will be past its best and will need to be thrown away.
There are a few key things to look out for, and these include:
- Are the leaves green?
- Are the stalks firm?
- Does the vegetable taste okay?
- Does the vegetable smell okay?
Let’s look at how you can test for each of these in more detail.
Are The Leaves Green?
Wilted, yellowing leaves or leaves that feel damp and limp indicate that your bok choy has gone off. If you see brown spots on the stems, get them out and inspect the foliage closely. You should easily be able to tell if it’s going off because the leaves will be floppy.
This happens because the water has gone out of them, and they are starting to shrivel up. If you leave the vegetable for longer, they will either shrink into almost nothing or begin to rot and turn slimy.
If only one or two leaves have gone limp, you may be able to remove these and use the rest, but it will need to be used up quickly.
Are The Stalks Firm?
Next, check the stalks of your bok choy. They should feel firm under your fingers, and have little give if you press on them.
Rubbery stalks that bend if they are put under pressure, rather than snapping, are very likely to have started to go off. Again, the lack of water in the plant’s tissues is reducing the pressure on the cells, and this means that they can bend rather than breaking.
If you aren’t sure, remove a stalk from the bok choy and gently bend it. If it snaps, the vegetable is still fresh, but if it bends and squashes under your fingers, you may need to throw it away.
If any parts of the stalk have turned mushy or have visible mold growing on them, throw the vegetable away.
Does The Vegetable Taste Okay?
Tasting bok choy is another great way to test whether it’s still safe to eat. If you can see brown spots on the stem but the vegetable still looks okay, cut off a small piece of a leaf, wash it, and taste it. It’s safe to eat raw, and this can be a good way to test if it’s still okay.
If the leaf tastes like spinach, it should be fine to consume. However, if you can taste bitterness or a musty flavor, you will need to throw it out.
Does The Vegetable Smell Okay?
This test can be harder to use because bok choy doesn’t have much of a smell, but it’s still worth trying it. Let the vegetable warm up to room temperature, and then rub a hand over the leaves and smell them. If you can smell a vaguely plant-like aroma but not very much, your bok choy is probably still safe to eat.
If you can smell anything sour, sweet, or sharp, the bok choy has probably started to decay. It should have very little scent, and the presence of these smells indicates that bacteria have started to affect the cells, causing them to rot.
Don’t eat bok choy that has a strange smell; it could make you sick.
Conclusion
The presence of brown spots on your bok choy is often a sign that the vegetable is starting to go off. You should check for other signs of freshness, including the leaf greenness, the stalk texture, the taste, and the scent, to determine if it’s still safe to eat.
