How to know if cauliflower is spoiled?

Brown spotting on the surface of the cauliflower indicates spoilage. If the cauliflower has soft spots or a slimy texture then this also tells that the cauliflower is spoiled. If you experience a foul smell or you observe mold growth on the surface of the cauliflower then this also indicates that the cauliflower is spoiled and should be thrown away.

Cauliflower originated from an Italian term cavolfiore, meaning “cabbage blossom”. A white floral crest makes up the cauliflower head. Cauliflower heads are similar to broccoli heads, with the exception that the consumable section is blossom buds.

When compared to cabbage, cauliflower is harder to cultivate. The most frequent color for cauliflower seems to be white, which has a contrasting white crown surrounded by green stalks. The orange component of orange cauliflower is beta-carotene. 

In purple-colored cauliflowers, anthocyanins, water-soluble compounds are present in several other plants and vegetable products and are responsible for the purple color of cauliflower.

There are several ways to tell whether the cauliflower has gone bad or not. Some of the methods are discussed below:


Using your nose as a guide is typically a smart idea. When cauliflower becomes rotten, it has a distinct odor. If you purchase cauliflower in packaging that has already been chopped, sliced, it is more certain to have an odor. I would advise tossing it if you feel the fragrance to be unpleasant.


One of the most prevalent difficulties regarding cauliflower is this one. The spots are almost always induced by oxidation. 

The cauliflower oxidizes and turns a bit brownish from the head. It is still edible but it won’t be very appealing. You can chop the spotted portion of the cauliflower and consume the rest of the edible portion of cauliflower.

The spots may be taken out if desired; they are just on the outside.


Softness, on the other hand, is a different matter. This indicates that the cauliflower is beginning to decompose. This occurs almost all of the time when there is too much wetness present. The majority of cauliflower is packaged in plastics, which is wonderful for transportation but not so great for keeping in our fridge.

If the plastic is firmly packed, I suggest puncturing small holes in it to allow water to escape. Alternatively, re-wrap it again in plastic just let it be more freely wrapped.


Checking sliminess is the next step from inspecting softness. If you feel that the texture is not looking healthy enough then this means that the cauliflower is spoiled. But in some cases, slime texture doesn’t need to indicate spoiled cauliflower. You can also confuse the moisture on the cauliflower head with sliminess. 

If you don’t detect mold, chopping off the slimy region isn’t an issue for me.


If somehow the cauliflower was very tightly wrapped, I might fall on the side of danger and chuck it all away. If it wasn’t encased in plastic, I’d probably chop out a large chunk of it. In most situations, a fresh head of cauliflower is required. 

If you can see some kind of mold growth then it is better to toss such cauliflower away and don’t consume it at all. Observing mold growth gives a strong sign that the cauliflower is spoiled.


A fresh cauliflower can last at room temperature on a shelf for up to three to five days. If the cauliflower is refrigerated, then it can stay edible for up to 8 to 15 days. Cooked cauliflower can stay good in the refrigerator for about 5 to 6 days. 


Fresh cauliflower is 93 percent water, 6% carbs, 1% protein, and has no lipids. Fresh cauliflower contains a high amount of vitamin C and moderate amounts of various B vitamins and K vitamins in a 100-gram reference quantity, providing 104 kJ of dietary energy. The number of dietary fibers is relatively low.


If you eat spoiled cauliflower, then you might usually get foodborne illnesses. You might get an upset stomach. Symptoms like nausea, vomiting, abdominal pain, stomach cramps, diarrhea, and many other symptoms are likely to cause. If the symptoms get worse, then it is highly recommended to see a doctor immediately.
