What are the small black dots on the cauliflower and what is the cause of the cauliflower black dots

1.There are several reasons for the appearance of small black dots on cauliflowers, the first reason is caused by improper temperature and light. For this reason, we can use a knife to peel off the black color on it, and it does not affect the consumption.

2.The second reason is that there are some pests and diseases. After we have cut off the black with a knife, we put the cauliflower in water and soak it in salted water for 20-30 minutes. Remove pesticide residues and consume normally.

3.Thirdly, it is best to blanch the cauliflower with water before cooking, which is safer and tastes better when eaten. Also, cauliflower must be cooked before eating.

4.If the cauliflower is too humid in storage, there will be black spots, we must store the cauliflower in a cool and ventilated place when we preserve, and often turn it to check, once it is found that there is deterioration, remove it in time.

5.If the average family buys more cauliflower at one time, you can wrap it in paper and store it in the refrigerator to store the cauliflower in the refrigerator, usually not more than a week and use it as soon as possible to avoid spoilage.

If there are only a few black spots on the cauliflower, and the spots are only a few on the surface, then such a cauliflower is edible, all we have to do is peel off the black spots on the cauliflower before cooking. If the black spots are flaky and the spots are deep, then it is best not to eat them, the black spots are actually a sign of mold on the surface of the cauliflower, sometimes because of the trauma that causes the black spots. If less is edible, more means that the cauliflower has spoiled, and it is best not to eat it.

Causes of cauliflower black spots:

Cauliflower may develop dark spots during growth and preservation.

Cauliflower storage method:

Store at room temperature. Placing cauliflower in a low-temperature, dark, and ventilated environment can prolong the shelf life of cauliflower, and it can be stored for a week if the environment is good.

Cryostorage. Wrapping the cauliflower in plastic wrap and putting it in the freshness layer of the refrigerator is the best way to preserve it, but do not put it in the freezer, if the temperature is too low, the cauliflower will freeze to death.

If you use a plastic bag to preserve, remember to prick a few small holes to avoid dew condensation inside, and if there is dew, the cauliflower will spoil faster. It is recommended to eat and buy now, and do not "stock up".
