What causes ginger to become blue?

If you keep some types of ginger for many days or weeks in a chilly environment like your refrigerator, the ginger may become a blue color. Garlic, which may occasionally become blue but is still edible, demonstrates the same characteristics.

Sometimes the blue color in ginger is quite subtle and hard to see. At other times, the ring is a brilliant shade of blue all the way around. Having said that, it does not necessarily have to be the refrigerator. You could keep it in a very cold pantry, or you could keep it in the location where the previous owner stored it before you bought it from them.

Since it is rich in anthocyanins, ginger takes on a blue color rather than another hue when cooked. There is a wide range of anthocyanin content found in ginger, depending on the variety. These are antioxidants and pigments that can be found in every berry and red fruit, including red cabbage, purple carrots, red onions, cherries, blueberries, and cranberries, despite their odd-sounding names. Cranberries, blueberries, and cherries are all red fruits.

The color of anthocyanins may change from red to blue. When they are in an acidic state, red fruits and vegetables, such red onions, appear red. The color change from green to blue occurs when the pH of the fruit or vegetable is alkaline.

Ginger undergoes a modest alteration in its chemical make-up after being exposed to low temperatures for a lengthy period of time. As a consequence of this, the surrounding area of the outer ring begins to take on a bluish cast as the alkalinity of the solution increases.

Why is my ginger root becoming blue?

Anthocyanins, which are found in ginger, are a kind of chemical that will become blue in the presence of acids. This is the same chemical that may make garlic blue under certain conditions.

This is something that is only found in specific types of ginger since some ginger varieties in Japan have the chemicals in question whereas ginger varieties from China do not. Since ginger has a pH that is somewhat on the acidic side, it most likely triggered the response.

In general, blue-tinged ginger is safe for food; nevertheless, you should be aware that naturally occurring bluish colours on ginger are fairly uncommon. Also, due to the fact that it is an antioxidant that emits blue colours, you can discover that consuming it is really advantageous to your health.

Is blue ginger toxic?

No, blue ginger is not toxic. On the contrary, it may be consumed without any concerns. The main distinction between the two types of ginger is that blue ginger has a more subdued taste than yellow ginger. On the other hand, when it comes to cooking, you won’t be able to tell the difference.

Is it safe to consume blue ginger?

It’s quite safe to consume blue ginger. There’s no need to be concerned if your ginger did this. You should still be able to use it.

It is still okay to use the ginger in any of its many applications as long as it does not have a moldy smell, is not slimy, and does not have a moldy appearance. That can be odd at first, but everything will work out in the end.

One important point to keep in mind is that blue ginger has less acidity, which contributes to its improved flavor. The taste, on the other hand, is not as robust and is not nearly as hot as it was in the past.

Is it possible to become ill from blue ginger?

No, blue ginger cannot make you ill since the blue colours that may happen to ginger are entirely separate from the ginger itself. When ginger’s anthocyanins are acid-washed, a blue color emerges. The blue color of garlic is caused by a molecule that is chemically identical.

The flavor is the only aspect that the blue colours have any influence on. The taste of blue ginger is more subdued than that of regular ginger. Other from that, consuming blue ginger won’t make you ill in any other way.

How can you know if your ginger has gone bad?

If there is mold on your ginger, then you can safely assume that it is spoiled. You can, however, determine if it is time to throw it out before mold begins to grow on it.

You will be able to determine whether or not it is time to throw away the ginger as it dries out on the counter. It begins with a fresh rhizome that has a skin that is quite smooth and ends with a piece of ginger that is wrinkled and matte.

You could believe that ginger would keep for a longer period of time if you store it in the refrigerator. On the other hand, it has a shelf life of up to two weeks if kept at room temperature. You will use up every last bit of it inside the following fortnight. Ginger is definitely consumed in some form (tea, sauce, or anything else) in your culture.

While not all ginger knobs do, most of them exhibit an unusual reaction when exposed to cold temperatures. Certain plants, for instance, have a higher anthocyanin content than others, which is what causes them to become blue sooner.

As long as the blue ginger does not have any mold on it or a strange odor, you may continue to eat it. But if you’re not sure about it, you can always toss it away and get something else.


Anthocyanins, to summarize, are the pigments that give blue ginger its color. The pigment anthocyanin is responsible for the vivid colors that are seen in plants. Ginger, on the other hand, may become a bluish color if it is kept in a chilly climate. Even though it can seem dangerous, there is no need to worry about whether or not it is safe to consume.

Some folks may find the blue tones unpleasant due to their appearance. On the other hand, this behavior is only the product of a ginger’s sensitivity to being in chilly conditions. While blue ginger is unfamiliar to us, there is no need to be concerned about its safety as a food ingredient.
