What s the matter with black rice soaked in water and not fading

The red and black rice in the real grain field will also fade when soaked in water, but the loss is not as serious as the dyed black rice! Dyed black rice is black when soaked in water, like ink, while real black rice is burgundy! Here are three ways to tell the real from the fake, and I'm glad to share them with you!

The first trick: look at the appearance. Generally, the shape of black rice is uniform, but the color is not very uniform. On the other hand, dyed ones are uniform in color but uneven in shape. And if you look closely, real black rice will have rice grooves and textures, and fake black rice generally does not have rice grooves.

Trick 2: Smell the smell. Black rice is a type of rice, and real black rice smells like rice. Fake black rice definitely doesn't have it, and the black rice dyed by hand feels very bad.

The third trick: wash it. Black rice will appear purple-red when soaked in water, and the higher the water temperature, the darker the color. After the dyed black rice is soaked in water, it generally appears ink-colored and is easy to rot.

The color of black rice fades because the black color of the surface layer of natural black rice is a water-soluble pigment, and the higher the water temperature, the more unstable it is. This means that in the process of boiling black rice, the black rice will fade.

It is not clear as for not fading.

The instructions may be fakes. Because the black color of the surface layer of black rice is a water-soluble pigment, under normal circumstances, black rice will fade when soaked in water.

Black rice fading is a normal phenomenonBlack rice fading is a normal phenomenon because the appearance of black rice is black, and its surface contains water-soluble pigments, that is, anthocyanins.

Yes. Because the surface layer of black rice contains water-soluble pigments, anthocyanins. Anthocyanins can easily dissolve in water after contact with water, causing water discoloration.

However, although the surface layer of black rice is black, the rice core is white, and if the outer layer of black rice is rubbed during the washing process, revealing the white rice heart, it is also a normal phenomenon. <

Black rice is a kind of rice that is used both for medicine and food, and belongs to the glutinous rice category. Black rice is a characteristic variety formed by long-term cultivation of grasses. There are two types of grain types: indica and japonica, and the grain is divided into two types: waxy and non-waxy.

Brown rice is black or dark brown in color. Black rice is dark in appearance and rich in nutrients, and has the reputation of black pearl and the king of rice in the world. It is produced in many places in China, and the representative ones are Shaanxi black rice, Guizhou black glutinous rice, Hunan black rice, etc.

1. It is normal for black rice to fade.

It is normal for black rice to fade because it has a black appearance and it contains water-soluble pigments called anthocyanins. Anthocyanins are easily dissolved in water after contact with water, causing water discoloration, so normal black rice will fade during the washing process. However, although the surface of black rice is black, its rice core is white, if in the process of washing, the outer layer of black rice is rubbed, revealing white rice heart, everyone should not worry too much, this is also a normal phenomenon.

2. Black rice will fade slightly.

In fact, it is a normal phenomenon for black rice to fade, because even if it is natural black rice, the black color on its surface is a water-soluble pigment (anthocyanins), and the higher the water temperature, the more unstable it is.

3 In fact, black rice naturally fades, and it can still be eaten. Even if it is not subjected to high temperatures, as long as you soak the black rice for a period of time, the water will turn purple-brown, which is a normal phenomenon. Some experts remind that when washing black rice, in order to reduce the dissolution of pigments in water, it is recommended to gently wash with cold water.

In addition, it should be noted that although black rice will fade, and it is normal, but if you put it in cold water and immediately change color, it means that there is a problem with this black rice, and this faded black rice should not be eaten!

On the dining table of every family, there are many staple foods such as rice, noodles, steamed buns, and pancakes cooked with refined white rice noodles, and it is rare to see coarse grain rice. In recent years, more and more people, for the sake of their health, are slowly eating whole grain rice, that is, on the basis of rice, some whole grains will be added.

For example, the overall nutritional value of black rice is very high, especially the vitamin B content, iron content, and crude fiber content in black rice are very high, which can not only make up for the nutritional deficiency of rice, but also help relieve constipation, as well as prevent mouth ulcers, iron deficiency anemia and other benefits.

It is a way of eating that should be done every day in life now, and it is not necessary for everyone to put in all the black rice, for people with metabolic diseases such as the three highs, it is enough to put in 1 3 whole grain ingredients, which can also be accepted by more people. And because black rice itself is very chewy, it is more suitable for people to make rice. Before cooking, some people will soak the black rice in water in order to have a good taste, but after 20 minutes or half an hour, why does the black rice fade?

This made many people panic, thinking that there was something wrong with the black rice they bought?

For this situation, in fact, you really don't need to be afraid or worried, this phenomenon is the anthocyanin component in black rice. When soaking or washing black rice, the water may change color. In addition, rice cooked with black rice is not white, and even if a small amount of black rice is added, the final steamed rice tends to turn purple or black.

These phenomena are due to "anthocyanins", anthocyanins can be soluble in water, and it is a very good ingredient, strong antioxidant capacity, has the benefits of eliminating free radicals in the body, skin care, anti-aging and so on.

In addition, the reason why you don't have to worry about it is that you can carefully observe the black or purple foods in your daily life, such as mulberries and blueberries, which are also prone to color loss after touching water.

If you want to determine whether the food you buy is discolored because of "anthocyanins", you can put a little baking soda in the soaked water, and it won't take long for the water to turn blue-green. It means that the food you buy is safe and not the result of dyeing or using some kind of reagent. For such food, everyone can eat it safely and with confidence.

If, after a small experiment, no blue-green color appears. You can also change the experiment and put the ingredients of white vinegar in the water soaked in the food, and the water turns red, which also indicates that the anthocyanins are responsible. If you don't have any, you really need to be vigilant.
