Is black rice all black inside and out, or is it just black on the outside? Does black rice fade?

Black rice is a kind of rice that is used both for medicine and food, and the rice quality is good. The planting has a long history, and it is produced in many places in China, including Shaanxi black rice, Guizhou black glutinous rice, Hunan black rice, etc. 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. The main nutrients (brown rice) are crude protein, crude fat, carbohydrates 75-84 and crude ash in terms of dry matter. The content of vitamins, trace elements and amino acids is higher than that of ordinary rice.

It has high edible value, and in addition to cooking porridge, it can also make a variety of nutritious foods and sake brewing. Modern medicine has confirmed that black rice has the effects of nourishing yin and nourishing the kidneys, strengthening the spleen and warming the liver, brightening the eyes and invigorating the blood. Most of the nutrients contained in the black cortex are concentrated, so it is not suitable for refining, and it is advisable to eat brown rice or standard third-class rice.

When cooking porridge, soak the black rice in water for one day and night in summer, and soak it for two days and nights in winter, the number of washing times should be less, and the water for soaking rice should be boiled with rice to preserve nutrients.

Identification of counterfeit and inferior products.

At present, there are two common cases of black rice adulteration on the market, one is substandard or inferior black rice that has been stored for a long time, and it is shoddy after dyeing**; The other is to use ordinary rice that is dyed and then filled with black rice**. Natural black rice will also fade after washing, but it is not as powerful as dyed black rice. Consumers can make sensory identification from the following aspects when buying black rice:

One look: look at the color and appearance of black rice. Generally, black rice is shiny, the size of the rice grains is uniform, there are few broken rice, bursting loins (cracks on the rice grains), no insects, and no impurities.

The color of inferior and inferior black rice is dull, the size of the rice grains is uneven, the fullness is poor, there are many broken rice, there are insects, there are lumps, etc. For dyed black rice, because the black color of black rice is concentrated in the cortex, the endosperm is still white, therefore, consumers can scrape off all the outer cortex of the rice grains to observe whether the rice grains are white, if not, it is very likely to be artificially dyed black rice.

Second smell: Smell the smell of black rice. Take a small amount of black rice in your hand, take a hot breath on the black miha, and immediately smell the smell.

High-quality black rice has a normal fragrance and no other peculiar smells. Slightly peculiar smell or mildew odor, sour odor, rotten smell and abnormal smell are inferior and inferior black rice.

Three tastes: taste the taste of black rice. You can take a small amount of black rice and chew it in your mouth, or grind it before tasting it. High-quality black rice tastes good, slightly sweet, and does not have any peculiar smell. Black rice with no taste, slight peculiar smell, sourness, bitterness and other undesirable tastes is inferior or inferior.

Black rice is black in appearance. It's not very dark inside, and the water turns purple when you soak it in water.

Black rice is white on the inside. Generally speaking, the heart of ordinary black rice is white, and the black rice only looks black on the surface, don't think that the inside is also black. Like the heart of ordinary rice, the heart of rice is transparent, and the heart of black rice is white, but if it is dyed with rice, although the surface of the black rice looks normal, the heart of the rice will definitely be penetrated by the pigment and turn it into black or a very strange color.

The inside of the real black rice is white, if the inside of the black rice is also black, it may be the black rice dyed by others, at this time you should pay attention, when you take the black rice, you can scrape the surface of the black rice, see if it is white, if it is white, then it is real black rice. The black color of black rice is mainly concentrated on the surface of the rice, and the endosperm inside is still white, so you must pay attention to it.

The inside of the black rice is not black, but there are some red black rice, but the appearance is black, but its interior is not a pure black structure, so we named him according to his appearance and color.

The inside of the black rice is not black, I took a bite and saw that the inside was white, because the black rice is black on the outside, so the cooked porridge is black.

Black rice has a higher anthocyanin content, and the color inside is lavender.

Black rice is like this, normal.

Under normal circumstances, the normal rice heart of black rice is white, black rice only looks black on the surface, don't think that it is also black inside, just like the rice heart of ordinary rice, the rice heart of rice is transparent, but the rice heart of black rice is white, but if it is black rice dyed with rice, although the surface looks normal, but the rice heart will definitely be penetrated by the pigment into black or a very strange color.

Both black rice and purple rice are precious varieties of rice and belong to the glutinous rice category. The main nutrients (brown rice) are crude protein, crude fat, carbohydrates 75-84 and crude ash in terms of dry matter.

The rice porridge boiled with black rice is fragrant and oily, soft and glutinous, rich in nutrients, and has a good tonic effect, so it is called"Blood-replenishing rice"、"Longevity rice"Wait; Chinese folk have"Every time it gets dark, it must be mended"said.

Black rice is only the surface of the rice skin is black, peel off the rice skin, the inside is still white, so the soak in water fades is...Authentic black rice has a natural rice fragrance after being soaked in warm water, and the dyed rice has a peculiar smell; 3. Touch: Authentic black rice is brown rice, and there is a rice groove on the rice.

Someone here replied that the outer skin of black rice is black, the inside is white or brown, and the inside is black is fake black rice, which is completely nonsense. I am in Chengdu, in the countryside of Xindu, the black grain of my father-in-law's house is all black inside and out, and it is also black outside. So when I bought black rice, I broke the rice and saw that there was no black one in it, so I didn't dare to buy it.

Speak with evidence, seek truth from facts, and don't mislead consumers, okay?

Black rice should be brown inside (close to black) White is not!

Black rice has a black or dark brown skin on the outside and white on the inside.

How to distinguish black rice:

Looking at the color, the normal black rice epidermis is shiny, while the dyed black rice is not shiny.

Looking at the epidermis, the epidermis that normal black rice scratches with its fingernails is flaky. If it's in powder form, it's low-quality black rice.

Looking at the rice heart, the rice heart of normal black rice is white. The kernel of ordinary rice is transparent and has no color. If the dyed black rice is dyed with regular rice, the color of the dye will penetrate into the heart of the rice and turn black.

Looking at the soaked rice water, the soaked rice water of normal black rice is purple-red, and it is also purple-red or reddish after dilution. If the water is diluted like ink and is still black, then it must be fake rice!

Add white vinegar, black rice water will turn green when it encounters alkali, and it will turn red when it encounters acid. Authentic black rice water turns red immediately when it encounters acid.

The inside is also black.

The general law of the nutritional value of food tells us that the darker the color of the same food raw material, the higher the nutritional value, and rice also conforms to this law. Therefore, the nutritional value of black rice is much higher than that of refined white rice. Melanin has an anti-aging effect.

The main reason why black rice is different in color from other rice is that it contains anthocyanin pigments in the outer cortex, which itself has a strong anti-aging effect. Studies at home and abroad have shown that the darker the color of rice, the stronger the anti-aging effect of epidermal pigment, and the effect of black rice pigment is the strongest among all colors of rice. In addition, this pigment is also rich in flavonoid active substances, which are five times more than white rice, and have a great effect on preventing arteriosclerosis.

Compared with refined white rice, the B vitamin content in black rice is about 4 times that of it; The content of trace elements such as potassium, magnesium, iron, zinc, and manganese is one of its times, 6 times, times, times and times respectively; The lysine content is 2 times that of it.

Since ancient times, black rice has been regarded as a nourishing health supplement.

The "Yutian rouge rice" mentioned in "Dream of Red Mansions" refers to the purple-black blood glutinous rice. Traditional Chinese medicine believes that black rice has the effect of nourishing yin and nourishing the kidneys, strengthening the spleen and warming the liver, brightening the eyes and invigorating the blood, and can cause a variety of diseases such as anemia, dizziness, blurred vision, and premature gray hair.

Since black rice contains more dietary fiber, starch digestion is slower, and the glycemic index is only 55 (compared to 87 for white rice), eating black rice will not cause blood sugar fluctuations like eating white rice. In addition, minerals such as potassium and magnesium in black rice are also beneficial for controlling blood pressure and reducing the risk of cardiovascular and cerebrovascular diseases. Therefore, diabetics and patients with cardiovascular disease can consume black rice as part of their diet.

It works best when used to cook porridge.

If the authentic black rice you bought is black, if it's white, it's dyed, but when the black rice is washed, it will fade a little bit of color, but it's not a lot, that's normal.

As far as I know, it's white.

The black color of most varieties of black rice is concentrated in the cortex, and the endosperm is still white.

1. If the black color penetrates into the rice core, it is very likely to be dyed black rice. In addition, the black color of the surface of natural black rice will not be very uniform, while the black color of dyed black rice is very uniform, and the real and fake black rice can be preliminarily judged through these two points.

2. The normal epidermis of black rice is shiny, while dyed black rice is not shiny.

3. The heart of normal black rice is white. The kernel of ordinary rice is transparent and has no color. If the dyed black rice is dyed with ordinary rice, the color of the dye will penetrate into the heart of the rice and turn black, so be careful.

My family has bought black rice, and I think that the soaked rice water of normal black rice is purple-red, and it is also purple-red or reddish after dilution. If the soaked water is still black after being diluted like ink, it is fake rice, so pay more attention to it

It's black, and it's black on the inside.

How to identify its quality: The first trick is to look at the shine. The normal epidermal layer of black rice is shiny, and low-quality black rice has no luster.

The second trick is to look at the epidermis. Normal black rice is flaked when picked by hand, and if it is powdered, it is inferior black rice.

The third trick is to look at the rice heart. The kernel of normal black rice is white, while the kernel of regular rice is transparent and has no color. Black rice dyed with rice has a uniform appearance, but the color of the dye penetrates into the heart of the rice.

The fourth trick is to soak in rice water. The soaked rice water of normal black rice is purple-red, and it is also purple-red or nearly red after dilution. If the water bubbled out is like ink, and it is still black after dilution, this is fake black rice.

It's not all black, it's a bit of a bean paste.

Drop the color.

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 that of dyed black rice. Dyed black rice is black when soaked in water, like ink, while real black rice is burgundy.

Ways to distinguish the real and fake black rice:

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.

It is normal for natural black rice, triticale and other "black five" foods to fade. The black color of the surface layer of natural black rice is a water-soluble pigment, the higher the water temperature, the more unstable it is, and in the process of boiling black rice, the higher the temperature, the faster the black rice will fade. However, it cannot be denied that there are indeed colored fake black rice on the market, which requires consumers to carefully identify when buying.

From the color, taste and texture, you can distinguish the quality and authenticity of black rice. First of all, look at the luster: good black rice has a shiny surface, uniform size of rice grains, and less broken rice; Bad black rice hair black; Secondly, smell the smell, take a small amount of black rice to take a hot breath, and then smell it immediately, good black rice has a normal fragrance and no peculiar smell.

The black color of natural black rice is concentrated in the cortex, and the interior is still white, which is very contrasting; However, dyed black rice will penetrate into the inside due to the dye, and the white color inside the rice grain looks impure and unnatural. You can also taste the taste of black rice, take a small amount of black rice and put it in your mouth to chew, or grind it and taste it, high-quality black rice tastes good, slightly sweet, without any peculiar smell; Tasteless, slightly peculiar, sour, bitter and other undesirable tastes are inferior, inferior or fake black rice.
