How to identify dyed peanuts? What is the difference between red peanuts and white peanuts?

Peanut kernel refers to the part without the shell, which is actually the seed of the peanut. The whole peanut is called the fruit or pod. It is also called peanut rice, ground peanut, ground fruit, and Chinese bean. Peanuts are good for nourishing and can prolong life, so they are also called "longevity fruit" by the people. Like soybeans, they are also known as plant meat and vegetarian meat. The nutritional value of peanuts is higher than that of grains and can be comparable to eggs.

How to identify dyed peanuts

1. Observe the appearance

Some peanuts have "little white spots" on one end, which is because the red skin of the peanuts is stretched open to reveal the color inside. If the peanuts are dyed, these exposed "little white spots" will definitely be dyed red.

2. Observe the inside of the red shirt

Because the red skin is very thin, if the peanuts are dyed, the color will penetrate the red skin. After peeling off the red skin, you can see that the inside of the red skin is also light red.

3. White paper friction

Put a wet red peanut and a soaked red peanut on a piece of white paper and rub them hard. Although the white paper is wet, there is no red on the paper. If the peanuts have been dyed, they will fade when they are damp or wet, and rubbing them hard on the white paper will leave red. Whether the black rice is dyed can also be identified in this way. There is another misunderstanding that needs to be pointed out. Not necessarily faded peanuts are dyed. According to agricultural experts, many peanuts with red skin (such as hibiscus) are darker in color because the red skin of peanuts contains more natural pigments. After red peanuts are soaked or boiled in water, the water will turn light red, which is a normal phenomenon. Mung beans, black beans, red beans, etc. will also change color after being soaked in water.

What is the difference between red peanuts and white peanuts?

1. Different ways of eating: White peanuts are very large and have a high oil yield. They are crispy and very suitable for deep-frying or cooking. Red peanuts are smaller than white peanuts and taste slightly sweeter. They are suitable for making soup or cold salad.

2. Different nutritional value: Red-skinned peanuts have slightly higher nutritional value than white-skinned peanuts. The red skin of peanuts can inhibit the dissolution of fibrin. Red peanuts are a type of peanuts with a redder skin. They are more popular than traditional peanuts because their color is obviously redder. In fact, the red skin of red peanuts is richer in iron, so the color is brighter red than traditional peanuts.

Can you eat expired peanuts?

Expired food will breed a large number of bacteria and may cause food poisoning, so it is best not to eat it.

Long-term consumption of expired and bitter peanuts may increase the incidence of diseases such as liver cancer and esophageal cancer. However, occasionally eating a few peanuts will generally not cause major adverse effects on the body.

It depends on your storage method. Different storage methods have different shelf lives.

The first method: first dry the peanuts for 4-5 days, rinse them with clean water, and then blanch them in 100℃ boiling water. After 15-20 minutes, put them in a plastic bag or put 1-2 cigarettes and dried chili slices in the container of peanuts, cover the mouth tightly, and store it in a dry place. It can be kept without deterioration for 1 year.

The second method is to blanch the peanuts in boiling water, then quickly take them out and dry them. This can kill the bacteria on the surface and also prevent insects and mildew.

The third method: Place the raw peanuts in a container and dry them in the sun for 2-3 days, then let them cool, put them in a plastic food bag, seal it tightly, and refrigerate it in the refrigerator. They can be stored for 1-2 years and can be eaten, taken out, and processed at any time without going bad.
