Put the peppercorns, spices, salt, etc. into a container, add the peeled and mashed garlic, and then put the washed peanuts into the container and mix with the seasoning. Then pour in boiling water until all the peanuts are soaked. Add the lid and soak for 2 to 3 hours, remove and spread out to dry.

2 Stir-fry: Put clean sand grains in a large pot that is washed and dried, stir-fry over heat, and pour in the dried peanuts in time. Stir-fry until there is a crackling sound, and when the peanuts are easy to peel by twisting by hand, switch to a simmer and fry for a few minutes to get out of the pot.

Sift away the sand, and the remaining peanuts are spiced peanuts. In the process of frying peanuts, stir often to avoid burning and frying the peanuts.

First of all, check whether there is a quality problem with the peanuts themselves? If there is no problem with the peanuts at all, it is what chemical reaction happened between the peanuts and the pot, and the stainless steel pot is changed.

When a chemical reaction occurs, don't use an iron pot, preferably a stainless steel pot.

The aluminum pot will not turn black when boiled, and the iron pot will.

Wash the iron pot better.

1. Don't use an iron pot.

2. Don't use color-colored seasonings.

3. Take it out and put it in the refrigerator after flavoring.

Method: 1. Fresh peanuts are repeatedly washed in water, boiled in water for 5 minutes, and then drained. As shown in the figure below:

2. After cooling, pinch the olecranon of each peanut to form an opening to facilitate the flavor. As shown in the figure below:

Nutritional value of peanuts:

Peanuts contain 25% to 35% protein, mainly water-soluble protein and salt-soluble protein, water-soluble protein is also known as whey protein.

It accounts for about 10% of peanut protein, and salt-soluble protein accounts for 90% of peanut protein.

Salt-soluble proteins mainly include arachidon globulin and concomitant arachidonin, which is made up of two subunits.

composed of dimers.

Associated peanut globulin is made up of 6 to 7 subunits. The protein in peanuts is not nutritionally different from animal protein, and it does not contain cholesterol.

Peanut Protein The peanut protein has a biological value of 58 and a protein titer of 58, and its nutritional value is second only to soy protein among plant-based proteins.

The value of peanuts.

Lowers cholesterol: peanut oil.

It contains a large amount of linoleic acid.

This substance can decompose cholesterol in the human body into bile acids and excrete them from the body, avoid the deposition of cholesterol in the body, and reduce the cause of a variety of cardiovascular and cerebrovascular diseases caused by cholesterol exceeding normal values in the human body.

incidence. Delay human aging: The zinc content in peanuts is generally higher than that of other oil crops. Zinc can promote children's brain development and enhance the brain's memory function; It can activate brain cells in middle-aged and elderly people.

It effectively delays the premature aging of the human body and has an anti-aging effect.

Method: 1. Shelled peanuts, scrub repeatedly, wash clean, put the shell into the pot without sticking to the shell, and the color is not black.

2. Put an appropriate amount of peppercorns, star anise, and salt, and be careful not to be too salty.

How to make boiled peanuts in the shell not stick to the shell.

Before cooking, put it in the refrigerator and then cook it, o(o, eat happily.

The reason why boiled peanuts turn black is because of a substance called tannic acid contained in them. Tannic acid is a natural protective substance that protects peanuts from damage from insects, bacteria, etc. However, when peanuts are heated and cooked, the molecules of tannic acid break off, releasing a colored compound called "melanin" that turns the peanuts black.

Melanin not only affects the appearance of peanuts, but also their taste and nutrient content. Black tubain is a polyphenolic compound that has some antioxidant effects, but too much melanin can make peanuts bitter and affect the taste. At the same time, melanin also reduces the nutritional value of peanuts because it combines with other nutrients to form a complex that is difficult for the body to absorb.

In addition to tannic acid and melanin, the blackening of boiled peanuts may also be related to the variety and origin of the peanuts. Some varieties of peanuts contain more tannin and melanin, and tend to turn black more easily. At the same time, the growth environment of peanuts may also affect their tannin and melanin content, such as soil pH, moisture and other factors will affect the quality of peanuts.

To avoid the peanuts from turning black, you can soak the peanuts before boiling them. Soaking can dissolve some of the tannic acid and reduce the production of melanin. In addition, adding the right amount of salt when boiling peanuts can also reduce the chance of peanuts turning black.

At the same time, choosing better quality peanuts and the correct way to cook peanuts are also effective ways to avoid peanuts turning black.

In short, peanuts are decomposed to produce melanin during heating because of the tannic acid they contain, causing peanuts to turn black. The process is also related to the variety and origin of the peanut. To avoid the peanuts from turning black, soak them or add salt before boiling them.

At the same time, it is also very important to choose better quality peanuts and the correct way to cook peanuts. <>

Three: Be sure to take it out just after cooking, dry the water, and not soak it in water. If the weather is good, it is best to put it in the sun while it is hot, and dry it to keep the water in the peanuts.

If you want the peanuts not to be black, you can add the peanuts after the water is boiled, boil the water for a while, and then add water to boil again, so that the boiled peanuts will not turn black.

The reason for the blackening is because the peanuts oxidize during the process of boiling them in an iron pot.

Boiled peanuts can also be eaten if they are blackened, but there is a little reaction on the shell, but it will not harm the health of the human body.

Do not pour out the water in which the peanuts are boiled, let the peanuts always soak in this juice, and take out some when eating.

I used an aluminum pot to cook it and it was blackened.

Before boiling, boil the water with boiling water, and it is recommended to soak it in water after boiling.

Are there any additives that are not easy to blacken?

Wait a minute, I'll find it for you.

Don't want any food additives! We usually boil peanuts with salt, dried chili peppers, and star anise, and the peanut shells will not turn black.
