What s the deal with the black hair of the beans in the sauce?

It is normal for black hairs to appear in the beans, because it is a sign of normal fermentation, as long as there are no obvious green hairs to observe, it doesn't matter.

Because that green hair is aflatoxin produced by improper fermentation.

This substance contains toxins that can cause food poisoning if consumed.

It is harmful to health, so it is better to be cautious in this regard.

Long black hairs are fungi growing. There are two kinds of soybean paste long hair: one is filial piety, the long hair on the surface of soybean paste is normal, and the surface hair can be removed and put in a cool place to eat; The second type of long hair, the sauce stinks, or it does not smell all the sauce has long hair, then it cannot be eaten.

The correct way to make soy beans: Preparation of ingredients for soy beans: 1000 grams of soybeans, 500 grams of salad oil, 50 grams of sesame oil, 200 grams of shredded ginger, 4 taels of salt, 2 catties of chili peppers, 150 grams of sugar, 50 grams of chicken essence, star anise, pepper, pepper powder A total of 20 grams 1, soak soybeans in clear water for 7-8 hours, remove the dry water, divide and then steam for 30-45 minutes, turn off the heat, do not lift the lid, and simmer for 2-3 hours.

2. Wash and chop the green and red peppers, add star anise, pepper powder, and salt to stir evenly and marinate for 7-8 hours, (1-2 parts can be done at the same time). 3. Put oil in the pot, put the steamed soybeans in the pot and fry them for 3-5 minutes. 4. Put a little oil in the pot, put in sugar, pour fried soybeans and pickled chili peppers into the pot, add sesame oil, rapeseed cooked oil, chicken essence monosodium glutamate and other seasonings according to your preference, and stir-fry evenly.

5. Simmer and fry for 20 minutes on low heat, it is very delicious.

Put the gauze bean pot in the sun, stir it once in the morning when you move it out, and then move it back indoors in the evening to prevent rain. After drying for half a month, you can fry and eat after smelling the fragrance of the sauce. It can't be used, white hair can, but black hair will have diarrhea if you eat it, and you may also get food poisoning in severe cases.

Let me talk about it: you need to use soybeans, soak them in water for two days to become big fat beans, and soak them thoroughly! Then wash and drain the water, at this time the beans are wet, sprinkle with dry flour and mix well, so that you can not see the soybeans but only the white flour.

beans, and the surface is dry and loose slightly off the flour for degrees. Then make a quick clean place at home, preferably a flat bed, unpack the large cardboard boxes that are not used for electrical appliances at home, spread them flat, wipe them clean, spread two layers of white paper, and buy them at the stationery store if they don't; You can't use newspapers, there are inks on them that contain heavy metals such as lead, and there are bacteria; Or use a clean white cloth or gauze, to be cotton, after paving, the dough beans are evenly spread, the area is slightly larger, do not build up, the dough beans should be dry and loose on the surface but damp, and the white paper is slightly wet. Then cover with a white cloth or white paper, pat it gently, and the surrounding nest is tight, not breathable, and do not let air bacteria enter.

Cover it thicker and cover it with a layer of sheets, but keep it clean!

In addition, the weather is also very important, and it is best to choose the toon tree.

When the young leaves come out, it is just right to make soy beans, probably in July of the Gregorian calendar, avoiding yellow plums.

Rainy weather, stable climate is conducive to making good sauce beans, catch up with the rainy day is not good, easy to do bad. If the weather is sunny in a row, it means that the sun is big during the day, and it will be covered for about four or five days; If the weather is sunny and cloudy, about a week or so, try not to open it in the middle to check, it is not good for air bacteria to get in.

Cover the beans so that you can't see the white beans.

For best, take the green mold covered with green.

Powder flying is the most classic, and then carefully put away the moldy beans that have been covered and moved to the sun, evenly spread out and blown out for a day to remove the mildew in order to dry and loose, put it in a container for later use, and then it's up to you! Ha ha! Yes!

The soy sauce has black hairs, which proves that the soy sauce has been contaminated. Try to find a stuffy and humid room, do not open the doors and windows frequently, spread the beans on clean paper, and spread a layer of paper with good air permeability on the spread soybeans (when the temperature is low in spring, you can cover the paper, and then cover a layer of towel quilt to facilitate the fermentation of beans).

The reason for the black hair is that you don't do it right and don't control the details. The correct way to cover the beans: The first step is:

Boiled beansWash the selected soybeans in cold water, put them directly in the pot and add tap water, not to about two fingers deep on the soybeans. Then start boiling the beans like braised rice, and cook the beans until they taste slightly noodlesy. After the beans are removed, they are placed on a sieve overnight to cool thoroughly.

After the soybeans are cooled, start to mix the noodles: evenly coat the soybeans with a thin layer of noodles that do not stick to each other. If the beans are too dry to mix, pour a little of the boiled bean water on top of the soybeans to the extent that they can coat the dough.

The second step is to cover the beans: spread three or four layers of newspaper on a wooden board or some breathable material (avoid glass plates or plastic), and then spread a layer of clean white paper or kraft paper on the newspaper. Spread the mixed soybeans evenly on a white paper about a finger thick.

Spread a layer of breathable paper on top of the spread soybeans. Do not open the doors and windows of the room to cover the beans frequently, try to maintain a stuffy and humid environment, and cover the paper with a towel quilt when the temperature is low in spring, which is conducive to the fermentation of beans.

It should be that the air entered during the covering, or the temperature of the cover was not right, which affected the fermentation, so it led to the growth of black hair. The beans are black and can't be eaten, and the black is Aspergillus niger.

and Aspergillus griseus, and the amount of bacteria in the long hair is 10,000 times that of normal beans.

In fact, you only need a bowl of soybeans to make soy sauce, so let's take a look at the specific production method.

1. First of all, we first soak the prepared soybeans in water for more than three hours to detect the bad beans inside, then remove the dry water, and put the soybeans in the pressure cooker.

among the cooked. 2. In the process of boiling soybeans, we are preparing other things, first flour and oatmeal.

Pour into a pan without water or oil and sauté over low heat until browned.

3. After the soybeans are cooked, then we take out the soybeans and put them in a flat container to cool.

4. Then we pour the fried flour, barley beer and soy sauce koji essence into the container, stir well with chopsticks, and finally add bright soybeans and put them in this way to ferment in a warm place for about 24 hours, at this time we will find that a layer of white mycelium appears on the surface of the soybeans.

5. At this time, the soybeans will stick together, and then we turn the soybeans over and continue to ferment for 24 hours.

6. After the surface of the soybeans is covered with green robes, we take the soybeans to a plate, add an appropriate amount of saturated brine, the water must not cover the beans, and finally sprinkle a layer of salt. It is left in the sun for about three months to make a sauce mash.

7. After the sauce mash is ready, we soak the sauce mash in salt water three times, once for about three days, and then soak for about 7 days.

8. Then we mix the sauce that we sucked out three times at home and expose it to the sun for about 10 days, and finally add star anise tangerine peel to it.

The cloves are boiled at home and the liquid is finally added to MSG.

White wine, brown sugar, edible salt.

After stirring well, the salt is concentrated to 17%, and finally boiled and strained in a pot to make a delicious soybean soy sauce.
