Can you eat flour with black bugs, and why does flour give birth to black bugs?

There are a small amount of black bugs in the flour that can be eaten, and a large number of black bugs that cannot be eaten.

Flour worms are related to the storage method of flour. Store in a damp, dark, and closed place to make the flour moist and easy to cause insect infestations.

If there are not many small black worms, you can dry the flour in the sun to pick out the small black worms, which will not affect the consumption.

However, if there are more small black worms, then you can no longer eat them, this small worm can secrete a smelly liquid, so the flour will have a moldy smell, so it is recommended not to eat it.

Usually buy too much bulk flour, you will find that once this kind of flour is left for a long time, it is easy to have insects, and it is also the kind of small black worm, I don't know if you can eat it when there are small black worms in the flour?

Can't eat. There are small black insects growing in the flour, called red grain thieves, commonly known as "cows", it can parasitize on edible fungi, corn, wheat, rice, sorghum, oilseeds, dried fruits, beans, Chinese herbal medicines, raw medicinal materials, ginger, dried fish, dried meat, leather, silkworm cocoons, tobacco and other things, the common harm object is flour, and the insect has stinky glands, can secrete odorous liquid, so that the flour has a musty smell, and its secretions also contain carcinogen benzoquinone, if there are such insects in the stored flour, for the sake of health and safety period, It's better not to eat.

What to do if there are small black worms in the flour.

1. Remove bugs.

First, the flour is exposed to the sun to destroy some bacteria and drive away insects. If the weather is bad, you can use a screen with dense holes to screen out insects.

2. Secondary use.

Although the flour that has grown worms can no longer be eaten, it also has the function of cleaning and removing grease stains, and can be used to clean faucets, remove carpet stains, clean greasy dishes, stoves, clean kitchen screens, etc.

If you use it to clean the kitchen screen, you can fill 100 grams of flour in the basin, add water to make a thin batter, and then brush it on both sides of the screen while it is hot, after 10 minutes, brush it several times with a brush, and then rinse it with water, and the greasy on the screen will be brushed clean.

How to preserve flour from mold and insects.

1. Garlic method.

The special taste of garlic is also very useful for insects, you can put garlic in flour to avoid flour worms, however, don't put too much, otherwise the food can easily bring these special flavors.

2. Regular drying method.

Flour moldy insects are mainly because the storage environment is too humid, resulting in an increase in the moisture content of the flour, which is conducive to the reproduction of insects, as long as the water content of the flour is controlled at 12%-13%, there will be no insects, so when storing the flour, you can often open the packaging bag of the flour to see if the flour is clumped and damp, once it is found that the moisture content of the finished product exceeds the upper limit, it should be dried in time or placed in the 55-60 dryer for baking.

Note. In addition to moisture-proof flour, it is also necessary to do a good job of ventilation, room temperature, environmental cleaning, and placing it in plastic bags or sealed containers to avoid odor, etc., if the temperature is too high, it will also shorten the shelf life of the flour, because the high temperature can speed up the maturity of the flour, so that the flour produces peculiar smell, and the quality is reduced, and the ideal temperature for its storage is 18-24.

How long does flour last.

6-8 months.

Generally, the time of preserving flour is subject to the shelf life marked on the package, usually this time is about 6-8 months, such as the flour that has been opened, it should be eaten as soon as possible to avoid insects and mold, but when it is found that there are small insects or rancid smell in the flour, do not continue to eat, such flour has health risks.

There are two reasons why flour produces black bugs:

It is the wheat raw material itself that contains insect eggs, or the eggs of insects in the equipment when the wheat is ground into flour, although the sieving of the flour mill can remove most of the live insects, but it is difficult to remove the eggs with a smaller volume;

Another reason may be improper storage, and the flour is also easy to produce black bugs when left in a humid environment for a long time.

How to remove the small black worm that is raw in the flour

Sieving method:Put the flour in a cool and ventilated place, let the insects crawl out slowly, and then sieve, remove the insects in the flour with a basket made of bamboo or wicker, or sieve with a sieve made of bamboo strips, and then spread the flour in a cool and ventilated place to dry to remove the insects;

Freezing method:If the flour insects are not serious, you can freeze the flour with the bag for 24 hours, and then take it out, at this time, the black insects inside are frozen to death and red and black, which is easier to sieve out.

The most likely occurrence of flour insects is that the storage conditions are too humid and unventilated, which is the most susceptible cause of insects caused by environmental factors.

Once black worms grow in flour, it means that the flour is no longer edible. The black bug that grows in flour is the red grain thief, commonly known as cow, which is the more common bug in flour. This insect grows stinky glands, which can secrete odorous liquid, which makes the flour have a musty smell, and its secretion also contains the carcinogen benzoquinone, so it is recommended to dispose of the flour with black bugs directly.

If the growth of small black worms in the flour is relatively light, you can first expose the flour to the sun, use ultraviolet rays to eliminate some of the insects in the flour, and then use a sieve to sift out the black worms and eggs.

If the flour worm situation is very serious and needs to be disposed of in time, the flour can also be reused. Flour has a strong effect of cleaning and removing grease stains, even if there are small insects growing on it, it will not affect the effect of flour, so flour can be used to clean faucets, remove carpet stains, wash greasy dishes, stoves, clean kitchen screens, etc.

When remembering the screen, you can first fill 100 grams of flour in the basin, add water and mix it into a thin batter, apply it on both sides of the screen, wait for 10 minutes, brush it several times with a brush, and then rinse with water to remove the oil stains on the screen.

Under normal circumstances, flour can only be stored for about 6-8 months, and the flour that has been opened needs to be eaten as soon as possible to avoid insects and mold.

Pay attention to things: Sichuan pepper is a seasoning in our daily life, not only can add a lot of flavor to our dishes, in fact, Sichuan pepper has many other uses. Due to the special smell in peppercorns, we can take advantage of this to preserve the flour. Flour insects are very sensitive to special odors, and the smell emitted by the pepper itself is just enough to repel the flour insects.

Therefore, we can prepare a small handful of peppercorns, put them in a gauze bag, and then seal the cloth bag tightly and put it in the flour, so that we can prevent the flour from growing insects.

Flour with black bugs can not be eaten.

There are small black insects growing in the flour, called red grain thieves, commonly known as "cows", it can parasitize on edible fungi, corn, wheat, rice, sorghum, oilseeds, dried fruits, beans, Chinese medicinal materials, raw medicinal materials, ginger, dried fish, dried meat, leather, silkworm cocoons, tobacco and other things, the common harm object is flour.

Precautions for flour storage:

1. Well-ventilated flour has a respiration effect, so it is important to maintain air circulation.

2。The moisture content of the flour will change with the humidity of the environment, and the higher the humidity, the greater the moisture content of the flour, and the easier it is to agglomerate. Therefore, the ideal humidity should be between 60% and 70%.

3。The right temperature: The ideal storage temperature for flour should be 18t 241.

4。Keeping the environment clean reduces the growth of pests and microorganisms, thereby reducing the chance of flour contamination.

5。The old and new flour is easy to grow insects after being stored for a long time, so the flour should be stored less and bought frequently, so as not to breed insect eggs on the aged noodles in the lower part of the noodle tank due to too long storage.

1. It is not recommended to eat flour with black bugs.

2. The small black worm that grows in the flour is called the red grain thief, commonly known as "cow", it can parasitize on edible fungi, corn, wheat, rice, sorghum, oilseeds, dried fruits, beans, Chinese herbal medicines, raw medicinal materials, ginger, dried fish, dried meat, leather, silkworm cocoons, tobacco leaves and other things, the common harm object is flour, and the insect has stinky glands, can secrete odorous liquid, so that the flour has a musty smell, and its secretions also contain carcinogen benzoquinone, if there are such insects in the stored flour, for health and safety period, It's better not to eat.
