Why do bugs grow in flour? Why does flour have worms

Bugs grow in flour because the flour gets damp and attracts eggs. These eggs begin to hatch into worms at the right temperature and humidity and grow in flour. In addition, wheat, the raw material for flour, can also be susceptible to insect infestation during transportation or storage.

1. Flour is rich in nutrients, providing various nutrients such as starch, protein, fat, cellulose, vitamins and other nutrients needed by insects.

2. In the process of processing, storage, transportation and sales of flour, it is easy to be infected with pests, and many flours also have insect eggs.

3. When the temperature is right, the stored grain pests begin to grow and reproduce.

Flour is a powder made from wheat milling. According to the amount of protein content in flour, it can be divided into high-gluten flour.

All-purpose flour, low-gluten flour.

and gluten-free flour. Flour is nutritious and also has therapeutic effects, flour is rich in protein and carbohydrates.

Vitamins and minerals such as calcium, iron, phosphorus, potassium, magnesium, etc., have the effect of nourishing the heart and kidneys, strengthening the spleen and intestines, removing heat and quenching thirst. The therapeutic effect of traditional Chinese medicine on flour can be summarized as follows: nourishing the heart, benefiting the kidneys, and strengthening the blood, and strengthening the spleen.

Flour (wheat flour.

It is a staple food in most of northern China. There are many varieties of foods made from flour, with a variety of flavors. But flour is not well preserved and prone to insects, so how to preserve it without worms? Let's take a look.

There are two main ways for flour insects: 1. The eggs brought in the wheat are mixed into the flour when the flour is grinded, and will develop into adults when the temperature and humidity are suitable; 2. During storage, the seal is not tight, and it is contaminated by pests.

Cloth bag flour absorbs moisture, it is easy to get insects, it is best to use a plastic bag, be sure to tie the mouth tightly. Once the flour has insects, you can spread the noodles in a cool, dry and ventilated place to disperse the insects; If the flour is damp again, it can be exposed to the sun, mainly to dry the flour. Then the flour of the raw worms is divided into small plastic bags and placed in the refrigerator freezer for 10 hours, which can not only kill the adult worms, but also kill the eggs, and sieve out the dead worms after taking them out.

If there are small insects in the flour, two reasons can be considered, one is because the wheat raw material itself contains insect eggs or the presence of insect eggs in the equipment when the wheat is ground into flour, and the other important reason may be improper storage, and the flour is placed in a humid environment, which is also easy to make the flour grow worms.

It is possible that there are insect eggs in the raw wheat, which causes insects to grow after being powdered, and there are also insects when the flour is infected with eggs when it is stored.

There are more than 40 kinds of stored grain pests, which often appear in flour, and also look at the infected pests**, but there are generally the following three categories.

1. Lepidoptera (moths). 2. Coleoptera (beetle), red grain thief, miscellaneous grain thief, corn elephant, sawgrain thief, large grain thief, spine spine, tobacco beetle, black beetle, rice elephant, mealworm, black fungus, etc.

3. Mites.

The first reason may be the presence of eggs in raw wheat. In the process of grinding wheat into flour, there is a collision process, which can make the adults in the wheat be crushed and killed. However, the eggs carried by the wheat (mainly in the embryo) do not die, and they will then enter the flour and hatch into larvae under the right conditions.

The main reason for the insects in the flour is that the flour raw materials contain insect eggs, the processing plant equipment is not clean, the storage is improper, the raw wheat is stored and transported in the process of insects, and the processed factory equipment is mixed into the flour after processing, and the old corners of the processing plant equipment are easy to grow insects, and the flour is stored in the flour when it is damp and not sealed, and it is easy to be polluted by pests.

Flour insects are insects that contain eggs in raw wheat, which usually enter the wheat during processing, storage, and transportation.

Collectively known as grain pests, they can be divided into two categories: moths and beetles, small in size and hidden, and the eggs in the flour raw materials will grow into pests when the ambient temperature and humidity are suitable.

The second reason may be that there are insect sources in warehouses, supermarkets, kitchens, etc., which lay eggs in the flour, making the flour "wormed". For example, if other food products in the supermarket have worms, the adults may go to the flour house next to them to "string the door", causing the flour to become worms.

The third reason may be that the flour was infected with insect eggs during transportation. However, this probability is relatively small, because now flour is mainly transported by cold chain, and under the action of low temperature, it is not easy for insect eggs to survive.

It's okay to eat the larvae and eggs.

Sometimes, just after eating a bowl of hand-rolled noodles made by myself, I found a bug at the bottom of the bowl. So I began to worry: will it be okay to eat the larvae and invisible eggs in the flour?

Experts say there is no need to worry about this situation, because the eggs do not carry bacteria and are harmless to humans, as do the larvae.

If the flour is put for too long, in a high temperature and humid environment, it is easy to breed some hard-shell insects that often appear in the flour, that is, beetles, it is recommended that you put some small cloth bags of garlic and peppercorns in the flour, and buy less every time you buy, and then buy after eating, so that it is not easy to have insects.

Hello, if the flour is left for too long, in a humid environment, there will be a lot of fungi that act frequently and then produce small insects. So take the flour out to dry often.

Almost all of the grain storage pests that breed flour are common, and more than 40 species commonly grow in flour, which can be divided into four categories, beetles (Coleoptera) grain storage pests, corn elephants, red grain thieves, miscellaneous grain thieves, saw grain thieves, grain beetles, and tobacco beetles.

, Herb A, Rice Elephant, Great Valley Thief, Grain Elephant, Mealworm, Mealworm.

, black fungus, etc.

Moths Lepidoptera), wheat moths, Indian grain moths, little grain moths, pink spotted borers, etc.

Rodents, book lice.

Mites, people are also listed in the insects, and the damage is also very serious. dust mites, etc.

1. Flour insects are because the flour is damp, which will cause the eggs in the grain to begin to grow slowly, and the insects we see appear, if you want the flour to not have insects, you must store it in a dry place.

2. Flour is one of our grains, this kind of food can make a lot of food, such as buns, fritters, steamed buns, etc., these foods are made of flour, it can be said that the role of flour is really special.

3. In daily life, if we can't finish the flour we buy home, we can put some star anise in the flour at this time, and then put the flour in a ventilated and dry place, which can be stored for a long time, and it can also make the flour free of insects.

4. The raw material of flour is wheat, wheat has the possibility of growing insects during transportation or storage, and the factory specializing in the production of flour is not necessarily very clean.

5. Therefore, when storing flour, it is best to keep the environment dry and clean, and do not leave it for too long, and eat it in time, so as to avoid insects.
