How to identify whether wheat flour noodles are insects

Sprinkle a thin layer of flour sample on black paper, carefully observe for mold, agglomeration, insects and impurities, etc., and then twist it by hand to test the feel. When pinched by hand, there is a coarse grain, indicating that there are insects or impurities.

Prevent wheat flour.

The way to get insects:

1. Good ventilation Flour has a respiration effect.

Therefore, it is necessary to circulate the air so that the flour can be used.

2. Humidity and dryness Flour will change its water content according to the temperature and humidity of the environment.

The higher the humidity, the higher the moisture content of the flour, which is easy to clump. The lower the humidity, the lower the moisture content of the flour. The ideal humidity is between 60%-70%.

3. The right temperature The temperature of storage will affect the aging time of the flour, the higher the temperature, the faster the aging. But the temperature also shortens the shelf life of the flour.

The ideal temperature for flour storage is 18 -24.

4. Clean environment A clean environment can reduce the breeding of pests and microorganisms, thereby reducing the chance of flour contamination. 5. No peculiar smell Flour is a material that will absorb and store odors in the air, so there can be no peculiar smell in the surrounding environment where flour is stored.

6. Off the wall and off the ground In order to have good ventilation, reduce moisture, reduce pest pollution and legal requirements, this is necessary. Pallet boards should be made of plastic products, such as wood products, should be careful of wood thorns, pollution.

7. First-in-first-out ensures the stability of flour and reduces the expiration of flour caused by man-made.

8. Regular cleaning to reduce the breeding of pests, thereby reducing the chance of flour contamination and packaging damage.

1. The simplest is to press the flour into a smooth surface with a smooth surface, and there are traces of insects on the surface that can swell with pests.

2. Use a sieve of more than 60 mesh (in fact, a small basket and sieve can be used) to dry the flour, and insects and molts can be presented on it.

3. Fresh flour has a clear fragrance, and flour with insects or moisture has a musty smell and clumping. If there are a large number of insects, there are other strange smells.

You can smell its smell, and generally those with insects will have a musty smell or damp smell.

Also see if it's clumped.

Sieve with a fine sieve to know.
