Recently, the Beijing police teamed up with multiple provincial and municipal police to jointly crack down on a case of counterfeit salt production. The suspect sold industrial salt as edible salt and sold 20,000 tons of counterfeit salt. The amount involved was as high as RMB 20 million. .
The danger of eating fake salt
The main ingredient of salt is sodium chloride, and some of the iodized salt contains a small amount of potassium iodate. These are beneficial elements for humans. In the false salt, sodium chloride is often replaced with sodium nitrite. It can be used to enhance color, flavor, and sterilization. Therefore, false salt is generally used in industry.
Because sodium nitrite (NaNO2) is savory and very cheap, it is usually put in fake salt. However, sodium nitrite is poisonous, so it is generally used only in industry. However, these recently released pseudo-salts contain The composition of sodium nitrite, sodium nitrite is very toxic and can cause cancer!
Consumption of fake salt is very harmful, because false salt does not add iodine, it will lead to lack of iodine in the human body, gastrointestinal disorders, nervous system damage. If the body is iodine-deficient, lighter people will experience a loss of 10% to 20% of their intelligence, and severe cases will result in thin or dementia.
The appearance of industrial salt is very similar to that of salt, and the surface is delicate and white, but the composition is very good. Sodium nitrite is a toxic chronic carcinogen in the composition of industrial salt. The human body ingests sodium nitrite from 0.3g to 0.5g, which can cause poisoning. Excessive intake can lead to respiratory and circulatory failure and death. . Sodium nitrite is extremely harmful to human health and is prohibited from eating.
If you eat edible salt imbibed with industrial salt, the hazard is even greater. Dizziness, vomiting, diarrhea, general weakness, and other symptoms can occur. It is understood that industrial salt is mainly used in the production of alkali, boiler soft water, dyes, soap and detergent, feed processing, and other areas, and into the food industry, its harm is not small.
Four strokes to distinguish between true and false salt
According to experts, industrial salt is mainly used in the production of alkali, boiler soft water, dyes, soap and feed processing, etc. Industrial salt contains more heavy metals and impurities harmful to the human body. Long-term consumption of liver and kidney damage.
In general, regular salt is white, finely sanded, and has very little moisture, and there is no feeling of coagulation when kneading by hand. Industrial salt does not contain iodine, the color is dark, the shape is mostly granular, and the water content is large. The salt profile of industrial wells is similar to that of edible salt, but the toxic substances do not contain iodine.
It is difficult to distinguish between true and false salt produced by salt companies for the use of iodized salt and industrial salt. Once the public finds that there are places where the salt sold is different from the salt produced by the salt company, experts may be asked to identify it and report it to the management department. In addition, experts said that the true and false salt can be identified from the following four aspects.
First, identify from the packaging. The real salt bag is thicker and feels softer, while the fake salt bag is crispy and thin. With the same number, the entire batch of salt is a false salt.
Second, look at the seal of the bag. The false salt packaging bag is a one-time molding packaging bag. The sealing is sealed with electric iron and is serrated, easy to deform and easy to tear. The real iodized salt bag seal is more formal and the widths of both ends are equal, but false iodized salt bags tend to grow on one end.
Third, see the salt. True salt is clean, white, and free of impurities. The false salt has poor whiteness and impurities. In terms of weight, false salt generally does not meet the standard.
Fourth, chemical methods. True salt contains iodine. There is no iodine in the pseudo-salt. The starch solution test can be distinguished based on the principle that the starch solution can be changed to iodine blue. If there is a change in color, it means that it is a qualified iodized salt.
Judging from the anti-counterfeit labels: The labels on the real iodized salt bags are all affixed to the same place and the labels on the fake iodized salt bags are obviously not standardized.
From the perspective of origin: Because salt sales are strictly regional, Sichuan Province generally only sells various types of iodized salt produced by the company's Jiuda Salt Company.
Authentication method
There is a very convenient way to identify the true and false salt. Spread fresh salt on the freshly cut sweet potatoes or potatoes. Ivory salt is added to the cut blue, otherwise it is a counterfeit product.
