How to distinguish the authenticity of salt How to know the authenticity of salt

One of the most obvious aspects of fake salt is that fake salt packaging bags often have creases, which are traces of hand-packing.

To argue for fake salt, we must first look at the packaging bag:

1. See if the sealing line is a hot incision, and the hot incision is true. The sealing at both ends of the fake salt package is relatively flat, jagged, and belongs to the cold incision; And the real table salt is automatically heat-packed, and there are traces of softening and unevenness at the incision.

2. It is to see whether there are creases on both sides, and no creases are true. Fake salt is generally printed in the packaging bag first, and then the salt is bagged, and the packaging bag is often stacked and placed before bagging, which will lead to indentations on both sides; Real table salt, on the other hand, is packaged in a one-time mold and does not appear creases on both sides.

3. See whether the position of the anti-counterfeiting mark on the back of the package is consistent. For the same batch of fake table salt, if it is manually labeled, the position of the anti-counterfeiting mark may be inconsistent; The anti-counterfeiting marks of the salt sold by the salt company are machine-printed.

One is to identify from the outer packaging. The outer bag of real salt is thicker and softer to the touch, whereas the outer bag of fake salt is brittle and thin. Fake salt bags have obvious creases on both sides, while real salt bags have no creases.

Look at the back of the packaging bag, the number of each package of real salt is different, and if the number is the same, the whole batch of salt is fake salt; The anti-counterfeiting logo of each package of real salt is fixed in the same position.

The second is to look at the sealing of the packaging bag. The mouth of the packaging bag of real salt is sealed neatly and is difficult to tear, and the seal of fake salt is sealed with an electric soldering iron, which is easy to deform and tear. The real salt is filled into a cylindrical plastic film on the assembly line, and then cut and encapsulated, and the upper and lower seals will not be jagged; The packaging bag of fake salt is a disposable molded packaging bag, and the seal is jagged.

The third is to look at the salt quality. Real salt is relatively clean, with high whiteness and no impurities. The whiteness of the fake salt is poor, and there are impurities, and in terms of quantity, the fake salt generally does not meet the standard.

Fourth, chemical methodsIn addition to NaCl, the components in the real salt also contain iodine, there is no iodine in the fake salt, tested with starch solution, according to the principle of starch solution turning blue when encountering iodine, in addition, the difference between industrial salt and edible salt is that industrial salt contains impurities such as magnesium chloride, which is easy to absorb moisture in the air and becomes damp, and can be observed for a long time to distinguish between industrial salt and edible salt, and can also add clarified lime water to distinguish industrial salt from salt, and industrial salt added to clarified lime water will produce sediment.

There are more and more varieties of salt on the market, and how to judge the authenticity is the key!

It's hard to tell if salt is real or fake, so come and learn this trick.

1. From the perspective of the outer packaging of table salt, the outer packaging of real salt is relatively thick, and it has a soft feeling when you touch it carefully; The outer packaging of fake salt is relatively thin and feels brittle to the touch. The code for each package of real salt is different, and the code for fake salt is likely to be the same;

2. From the point of view of the sealing of the salt, the packaging and sealing of the real salt is relatively neat, and when carefully touched by hand, there is a feeling of unevenness; The outer packaging seal of fake salt is relatively rough, and the feeling of unevenness is not obvious;

3. The real salt is fine sand, white in color, no agglomeration, and not easy to absorb water; The fake salt is granular, contains impurities, and easily absorbs water;

4. The date on the small package of real salt is not very clear, if you wipe it hard, you can wipe it off; The date on the fake salt is very clear, not easy to erase, and it is very beautiful from the outside;

5. Real salt contains iodine, you can take a small amount of starch solution, the real salt will turn blue when it encounters the starch solution, but the fake salt will not;

6. Identify from the anti-counterfeiting mark on the outer packaging, the anti-counterfeiting mark of real salt will change to different colors after changing the direction and angle; No matter how the direction and angle of the fake salt anti-counterfeiting sign are changed, the color will not change.

Salt occupies an important place in our daily life and is an indispensable condiment in every family. But now there are some criminals on the market who use fake salt instead of real salt, and people who do not know the truth will have a negative impact on their bodies if they eat fake salt. So what methods can we use to tell if the salt we are buying is real or fake?

1. Look at the packaging: the edge of the fake salt packaging bag is serrated and angular, the cutting is obvious, and there are creases on the side; The real salt packaging is sleek, and the sealing adopts thermal fusing technology, and there are no obvious sharp serrations of fake bags.

2. Look at the anti-counterfeiting mark: the anti-counterfeiting mark of real salt has a clear hollow pattern and words, which is not easy to erase; The anti-counterfeiting mark and production date of fake salt are blurry and easy to erase.

3. Look at the inkjet code: the real salt inkjet code is unique and will not be repeated; The inkjet codes of fake salt are all printed in advance, and they are all the same, and there will be duplicates, similar to the "serial number" of counterfeit money.

4. Look at the production date: the production date printed on the packaging bag of fake salt is basically fixed in the same position. The production date and location of real salt will be printed in different positions due to mechanical movement.

1. The color of salt is generally white or dark gray. Usually the processed salt is white, and the unprocessed salt is dark gray, so when you choose, look at the color. If the white is uneven, it is false.

2. Really good salt is dry, dry, and has no wetting feeling. And if the fake salt, because it contains other water-absorbing factors, it is easy to regurgitate, if you find that its moisture content is large, not dry, it is not recommended to buy bulk.

3. Grab the salt, put it in the palm of your hand, and feel it, generally, the refined salt will have a loose feeling, and the particles will be uniform, and there will be no large or broken grains. And if there are lumps, or other debris, it is false salt.

4. Take a few drops of salt, feed them to your mouth, and feel the taste. Ordinary refined salt has no taste other than saltiness. If the salt you taste is astringent or bitter, it is fake salt.

5. In terms of packaging, we must be optimistic, refined and fine, its packaging is neat, and all the production marks and substances it needs are clear, while the fake ones are rough and the ingredients are not even written.

6. Iodized salt, there will be fluorescent iodized words on it, and it cannot be rubbed off by hand. And if it is fake salt, although iodized salt is also written, but if you rub it by hand, it will fade or the handwriting will fall off.
