How to distinguish the authenticity of table salt, and how to distinguish the authenticity of table

1. Look at the color.

Refined iodized salt has a white appearance. The appearance of counterfeit iodized salt is different, or light yellow, or dark black, not dry enough, and easy to moisture.

2. Look at the anti-counterfeiting label.

Refined iodized salt has a laser anti-counterfeiting mark, while counterfeit iodized salt does not.

3. By feel.

Refined iodized salt is loosely grasped and pinched by hand, and the particles are uniform. Fake iodized salt is kneaded into a ball by hand, which is not easy to disperse.

4. Look at the packaging.

Polyethylene plastic packaging bag for refined iodized salt, printed with the words "iodized" or "iodized salt", and marked with the production unit and factory date, the handwriting is clear, the hand can not be rubbed off, the bag is thick or coated, and the seal is neat and tight. The words "iodized" and "iodized salt" printed on the fake iodized salt are blurred, and can even be erased by hand, and the packaging is simple and not tight, and the sealing is not neat.

5. Smell the smell.

Refined iodized salt has no odor and no odor or other peculiar smell. Pseudo-iodized salt is mixed with industrial iodine-containing waste residue and ammonium nitrate and other ammonium-containing substances, so it has ammonia smell and other odors.

6. Taste with your mouth.

Refined iodized salt is pure salt, and false iodized salt is salty with bitter taste.

7. Color development test.

Sprinkle salt on the cut surface of the potato, if it shows blue, it is true iodized salt, if it does not react blue, it is non-iodized salt.

The following aspects can help identify whether it is counterfeit salt: 1. Packaging quality: Generally, the packaging quality of counterfeit salt is poor, especially at the sealing place; 2. Running number:

Generally, the counterfeit salt is the same serial number; 3. Anti-counterfeiting mark: Generally, counterfeit salt does not have anti-counterfeiting mark or the anti-counterfeiting mark is rough. [/

In order to protect the health and food safety of the people and promote the healthy development of edible salt products, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China organized national supervision and random inspection of the quality of edible salt products. A total of 107 kinds of products produced by 79 enterprises in 17 provinces, autonomous regions and municipalities directly under the central government, including Beijing, Hebei, Shanxi, Inner Mongolia, Sichuan, Hubei, Hunan, Guangxi, Zhejiang, Fujian, Jiangxi, Jilin, Henan, Anhui, Chongqing, Shaanxi and Gansu, were randomly inspected, and 104 kinds were qualified, and the product sampling pass rate was.

The results of this random inspection show that the continuous national supervision and random inspection has promoted the improvement of the overall quality level of edible salt products. The main problems found in the spot check are the non-standard labeling of individual enterprises.

In view of the quality problems found in this random inspection, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China instructed the local quality and technical supervision departments to deal with and rectify the unqualified enterprises in this random inspection in accordance with the provisions of relevant laws and regulations such as the Product Quality Law. At the same time, a number of products with better product quality and their production enterprises in random inspections were announced to guide consumption. The General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China will continue to track and spot check the quality of such products, promote the continuous improvement of the overall quality level of products in the edible salt industry, and create a safe and satisfactory consumption environment for consumers.

The quality of edible salt products is supervised and inspected by the state, and some products with better quality and their list of enterprises.

Serial No. Company Name Product Name Trademark Specification Date of Manufacture.

1. Hangzhou Lanhaixing Salt Products Factory Calcium Fortified Nutrients Lanhaixing 500g Bag 2005-08-19

2. Jiangxi Salt Mine Co., Ltd. Refined Salt Jinggang 50kg bag 2005-12-21

3. Beijing Huade iodized salt distribution center, refined salt, Jingjing, 1kg bag, 2005-12-21

Note: Rankings are in no particular order.

First look at the packaging of edible salt, the clarity of the ink, and the anti-counterfeiting logo, and then look at his packaging port, which is different in various places.

Finally, the quality of salt is not easy for you to judge, because the iodine content is used with professional reagents, because it is iodic acid ja not pure iodine.

A special iodine content test solution is required.

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

A look at the color: generally high-grade oil color is light, low-grade color is dark (except sesame oil), and the color of the oil is also slightly different from the same grade oil color because of its different varieties. Second, look at transparency:

Generally, high-grade oil has good transparency and no turbidity. Third, look at whether there is sediment: high-grade oil has no precipitation and suspended solids, and the viscosity is small.

Fourth, look at whether there is a stratification phenomenon: if there is stratification, it is likely to be adulterated mixed oil (sesame oil is more adulterated). Five smells:

Each variety of oil has its normal unique smell without sour odor. Six checks: for small packages of oil to carefully check its trademark, pay special attention to the shelf life and factory date, no factory name, no factory address, no quality standard code, do not pay special attention.

Finally, consumers are reminded that when buying edible vegetable oil, in addition to considering the variety and flavor, they should also pay attention to health and safety, and give priority to edible vegetable oil with a higher degree of refining. Quality requirements and technical standardsThe technical indicators involved in edible vegetable oil mainly include color, 280 heating test, smoke point, acid value, peroxide value, carbonyl value, leaching oil solvent residue, aflatoxin B1, etc. Different varieties and grades of vegetable oil have their own quality standards.

In order to prevent the deterioration of edible oil, it is also necessary to choose a reasonable storage container. When there is more oil, you can choose a ceramic cylinder, and when there is less oil, you can choose a dark glass bottle that is opaque, and try to reduce the diameter of the container. After the oil is filled, the bottle mouth should be sealed to isolate the oil from the air and prevent the oxidation of the edible oil.

The storage container should be placed in a cool, dark and dry place with a low temperature.

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.

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 is no obvious sharp serration of the fake bag.

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.

Hello dear, I'm happy to answer for you: how to distinguish the real from the fake with edible salt? The answer is:

1.Identification of edible salt in small packages (500 grams): real small packages of table salt.

The pattern font of the qualified small package salt packaging bag is clear, the bag body feels thick and elastic, the gloss is good, the sealing is neat and standardized, the anti-counterfeiting sign laser light is strong, the back code is a bag and a group, and the digital bag is different. The iodized anti-counterfeiting mark is square, and the non-iodized salt anti-counterfeiting mark is round. The salt crystals in the bag are white in color and pure in salt.

Fake small package of salt: the pattern and font of the packaging bag are blurred, the bag feels thin and crisp and dry, the gloss is poor, the sealing is not standardized, the anti-counterfeiting sign is poor in laser light, dim, the back code number is all the same, and the outer packaging bag is marked with the word "iodization", in fact, it is industrial salt and inferior salt. The salt crystals in the bag are small and light yellow or dark black in appearance.

2.Identification of large packaging (50 kg) salt: real large packaging bag salt:

Printed with the words "exquisite iodized salt" in red, the production enterprise and factory address are clearly marked, and the bottom of the large packaging bag has the "Weiqun" brand anti-counterfeiting logo. Fake large packaging bags of salt (private salt): First, white, yellow, and green packaging bags are not labeled; the second is printed with blue or red English letters; The third is to use real packaging bags for secondary packaging, and the sealing is not standardized.
