Four ways to identify real and fake salt: First check: There is an anti-counterfeiting trademark and anti-counterfeiting code on the packaging of real salt. Citizens only need to make a phone call to know whether the salt they buy is real or fake. Second look: There are wrinkles on both sides of the fake salt packaging bag, but there are no wrinkles on the real salt packaging. The middle seal on the back of the fake salt package is glued shut, while the vertical glue on the middle seal of the real salt package is sealed. . Three tests: Using the iodized salt rapid test solution, it is also easy to distinguish between real and fake salt. Iodized salt will turn blue after dripping with the test solution, while fake salt without iodization will not change color. Four questions: The retail price of regular iodized salt is 1.3 yuan, while fake salt is generally 1 yuan or less. 5. Look at the packaging. Refined iodized salt is packaged in polyethylene plastic, with the words iodized printed on it, and marked with the production unit and date of manufacture. The writing is clear, the bag is of high quality, the printing is exquisite, and the sealing is tight and neat; the counterfeit iodized salt has blurred writing and rough packaging. 6. Look at the color. Refined iodized salt has a white appearance; fake iodized salt has a light yellow or dark black appearance, is not dry, and is susceptible to moisture. 7. Knead it with your hands, smell it with your nose, and taste it with your mouth. Refined iodized salt is loosely kneaded by hand, with uniform particles, no odor, and pure salty taste; fake iodized salt is kneaded into balls by hand and is easy to disperse. It tastes bitter in the mouth and smells like ammonia. 8. It is a color development test. Sprinkle iodized salt on the cut surface of the cut potato. If it shows blue color, it is true iodized salt; if the blue color is light, but there is no blue color, it is not iodized salt.
