Inspection: There are anti-counterfeiting trademarks and anti-counterfeiting codes on the packaging of real salt. The public can know the authenticity of the purchased salt by calling.

Second, look: there are folds on both sides of the packaging bag in fake salt, but there is no real salt packaging; The seal in the middle of the back of fake salt bag is glued, and the vertical glue in the middle of real salt bag is sealed.

Three tests: it is also easy to distinguish true and false salt with iodized salt rapid detection solution. Iodized salt will turn blue after dropping the test solution, while fake salt without iodized salt will not change color.

Question 4: The retail price of regular iodized salt is 1.3 yuan, while fake salt is generally 1 yuan or lower.

5. Look at the packaging. Refined iodized salt is packed in polyethylene plastic, printed with the words iodized, and marked with the production unit and factory date. The handwriting is clear, the bag is of good quality, beautifully printed and tightly sealed. Counterfeit iodized salt has blurred handwriting and rough packaging.

6. Look at the color. The appearance of refined iodized salt is white; The appearance of counterfeit iodized salt is light yellow or dark black, and it is easy to get wet without drying.

7. Pinch with your hands, smell with your nose and taste with your mouth. Refined iodized salt has loose fingers, uniform particles, no peculiar smell and pure salty taste; False iodized salt is easy to disperse when rubbed by hand. It tastes bitter and astringent, and it also smells of ammonia.

8. This is a color test. Sprinkle iodized salt on sliced potatoes. If it is blue, it is true iodized salt. Such as light blue, no blue, non-iodized salt.
