How to identify fake salt and real salt

Salt is an indispensable daily necessity in people's daily life. The salt consumed by many people is mainly well salt and sea salt. For such a daily necessity, there must be unscrupulous businessmen who counterfeit it. So what indicators and methods should we use in our daily life to distinguish between fake salt and real salt? Here are some methods that may work for you.

Four ways to distinguish real and fake salt

According to experts, industrial salt is mainly used in alkali production, boiler water softening, dyes, soaps and feed processing. Industrial salt contains more heavy metals and impurities that are harmful to the human body. Long-term consumption can cause great damage to the liver and kidneys.

Generally speaking, regular edible salt is white in color and in the form of fine sand. It contains very little water and does not feel clumpy when kneaded with your hands. Industrial salt does not contain iodine, is gray in color, is mostly granular in appearance, and has a high water content. Industrial well salt looks similar to edible salt, contains toxic substances but does not contain iodine.

It is difficult to distinguish the authenticity of qualified iodized salt produced by salt companies and fake table salt processed from industrial salt. Once citizens find that the salt sold in some places is different from the regular salt produced by the salt company, they can ask experts to identify it and report it to the management department. In addition, experts say that the authenticity of table salt can be identified from the following four aspects.

1. Identify from the outer packaging. The outer packaging bag of real salt is thicker and feels softer to the touch, while the outer packaging bag of fake salt is brittle and very thin. If the numbers are the same, the entire batch of salt is fake salt.

2. Check the seal of the packaging bag. The packaging bag of fake salt is a disposable molded packaging bag, and the seal is sealed with an electric soldering iron. It is serrated and easy to deform and tear. The edges of real iodized salt bags are relatively regular, with equal width at both ends, but fake iodized salt bags often have one end that is longer.

3. Look at the salt quality. Real salt is relatively clean, has a high whiteness, and is free of impurities. Fake salt has poor whiteness and contains impurities, and its weight generally does not meet the standards.

4. Chemical method. Real salt contains iodine in its composition. There is no iodine in fake salt. It can be identified by testing it with starch solution, based on the principle that starch solution turns blue when it comes into contact with iodine. If there is a color change, it means it is qualified iodized salt.

Judging from the anti-counterfeiting labels: the labels on the real iodized salt bags are neatly pasted in the same position, while the labels on the fake iodized salt bags are obviously not pasted in a standardized manner.

From the origin point of view: because the sales of salt products are strictly regional, Sichuan region generally only sells various types of iodized salt produced by Zigong Jiuda Salt Company.

Verification Method

There is a very convenient way to identify the authenticity of salt. Sprinkle salt on freshly cut sweet potatoes or potatoes. If the cut surface turns blue, it is iodized salt. Otherwise, it is fake.
