Introduction: Salt is an indispensable condiment in our daily life and a commodity strictly managed by the state. Recently, some lawless elements have committed crimes for profit. Edible fake salt processed with industrial salt flows into the market, and these heavy metals in fake salt exceed the standard, which is extremely harmful to human body. So how do ordinary consumers distinguish real salt from fake salt? Identification diagram of fake salt and real salt

See if the sealing line is hot-cut, and the hot-cut is true. The sealing parts at both ends of the fake salt packaging bag are relatively flat and serrated, which belongs to cold cut; The real salt is automatically heat-packaged, and there are traces of softening and unevenness at the incision.

second, check whether there are creases on both sides, and if there are no marks, it is true. Fake salt is usually printed in a packaging bag first, and then the salt is bagged. The packaging bags are often stacked before bagging, which will lead to indentation on both sides; The real salt is a one-time molding package, and there will be no creases on both sides.

thirdly, check whether the anti-counterfeiting marks on the back of the package are consistent. If the fake edible salt in the same batch is labeled by hand, the position of the anti-counterfeiting mark may be inconsistent; The salt sold by the salt company and the anti-counterfeiting signs are all made by machine.

Secondly, it depends on the color and texture of the salt.

The real salt has no impurities, and the particles are fine and even, and it is transparent or translucent, while the fake salt has more impurities, and its color is gray and dark, and some are even yellowish brown.

There is also the simplest way to identify the true and false salt

Slice the potatoes, and sprinkle the bought salt evenly on the potato chips. After a few minutes, the ones that don't turn blue and purple are the ones that are not iodized. fake salt.

In addition to ordinary refined iodized salt, there are many kinds of edible salt in life. What is the difference between them? How should we choose?

iodized salt

the most common and commonly used edible salt. In order to prevent iodine deficiency, a certain dose of potassium iodide and potassium sulfate was added to common salt to make iodized salt. In general, all kinds of people can eat it.

However, iodized salt is easy to be oxidized and decomposed, which makes iodine ineffective. Therefore, iodized salt should be stored in a colored sealed container in a cool and dry place, so don't buy too much at a time. Because iodized salt will decompose and volatilize when it meets high temperature, you should wait until the dishes are cooked before putting salt in cooking, and try to avoid using iodized salt to start the pot, stew and cook for a long time, so as to reduce the loss of iodine.

refined salt

, also known as fine salt, refers to the salt that is crystallized again after impurities are removed from the original salt, but many trace elements in the original salt are also removed after these processes. Can be use as a common seasoning in daily life, but has no other health care effect.

snowflake salt

belongs to a kind of sea salt. It takes seawater as raw material and collects a variety of trace elements necessary for human body in seawater. Compared with other types of salt, sea salt contains more trace elements and is more easily absorbed by the human body. People with poor gastrointestinal absorption can eat more snowflake salt.

low sodium salt

the purity of sodium chloride in traditional salt is over 95%, while potassium chloride is used to replace part of sodium chloride in low sodium salt, and the sodium content is only 65% ~ 7%, which can effectively reduce the risk of cardiovascular diseases such as hypertension and heart disease. The contents of magnesium and potassium in low-sodium salt have increased. Because potassium is also one of the essential trace elements for human body, a proper amount of potassium is helpful to lower blood pressure. Low-sodium salt is mainly for special people who need to limit sodium salt, such as kidney disease, hypertension and heart disease.

Adding calcium salt, iron salt, zinc salt and selenium salt in proportion to iodized salt is suitable for people who need to supplement these trace elements. For example, adding iron salt is suitable for infants, women and middle-aged and elderly people, and adding selenium salt is suitable for middle-aged and elderly people and patients with cardiovascular diseases.

riboflavin salt

Vitamin B2 is added to common table salt, which is suitable for long-term vegetarians and supplemented appropriately.
