1. Edible salt contains iodine and has undergone strict inspection before leaving the factory. All indicators meet the national standards for edible salt. From the appearance, it appears white, in a fine sand like shape, with very little water content. When kneaded by hand, there is no sense of coagulation.
2. Industrial salt does not contain iodine, has a dark color, and is mostly granular in shape with high moisture content. Industrial well salt has a similar appearance to edible salt, but it does not contain iodine due to its toxic substances.
Industrial salt:
Industrial salt is mainly used in alkali production, boiler soft water, dyes, soap and laundry detergent, feed processing, and other fields, but when it enters the food industry, its harm is not small. Due to its presence of nitrite and other components, people may experience chronic poisoning after consuming it. Generally speaking, ingesting only 0.2 to 0.5 grams of nitrite can cause poisoning; Consuming 3 grams of nitrite can cause death. Meanwhile, industrial salt does not contain iodine, and severe iodine deficiency in the human body can lead to the occurrence of diseases.
Industrial salt is one of the most basic raw materials in the chemical industry, referring to raw salt. Raw salt can be divided into lake salt, well salt, and sea salt. Because the seawater in sea salt dissolves multiple elements, the industrial value of sea salt is relatively higher, while its edible value is lower. Industrial salt has a wide range of industrial applications and is one of the most basic raw materials in the chemical industry, known as the mother of chemical industry.
The main products in the basic chemical industry, such as hydrochloric acid, caustic soda, soda ash, ammonium chloride, chlorine gas, etc., are mainly produced from industrial salt as raw materials.
Industrial salt is a chemical raw material that cannot be used. Once ingested, it can cause symptoms of poisoning. Patients may experience dizziness, tinnitus, nausea, vomiting, diarrhea, and in severe cases, difficulty breathing, coma, and even convulsions throughout the body. Edible salt, on the other hand, is purified and processed from seawater. It is not only a seasoning, but also has anti-inflammatory and bactericidal effects. For example, in cases of gingivitis caused by excessive heat, salt can be used to rinse the mouth, which has the effect of reducing inflammation.
