Table salt

salt refers to sea salt, well salt, mineral salt, lake salt, soil salt, etc. from different sources. Their main component is sodium chloride, and the state stipulates that the sodium chloride content of well salt and mineral salt shall not be less than 95%. Salt contains barium salt, chloride, magnesium, lead, arsenic, zinc, sulfate and other impurities. We stipulate that the barium content should not exceed 20 mg/kg. Too much magnesium and calcium in salt can make salt with bitter taste, and too high fluorine can also cause poisoning. In recent years, many experiments have confirmed that there is a certain relationship between salt intake and the incidence of hypertension. Excessive salt intake in the diet can cause hypertension. The World Health Organization (WHO) recommends that people consume less than 5g of salt per day to prevent coronary heart disease and hypertension. Our country stipulates that the daily intake of 7g salt for adults can meet the needs of the body for sodium.

Salt is a must for every family. People cannot but eat salt. Although we advocate eating less salt, it is for health. However, large quantities of industrial salt warned that the processing and packaging had become "edible salt", which unscrupulous traders used to make huge profits. This salt is extremely harmful. Salt with iodine deficiency will affect human metabolism, damage the nervous system and intellectual development. The advantages of

salt packaging are: prevention of pollution, convenient storage and transportation (not decomposed during shelf life, with certain strength and shape), non-toxic, compatible with salt, no interaction and other aspects. Starting with materials suitable for sodium chloride and iodine, it must comply with food packaging safety regulations. Moreover, bag packaging is the main packaging form for domestic salt enterprises to reduce labor costs and improve production efficiency.
