These products are made with saline from the Qinghai-Tibet plateau, over 3000m above sea level, which was formed through natural conditions.
The crystals, which are produced through a special manufacturing technique, are glittering and translucent.According to research carried out by the Environmental Research Center of the China Academy of Science, in addition to sodium chloride and iodine, there are also more than ten kinds of microelements in these products which are beneficial to the health of the human body. These are valuable characteristics for edible salts. These products were certified as environmentally friendly food by the Center of Chinese Environmentally-Friendly Development in 2001.
