Ang Siduo mineral water is produced in the town of Ang Siduo, Mayin Mountain at 3,860 meters above sea level on the Qinghai-Tibet Plateau. It has a history of 200,000 years of prehistoric rock formation, and it has been enriched by nature for 25 years. From the depths of the geological layer, the surface is spontaneously emerged; it is a rare natural spring. "Angsuo" Tibetan means "water source" and "upstream of the river valley".

"Angsi more" natural mineral water stability, the formation constant filtration process, no surface water infiltration and doping, PH value perennial stability between 7.52 ~ 7.78. Among them, strontium and metasilicate meet international standards at the same time. The ratio of calcium to magnesium is balanced and the water quality is balanced. It is a rare high-quality natural mineral water. The water source is in the Ansuodu Nature Reserve on the Qinghai-Tibet Plateau at an altitude of more than 3,000 meters. The mountain snow water infiltrates. After several years of natural filtration mineralization, the water contains various trace elements and minerals, which are more easily absorbed. Groundwater sources are directly filled to avoid exposure to air and pollution. National patent high-strength and high-permeability packaging design, no liquid nitrogen added. Adopt international advanced non-ozone double sterilization process, no bromate. After 30 consecutive random sampling tests in 5 years, 30 mineral indexes of Ansuodu Natural Mineral Water passed the inspection and verification at one time; among them, the two characteristic indexes of strontium and metasilicate were obviously superior to the national drinking mineral water standard. Ansuodu natural mineral water is very close to the structure of water molecules in human cells. It is a small molecular group structure with high biological affinity and permeability, easy to absorb, can quickly alleviate physiological needs, and timely and effectively adjust the immune system. Long-term consumption of rich mineral water can lower the body's cholesterol content, soften blood vessels, prevent high blood pressure and cardiovascular diseases, benefit bone growth and development, prolong life, health and strengthen the body, and can improve skin care, beauty and beauty. Ang Siduo mineral water is named after Ang Siduo Town, Hualong County, Qinghai Province. “Ang Siduo” is a Tibetan language, meaning “upstream of the river valley, water source”. The Angstrom area was originally a Tibetan grazing place. In the Ming Dynasty, the Long Bu tribe, one of the twenty-five ethnic groups of the Mafan tribe in Xining, had a small amount of farming. At that time, the water plants were rich and the forests were dense. Before the first year of Emperor Qianlong (1736), the Tibetan Ang Sidu tribe lived. After Qianlong four years (1739), the Hui and Han people moved in, and opened up wasteland to build villages. Some Tibetans moved to pastoral areas such as Hainan, and the population of Hui, Han and Salar grew rapidly, and gradually formed a region dominated by agriculture and concurrently engaged in animal husbandry. In the first year of Qing Xuantong (1909), there were Ang Duo Zhuang, Huang Ka Wazhuang and Mei Jia Zhuang. The Ansuodu mineral water source is located in Angdo Town, a small town in the northern part of the county of Hualong Hui Autonomous County in Qinghai Province. It is 25 kilometers away from the resident of Hualong Hui Autonomous County and covers an area of ​​83.9 square kilometers. At 3,860 meters above sea level, Ma Yinshan under the Ang Siduo Nature Reserve, the area is high in air, clean in air, pleasant in scenery, rich in water resources and excellent in water quality. Angstrom mineral water is rich in macro elements and a variety of trace elements and components that are beneficial to human health, which are closely related to the formation lithology, geological structure and groundwater formation conditions in the area. The reserves of mineral water in Ansuoduo are large, and the characteristics of mineral waters of both strontium and metasilicate are better than national standards. In addition to rich in nutrients such as barium and metasilicate, it also contains more than 20 essential trace elements such as potassium, sodium, calcium, magnesium, lithium, zinc, bromine and iodine. According to the investigation and evaluation of the experts of China Mineral Water Special Committee on the spot and the dynamic analysis of mineral water, the spring water comes from deep circulating water, and the flow rate is relatively stable. The maximum flow of several springs is 2000 cubic meters per day, and the minimum flow is 1700 cubic meters. / Day, the annual output of the minimum flow meter can reach 600,000 tons. On the morning of March 15, 2015, sponsored by China Ministry of Environmental Protection, China Environmental Protection Association, China Consumer Protection Rights Association, International Healthy Drinking Water Industry Alliance, Beijing Public Health Drinking Water Research Institute, China Health Promotion Foundation, China Environmental Protection The “2015 China Excellent Water Map and Drinking Water Index N1 Conference” hosted by the Foundation was held at the Beijing International Convention Center. Angstrom Mineral Water was invited to attend the event. In the N1 China Excellent Water Map announced this time, the natural water source of the Anshunduo Plateau on the Qinghai-Tibet Plateau was included in the map of China's excellent water. The Ansuodu water source is located in the town of Ang Siduo, Mayin Mountain, Qinghai-Tibet Plateau. It is rich in water resources and has excellent water quality. It is known as the “plateau water town”. The Tibetan word "Angsuo" means "water source, river valley upstream". During the Cretaceous orogeny movement of the Qinghai-Tibet Plateau, Lajishan and Ma Yinshan collided to form a stratum reclamation. After the glacier snow water passed through the deep crust of the crust, the surface of the strata broke up and overflowed to form a rare low salinity-containing silicon. Acid, strontium mineral water, the water is sweet and delicious, clear and transparent. In addition, it contains more than 30 kinds of trace elements and minerals necessary for human body such as potassium, sodium, calcium, magnesium, lithium and zinc. The natural spring water of Yongsuo Plateau Yongquan is highly recognized and respected by the participating experts and guests.

Technical requirements for the quality of Ansuodu mineral water 1. The water source is produced within the scope of the spring. Second, water source protection must establish a three-level protection zone. 1. 2. 3. Tertiary protection zone: According to the replenishment status of the water source, a monitoring zone of not less than 1km is set up. Third, the amount of mining per day does not exceed 2000t. Fourth, the production process 1. Process: raw water mining → water treatment → sterilization → filling → packaging → finished products. 2. V. Quality characteristics 1. Sensory features: pure water, sweet water, soft entrance, better taste at low temperature. 2. Safety and other quality technical requirements: Product safety and other quality technical requirements must comply with relevant national regulations.
