Used in food industry


Citric acid has a mild and refreshing acidity, it is widely used in the manufacture of beverages, soda, wine, candy, snacks, biscuits, canned fruit juice, dairy products and other foods. Among all organic acids, citric acid has a market share of more than 70%. So far, there is no acid agent that can replace citric acid. One molecule crystalline water citric acid is mainly used as acidic flavoring agent for refreshing beverages, juices, jams, fructose and cans, and also as antioxidant for edible oils. At the same time, it can improve the sensory properties of food, enhance appetite and promote the digestion and absorption of calcium and phosphorus in the body. Anhydrous citric acid is widely used in solid drinks. Salts of citric acid, such as calcium citrate and iron citrate, are fortifiers that need to be added to certain foods. Esters of citric acid, such as triethyl citrate, can be used as non-toxic plasticizers to make plastic films for food packaging. They are sour agents and preservatives in the beverage and food industries.



For environmental protection


Citric acid-sodium citrate buffer is used for flue gas desulfurization. China is rich in coal resources, which is the main part of energy. However, there has been a lack of effective flue gas desulfurization technology, resulting in serious atmospheric SO2 pollution. At present, China’s SO2 emissions have reached nearly 40 million tons in the past two years. It is urgent to study an effective desulfurization process. Citric acid-sodium citrate buffer solution is a valuable desulfurization absorbent because of its low vapor pressure, non-toxicity, stable chemical properties and high SO2 absorption rate.
