Citric Acid (CA) is an important organic acid, also known as citric acid. Its molecular formula is C₆H₈O₇. It is a colorless crystal. It often contains a molecule of crystal water. It is odorless, has a strong acidity, and is easily soluble in water. . Its calcium salt is more soluble in cold water than hot water. This property is commonly used to identify and isolate citric acid. Anhydrous citric acid can be obtained by controlling the appropriate temperature during crystallization. It has many uses in industry, food industry, cosmetic industry, etc.

food industry
Citric acid is the world's largest organic acid produced by biochemical methods. Citric acid and salts are one of the pillar products of the fermentation industry, mainly used in the food industry, such as sour agents, solubilizers, buffers, antioxidants, Deodorizing deodorant, flavor enhancer, gelling agent, toner, etc.
In terms of food additives, it is mainly used for carbonated beverages, fruit juice beverages, lactic acid beverages and other refreshing beverages and pickled products, and its demand varies depending on the seasonal climate. Citric acid accounts for about 2/3 of the total consumption of sour agents. Adding citric acid to canned fruits can maintain or improve the flavor of the fruits in the collection, increase the acidity (lower pH value) of some fruits with lower acidity during storage (reduce the pH value), weaken the heat resistance of microorganisms and inhibit their growth, and prevent low acidity Bacterial swelling and destruction of canned fruits often occur. Adding citric acid as a sour agent to sweets is easy to coordinate with fruity taste. The use of citric acid in gel foods such as sauces and jellies can effectively reduce the negative charge of pectin, so that hydrogen bonds between pectin molecules can be combined to gel. When processing canned vegetables, some vegetables react in an alkaline manner. Using citric acid as a pH adjuster can not only play a seasoning role, but also maintain its quality. Citric acid has the characteristics of chelation and pH adjustment so that it can increase the performance of antioxidants in the processing of quick-frozen food, inhibit enzyme activity, and extend the shelf life of food.
Metal cleaning
Citric acid is an organic acid produced by microbial fermentation. It is widely used in detergent production. Its own specificity and chelation play a positive role. Citric acid has good performance in the actual use process, mainly in terms of safety. The raw materials for preparing citric acid are all derived from food, which is a safe food-grade microorganism. The use of citric acid has no impact on the environment, it is relatively easy to degrade under the action of microorganisms and heat, and its own chelating ability is also relatively strong, mainly citrate has strong chelation to manganese ions and iron ions, etc. Ability, use effect is also more prominent. The corrosion resistance of citric acid in detergents is also outstanding. Pickling is an important part of chemical cleaning. Compared with inorganic acids, the acidity of citric acid is relatively weak. The corrosiveness generated is relatively small, the safety and reliability of citric acid cleaning is relatively strong, and the waste liquid is relatively easy to handle, which will not cause harm to the human body.


SODIUM CITRATE


Sodium citrate is the most important citrate. It is mainly produced by fermentation of starch materials to produce citric acid, which is then neutralized with alkali materials. It has a variety of unique and excellent properties.

Construction industry
In the construction industry, sodium citrate can be added as a retarder when making concrete, which can improve the frost resistance, compression resistance and tensile performance of cement products; under the social conditions with increasing environmental problems, some smelting plants empty Sulfur dioxide in the flue gas is seriously exceeding the standard, and some studies have shown that using the characteristics of sodium citrate itself to remove sulfides in industrial exhaust gas has obvious effect.
