citric acid in food industry
Citric acid is the largest organic acid produced by biochemical methods in the world. 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, Deodorant, flavor enhancer, gelling agent, toner, etc. 
In terms of food additives, it is mainly used in carbonated beverages, fruit juice beverages, lactic acid beverages and other refreshing beverages and pickled products. The demand is subject to seasonal climate changes. 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 fruit, increase the acidity of some fruits with lower acidity (decrease the pH value), weaken the heat resistance of microorganisms and inhibit their growth, and prevent those with lower acidity. Bacterial swelling and destruction often occurs in canned fruits. Adding citric acid as a sour agent in candies is easy to harmonize with fruit flavor. The use of citric acid in gel food such as sauce and jelly can effectively reduce the negative charge of pectin, so that the intermolecular hydrogen bonds of pectin will be combined and gelled. When processing canned vegetables, some vegetables show alkaline reaction. Using citric acid as a pH regulator can not only play a role in flavoring, but also maintain its quality. Citric acid has chelation and pH adjustment properties, which 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 specificity and chelation effect play a positive role. In the actual use process, citric acid has a good performance, mainly in terms of safety. The raw materials for preparing citric acid are all derived from grain, which is a safe food-grade microorganism. The use of citric acid will not affect the environment. It is relatively easy to degrade under the action of microorganisms and heat. Its own chelating ability is also relatively strong. It is mainly timely that citrate has relatively strong chelation to manganese ions and iron ions. Ability and use effect are also more prominent. The performance of citric acid in detergents is also more prominent in corrosion inhibition. Pickling is an important part of chemical cleaning. Compared with inorganic acids, the acidity of citric acid is relatively weak. The corrosiveness produced is also relatively small, the safety and reliability of citric acid cleaning is relatively strong, and the waste liquid is relatively easy to handle, and it will not cause harm to the human body. 
(1) Citric acid cleaning mechanism
Citric acid has little corrosion to metals and is a safe cleaning agent. Because citric acid does not contain Cl-, it will not cause stress corrosion of equipment. It can complex Fe3+ and weaken the promotion of Fe3+ corrosion. 
Citric acid can dissolve iron oxide and copper oxide to form a complex of ferric citrate and copper. If ammoniated citric acid solution is used, it can form a highly soluble complex of ferrous ammonium citrate and ferric citrate, with a cleaning effect Very good, citric acid is mainly used to remove rust, so it is mainly used to clean new boilers. Citric acid is mixed with sulfamic acid, glycolic acid or formic acid to clean the calcium magnesium scale and rust in the boiler, citric acid and ethylene dichloride Amine tetraacetic acid (EDTA) can be used to clean the superheater. 
Citric acid and its derivatives are widely used in many fields such as chemical cleaning due to their special physical and chemical properties. 
(2) Citric acid cleaning pipeline
This is the latest cleaning technology for high-impurity hard water. It uses food-grade citric acid to soften stubborn scales, and then uses microcomputers to control water flow and pneumatics to produce water shocks, which can peel off the old scales in the water pipes, and make the water pipes unblocked and high frequency. Citric acid cleaning technology, the fastest, safest and effective construction method, does not use ozone or chemical reagents and has low cost. 
(3) Compound surfactants to clean gas water heaters
The chemical cleaning agent formulated with citric acid, AES and benzotriazole cleans the gas water heater that has been used for many years. Pour the cleaning agent into the inverted water heater, soak for 1 hour, pour out the cleaning liquid, rinse with clean water, and reuse the water heater. Under the same flow rate, the temperature of the outlet water increases by 5℃~8℃. 
(4) Cleaning the drinking fountain
Dilute with edible citric acid (powdered) with water, pour it into the heated inner tank of the water dispenser, and soak for about 20 minutes. Finally, rinse the inner tank repeatedly with clean water until it is clean, non-toxic and effective. 
Fine chemical industry
Citric acid is a kind of fruit acid. Its main function is to accelerate the renewal of keratin. It is often used in lotions, creams, shampoos, whitening products, anti-aging products, and acne products. In chemical technology, citric acid can be used as a reagent for chemical analysis, as an experimental reagent, as a chromatographic analysis reagent and as a biochemical reagent; as a complexing agent, a masking agent, and as a buffer solution. Using citric acid or citrates as builders can improve the performance of washing products, quickly precipitate metal ions, prevent pollutants from re-attaching to the fabric, and maintain the necessary alkalinity for washing; disperse and suspend dirt and ash; It is an excellent chelating agent to improve the performance of surfactants; it can be used as a reagent for testing the acid resistance of architectural ceramic tiles. Citric acid-sodium citrate buffer is used for flue gas desulfurization. my country is rich in coal resources and constitutes the main part of energy. However, there has been a lack of effective flue gas desulfurization technology, which has caused serious atmospheric SO2 pollution. Citric acid-sodium citrate buffer solution is a desulfurization absorbent with great development value due to its low vapor pressure, non-toxicity, stable chemical properties, and high absorption rate of SO2. 


In the traditional dyeing and finishing process, finishing is usually performed after dyeing. Due to the cross-linking treatment in finishing, the problem of color fastness and color difference is often caused, especially when the reduction catalyst is selected, this phenomenon is more obvious. One-step processing of fabrics can not only reduce costs and shorten production time, but also avoid problems of color fastness and color difference. At present, the simultaneous dyeing and finishing is mainly used for cotton, cotton blended fabric, silk, wool and viscose fiber. The common feature of these fibers is the need to improve their wearability through finishing; the one-step and two-step dyeing and finishing methods have obtained better finishing effects, but the one-step method can save energy, the process is simple, and the pollution is small, so it has good Development prospects. 


Citric acid can be used as a formaldehyde-free dyeing finishing agent. Triethanolamine can prevent citric acid from decomposing and dehydrating to form unsaturated polycarboxylic acid during the fabric baking process, thereby effectively inhibiting the yellowing of the fabric. [12]
Citrate esters have been approved by the US Food and Drug Administration as non-toxic plasticizers for polyvinyl chloride and cellulose plastic films used in food packaging. Acetylated and butylated citrate esters can be used as foaming agents for methyl methacrylate polymers, stabilizers for acrylamide, initiators for polyamide binders, and plasticizers for polyvinyl chloride. In particular, butyl citrate and acetylated tributyl citrate are universally recognized non-toxic plasticizers. In addition to being non-toxic, it has superior performance in compatibility, extraction resistance, and low volatility. For example, acetylated trihexyl citrate and butylated tributyl citrate can be used to produce blood vessels and catheters with high hygiene requirements. 


Sterilization and coagulation process
The combined effect of citric acid and 80°C temperature has a good effect of killing bacterial spores, and can effectively kill bacterial spores contaminated in the hemodialysis machine pipeline. During the formation of prothrombin activator and the subsequent clotting process, calcium ions must be involved. Citrate ions and calcium ions can form a soluble complex that is difficult to dissociate, thereby reducing the concentration of calcium ions in the blood and hindering blood coagulation.
