Citric acid is very important in organic acids, which has 70% occupancy in the market. It has many uses in industry and food industry.
 
Citric acid can be used to make various reagents when used in industry, and can be used as a flavoring agent in the food industry. In addition, it can also be used as a disinfectant. It has a good sterilization effect.
 
The citric acid disinfectant includes polyhexamethylene guanidine, citric acid, lactic acid, and malic acid, and the balance is deionized water.
 
When citric acid is used for disinfection, it plays a role of corrosion inhibition and bacteriostasis.
 
Citric acid can quickly change the pH value in the environment and affect the normal metabolism of bacteria, thereby having an effect on disinfection.
 
Heat is also an important factor to promote the spore-killing effect of citric acid. Citric acid has no spore-killing effect at room temperature.
 
When the temperature is over 80°C, the permeability of the spore shell will be changed. The cell wall and membrane of the bacterial spore are also important points of heat. Meanwhile, the permeability of the solution will also increase.
 
Therefore, under the combined effect of heat and the citric acid aqueous solution, citric acid has an excellent sterilization and disinfection effects.
