Chemical Formula :
General description :
Citric acid is available in a synthetic form that is extensively used as a food ingredient, cleaning agent, and nutritional supplement. This synthetic version, however, is not the same as what is found naturally in citrus fruits.
Citric acid is one of the most usual food preservatives and flavoring additions. Citric acid is found naturally in citrus fruits, particularly lemons and limes, but it can also be synthesized. Its what gives them their tangy and sour flavour. Fermentation is used to make it commercially. It comes in the shape of a white crystalline powder. In foods, drinks, pharmaceuticals, and technical applications, it is the most frequently used organic acid and pH-control agent.
A Swedish researcher isolated citric acid from lemon juice. Citric acid is mostly employed as a flavouring and preserving ingredient, especially in soft drinks and candies, due to its acidic, sour taste.
Application & Usage:
- Citric acid has a wide range of applications in the food industry. It serves as a flavour enhancer, a preservative, and aids in the ripening process by considerably slowing the oxidation process. It is used to alter the pH of solutions in both beer and wine brewing. It also prevents the crystallisation of sugar in caramels.
- Citric acid works as a chelating agent, making metals soluble and so binding them. It is used to clean and prevent limescale buildup in boilers and evaporators. It may be used to purify water, making it beneficial for enhancing the efficacy of soaps and laundry detergents. A solution of citric acid with a concentration of 6% will remove hard water stains from the glass without scrubbing.
- Citric acid is used to remove rust from steel and passivate stainless steel in industries.
- Citric acid is a type of alpha-hydroxy acid that is used in chemical skin peels.
- Citric acid is employed as one of the active ingredients in the manufacture of antiviral facial tissues.
- Citric acids pH-controlling characteristics are employed in household cleaners and pharmaceuticals.
- Citric acid, either dry or as a concentrated solution in water, is a good soldering flux.
- Citric acid is used in edible oil as a degumming agent.
- Citric acid is a disinfectant and cleaning agent that can be used to remove soap scum, hard water stains, lime, and rust.
