What is Citric Acid?
Citric acid is an organic compound naturally found in various fruits, particularly in citrus fruits like lemon or orange. One of its most relevant characteristics is that it functions perfectly as a preservative due to being a natural antioxidant.
How is it Obtained?
Commercially, it is available as a white, crystalline powder that is odourless and has a very sour taste. It can be extracted from different parts of plants, such as lemon juice, but nowadays, it is obtained through a fermentation process.
This process involves various substrates and microorganisms, with the most common being the fungus *Aspergillus niger*. Once the fermentation process is complete, citric acid is separated from the rest and subjected to a purification and crystallization process, resulting in the white powder used in various applications.
