E335 is a food additive known as citric acid. It is widely used in the food industry as a preservative, antioxidant, and acidity regulator.
Despite its name, citric acid is not directly related to lemons. It is produced through biochemical synthesis and can be of both natural and synthetic origin.
Excessive consumption of citric acid can negatively affect the state of ketosis due to its impact on blood pH.
Citric acid is most commonly used in beverages, canned goods, confectionery, juice drinks, syrups, marinades, cleaning agents, and many other products.
It is added to provide a sour taste, improve product consistency, and also acts as a stabilizer and antioxidant.
