Citric acid, a compound present in animal tissues and various fruits, serves a multitude of purposes. In the food and beverage industry, commercially manufactured citric acid is widely used as a marinade for meats, a safeguard against botulism, and a flavor enhancer in soft drinks and candies. Its antioxidant properties also make it a valuable ingredient in many cosmetic products.
While citric acid is not classified as an essential nutrient, supplementation can provide protection against certain conditions. Nevertheless, it’s important to note that excessive consumption of this compound can lead to serious health complications, especially when combined with certain medications.
Citric Acid’s Role in the Krebs Cycle
The Krebs cycle, also known as the citric acid cycle, plays a crucial role in various physiological processes. Citric acid, a vital compound within this cycle, is involved in the final stages of oxidizing amino acids, carbohydrates, and fatty acids. This series of chemical reactions is responsible for generating nearly two-thirds of the energy utilized by cells in humans and numerous other organisms.
Manufacturing Process of Citric Acid
Citric acid is a common ingredient found in various products, but many people are unaware of its true origin. Contrary to popular belief, the citric acid used in these products is not derived from citrus fruits. Extracting citric acid from fruit is not only expensive but also unable to meet the high demand. Instead, approximately 99% of the citric acid available in the market is produced through the fermentation of sugar and a mold called Aspergillus niger.
Although this manufacturing process has proven to be efficient, it has raised concerns among some individuals. Aspergillus niger is known to be an allergen, and there are worries about potential residue remaining in the final citric acid product. Despite efforts to remove the mold during manufacturing, some researchers suggest that traces of it may still be present. This has led to the belief that consuming manufactured citric acid could potentially trigger inflammatory reactions in certain individuals.
