Citric Acid Monohydrate An Essential Compound with Citric acid monohydrate, with its Chemical Abstracts Service (CAS) registry number 77-92-9, is a ubiquitous and highly versatile compound found in various aspects of our daily lives. It is a hydrated form of citric acid, a weak organic acid that plays a significant role in numerous chemical and biological processes. Citric acid monohydrate is derived primarily from natural sources, particularly citrus fruits like lemons and oranges, where it serves as a key component in the fruit's characteristic tartness. However, due to its extensive industrial use, commercial production often involves fermentation processes using Aspergillus niger, a common fungus. The molecular formula of citric acid monohydrate is C6H8O7.H2O, indicating one molecule of water bound to the citric acid. This hydration gives it distinct properties compared to anhydrous citric acid, making it more suitable for certain applications. The monohydrate form has a higher solubility in water, which is a critical factor in many industries. In the food and beverage industry, citric acid monohydrate is used as a flavoring agent, preservative, and pH regulator. It enhances taste, extends shelf life, and maintains product stability. Its acidic nature also helps prevent the growth of harmful microorganisms. In soft drinks, it provides the tangy taste, while in confectionery, it prevents sugar crystallization. In pharmaceuticals, citric acid monohydrate is employed as an excipient, assisting in drug formulation and delivery.
