What is anhydrous citric Acid?
Anhydrous citric acid has the chemical name of citric acid and its appearance is a white, odorless and colorless powder. Anhydrous means that the substance is waterless and anhydrous and granulated. Citric acid is found naturally in plants and animals.
Citric acid is a natural fruit acid that is commercially produced through the microbial fermentation of a layer of carbohydrates. Citric acid is the most widely used organic acid and pH control agent in foods, beverages, drugs and technical applications. It is toxic to plants and should not be used in valuable plant life. Citric acid as a weak organic acid is mainly used in the food and beverage industries as a sour, flavoring and preservative. It is also used as an antioxidant, emollient and detergent in the chemical, cosmetic and laundry industries.
Anhydrous citric acid is non-toxic. It is chemically stable if stored at room temperature. Stability tests have shown that anhydrous citric acid is chemically stable for at least five years in tightly closed containers under proper storage conditions. The main basis of citric acid, citrate, is a component of the Krebs cycle and occurs naturally during metabolism in all living organisms. It is found naturally in citrus fruits such as lemons and lemons and is used as a natural preservative.
Citrate or citric acid is often used to regulate pH, add a sour taste to foods and beverages, and to form mineral and metal salt derivatives for medicines. Like potassium citrate, it is a dietary supplement. Citrate salts, including citric acid, are commonly known to be safe when used in natural amounts, according to the FDA Selection Committee on Food Safety (GRAS).
What does the word anhydrous in anhydrous citric acid mean?
That is, free of water and especially crystallized water.
Physical and chemical properties
Anhydrous citric acid was first isolated from lemon juice in 1784 by Swedish chemist Carl Wilhelm Scheele.
A colorless, crystalline organic compound belonging to the carboxylic acid family is present in almost all plants and in many animal tissues and fluids. It is one of the compounds involved in the physiological oxidation of fats, proteins and carbohydrates to carbon dioxide and water.
Citric acid is produced by fermenting sugarcane or sugar syrup in the presence of Aspergillus niger. It is used in sweets and non-alcoholic beverages (as a flavoring agent), in metal-cleaning compounds, and in improving the stability of food and other organic matter (by suppressing the harmful function of soluble metal salts).
Anhydrous citric acid appears as colorless crystals or as a white crystalline powder with a completely acidic taste. It is highly soluble in water, soluble in free ethanol (96%) and slightly soluble in ether.
Citric acid has little reactivity. If stored at room temperature, it is chemically stable. Anhydrous citric acid is completely biodegradable (substances that are naturally degradable in the environment, especially by microorganisms, are called biodegradable materials)
Citric acid is a natural fruit acid that is commercially produced by microbial fermentation of a carbohydrate substrate. Citric acid is the most widely used organic acid and pH controller in foods, beverages, drugs and technical applications.

Is anhydrous citric acid safe?
In Europe, anhydrous citric acid is generally listed as a food additive (E330) and can be added to all foods. According to the principle of “quantum satis”, it can be used as long as no specific law restricts or prohibits its use.
The US Food and Drug Administration (FDA) has approved citric acid as GRAS (generally known as safe) and approved its use in food in accordance with current GMP (CFR § 184.1033).
