Citric Acid Anhydrous, an organic compound with the molecular formula C6H10O8, is mainly used in the food and beverage industry as an acidifier, flavoring agent, preservative, and preservative.
It is widely use in many fields like the following:
Citric Acid Anhydrous is mainly used as an acidifier, flavoring agent, preservative, and preservative. It is used in the food industry. Because citric acid has a mild and refreshing sour taste, it is widely used in the manufacturing of various drinks, soda, wine, candy, Dim sum, biscuits, canned fruit juice, dairy products and other foods. It can give food a unique sour taste, improve its texture, and extend its shelf life.
Adding citric acid to piglet feed for livestock production can promote early weaning, increase feed utilization by 5% to 10%, and increase sow litter size. Adding 1%~2% citric acid to the diet of growing and fattening pigs can increase daily weight gain, reduce feed to meat ratio, improve protein digestibility, reduce back fat thickness, and improve meat quality and carcass characteristics.
In the field of medicine, Citric Acid Anhydrous has multiple uses. Firstly, it can be used as an in vitro anticoagulant to help prevent blood clotting. Secondly, Citric Acid Anhydrous can also be used to prepare cooling agents and other medications, which have the effects of relieving heat and clearing heat. In addition, due to its excellent buffering performance and chelating ability, Citric Acid Anhydrous is often used in pharmaceutical formulations to adjust pH, enhance drug stability, and bioavailability.
In the cosmetics industry, Citric Acid Anhydrous is mainly used as an antioxidant, pH regulator, and moisturizer. It can eliminate free radicals, prevent the oxidation and deterioration of oils and fragrances in cosmetics, thereby extending the shelf life of cosmetics. Meanwhile, Citric Acid Anhydrous can also adjust the pH value of cosmetics, making them more suitable for the pH level of human skin. In addition, due to its excellent moisturizing properties, Citric Acid Anhydrous can also help the skin maintain moisture, making the skin softer and smoother.
In the washing industry, Citric Acid Anhydrous can be used as a detergent additive. It can enhance the cleaning ability of detergents, remove stains and odors from clothing. Meanwhile, Citric Acid Anhydrous can also prevent alkaline components in detergents from damaging clothing, protecting the color and texture of the clothing. In the textile industry, it can serve as a dyeing aid to help dyes penetrate fibers more effectively; In the metal processing industry, it can be used as a cleaning agent to remove dirt and oxides from metal surfaces.

Feature of Citric Acid Anhydrous:
1. Good solubility, citric acid is easily soluble in water, ethanol, and ether. Citric acid has a high solubility in water, and in addition, citric acid and its derivatives in propylene glycol solution are also soluble in fats and oils. Due to its good water and fat solubility, citric acid is easily dispersed uniformly in various foods.
2. The sour taste is pure, mild and fragrant, and it is the most delicious among all organic acids. It can be mixed with various spices to produce a refreshing sour taste, and is used in many foods. Meanwhile, due to the weak acidity of citric acid, it can inhibit bacterial growth within a certain pH range and serve as a preservative.
3. Strong chelating ability, citric acid can form three forms of salts due to its three carboxyl groups, but most salts except alkali metal salts are insoluble or difficult to dissolve in water. It also has a peculiar property, which is that it is more soluble in cold water than in hot water.
4. It can form buffering agents with bases or salts, such as mixing with disodium hydrogen phosphate in different proportions, to obtain various buffering solutions.
5. Low toxicity, citric acid is an important intermediate in the tricarboxylic acid cycle in the human body and does not cause harm to the human body.
