Anhydrous citric acid (chemical formula C₆H₈O₇, CAS 77-92-9) is the non-hydrated form of citric acid, appearing as colorless crystals or a white crystalline powder. It is odorless, extremely sour in taste, and highly soluble in water. Naturally occurring in citrus fruits such as lemons and oranges, it is industrially produced mainly from starchy raw materials like corn and tubers through fermentation using Aspergillus niger. It is one of the most widely used organic acids in food, pharmaceuticals, and chemical industries. Compared to monohydrate citric acid (containing one molecule of water), there is no substantial difference in application; however, anhydrous citric acid should be preferred in situations where moisture sensitivity is a concern. Recognized as a safe food additive (GB 1886.235-2016, E330), it offers pure acidity, pH adjustment, and metal ion chelation capabilities, making it widely used in food and beverages, pharmaceuticals, personal care and cleaning products, and industrial manufacturing.
The Application-Citric acid anhydrous
1. Food and Beverage Industry
Acidifiers and pH regulators in beverages: Widely used in carbonated drinks, fruit juices, sports drinks, and functional beverages, they provide a refreshing and invigorating sour taste and adjust the pH value to 2.5-4.0 to enhance the flavor profile and inhibit microbial growth. The powder form of anhydrous citric acid enables more uniform mixing and faster dissolution in instant beverage powder.
Quality improvement of candies and baked goods: In the production of hard candies, inhibiting the crystallization of sucrose (preventing re-crystallization) to make the candy texture transparent; in cakes and breads, helping to maintain a moist texture and delaying the aging of starch; when combined with baking soda, it can be used as a leavening agent to make biscuits and pastries crispy and flaky.
Jelly, jam and dairy products' gelation and color preservation: By adjusting the pH value, it promotes the formation of gelatin, helping jam and jelly achieve the desired gelation state; complexing metal ions can prevent the browning of fruit products and maintain bright color.
Water retention and color protection agents in meat products: Added to meat products such as ham and sausage, they combine with calcium ions to relax the structure of muscle proteins and enhance water retention ability, reducing cooking loss by 5% to 10%, while preventing the products from oxidizing and discoloring.
Applications in seasonings and cooking oils: Enhance the fresh sourness in tomato sauce and salad dressing; Act as an antioxidant in cooking oils, by complexing trace metal ions to delay the deterioration of oil oxidation.
2. Medicine and Nutritional Health Care
Pharmaceutical excipients and buffers: Widely used in oral liquids, injections, syrups and other pharmaceutical preparations to adjust the pH value of the products or combine with citrate salts to form a buffering system, maintaining the stability of the liquid medicine.
Dispersible preparations and oral rehydration salts: They are the key components of dispersible tablets and dispersible granules. When exposed to water, they produce carbon dioxide bubbles, enhancing the taking experience; they are also used to prepare oral rehydration salt powders.
Dietary supplement raw materials: Used for the production of potassium citrate and other mineral supplements, to help replenish essential elements in the human body.
3. Cosmetics and Personal Care Products
pH adjustment and formulation stabilizer: Added to products such as lotions, creams, shampoos, and body washes, it regulates the acid-base balance, ensuring the product's mildness and maintaining the stability of the formulation.
Skin care active ingredients: As a type of alpha-hydroxy acid (alpha-hydroxy acid), it is added to whitening and anti-aging products to promote the metabolism of the stratum corneum and improve skin quality.
Bubble bath products: Used in bath balls (foaming bath salts) and other products, they undergo a carbonation reaction when exposed to water, providing a soothing bathing experience.
4.Personal Care Cleaning and Industrial Applications
The scale removal and chelating additives in detergents: They are important functional components in products such as laundry powder and dishwashing agents. They can dissolve calcium carbonate in scale, and simultaneously chelate hardness ions such as calcium and magnesium, enhancing the cleaning effect and preventing the re-deposition of dirt.
Household and industrial scale removal and cleaning: Used for chemical cleaning and scale removal of equipment such as water kettles, water dispensers, boilers, heat exchanger pipes, etc., quickly dissolving inorganic deposits.
Other industrial applications: Used as a pH adjuster in electroplating processes; As a mordant agent in the printing and dyeing industry to help fix colors; Used as a retardant in concrete construction; Used as an analytical reagent and buffer solution in chemical analysis.
