Guangzhou ZIO Chemical Co., Ltd. is one of the leading manufacturers and suppliers of Citric Acid Monohydrate Powder in China. Welcome to buy bulk high quality chemicals in stock here from our factory. For price consultation, contact us.
Citric acid monohydrate (chemical formula C₆H₈O₇·H₂O) is a colorless crystal or white crystalline powder with an extremely sour taste. It is highly soluble in water and naturally exists in fruits such as lemons and citrus fruits. Industrially, it is mainly produced from starchy raw materials such as corn and tubers through the fermentation method of Aspergillus Niger. It is one of the most produced and widely used organic acids in the world. This product has a pure sour taste, strong pH adjustment ability and excellent metal ion complexation (chelation) properties. Therefore, it is widely used in multiple fields such as food and beverage, medicine and cosmetics, daily chemical cleaning, industrial manufacturing and livestock feed.
Citric acid monohydrate-characteristics and function
1. Food and Beverage Industry
(1)Acidulants and pH adjusters in beverages: used in carbonated drinks, fruit juices, sports drinks, and functional beverages to provide a refreshing, crisp acidity and adjust the pH to 2.5–4.0, enhancing flavor complexity and inhibiting microbial growth. Their excellent chemical stability makes them particularly suitable for beverages requiring long-term storage.
(2)Quality improvement of confectionery and baked goods: In hard candy production, it inhibits sucrose crystallization (prevents sugar bloom), resulting in a clear, smooth texture and improved mouthfeel; in cakes, breads, and other baked products, it helps maintain moist and soft texture by delaying starch retrogradation, thereby extending shelf life; when combined with baking soda, it acts as a leavening agent, promoting volume expansion and producing a crisp, flaky texture in cookies and pastries.
(3)Gel formation and color protection in jams, jellies, and dairy products: Adjusting pH promotes pectin gelation, helping jams and jellies achieve optimal firmness; in yogurt production, it regulates final acidity at fermentation endpoint to stabilize product quality. Additionally, its ability to chelate metal ions prevents enzymatic browning during processing and storage of fruit products, preserving bright color and enhancing freshness and color stability.
(4)Water-holding agents and quality improvers in meat products: Added to processed meats such as ham, sausages, and luncheon meats, they chelate calcium, magnesium, and other ions to relax protein structures, enhance water retention, thereby reducing cooking losses and improving slicing properties and texture.
(5)Applications in seasonings and edible oils: Enhances the natural sour and savory flavor in tomato sauce, soy sauce, and composite seasonings, resulting in a richer and fuller taste. It also acts as an antioxidant in edible oils by chelating trace metal ions that promote oil oxidation, thereby delaying rancidity and extending shelf life.
2. Pharmaceuticals and Cosmetics
(1)Pharmaceutical excipients and buffering agents: Widely used as pharmaceutical excipients in oral liquids, injectables, syrups, and other drug formulations, they help regulate product pH to improve taste or ensure drug stability. They can also be combined with salts such as sodium citrate to form buffer systems that maintain a constant acid-base balance of the solution during storage and use. Additionally, they are employed in preparing buffer solutions for clinical testing to measure blood potassium concentration.
pH adjusters and stabilizers in cosmetics: added to personal care products such as lotions, creams, serums, shampoos, and shower gels to regulate the acid-base balance (pH) of the formulation, ensuring the product is gentle and non-irritating to the skin, while maintaining the stability of other active ingredients in the formula.
(2)Exfoliating agents in functional skincare: As a type of alpha-hydroxy acid (AHA), they are added to functional skincare products for whitening, spot reduction, and anti-aging. By promoting the shedding of aged skin cells in the stratum corneum and accelerating the regeneration of new cells, they help improve rough skin texture, brighten complexion, and reduce fine lines.
3. Daily Chemicals, Detergents, and Industrial Applications
(1)Descaling and chelating agents in detergents: These are essential functional ingredients in synthetic detergent formulations (such as laundry powders, liquid detergents, and dishwashing liquids). Thanks to their acidic nature, they effectively dissolve calcium carbonate and other deposits found in scale. Additionally, by chelating hardness ions like calcium and magnesium in water, they prevent these ions from combining with surfactants, thereby maintaining cleaning efficiency. They also inhibit the redeposition of dirt and minerals onto fabrics or dish surfaces, significantly enhancing overall cleaning performance.
(2)Industrial equipment cleaning and descaling: widely used for chemical cleaning of industrial equipment such as boilers, heat exchangers, cooling tower pipelines, and reactors. It effectively dissolves accumulated inorganic deposits like calcium scale and rust inside the equipment, restores heat transfer efficiency, and extends equipment service life.
pH Adjustment and Biocidal Additives in Water Treatment: Used to regulate the pH of circulating cooling water, industrial recirculating water, and wastewater, maintaining the water system within an optimal acidic-alkaline range; the resulting acidic environment inhibits the growth and reproduction of certain bacteria and algae, providing auxiliary biocidal and algicidal effects.
(3)Process auxiliaries in electroplating and dyeing industries: used as pH adjusters in electroplating processes to maintain stable acidity or alkalinity of the plating solution, ensuring uniformity and adhesion of the coating; used as mordants in textile dyeing to help dye molecules firmly bind to fibers, improving color fastness and vibrancy.
(4)Building materials and other industrial applications: In the field of construction materials, it can be used as a concrete retarder to delay the hydration and setting time of cement, facilitating long-distance transportation and large-scale casting operations. In chemical analysis, it serves as an analytical reagent for detecting metal ions such as bismuth, aluminum, copper, mercury, and tin.
4. Livestock and Poultry Feed
In the livestock and poultry farming industry, citric acid is added as a feed acidifier to the diets of suckling pigs and growing-finishing pigs (typically at a concentration of 1%–2%). It helps lower gastrointestinal pH, suppresses the growth of harmful bacteria such as Escherichia coli, and promotes the proliferation of beneficial bacteria like lactic acid bacteria. This improves the digestion and utilization of nutrients such as protein, increases daily weight gain, reduces feed-to-gain ratio, and contributes to better carcass quality and meat flavor.
