Food Grade Anhydrous Citric Acid as Acidity Regulator for Beverage Production

Anhydrous Citric Acid (CAS:77-92-9, molecular formula C₆H₈O₇) is a high-purity organic acid produced via deep fermentation of corn starch and glucose raw materials followed by multi-step crystallization, dehydration and refined purification. It appears as colorless or white transparent granular crystal or crystalline powder, odorless with pleasant mild sour taste, featuring superior water solubility and excellent dissolving performance in cold and hot water, also slightly soluble in ethanol. Different from monohydrate citric acid, anhydrous type owns low free water content and stable crystal structure, not prone to caking under normal storage environment. Thanks to its outstanding acidity adjustment, metal ion chelation, antioxidant synergism and buffering capability, it has become the most widely used safe edible acidulant globally, complying with FCC, BP, USP and international food additive standards. Our production adopts closed automatic fermentation and continuous drying technology to strictly control residual sugar, heavy metal and microbial indicators, stable effective content, widely applied across food & beverage, pharmaceutical manufacturing, daily detergent, industrial water treatment and fine chemical synthesis fields.

Applications
**Food and Beverage Industry (Core Consumption Field)**: It is the dominant acidity regulator for carbonated drinks, fruit juices, functional energy drinks, fruit vinegar and concentrated syrups, improving fruit flavor, adjusting product sour-sweet balance and inhibiting microbial breeding to prolong shelf life. In confectionery, hard candy, jelly and jam processing, anhydrous citric acid enhances sour taste, stabilizes fruit pigment and prevents finished products from fading and deterioration. It is also commonly added into baked goods, canned fruits and frozen food to restrain enzymatic browning, retain raw material fresh color and original flavor. For dairy products such as yogurt and cheese, it serves as mild coagulant and pH stabilizer to optimize finished product texture.

**Pharmaceutical & Health Care Product Industry**: Widely applied as raw material for effervescent tablets, vitamin preparations and oral granular medicines. It reacts with sodium bicarbonate to produce carbon dioxide for effervescent formulation molding; meanwhile used as blood anticoagulant auxiliary and acidifier for medicinal syrups, adjusting medicine taste to cover bitter odor of active pharmaceutical ingredients. In external ointment formulation, it works as pH modifier to stabilize ointment system and promote percutaneous absorption of medicinal components.
**Daily Chemical & Detergent Manufacturing**:Important functional additive for facial cleanser, shampoo, body wash and high-grade solid cosmetics. Its powerful chelation performance binds calcium and magnesium ions in hard water to improve surfactant cleaning efficiency, stabilize cosmetic emulsification system and avoid formula stratification. In household descaling cleaners and industrial neutral detergents, anhydrous citric acid replaces strong inorganic acid to safely remove water scale, mineral sediment on home appliances and pipeline without severe corrosion on metal and plastic components.
**Industrial Water Treatment & Electroplating Industry**:High-efficiency environment-friendly chelating agent for industrial circulating cooling water and boiler water treatment, complexing calcium, magnesium and heavy metal ions to restrain pipeline inner wall scaling and reduce equipment maintenance frequency. In electroplating industry, it acts as pH buffering agent and complexing additive for nickel plating, zinc plating solution, optimizing plating layer uniformity and glossiness while reducing harmful wastewater discharge.
**Fine Chemical and Other Fields**:Key raw material for synthesizing citrate series products including sodium citrate, potassium citrate, which are further used in food additives and chemical auxiliaries; also used as catalyst and pH regulator in organic esterification and chemical intermediate synthesis.

Product Advantages
✅ Low free moisture characteristic of anhydrous crystal effectively avoids raw material caking during long-term storage and transportation, far more suitable for high-temperature formula production compared with monohydrate citric acid.
✅ Strict microbial and heavy metal control system conforms to global mainstream food grade specifications, available for food, medicine and export food additive certification requirements.
✅ Two particle specifications (fine powder and uniform crystal granule) optional: fine powder dissolves instantly for liquid formulation, large crystal reduces dust generation for automatic feeding production line.
✅ Full batch inspection before shipment, complete COA test report, MSDS and relevant food qualification documents provided for customs clearance of various countries.
✅ Large-scale continuous production line guarantees abundant spot stock, supporting small sample trial purchase and full-container long-term framework order with fast delivery arrangement.
