Product Description

Sodium Citrate, chemically named Trisodium 2-hydroxypropane-1,2,3-tricarboxylate, is a premium organic sodium salt derived from starch/sugar-based raw materials via microbial fermentation, citric acid purification and neutralization reaction. The commercial mainstream is dihydrate sodium citrate (Na₃C₆H₅O₇·2H₂O), appearing as colorless transparent orthorhombic crystals or white crystalline powder, odorless, with a mild salty-cool taste.
As the most widely used citrate salt in the global food industry, it features excellent pH buffering performance, powerful metal ion chelating ability, high water solubility and thermal stability. Manufactured following GB 1886.25-2016 and FCC/E331 international standards, it adopts fully grain-derived raw materials, zero toxic residues. JECFA (FAO/WHO) has no ADI limit for this product, confirming it as a zero-restriction safe food additive for global food processing.
Different from single-functional additives, sodium citrate integrates buffering, chelating, emulsifying, stabilizing and flavor-modifying properties, serving as a versatile core auxiliary ingredient for food, pharmaceutical and detergent industries.

Core Functional Advantages (Food Industry Focused)

Focus on industrial application value, eliminate non-food irrelevant medical misinformation, highlight B-end core performance:
  • Superior pH Buffering Stability Forms a stable buffer system with citric acid to lock product pH value, prevent acid degradation and flavor drift during high-temperature sterilization, long-term storage and cold chain transportation. Effectively maintains consistent taste and texture of finished products.
  • Powerful Metal Ion Chelation (Anti-Oxidation & Color Protection) Chelates calcium, iron and other metal ions in food raw materials, inhibits metal-induced oxidation, browning and fat rancidity. Prevents beverage precipitation, fruit product discoloration and dairy protein denaturation, greatly extending shelf life.
  • Multipurpose Functional Compatibility Integrates flavor correction, emulsification aid, gelling adjustment and anti-caking functions. Compatible with most food formulas, reduces the use of multiple single-function additives, simplifies production formulas and lowers overall costs.
  • High Thermal & Cold Chain Stability No decomposition or performance attenuation under high-temperature baking/sterilization and low-temperature freezing conditions, suitable for full-process thermal processing and cold chain food production.
  • Clean Label & Global Compliance E331 food additive code, compliant with EU, FDA and China food safety standards, no usage limit by law, fully fits clean label market trends.

Full-Scene Industrial Application Fields

1. Beverage Industry (Core Application)

Carbonated drinks, fruit juices, functional beverages, tea drinks, energy drinks. Used as pH buffer, flavor modifier and anti-precipitation agent; balances sourness of citric acid to avoid sharp sour taste, inhibits fruit juice browning and colloid precipitation, stabilizes beverage flavor and clarity.

2.Dairy & Fermented Products

Yogurt, milk drinks, processed cheese, condensed milk. Chelates calcium ions to prevent casein coagulation and protein precipitation; stabilizes dairy texture, avoids stratification during shelf life, and improves product smoothness.

3. Jam, Jelly & Fruit Processing

Fruit jam, jelly, fruit preserves, canned fruits. Adjusts gel strength of pectin to control jelly hardness and spreadability; prevents canned fruit discoloration and pulp shrinkage, optimizes taste and texture of gel products.

4. Baking & Confectionery

Cakes, biscuits, puff pastries, gummy candies, marshmallows. Acts as leavening aid and pH regulator for baking powder; adjusts candy gel texture, prevents sugar crystallization, and improves product crispness and mouthfeel.

5. Frozen & Instant Food

Frozen desserts, ice cream, quick-frozen pasta, instant soups. Improves freeze-thaw stability, inhibits ice crystal growth in ice cream, prevents texture deterioration of frozen food after repeated freezing and thawing.

6.Pharmaceutical & Daily Chemical Industry

Medical anticoagulant for clinical blood collection (chelates calcium ions to prevent blood coagulation); expectorant and diuretic raw material for pharmaceutical preparations; phosphate-free detergent auxiliary, electroplating buffer, brewing processing agent.
