As a professional international trading company based in Shanghai, Murong (Shanghai) International has established itself as a trusted supplier of food-grade chemicals with particular expertise in citric acid production and distribution. With over a decade of experience in water treatment materials and food additives trading, our company now serves global clients in the food processing, beverage, pharmaceutical, and cosmetics industries through our comprehensive range of food-grade citric acid products.
Our commitment to quality begins with strict supplier selection and continues through our advanced quality control systems. We work exclusively with ISO-certified factories that implement GMP (Good Manufacturing Practice) standards throughout the production process. This ensures our food-grade citric acid consistently meets international quality requirements including FCC, BP, USP, and E330 standards.
Product Range and Specifications
As a specialized food grade citric acid supplier, we offer both monohydrate and anhydrous forms to meet different industrial requirements:
- Citric Acid Monohydrate (C6H8O7·H2O): Contains one molecule of water per citric acid molecule (approximately 8.4% water content). Widely used in food preservation, beverage acidulation, and pharmaceutical applications where controlled moisture content is beneficial.
- Citric Acid Anhydrous (C6H8O7): Completely water-free form with higher acidity per gram. Preferred for applications requiring maximum acid strength with minimal volume, including dry mix formulations, cleaning products, and certain pharmaceutical applications.
Both forms are available in various packaging options from 25kg bags to 1,000kg bulk bags, with custom packaging solutions available for specialized requirements. Our flexible supply chain allows us to accommodate both small trial orders and large-scale industrial purchases with consistent quality assurance.
Quality Control and Certification
Understanding the critical importance of quality in food-grade chemicals, we implement a multi-stage quality control process:
1. Raw Material Inspection: All incoming citric acid must pass initial purity tests before entering production
2. Production Monitoring: Continuous in-process quality checks during crystallization, drying, and packaging
3. Final Product Testing: Comprehensive analysis including heavy metal detection, microbial testing, and pH verification
4. Batch Documentation: Complete traceability records maintained for every production batch
Our food-grade citric acid products come with complete certification packages including:
- ISO 9001:2015 Quality Management System
- ISO 22000:2018 Food Safety Management
- FCC (Food Chemicals Codex) compliance
- Kosher and Halal certifications available upon request
- Detailed CoA (Certificate of Analysis) with each shipment

| Molecular Weight | 210.14 g/mol | 192.13 g/mol |
| Water Content | 7.5-9.0% | ≤0.5% |
| Assay (as C6H8O7) | ≥99.0% | ≥99.5% |
| Solubility (20°C) | 64 g/100ml | 133 g/100ml |
| pH (1% solution) | 2.0-2.5 | 2.0-2.5 |
Applications in Food Industry
As a versatile food additive, our citric acid products serve multiple functions across various food processing applications:
1. Acidulant and pH Regulator: Used to control acidity in beverages, jams, jellies, and canned foods. Helps maintain product stability and prevent microbial growth while enhancing flavor profiles.
2. Preservative: Inhibits enzymatic browning in fruits and vegetables, extends shelf life of processed foods by chelating metal ions that catalyze oxidation reactions.
3. Flavor Enhancer: Provides tart, refreshing taste in soft drinks, confectionery, and dairy products. Often used in combination with other sweeteners to balance flavors.
4. Emulsifying Agent: Stabilizes oil-in-water emulsions in processed foods like mayonnaise and salad dressings. Improves texture and prevents separation during storage.
5. Buffering Agent: Maintains desired pH levels in food processing systems, particularly important in cheese making, wine production, and fermentation processes.
Our technical team works closely with clients to determine the optimal citric acid form and dosage for specific applications, considering factors such as processing conditions, final product requirements, and regulatory constraints.
FAQ
What certifications do your food grade citric acid products have?
All our food grade citric acid products come with ISO 9001, ISO 22000 certifications, and comply with FCC (Food Chemicals Codex) standards. We can also provide Kosher and Halal certificates upon request to meet specific market requirements.
How do you ensure consistent quality in large-scale production?
We implement a comprehensive quality management system that includes raw material inspection, in-process quality checks, and final product testing. Each production batch is accompanied by a detailed Certificate of Analysis showing all test results and specifications compliance.
What’s the difference between monohydrate and anhydrous citric acid for food applications?
The main difference is water content – monohydrate contains about 8.5% water while anhydrous is completely water-free. Anhydrous citric acid has higher acid strength per gram and better solubility, making it preferred for dry mix formulations. Monohydrate is often used where controlled moisture content is beneficial.
Can you provide customized packaging solutions for food grade citric acid?
Yes, we offer flexible packaging options ranging from 25kg PE bags to 1,000kg bulk bags. For special requirements, we can provide customized packaging solutions including smaller consumer packs or specific labeling for private brand applications.
What is your minimum order quantity for food grade citric acid?
Our minimum order quantity starts at 1 metric ton for standard packaging. For customized packaging or special grades, we can accommodate smaller trial orders starting from 500kg, depending on specific product requirements and production schedules.
How do you handle quality complaints for food grade citric acid?
We have a dedicated after-sales service team that investigates all quality complaints within 24 hours. If any non-conformance is confirmed, we offer replacement products or refunds according to the severity of the issue, and implement corrective actions to prevent recurrence.
What documentation do you provide with each shipment of food grade citric acid?
Each shipment includes a complete documentation package containing Commercial Invoice, Packing List, Bill of Lading, Certificate of Origin, and Certificate of Analysis showing all test results and compliance with relevant standards.
