Application of Monosodium Citrate
Core Identity & Primary Application
Monosodium Citrate is a mildly acidic citrate salt used where gentle buffering and controlled acidity are required, offering a softer pH effect than di- or trisodium citrate.
Application-Specific Advantages
- Beverages & Ready-to-Drink Formulations
◼ Key Role: Adjusts acidity and stabilizes pH in beverage systems with low tolerance to stronger alkaline salts.
◼ Why Choose: Preferred when minimal impact on flavor profile is required. - Food Processing & Seasonings
◼ Key Role: Contributes to acid–salt balance in savory foods and compounded flavor systems.
◼ Why Choose: Enables fine pH tuning without excessive sodium input or sharp taste changes. - Nutritional & Fortified Products
◼ Key Role: Acts as a buffering component to support formulation stability.
◼ Why Choose: Selected for applications needing controlled buffering with moderate sodium contribution. - Pharmaceutical & Oral Liquid Systems
◼ Key Role: Maintains pH stability in liquid dosage forms.
◼ Why Choose: Used for its predictable buffering behavior and regulatory compatibility.
Monosodium Citrate Purity & Safety
Crafted from high-grade citric acid, it meets strict food safety standards, with minimal impurities to ensure compatibility in sensitive formulations like infant food.
