Application of Citric Acid Monohydrate
- Food and Beverage Industry
◼ Suitable for beverages: Balances sweetness and acidity, delivering a refreshing sour taste without bitterness.
◼ Improves processed meat quality: Inhibits spoilage bacteria, maintains meat color, and extends shelf life.
◼ Suitable for baked goods: Used as a leavening agent to control gelation in jellies and jams.
Why it’s suitable: It’s key to achieving superior flavor, extending shelf life, and maintaining stable food production quality. - Pharmaceuticals and Personal Care
◼ Pharmaceutical pH buffer: Stabilizes the pH value of syrups, effervescent tablets, etc.
◼ Mild pH adjuster for cosmetics: Used in creams, lotions, shampoos, etc., to improve stability.
Why it’s suitable: Ensures product stability and compatibility with sensitive formulations． - Industrial and Cleaning Applications
◼ Chelating agent for cleaning: Softens water and enhances cleaning power, preventing scale formation.
◼ Environmentally friendly descaling agent: Reduces scale buildup in industrial systems, boilers, and cooling systems
Why it’s suitable: Provides an effective and biodegradable alternative to harsh chemicals, supporting sustainable operations.
Selection Guide – Anhydrous vs Monohydrate Citric Acid
◼ Anhydrous Citric Acid: Suitable for formulations requiring low moisture, fast dissolution, and precise pH control; ideal for instant powders, effervescent tablets, and moisture-sensitive products needing stability and extended shelf life.
◼ Preferred Citric Acid Monohydrate: Suitable for standard food, beverage, and industrial applications where moisture sensitivity is not critical; It provides reliable acidity adjustment and flavor enhancement for conventional formulations such as beverages and jams.
Certificates / Compliance
◼ This product is manufactured under an ISO 9001 quality system and complies with relevant regulatory requirements.
◼ COA, SDS/MSDS, and related certificates are available upon request.
