Citric Acid Monohydrate (C₆H₈O₇·H₂O) is the hydrated form of citric acid, containing one molecule of water of crystallization. It is a naturally occurring organic acid produced through fermentation of carbohydrate sources such as molasses or corn starch. Unlike the anhydrous version, monohydrate offers slightly lower concentration per gram but is more economical and perfectly suited for most food, beverage, and industrial applications where precise moisture control is not critical. Moon Bright Resources supplies premium-grade citric acid monohydrate with 99.5-100.5% purity, manufactured under strict quality controls. Our product meets multiple international standards and is trusted by beverage manufacturers, food processors, pharmaceutical companies, and industrial formulators worldwide.

FAQ – Frequently Asked Questions
Q1: What is the difference between citric acid monohydrate and anhydrous?
A1: The difference is water content. Monohydrate contains 7.5-9.0% water of crystallization, making it slightly less concentrated per gram but more economical for most applications. Anhydrous contains no water (≤0.5% moisture), offering higher concentration per gram and better stability in dry formulations. For standard food, beverage, and detergent applications, monohydrate is the preferred and more cost-effective choice. For pharmaceutical effervescent tablets, dry powder blends, or moisture-sensitive formulations, anhydrous is recommended. Citric acid powder chemical supplier
Q2: Is citric acid monohydrate safe for food and beverage use?
A2: Yes, citric acid is Generally Recognized as Safe (GRAS) by the FDA and approved as food additive E330 worldwide. Our monohydrate citric acid meets USP, BP, and FCC standards, ensuring it is suitable for food, beverage, and pharmaceutical applications. It is produced through natural fermentation and contains no harmful impurities. Halal and Kosher certifications are available upon request. We provide Certificate of Analysis (COA) with every shipment. Citric acid monohydrate wholesale price , Eco-friendly cleaning acid supplier , Citric acid monohydrate wholesale price per kg
Q3: Do you offer OEM / private label packaging?
A3: Yes, Moon Bright Resources provides full OEM services for citric acid monohydrate. We can package under your brand name with custom-printed bags (1 kg to 25 kg, or FIBCs), custom mesh size specifications (coarse, standard, or fine), and your choice of food grade, pharmaceutical grade, or technical grade. Minimum OEM order quantity is 10 metric tons. We also offer custom repackaging for distributors, private label with multilingual labeling, and shrink-wrapped pallets for retail-ready displays. Halal and Kosher certified packaging available. Citric acid monohydrate CAS number
Q4: What is your minimum order quantity (MOQ)?
A4: MOQ is 1 kg for sample orders, 25 kg (one bag) for small commercial orders, and 10 metric tons for wholesale pricing. Bulk orders of 20 metric tons or more (full container) qualify for discounted rates. For OEM private label orders, MOQ is 10 metric tons. Pharmaceutical grade (USP/BP) minimum is 5 metric tons. Full container load is typically 20-25 metric tons depending on packaging type.
Q5: How should citric acid monohydrate be stored?
A5: Store in original tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and moisture. Keep away from strong oxidizing agents, alkalis, and metals (corrosive to mild steel). Ideal storage temperature is 15-30°C with relative humidity below 65%. Under proper conditions, shelf life is 24-36 months. Citric acid is hygroscopic — exposure to humidity may cause caking or clumping. Partially used bags should be resealed immediately. Store away from incompatible materials including nitrates, chlorates, and permanganate Citric acid fine powder supplier
