Understanding Kegunaan Citric Acid Monohydrate Properties

Citric acid monohydrate (C₆H₈O₇·H₂O) is the hydrated crystalline form of citric acid, characterized by its white crystalline appearance and high water solubility (1.54 g/mL at 20°C). Unlike anhydrous citric acid, this variant contains 8% water by molecular weight, enhancing its dissolution rate in manufacturing processes. The compound maintains optimal stability between pH 2-6 and decomposes above 175°C without toxic byproducts. Pharmaceutical-grade monohydrate purity exceeds 99.8%, while food-grade material conforms to FCC V standards. Manufacturers produce over 3.2 million metric tonnes annually through Aspergillus niger fermentation, with global production efficiency increasing 18% since 2020.

Core Industrial and Consumer Applications

The multifaceted kegunaan citric acid monohydrate
spans numerous sectors. In food production, it serves as a pH regulator in beverages (40% market share), antioxidant in packaged foods, and emulsifier in processed cheeses. Global beverage manufacturers utilize 120,000 tonnes annually for pH control in carbonated drinks alone. Pharmaceutical applications include anticoagulant properties in blood preservation (3.5% w/v concentration) and effervescent tablet formulations. Industrial cleaning sector consumption grew 7.3% YoY due to its descaling efficiency - 15% solutions remove calcium deposits 50% faster than vinegar. Emerging applications include biodegradable chelating agents replacing EDTA and eco-friendly metal surface treatment solutions.

Technical Advantages Over Alternatives

Performance comparisons reveal citric acid monohydrate's superior technical profile against common substitutes:

Limescale removal efficiency measured at equivalent 10% solutions on standardized calcium carbonate deposits after 30 minutes exposure

Manufacturer Pricing and Quality Comparison

The citric acid monohydrate price fluctuates based on production method and purity grade. Current bulk pricing (25kg bags) ranges from $1,050-$1,800/tonne:

Industrial buyers prioritizing pharmaceutical applications typically incur 22-25% premium for USP-grade material, while bulk food processors minimize costs through long-term contracts fixing prices at 85-92% of spot market rates.

Customized Formulation Capabilities

Leading suppliers now offer tailored citric acid monohydrate formulations meeting specific requirements:

• Particle Engineering: Micronized powders (5-50μm particle size) for rapid dissolution in cold-process applications
• Co-Processed Blends: Citrate buffer systems pre-mixed with disodium phosphate for pH stabilization (±0.1 variance)
• Encapsulated Formats: Delayed-release pellets for controlled chelation in industrial cleaners
• Impurity Profiling: Heavy metal content reduction to <1ppm for electronics manufacturing

Formulation adjustments can enhance functionality: adding 0.5% silica flow agent improves powder handling properties by 40%, while specialized crystallization techniques increase bulk density to 0.85 g/cm³ for volumetric dosing efficiency.

Implementation Success Cases

European beverage conglomerate B secured 18% production efficiency gains by switching to micronized citric acid monohydrate, reducing dissolution time from 12 to 4 minutes in cold-fill operations. A major dairy processor eliminated calcium lactate crystals in shredded cheese using a patented citrate blend, resolving a $1.2 million annual product return issue. Biomedical manufacturer C achieved 99.97% endotoxin-free status in IV solutions by implementing pharmaceutical-grade monohydrate with specialized QC protocols, passing FDA inspections with zero observations.

Securing Quality Supply When You Buy Citric Acid Monohydrate

Procuring reliable citric acid monohydrate requires stringent verification protocols. Industry best practices include:

1. Supplier audits confirming fermentation-based production (avoiding synthetic oxalic acid byproducts)
2. Third-party validation of USP/FCC/BP monographs for purity
3. Lot-specific heavy metal certificates (Pb <2ppm, As <1ppm)
4. Accelerated stability testing (40°C/75% RH for 3 months) confirming moisture retention below 8.8%

Strategic inventory planning should account for typical delivery lead times: 20-45 days for Asian suppliers versus 7-14 days for domestic stock. Implement incoming material testing for oxalate content (max 100ppm), sulfated ash (max 0.05%), and identity confirmation via FTIR spectrometry.

FAQS on kegunaan citric acid monohydrate

Q: What are common applications of citric acid monohydrate?

A: Citric acid monohydrate is widely used as a preservative and flavor enhancer in foods/beverages. It acts as an antioxidant and pH regulator in cosmetics and pharmaceuticals. It also removes scale in cleaning products and industrial descaling agents.

Q: How much does citric acid monohydrate cost?

A: Prices range from $1 to $3 per kilogram when purchased in bulk quantities. Costs vary based on purity levels, supplier volume discounts, and shipping fees. Small quantities (under 1kg) may cost 2-4 times more per unit weight.

Q: Where can I buy citric acid monohydrate?

A: Reliable sources include chemical suppliers like Sigma-Aldrich, e-commerce platforms (Amazon, Alibaba), and specialty food ingredient stores. Industrial buyers can procure it in bulk from manufacturers such as Jungbunzlauer or ADM. Always verify quality certifications.

Q: Is citric acid monohydrate safe for food use?

A: Yes, it's globally approved as GRAS (Generally Recognized As Safe) by the FDA and EFSA. In foods, it regulates acidity and prevents spoilage. Typical usage levels in consumer products pose no health risks unless consumed excessively.

Q: Can citric acid monohydrate be substituted with anhydrous citric acid?

A: Yes, but adjust quantities: monohydrate contains 8% water, while anhydrous is 100% acid. Use 10% more monohydrate for equivalent acid strength. Monohydrate dissolves better for cleaning, while anhydrous is preferred for dry mixes.
