Frequently Asked Questions
Q1: How do you confirm the product is completely anhydrous?
We use two precise methods to check moisture content: gravimetric analysis and Karl Fischer titration. These tests verify that water content stays below strict limits, ensuring reliable performance in pH-sensitive applications.
Q2: Why is the anhydrous form better for food processing?
Controlling water content prevents variations during production. This guarantees consistent acidity and stable pH in food products, helping maintain uniform quality across batches.
Q3: What are the ideal storage conditions?
Store in a cool, dry place with low humidity. The moisture-proof packaging is designed to prevent absorption and preserve the anhydrous quality of the powder during storage.
Additional Information
Citric acid is a widely used natural acid in the food and beverage industry, serving as an acidulant, preservative, and flavor enhancer. The anhydrous form removes variability caused by water content, offering precise pH control—especially important where minor changes can impact final product quality.
Furthermore, the anhydrous form provides more predictable reactions in formulations. SAM employs strict process controls—including advanced moisture monitoring—to ensure high production accuracy and maintain material integrity. This makes it a consistent and dependable choice for industrial pH regulation.
