Why Moisture Testing Matters for ODF Films and Tablets

In ODF films, tablets, and other solid dosage forms, moisture content is a critical factor influencing product stability, mouthfeel, and shelf life. Excessive moisture may cause softening, sticking, or microbial risks, while too little moisture can lead to cracking and inconsistent dosing. As a result, moisture analysis is an essential part of both pharmaceutical and functional food production.

1. Why Is Moisture Testing So Important?

• Ensures storage stability: Keeps the product structurally sound across various humidity and temperature conditions.
• Optimizes formulation: Water content affects film flexibility and disintegration time.
• Required by pharmacopeias: All major pharmacopeias include moisture specifications for oral solids.

2. Common Issues in Moisture Testing

• Reliance on subjective methods: Some manufacturers still judge moisture by touch or visual cues.
• Delayed feedback: Traditional oven drying methods are time-consuming and unsuited for in-process adjustments.
• Overlooking batch variability: Inadequate sampling can lead to out-of-spec batches going undetected.

3. Industry Trends

• Fast electronic testing: Modern moisture analyzers replace outdated oven methods for faster turnaround.
• High-sensitivity sensors: Capable of handling ultra-thin ODFs and small tablets.
• Smart calibration: Advanced devices offer auto-calibration for improved accuracy and consistency.
