Overview of the D-Tagatose Stability Test Report
The D-Tagatose Stability Test Report summarizes a long-term study evaluating product consistency, quality, and reliability. Multiple production batches were tested to ensure the data represent actual manufacturing conditions and offer reliable guidance for bulk buyers and industrial users.
The study covers a 36-month period, with assessments at 0, 1, 2, 3, 6, 8, 12, 18, 24, and 36 months. Three independent batches (20190708, 20190710, and 20190715) were tested under controlled storage to confirm consistency across production lots.
At each interval, all critical quality parameters met specification requirements. All time points were qualified, demonstrating stable performance with no significant variation throughout the study.
These results confirm that D-tagatose maintains its physical, chemical, and microbiological integrity during long-term storage, ensuring reliability for global distribution, bulk storage, and industrial use.
Stability Test Plan and Storage Conditions
The D-Tagatose Stability Test Report employs standardized long-term testing protocols widely adopted in the food and ingredient industry to simulate real-world storage environments. These protocols evaluate the performance of D-tagatose over time under controlled temperature and humidity, thereby generating reliable data for shelf-life assessment and commercial applications.
The study used storage conditions of 25°C ± 2°C and 60% ± 5% relative humidity, parameters widely recognized as representative of typical ambient storage conditions for food-grade ingredients. These conditions replicate standard warehouse and transportation environments, thereby enhancing the relevance of the results for global distribution and bulk storage.
In addition to routine physical and chemical evaluations, microbiological testing was performed at specific intervals: the 6th, 12th, 24th, and 36th months. This methodology ensures that D-tagatose remains microbiologically safe throughout storage, thereby providing additional assurance for its use in food, beverage, and nutraceutical formulations.
Key Parameters in the D-Tagatose Stability Study
The D-Tagatose Stability Test Report evaluates a comprehensive set of critical quality attributes to ensure consistent performance, safety, and compliance with food-grade standards. Detailed analytical data collected across 36 months demonstrate the robustness of D-tagatose under long-term storage conditions.
Appearance
Throughout all testing intervals, the appearance of D-tagatose remained consistent and compliant across all three batches. No discoloration, caking, or visible degradation was observed, confirming excellent physical stability over time.
Assay (Content %)
The assay results consistently remained at a high purity level of approximately 99.45% to 99.575% across all batches and time points. Minor variations observed are within acceptable analytical tolerance and indicate no significant degradation trend over 36 months.
Loss on Drying
Loss-on-drying values were tightly controlled at 0.04% to 0.11%, demonstrating low moisture absorption and strong resistance to humidity-related changes. This confirms that D-tagatose maintains stable moisture content under standard storage conditions.
Residue on Ignition
Residue on ignition remained stable at 0.02%-0.06% throughout the study. These consistent values indicate that the inorganic content and overall purity of the product remain unchanged during long-term storage.
Specific Rotation
Specific rotation values were maintained within a narrow range of approximately -6.127° to -6.460°, confirming that the optical and molecular characteristics of D-tagatose remain stable over time without structural alteration.
Melting Point
The melting point of D-tagatose remained consistently within 131.5°C-135.5°C, with most values clustering around 134-135°C. This stability indicates that there is no thermal degradation or polymorphic transformation during storage.
Heavy Metals (Lead)
Lead content remained consistently within the specification limit of ≤ 0.4 mg/kg, with all test results reported as qualified. This confirms that D-tagatose maintains its safety profile with no contamination over time.
Total Bacterial Count
Microbiological analysis showed that the total bacterial count remained negative or within acceptable limits (≤1000 CFU/g) at all tested intervals. This demonstrates strong microbiological stability and ensures suitability for food and nutraceutical applications.
These consistently stable results across all parameters confirm that D-tagatose meets stringent quality requirements and maintains its integrity over extended storage periods, supporting its use in global supply chains and industrial formulations.
