A reputable safe capsule gelatina factory will typically implement continuous monitoring systems throughout manufacturing, with automated data recording to ensure process consistency and facilitate thorough batch tracing when necessary.

Quality assurance laboratories within manufacturing facilities conduct real-time testing during production, with particular attention to viscosity measurements, bloom strength determination, and microbiological monitoring. These in-process controls allow for immediate corrective actions when parameters deviate from specifications, preventing the production of substandard material and ensuring consistent quality across production batches.

Factors Influencing the Quality of Capsule Gelatina

The functional performance of capsule gelatina depends on several key physicochemical properties that must be carefully controlled during manufacturing. Bloom strength, measured in Bloom grams (g), indicates the gel strength and molecular weight distribution of the gelatin. Pharmaceutical applications typically require bloom strengths between 150-280 g, with higher values providing greater mechanical strength but potentially slower dissolution rates.

Viscosity represents another critical parameter, influencing capsule shell formation, filling machine performance, and dissolution characteristics. Optimal viscosity ranges between 25-45 mPa·s for most pharmaceutical applications, measured as a 6.67% w/w solution at 60°C. Both bloom strength and viscosity are influenced by the raw material source, extraction conditions, and manufacturing methodology, requiring careful balancing to achieve desired performance characteristics.

Additional quality factors include:

• Clarity and Color: Determined by the efficiency of filtration and purification processes, with higher clarity indicating superior purification. Color measurements using Hunter Lab or CIE systems ensure batch-to-batch consistency.
• Moisture Content: Typically maintained between 10-15% to ensure proper capsule shell flexibility and prevent brittleness. Precise control prevents microbial growth while maintaining optimal mechanical properties.
• Isoelectric Point: Differing between Type A (pH 7-9) and Type B (pH 4.8-5.2) gelatin, influencing compatibility with active ingredients and dissolution profiles.
• Film-Forming Properties: Essential for capsule shell integrity, influenced by gelatin molecular weight distribution and amino acid composition.

Hong Kong's Center for Food Safety regularly assesses gelatin quality parameters, with 2022 surveillance data indicating that gelatin from established best bone gelatin products supply sources consistently met pharmacopeial specifications across all critical parameters. This consistent performance underscores the importance of selecting suppliers with robust quality management systems and extensive experience in pharmaceutical-grade gelatin manufacturing.
