FAQ

1. Transportation Conditions of Size 2 Gelatin Capsules
Size 2 gelatin capsules, like other hard empty gelatin capsules, are sensitive to environmental conditions such as temperature, humidity, and light. During transportation, maintaining the physical integrity and chemical stability of the capsules is essential to ensure product quality.
Key transportation guidelines include:
Temperature control: Ideally, gelatin capsules should be transported at 15–25°C. Exposure to high temperatures may cause softening, sticking, or deformation, while low temperatures can make them brittle.
Humidity control: The relative humidity (RH) should be maintained between 35%–65%. Excess moisture can cause the capsules to swell or stick, while extremely dry conditions may lead to cracking.
Packaging: Capsules are typically sealed in moisture-resistant, anti-static PE bags and packed in high-barrier cartons or fiber drums. The packaging should protect the capsules from light, moisture, and physical damage.
Transport mode: Air-conditioned trucks or containers are preferred, especially in extreme climates. Shock and vibration should be minimized to avoid breakage or powder leakage if pre-filled.
Handling: During loading and unloading, capsules should be handled with care to avoid pressure or crushing.
2. Storage Conditions
To maintain the gelatin capsules' mechanical and chemical properties over their shelf life, proper storage is crucial.
Recommended storage conditions:
Temperature: 15–25°C
Relative humidity: 35%–65% RH
Ventilation: Storage areas should be well-ventilated and away from strong odors, chemicals, or volatile substances that could affect the gelatin.
Light: Store away from direct sunlight to avoid discoloration or degradation.
Stacking: Avoid stacking heavy items on top of capsule cartons to prevent deformation.
First-In-First-Out (FIFO): Capsule batches should be used in the order of production to ensure freshness.
If stored under these recommended conditions, size 2 gelatin capsules typically have a shelf life of 24 months.
3. Physicochemical Testing Items
To ensure quality, safety, and consistency, a comprehensive set of physicochemical tests is performed on gelatin capsules. These tests comply with pharmacopeial standards such as USP, EP, or ChP.
Main testing items include:
Appearance
Capsules should be cylindrical with a smooth surface, free of cracks, dents, or deformations.
Color should be uniform with no stains or spots.
Size and Dimensions
Capsule body and cap should meet specific diameter and length specifications for size 2.
Tolerances are strictly monitored to ensure compatibility with filling machines.
Moisture Content
Typically controlled within 13.0%–16.0% to maintain elasticity and prevent brittleness.
Measured using Karl Fischer titration or thermogravimetric methods.
Disintegration Time
Capsules should completely disintegrate in 0.5% hydrochloric acid (simulating gastric fluid) within 10 minutes, unless otherwise modified.
Microbial Limits
Total aerobic microbial count (TAMC): ≤1000 CFU/g
Total yeast and mold count (TYMC): ≤100 CFU/g
Absence of pathogens: E. coli, Salmonella, S. aureus must not be detected
Loss on Drying
Used to measure water and volatile contents; helps assess moisture stability.
Heavy Metals & Residual Solvents
Must comply with pharmacopeial limits to ensure safety.
Gel Strength (Bloom Value)
Indicates the gelling ability of gelatin; typically around 150–250 Bloom for capsule-grade gelatin.
Viscosity
Important for the encapsulation process; ensures proper shell formation.
Colorant & Additive Content
If colorants or opacifiers (e.g., titanium dioxide or iron oxide) are used, their concentrations must meet regulatory standards.
Conclusion
Proper transportation and storage of size 2 gelatin capsules are essential to maintaining their functionality and safety. Meanwhile, rigorous physicochemical testing ensures that the capsules meet pharmacopeial and customer-specific quality standards. These practices are critical to guarantee consistent capsule performance for pharmaceutical and nutraceutical applications.
