What are the steps for preparing empty gelatin shells?

The correct sequence for manufacturing empty gelatin capsules includes:

• Dipping – Stainless steel pins are dipped into a gelatin solution.
• Spinning – The gelatin-coated pins are rotated to evenly distribute the material.
• Drying – The gelatin shells are dried to the correct moisture content.
• Stripping – Dried shells are removed from the pins.
• Trimming – Capsule ends are cut to size.
• Joining – The body and cap are assembled.
• Polishing – Capsules are cleaned and polished for a finished appearance.

What does the viscosity of gelatin indicate in capsules?

The viscosity of gelatin is a measure of its molecular chain length, which affects the mechanical properties and handling of capsules.

What is Bloom strength, and why is it important?

Bloom strength measures the gel strength of gelatin. It determines the firmness of the gelatin and is crucial for ensuring capsule integrity.

What is the iron content limit in gelatin?

The maximum allowable iron content in gelatin is NMT (Not More Than) 15 ppm to prevent impurities from affecting capsule quality.

What is the source of Type A and Type B gelatin?

• Type A gelatin – Derived from acid-treated animal skins.
• Type B gelatin – Derived from alkaline-treated bones, such as green bone.

How is gelatin treated to slow down solubility?

Gelatin is treated with formaldehyde to retard solubility, making the capsule dissolve more slowly in the digestive system.

What is Rotofill used for?

Rotofill is a specialized capsule filling machine designed to fill capsules with liquids accurately.

What are vegetable capsules made of?

Vegetable-based capsule shells are made from Hydroxypropyl Methylcellulose (HPMC), which is suitable for vegetarians and those with gelatin allergies.

What is an opacifier, and what is commonly used as one?

An opacifier makes capsule shells opaque to protect sensitive ingredients from light. The most commonly used opacifier is Titanium dioxide (TiO₂).

What are the common packaging methods for capsules?

• Blister packs – Capsules are sealed between plastic and foil.
• Strip packaging – Capsules are enclosed between layers of foil or plastic film.
