Study Notes
Gelatin Blends for Capsule Production
- High gel strength blends of bone and pork skin gelatin are used for hard capsule production.
- Bone gelatin forms a tough, firm, but hazy and brittle film.
- Pork skin gelatin adds plasticity and clarity, reducing haze in capsules.
Recent Gelatin Developments
- "Green" (fresh) bones are now commercially used for Type B gelatin production.
- Processing is similar to aged bone gelatin, resulting in indistinguishable final products.
- Acid-bone gelatin, prepared from bone using acid extraction, is a newer development.
- Acid-bone gelatin shows an altered isoelectric point (pH 5.5-6.0) and intermediate film characteristics.
- Acid extraction reduces gelatin processing time.
Gelatin Specifications
- Gelatin used is USP grade.
- Additional specifications are required by capsule manufacturers, concerning Bloom strength, viscosity, and iron content.
