Study Notes

Gelatin Capsule Shell Manufacturing Process

Moisture from high humidity areas can compromise the integrity of gelatin capsule shells
Gelatin is the primary material for capsule shells, derived from collagen of animal sources
Gelatin has different types with varying solubility as a function of pH
Gelatin is used due to its non-toxic, edible, and affordable properties
Optimal moisture content in gelatin is necessary for flexibility and moldability
Issues arise with gelatin due to cultural, religious, and disease transfer concerns
Alternatives to gelatin for capsule shells include plant-based polymers and modified starch
Capsule shell components include polymers, water, colorants, and other additives
Colorants for capsule shells can be dyes or pigments, with pigments being preferred due to their insolubility
