Characterization of a food-based enteric coating for capsules and its compatibility with an alternative sealing method.

Efficiency of a new protein-based enteric coating for capsules was studied. Coating physical-chemical properties were compared to those obtained from a well-known methacrylate-based enteric coating (Eudragit). Swelling in simulated gastric fluid (SGF) was 20 times higher than for Eudragit films.
