    • The slight increase in absorbance for the capsules in pH 2.3 is due to methylene blue adsorbed on the outside of the microcapsules during the oil-in-oil encapsulation. The amount of sorbed material, as measured by absorbance, is about two orders of magnitude smaller than the encapsulated amount, and it becomes zero -below the UV-vis detection limit- if the capsules are properly washed prior to their introduction in the release medium.
