Partitioning refers to the distribution of a compound between
two immiscible phases. In the experiments presented the whey
microbead and the release medium are the two phases. At equilib-
encapsulated could be used to increase the total percentage encapsulation.
In addition, it was shown that the entrapment of the
compounds within the microbeads was occurring via a process of
partition. Egan, O’Riordan, O’Sullivan, and Jacquier (2014) encapsulated
charged peptides in preformed whey protein microbeads
using a similar sorbent method. Adjusting the pH of peptide solutions
to facilitate an electrostatic interaction between the peptides
and the microbead resulted in high levels of peptide encapsulation.
