The migration of amino acids or peptides from solution into
microbeads has previously been shown to be a partition process
where the extent of the compounds migration is influenced by
the affinity of the compound for the whey microbead. The more
hydrophobic the amino acid or peptide the greater the mass of
compound that resided within the microbead phase at equilibrium
(O’Neill et al., 2014). The data in Table 1 expands on this by showing
that the rate of migration is also influenced by this hydrophobic
interaction, the stronger the affinity the faster the rate of uptake.
