Volume ratio did influence the encapsulation maximum (Emax)
of tryptophan, at equilibrium an Emax of 16 ± 1.1% was obtained
at a volume ratio of 0.13 while at a volume ratio of 0.6 the Emax
was significantly (p 6 0.05) higher at 45 ± 1%. The Emax for tryptophan
in microbeads increased with increasing volume ratio and
was significantly different at each volume ratio (Table 1).
