However, the studies to date using the sorption approach did
not address the kinetics of encapsulation. To successfully use
preformed microbeads for encapsulation, an understanding of the
encapsulation kinetics is required. This would allow the mechanism
of the encapsulation process to be identified as well as the
determination of the rate at which encapsulation occurs. Factors
that influence the rate constant could also be identified and potentially
altered to increase the rate of encapsulation (Meites, 1981).
Additionally, the point at which the encapsulation process reaches
equilibrium could be identified, thereby improving the efficiency of
the process. An understanding of the kinetics of bioactive release
from the microbeads is equally important as it predicts when,
where and how a bioactive will be released. Early release of a
bioactive in either a food product or in the stomach would result
in the bioactive receiving no protection against digestion.
