Major research subjects in our laboratory include elucidation of chemical structure and
physical characteristics of various biomaterials for their novel utilization in foods
and other industrial products such as cosmetics.
The biomaterials are derivatized by chemical, physical, and enzymatic means
to create or improve thier functional properties with value added.
Among the biomaterials, biopolymers are currently main subjects for researches.
Not only the molecular but three dimensional structure of the biopolymers
determining physical and physicological functions are ivestigated by using
various analytical processes. Through investigating the relations between structural
features and functional properties of the polymers, the mechanisms
in polymeric functions in matrices of foods and other products could be revealed.
The current research projects include ..
(1) Nano-encapsulation of biofunctional
ingredients with starch or it dextrins for increasing water solubility and bioavailability
of physical treatments substituting chemical modification of starch
(3) Structural derivatization of hyaluronic acid to
improve its stability against chemicals and physical forces
(4) Novel utilization of the rice bran extracts
as biofunctional ingredients in cosmetics
(5) Germination of brown rice for the production of bioactive components.
