Abstract:

The purpose of this paper is to investigate a new type of resin of chitosan cerium encapsulated green tea extract microspheres (RCCM-GTE) prepared by the reversed-phase suspension cross-linking polymerization and study the scavenging activity against DPPH free radical. The results showed that RCCM-GTE was a type of deep brown-yellow spherical resin with smooth surface and it presented uniform and narrow particle size distribution as determined by the Laser Particles Sizer. The Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES), Fourier Transform Infrared Spectroscopy (FT-IR) and differential scanning calorimetry (DSC) study demonstrated that there was cerium existing in RCCM-GTE. The polyphenolic compounds existed in RCCM-GTE and the total content of polyphenolic compounds encapsulated in RCCM-GTE was found to be 92.550±1.145 μg/g. It is considered that the good antioxidant activity of RCCM-GTE was the comprehensive results of the action of tea polysaccharide-protein conjugate, polyphenolic compounds, cerium and Schiff base chitosan. Investigation showed that a lot of extracts coming from agriculture and food industry contain reactive components of polyphenolic compounds and polysaccharides. It can be effective in protection of human beings from free radical damage if these extracts are directly or after the extraction and purification added to food as natural food antioxidant or they are prepared micospheres reacted with some biopolymers through coordination as a health food. Then the emerging area of research on encapsulating GTE in chitosan cerium resin must have a broad developing prospect.
