Response Surface Methodology (RSM) was used to study the effects of reaction temperature, the mass fraction of tea polysaccharide and the VC/Na 2 SeO 3 ratio (M/M) on the particle size of composite. The complex was characterized by UV, Zeta potential, XRD and FT-IR. When the mass fraction of tea polysaccharide is 4‰ and the VC/Na 2 SeO 3 ratio (M/M) is about 5:1 at 50°C, the particle size of the complex can be less than 70 nm.
