Decolorizing Perilla Leaf Polysaccharide(I)-Resin
An orthogonal experime nt design method was used to optimize the decoloration conditions by using resin decoloration technology. The results showed that the optimum decoloration condition of perilla leaf polysaccharid were obtained when resin dosage was 5.0%, pH6.0, decolorization temperature was 70 ℃ and decolorization time was 60 min, the decolorizing rate reached 95.30% and the loss of polysaccharide was 15.50%. The decoloration effects of perilla leaf polysaccharide were well.
