Abstract

A high-efficiency and low-loss method was established, for decoloration of perilla leaf polysaccharide by using active charcoal. With the decoloration method of activated charcoal, the decoloration process of perilla leaf polysaccharide was optimized by using response surface methodology. The best processing conditions was determined as 0.58% activated carbon, pH 6.0, and decolorization temperature 50 ℃, decolorization time 15 min. Under those conditions, the decolorizing rate and the loss rate of polysaccharide reached 99.99% and 5.05%, respectively. The results suggested that the proposed method had ideal effect in decoloration of perilla leaf polysaccharide.
