Abstract: Tara polysaccharide is a kind of galactose, which has a very important application value for us. We mainly studies the tara polysaccharide extract from tara seeds. By the single factor experiment, we optimized four factors including the activated carbon particle quality, decolorization time, decolorization temperature and decolorization times. The best optimum conditions were under activated carbon particles of 0.6 g, decolorization time of 45 min, decolorization temperature of 45℃, decolorization times of 3, the decolorization rate can be achieved 50.21%, at the same time, and the retention rate of polysaccharide was 90.39%.

Key words: tara polysaccharide, decolorization, single factor experiments, orthogonal optimization
