Abstract:
Objective: To optimize the decolorization technology of activated carbon for the plant pigment in Bletilla striata polysaccharide.Methods: Using L 9 (3 4) orthogonal test with activated carbon as the decolorizer, the amount of activated carbon, decolorization temperature, decolorization liquid pH and decolorization time were investigated.The decolorization rate and polysaccharide retention rate were investigated.The decolorization rate and polysaccharide retention rate were taken as the indices.Results: The optimum decolorization technology was as follows: the amount of activated carbon was 1.0%, the decolorization temperature was 40 ℃, the pH value was 5 and the decolorization time was 30 min.Under those conditions, the decolorization rate of Bletilla striata polysaccharide was 91.3% and the retention rate of polysaccharide was 80.6%.Conclusion: The selected decolorization technology of activated carbon can make Bletilla striata polysaccharide get the best decolorizing effect.
