Methods: Taking activated carbon as decoloring agent, orthogonal experiment was carried out on the basis of single factor. The dosage of decoloring agent, decolorizing time, pH and heating temperature were investigated. Results: The optimum conditions for decoloration of activated carbon from broken rice saccharified liquid were as follows: decolorization was performed at 70-80 ℃ for 35-50 min after adding 3% -5% activated carbon into the saccharified solution. Conclusion: The decolorization process established in this paper is simple and feasible, which can provide experimental basis for the further preparation of decolorization process of glucose for injection.
