碎米糖化液的脱色工艺研究

Study on the Decoloration Technology of Saccharified Liquid from Broken Rice

目的:探讨碎米糖化液脱色的工艺条件。方法:以活性炭为脱色剂,在单因素基础上进行正交试验,对碎米糖化液进行脱色剂用量、脱色时间、pH和加热温度等因素的考察。结果:碎米糖化液活性炭脱色的最佳工艺为:糖化液加入3%～5%的活性炭后,在70～80℃下脱色35～50 min。结论:本文所建立的脱色工艺简单可行,可为进一步制备注射用葡萄糖的脱色工艺研究提供试验依据。

Objective： To explore the decoloration technology of saccharified liquid from broken rice. Method： Active carbon was used as the decolorizing agent. Single factor experiment based on the amount of deeolorizing agent, deeoloration time, pH value and heat- ing temperature was carried out, and then the orthogonal experiment was performed. Result： The optimum decoloration conditions of saccharified liquid from broken rice were as the follows ：3% -5% active carbon for deeoloration, decoloration time of 35-50min under 70- 80℃. Conclusion： The decoloration technology is simple, practicable and available. It can provide experimental basis for the further research on the deeoloration technology for glucose injections.
