The technology for bleaching of the starch glycoside surfactant was studied by using hydrogen peroxide as the major decoloring agent, coupled with magnesium sulfate, sodium silicate and EDTA as additive agents. The technic of decoloration was optimized through the orthogonal experimentation. Under the optimal experimental conditions, the resulting products exhibit good stability. After 72h stability test, only a little change of 1.01% by U-2001 spectrophotometer at absorbance 470 nm. The absorbance was observed by compared with the products before decoloration and after. The main composition and structure of the starch glycoside surfactant were analyzed by infrared spectrum (IR) and gas chromatography (GC). The experimental results show that the technics of decoloration for the starch glycoside surfactant are feasible and simple which may be useful for practical applications.
