    摘要: A process is disclosed for the production of an alkyl glycoside stable in hue and odor, which comprises the steps of (1) reacting a sugar with alcohol to obtain an alkyl glycoside reaction product containing a higher alcohol, (2) decoloring the alkyl glycoside reaction product with hydrogen peroxide, (3) contacting the decolored alkyl glycoside with a metal/hydrogen complex represented by formula (I)M(BH.sub.4).sub.z (I)wherein M is an alkali metal, Ca, Zn or (CH.sub.3).sub.4 N; andz is 1 when M is an alkali metal or (CH.sub.3).sub.4 N and z is 2 when M is Ca or Zn; to substantially eliminate residual hydrogen peroxide, and then (4) decomposing the remaining metal/hydrogen complex with an acid.
