ABSTRACT This invention relates to a process for reducing the color of a glycoside composition, which process comprises contacting a glycoside composition containing colored humins having conjugated unsaturation with hydrogen or a source of hydrogen under hydrogenation conditions for a sufficient time to decrease the color thereof and there- after recovering the glycoside composition of reduced color. Hydrogenation may be carried out by use of an alkali metal aluminum hydride such as lithium aluminum hydride or an alkali metal borohydride, such as sodium borohydride, or by means of catalytic hydrogenation, using a catalyst of nickel, platinum or palladium. The color reduced glycoside is useful as a surfactant for incorporation into a detergent product as a non-ionic surfactant.
