Zusammenfassung:PCT No. PCT/FR97/00249 Sec. 371 Date Aug. 7, 1998 Sec. 102(e) Date Aug. 7, 1998 PCT Filed Feb. 7, 1997 PCT Pub. No. WO97/29115 PCT Pub. Date Aug. 14, 1997Process for preparing surfactant, which comprises contacting cane trash, maize by-products, sorghum by-products, barley by-products, rice by-products, fruits, chicory pulp, tubers or cynara for at least 5 seconds with a hydrolysing agent selected from an aqueous acid solution at between 20 and 150 DEG C. and an enzymatic hydrolysing composition of a plant material at between 20 and 90 DEG C. to obtain a sugar syrup, freeing the sugar syrup from any solid residues and contacting the residue-free sugar syrup with a C4-22-alcohol at a temperature of between 20 and 150 DEG C., preferably between 30 and 110 DEG C., until a solution of surfactant glycosides is obtained, and separating the surfactant glycosides from this solution.
