The present invention relates to a method for improved demineralization of fermentation broths, including the steps of providing a solution comprising one or more oligosaccharides, carrying out a first membrane filtration and preferably being a microfiltration or ultrafiltration, a second membrane filtration of the permeate of the first membrane filtration and a first nanofiltration step; with a sub-step of concentration and/or a sub-step of diafiltration. Moreover, the present invention is directed to an improved purification of fine chemicals from a fermentation broth.

A process for the preparation of C4 to C24 alkyl polyglycosides by the use of an enzyme to react C4 to C24 alkyl glycoside with a glycosyl donor containing monosaccharide residues, wherein the C4 to C24 alkyl polyglycosides have a mole-average degree of polymerization (mean DP) of the glycoside chains of greater than 1.5 units. The C4 to C24 alkyl polyglycosides are particularly useful in personal care formulations.
