The present invention relates to a process for preparing a whole grain cereal based extract having improved suspension properties. The process comprises the steps of: (i) providing a whole grain cereal; (ii) subjecting the whole grain cereal to a first grinding; (iii) subjecting the ground whole grain cereal to an hydrolysis of the macromolecular elements providing a modified whole grain cereal; (iv) separating a soluble fraction of the modified whole grain cereal from an insoluble fraction of the modified whole grain cereal; and (v) subjecting the insoluble fraction of the modified whole grain cereal to a second grinding and/or enzymatic modification obtaining a cereal based fraction having improved suspension properties, and comprising particles having a particle size of at the most 100 μm, such as at the most 50 μm, e.g. at the most 30 μm; and (vi) reincorporating at least part of the cereal based fraction obtained from step (v) into at least part of the soluble fraction obtained from step (iv) obtaining the whole grain cereal based extract.
