Abstract: A vegetable particulate food product produced from plant parts containing starch and having at least one constituent that can be removed by means of water that is reduced by 20 to 90 wt % of the original content in comparison with the native plant part, and a method for producing such a food product.

Abstract: A method of preparing potato fibres includes the steps of: a) washing potatoes; b) optionally removing solid impurities and rinsing water adhering to the potatoes; c) grinding the potatoes into a pulp; d) separating potato fruit water; e) removing starch and optionally residual potato fruit water in order to obtain raw fibres; f) refining the raw fibres; g) mixing in potato fibres which have previously been dried; and h) drying the fibres; as well as potato fibres obtainable by that method and use thereof.

Abstract: A method of obtaining vegetable proteins and/or peptides is disclosed that includes the steps of: a) preparing a vegetable starting material containing proteins and/or peptides in an aqueous matrix; b) optionally eliminating solid components from said aqueous matrix and/or clarifying said aqueous matrix; c) isolating the proteins and/or peptides from the aqueous matrix by adsorption on at least one ion exchanger membrane made of a synthetic polymer; d) optionally rinsing the ion exchanger membrane in order to remove impurities; e) desorbing the proteins and/or peptides from the ion exchanger membrane with at least one eluent; f) isolating the proteins and/or peptides from the eluent; and g) optionally drying the isolated proteins and/or peptides; and a protein, peptide and/or mixtures thereof prepared in accordance with the method, and uses thereof.
