Abstract: A process for producing coagulated leguminous protein fractions of MW>14, comprising: initial charging of fruit juice; coagulation of the leguminous protein; removal of a leguminous protein fraction whose majority has an MW of from >14 kD to approx. 600 kD; optionally, washing the coagulated leguminous protein fraction thus obtained; and optionally, drying the leguminous protein fraction, and to the use of the leguminous protein fraction as a food, food additive, medicament additive, animal feed, in cosmetics, as industrial protein, and/or as an adhesive.

Abstract: A method of preparing a coagulated plant protein fraction with a medium molecular weight of between 14 to 97, by providing fruit juice in aqueous solution; precipitating a high-molecular-weight plant protein fraction whose bulk has a molecular weight of from above 100 to 600, by adjusting an acidic pH and/or a temperature above room temperature, and mechanically separating the fraction precipitated thus; precipitating a medium-molecular-weight coagulated plant protein fraction under warm conditions by treating, at pH 2 to 7, and between 60 to 90° C., the solution obtained after separation of the high-molecular-weight plant protein fraction and mechanically separating the medium-molecular-weight coagulated plant protein fraction with a molecular weight of between approximately 14 to 97, with the bulk of the molecular weight distribution being between 20 to 60.

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.

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.
