Method and device for rapid testing of the quality of cereals, grits and flours by measuring the aggregation of gluten

摘要

The invention concerns a method and a device for rapid testing of the quality ofcereals, grits and flours by measuring the aggregation of gluten, whereby thesample to be tested in aqueous solution/suspension containing mineral saltsand/or acids and/or liquors in a specific amount in a sample cup is stirred withan electrically driven stirring paddle and the resistance opposed to the paddleby the sample during the stirring process is measured, the torque loads actingon the rotatably mounted electric drive motor being measured from the beginningof the stirring process by means of extensometric gauges, the measurement beingcompleted once the maximum rotating torque is reached and the measuring processbeing monitored, controlled and analyzed by software.
