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

摘要

A method and a device for rapid testing of the quality of cereals, grits and flours measures the aggregation of gluten. The sample to be tested in aqueous solution/suspension containing mineral salts and/or acids and/or liquors in a specific amount in a sample cup is stirred with an electrically driven stirring paddle and the resistance opposed to the paddle by the sample during the stirring process is measured, the torque loads acting on the rotatably mounted electric drive motor being measured from the beginning of the stirring process using extensometric gauges, the measurement being completed once the maximum rotating torque is reached and the measuring process being monitored, controlled and analyzed by software.
