Abstract
A method for assessing the quality of cereals, comprising the steps of preparing a dough by mixing a cereal type whose quality is to be assessed, deforming the dough by mixing so that stress arises in the dough, letting the stress in the dough relax subsequent to the deformation of the dough, registering the stress in the dough during the relaxation and using the stress for assessing the quality, the mixing and the relaxing being carried out in one and the same container.
Claims13
A method of analyzing a cereal for determination of one measure from the group consisting of a measure of baking volume of a dough of said cereal, a measure of extrudability of a dough made from said cereal and a measure of forage functionality of said cereal;
- comprising the steps of:
- preparing a dough by mixing an amount of said cereal with a liquid;
- deforming the dough by mixing the thus-prepared dough in a container so that stress arises in the dough, said stress causing a torque on the container;
- recording the torque in a calculation unit during deformation of the dough;
- determining, in the calculation unit, that a maximum of the recorded torque has been passed;
- interrupting the mixing when the calculation unit has determined that the maximum of the recorded torque has been passed, the interruption of the mixing causing the stress in the dough to relax in said container;
- continuing to record in the calculation unit the torque on the container during the relaxation of the dough, which occurs when the dough is interrupted;
- and
- using the torque recorded during the relaxation of the dough for providing an input signal to a predetermined calculation model in the calculation unit;
- calculating, with the aid of the predetermined calculation model in the calculation unit, a numerical value which constitutes said one measure,
- wherein said calculation model calculates said one measure according to a predetermined linear or non-linear relation between said input signal and said one measure.

- deforming the dough by mixing the thus-prepared dough in a container so that stress arises in the dough, said stress causing a torque on the container;
- recording the torque in a calculation unit during deformation of the dough;
- determining in the calculation unit a first value of the torque, which corresponds to the maximum of the torque recorded during deformation;
- determining in the calculation unit a second value of the torque, which is the value of the torque when all liquid in the dough is absorbed;
- calculating a mixing parameter which is the difference between the first and second values;
- and
- using the mixing parameter for providing an input signal to a predetermined calculation model in the calculation unit;
- calculating, with the aid of the predetermined calculation model in the calculation unit, a numerical value which constitutes said one measure,
- wherein said calculation model calculates said one measure according to a predetermined linear or non-linear relation between said input signal and said one measure.
