The models developed (based on 84 samples) demonstrate a high percentage of results within the uncertainty of the alveographic method (ISO 27971): 77% of estimated parameter P results. 82% of estimated parameter W results. 87% of estimated parameter P/L results.
The lower performance of these results with respect to those obtained with Mixolab® standard can be explained by the difference in the matrix analyzed with the Alveograph® (white flour) and Mixolab® (whole grain flour). The Rapid wheat+ protocol (20.6 min) can be shortened by removing the dough cooling phase, such that the “rapid wheat” protocol runs for only 13.6 minutes. Combined with the sample water content determination with Infraneo NIR, it is possible to estimate the alveographic parameters in less than 15 minutes. Using the Mixolab® with the Rapid wheat+ protocol (constant hydration = a single test) to analyze unconditioned whole grain gives an estimation of the alveographic results in less than 20 minutes when multi‑parameter equations based on the mathematical study of the comparison of the Alveo‑ graph® and the Mixolab® are used.
