Title: | Prediction of traditionally utilised wheat dough technological quality parameters from Mixolab values: Development and evaluation of regression models | Authors: | Mastilović, Jasna Kevrešan, Žarko Torbica, Aleksandra Janić Hajnal, Elizabet Živančević, Dragan |
Issue Date: | 1-Jan-2014 | Journal: | International Journal of Food Science and Technology | Abstract: | © 2014 Institute of Food Science and Technology. The research was conducted with the aim to investigate the possibility of Farinograph, Extensograph and Amylograph values prediction with linear and/or multiple Mixolab regression models. In total, 163 flour samples were divided based on Machalanobis distances into three sets: prediction, validation and external sample set. Determination coefficients ranged from 0.145 to 0.640 for linear regression models and from 0.279 to 0.739 for multiple regression models. Internal and external validation of developed regression models was conducted. Testing of developed models resulted in a high share of samples for which predicted values were out of the ranges of method official reproducibility and a high share of samples for which predicted values were out of the quality level range obtained by analytical measurement. It was concluded that it is impossible to develop applicable regression models for prediction of Farinograph, Extensograph and Amylograph parameters on the basis of Mixolab values from standard protocol. | URI: | https://open.uns.ac.rs/handle/123456789/6801 | ISSN: | 09505423 | DOI: | 10.1111/ijfs.12601 |
