Title: | Effects of high temperatures and drought during anthesis and grain filling period on wheat processing quality and underlying gluten structural changes | Authors: | Mastilović, Jasna Živančev, Dragan Lončar, Eva Malbaša, Radomir Hristov, Nikola Kevrešan, Žarko |
Issue Date: | 1-Jun-2018 | Publisher: | Wiley | Journal: | Journal of the Science of Food and Agriculture | Abstract: | © 2017 Society of Chemical Industry BACKGROUND: Climate changes do not only affect wheat yield, but also its quality. Information on this topic gathered so far is somewhat contradictory and insufficient. Climate changes also affect wheat indirectly through their influence on the ecosystem, including insects and fungi that affect wheat technological quality. The aim of this study was to examine trends in structural and technological changes of wheat quality under conditions typical of climate changes. With this in mind, three groups of wheat varieties with the same Glu-score were examined in three production years, characterized by different production conditions. RESULTS: A production season characterized by climate change conditions results in lower activity of amylolytic enzymes. What is more, it results in lower content of gluten, higher gluten index value, its decrease after 1 h to 37 °C, lower number of free SH groups and higher content of free amino groups, which result in lower alveograph W, lower farinograph WA and higher extensograph dough resistance. CONCLUSION: Variability in wheat quality produced under different climatic conditions is mainly influenced by the production conditions, including their influence on ecosystem factors. The influence of wheat cultivar genetic predisposition is much less expressed. This indicates that differences among cultivars with different Glu-score might be diminished under the influence of altered production conditions, as a consequence of climate change. © 2017 Society of Chemical Industry. | URI: | https://open.uns.ac.rs/handle/123456789/1583 | ISSN: | 00225142 | DOI: | 10.1002/jsfa.8784 |
