Title: | Quality parameters of wheat grain and flour as influenced by treatments with natural zeolite and diatomaceous earth formulations, grain infestation status and endosperm vitreousness | Authors: | Bodroža Solarov, Marija Kljajić, Petar Andrić, Goran Filipčev, Bojana Dokić, Ljubica |
Issue Date: | 1-Oct-2012 | Publisher: | Elsevier | Journal: | Journal of Stored Products Research | Abstract: | This study investigated the changes in quality parameters of wheat (mealy and vitreous) non-infested and infested with Sitophilus oryzae (L.) caused by treatments with inert dusts: natural zeolite, two diatomaceous earths from Serbia, and a commercial product enhanced DE Protect-It ®.Inert dust treatments, regardless of infestation status, significantly reduced wheat test weight. This was more marked in mealy (8.3%) rather than in vitreous wheat grain (2.7%). Content of silicon dioxide (SiO 2) in flour from infested lots was significantly higher than in non-infested ones. Treatments with all formulations of inert dusts significantly affected flour water absorption in the non-infested wheat lots. Non-infested high vitreous wheat treated with Protect-It ® showed the highest moisture absorption (61.9 g.100 g -1) in comparison with the control (59.7 g.100 g -1). Significant improvement in dough rheology was observed in the infested soft and hard wheat, particularly through rise of dough energy. Small-deformation tests implied certain dough weakening effects of inert dusts in vitreous wheat but this was not observed in standard large-deformation rheological tests. Application of inert dusts shows an ability to improve some aspects of the technological quality of wheat. © 2012 Elsevier Ltd. | URI: | https://open.uns.ac.rs/handle/123456789/12453 | ISSN: | 0022474X | DOI: | 10.1016/j.jspr.2012.07.001 |
