dc.description.abstract | Due to its negative impact on the yield and quality of stored grains, the aim of this
research was to study the influence of Rhyzopertha dominica F. on rheological properties
of wheat flour obtained from grains infested by examined pest. A rheological
laboratory device - Mixolab was employed in order to simulate the production process
of bread (from the beginning of dough mixing until the end of bread baking).
Wet gluten and gluten index, as significant flour quality parameters, were also determined.
The flour of wheat varieties Planeta and Kruna was used in these experiments.
The samples of both varieties infested with R. dominica (infested samples)
were characterized and compared to their uninfested counterparts (control samples).
Infested samples expressed a lower gluten index content, greater weakening of the
gluten network upon mixing and heating, as well as lower starch gelatinization viscosity
in comparison to control samples. Changes in the gluten index value were
more pronounced in Planeta variety which was characterized with a higher degree
of infestation. Determined changes in rheological properties of infested wheat were
mainly dependent on a degree of infestation. However, a varietal dependency on
the intensity of changes in technological quality cannot be neglected. | sr |
dc.description.abstract | Zbog negativnog uticaja na prinos i kvalitet uskladištenog žita, cilj istraživanja je
proučavanje uticaja Rhyzoperta dominica F. na reološke osobine pšeničnog brašna
dobijenog od zrna infestiranog ispitivanom štetočinom. Za simulaciju proizvodnje
hleba (od zamesa do krajnjeg proizvoda – hleba) korišćen je reološki laboratorijski
uređaj – Mixolab. Takođe, određen je i sadržaj vlažnog glutena i gluten indeks koji
su značajni parametri kvaliteta brašna. U eksperimentu je korišćeno brašno sorti
pšenice Planeta i Kruna. Ispitani su uzorci obe sorte infestiranih sa R. dominica (infestirani
uzorci) i upoređeni sa odgovarajućim neinfestiranim uzorcima (kontrola).
U poređenju sa kontrolnim uzorcima, infestirani uzorci pokazali su manji sadržaj
glutena, veće slabljenje glutenske mreže prilikom mešenja i zagrevanja, kao i
manji viskozitet i želatinizaciju skroba. Promene u vrednosti gluten indeksa bile su
izraženije kod sorte Planeta kod koje je utvrđen veći procenat infestacije.Utvrđene
promene u reološkim osobinama infestirane pšenice zavisile su, prvenstveno, od
stepena infestacije pšenice. Međutim, intenzitet promena tehnološkog kvaliteta
uslovljen je i uticajem sorte, koji ne može biti zanemaren. | sr |
