DİYET LİFİ İLE ZENGİNLEŞTİRİLMİŞ GLUTENSİZ KEK HAMURLARININ YÜKSEK GENLİKLİ SALINIMLI KAYMA ANALİZİ (LAOS) İLE REOLOJİK KARAKTERİZASYONU.

In this study, the effect of orange fiber (dietary fiber source) addition on gluten free batters from rice flour and buckwheat flour rheological properties was investigated by using LAOS method. The effect of different amount dietary fiber on some quality parameters (textural properties, specific volume) of gluten free cakes were also investigated. Gluten-free cake batters were formulated by replacing buckwheat flour with orange fiber at different levels (0%, 4%, 8%, 12% and 16%). Results showed an increase in storage (G') and loss (G") moduli values with the addition of dietary fiber in the gluten free batter. All gluten-free cake batter samples showed linear viscoelastic properties at small strain amplitudes but rheological properties enters the non-linear region by increasing strain amplitude. Increaing the dietary fiber amount caused to increase in specific volume (P <0.05) of gluten free cakes and decrease in hardness value (P <0.05) of cakes. [ABSTRACT FROM AUTHOR]
