The aim of the present study is to investigate the effects of heat-treated liquid whole egg (LWE) on cake batter rheology (shear rate-viscosity and shear rate-shear stress) and quality characteristics (moisture loss, color, porosity, texture, and specific volume) of baked cakes. LWE was pasteurized at different levels which were 60-68 degrees C for 2 and 5 min. Cake batter and baked cakes were prepared using both untreated and treated LWE, and rheological properties and quality characteristics were measured, respectively. Flow behavior index (n) and consistency index (K) of the control batter group were found significantly different from the treated LWE cake batters. Heat treatment of LWE showed an unfavorable effect on porosity (decrease from 59% to 49%), hardness (increase from 1.1 to 1.4 N), and specific volume (decrease from 3.6 to 3.4 cm(3)/g) of the baked cakes because of having less volume and a stiffer structure of heat-treated LWE batter.

EFFECTS OF SEMPERFRESH(TM) AND JOHNFRESH(TM) FRUIT COATINGS ON POSTSTORAGE QUALITY OF ANKARA PEARS Şümnü, Servet Gülüm (Wiley, 1994-08-01) Pears were coated with different concentrations of Semperfresh or with Johnfresh edible coatings after storage for five months at 0C to determine the effects of coatings on poststorage quality. Coating levels were effective for extending the poststorage life and delaying ripening. Both Semperfresh and Johnfresh treated pears had better color, firmness, ascorbic acid, titratable acidity, soluble solid retention than control pears. Although Semperfresh was effective for the reduction of respiration and weight...
Determination of pasteurization treatment of liquid whole egg by measuring physical and rheological properties of cake cream Uysal, Reyhan S.; BOYACI, İSMAİL HAKKI; Şümnü, Servet Gülüm (Wiley, 2019-06-30) The aim of this study is to determine whether liquid whole egg (LWE) is pasteurized by measuring the physical and rheological properties of cake cream. The applicability of the method was demonstrated on the creams prepared using unpasteurized and pasteurized LWE (ranging from 60 to 68 degrees C for 2 and 5 min). Foaming capacities (%) of the LWE samples were measured. Physical (specific gravity) and rheological properties (shear rate-shear stress and shear rate-viscosity) of the creams were measured. A sta...
The effects of gums on macro and micro-structure of breads baked in different ovens Ozkoc, Semin Ozge; Şümnü, Servet Gülüm; Şahin, Serpil (Elsevier BV, 2009-12-01) In this study, the effects of gums on macro and micro-structure of breads baked in different ovens (infrared (IR)-microwave combination and conventional) were investigated by the help of image and SEM analysis, respectively. The gums used were xanthan, guar, K-carrageenan and xanthan-guar blend. The gums were added to the formulation at 0.5% concentration. As a control, no gum added formulations were used. Results of Image analysis demonstrated that xanthan-guar gum blend addition improved bread quality wit...
Effects of different batter formulations on physical and chemical properties of microwave and conventionally fried chicken fingers Barutçu Mazı, Işıl; Şahin, Serpil; Department of Food Engineering (2009) The main objective of this study was to determine the effects of batters containing various flour types and frying methods on physical and chemical properties of chicken fingers. To determine the effects of different flour types, 30 % of the corn and wheat flour mix in control batter was replaced with chickpea, rice or soy flours. Frying was performed in microwave oven at 365 W (70 %) power level and at 1801°C for different times. Samples were also fried in a conventional fryer at 1801°C for comparison. T...
Effect of polydextrose-substitution on the cell structure of the high-ratio cake system Hicsasmaz, Z; Yazgan, Y; Bozoglu, F; Katnas, Z (Elsevier BV, 2003-01-01) Effect of polydextrose-substitution on the cell structure of the high-ratio cake system was investigated in terms of the bubble size distribution and foam drainage time of the cake batter, and the cake height, true and bulk densities, porosity, cell size and shape distributions of the cake crumb. Sugar-replacement levels were 0%, 25%, 50%, 75%, and 100% of the sugar content of the conventional high-ratio cake formulation.
