In this study, the influences of microwave frying and various flour types on microstructure of batter coatings were investigated. Control batter formulation contained only wheat and corn flour. To determine the effects of different flour types, 30% of the corn and wheat flour mix was replaced with chickpea, rice or soy flours. Frying was performed in microwave oven at 365 W (70%) power level for 1.5 min after bringing the oil temperature to 180 +/- 1 degrees C. Samples were also fried in a conventional fryer at 180 degrees C for 1.5 and 5.0 min for comparison. Microwave fried samples had higher specific bulk volume and porosity values and also smoother inner surface as compared to conventionally fried samples. Porosity values of different batter formulations were in the range of 0.425-0.484 in 1.5 min microwave fried chicken samples and 0.348-0.392 in 5.0 min conventionally fried ones. Microwave fried samples had comparable or lower hardness values than the conventionally fried ones depending on the flour type used in batter formulation. Microstructure of fried batter was different for different batter formulations. Microwave fried control and chickpea flour containing batter provided formation of larger gas cells on the outer surface. Soy flour containing batter resulted in smallest size gas cells for both frying methods.

Effects of different ovens and enzymes on quality parameters of bread
Keskin, Semin Özge; Şümnü, Servet Gülüm; Department of Food Engineering (2003)
The main objective of the study was to determine the effects of enzymes on quality of breads baked in halogen lamp-microwave combination, microwave and conventional oven. It was also aimed to determine the optimum processing conditions in these ovens. In the first part of the study, as independent variables, baking time, baking temperature for conventional oven; microwave power for microwave oven and microwave power and halogen power for combination oven was used. Weight loss, specific volume, firmness and ...
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 1801°C for different times. Samples were also fried in a conventional fryer at 1801°C for comparison. T...
EFFECTS OF SUSCEPTOR, COATING AND CONVENTIONAL BROWNING APPLICATIONS ON COLOR AND CRUST FORMATION DURING MICROWAVE BAKING
Şahin, Serpil; Şümnü, Servet Gülüm (2002-01-01)
The effects of different browning treatments on the crust color and crust hardness of microwave baked breads were investigated. Microwave oven was operated at 20%, 30% and 40% powers for 3.5-5.5 minutes. As a control, breads were baked in a conventional oven at 200 degrees C for 12 minutes. After microwave baking, breads were browned or conventional browning times increased, crust hardness and weight loss of breads increased. When susceptors were used, desired browning and hardness were obtained on the bott...
Influence of fat content and emulsifier type on the rheological properties of cake batter
Sakiyan, O; Şümnü, Servet Gülüm; Şahin, Serpil; Bayram, Göknur (2004-11-01)
The effects of fat content and emulsifier type on the rheological properties of cake batter have been investigated by using a parallel-plate rheometer. The apparent viscosity of cake batter with five different fat concentrations (0, 12.5, 25, 37.5, and 50%) and two types of emulsifier, namely Purawave and Lecigran, was studied as a function of the shear rate. In addition, the time dependency of different cake formulations was investigated. It was found that cake batter with different fat concentrations and ...
Usage of enzymes in a novel baking process
Keskin, SO; Şümnü, Servet Gülüm; Şahin, Serpil (Wiley, 2004-04-01)
In this study, the effects of different enzymes (a-amylase, xylanase, lipase, protease) on quality of breads baked in different ovens (microwave, halogen lamp-microwave combination and conventional oven) were investigated. It was also aimed to reduce the quality problems of breads baked in microwave ovens with the usage of enzymes. As a control, bread dough containing no enzyme was used. Specific volume, firmness and color of the breads were measured as quality parameters. All of the enzymes were found to b...
