The main objective of the study was to determine the effects of different baking ovens and different cake formulations on the degree of starch gelatinization during cake baking. Baking was performed in microwave, infrared-microwave combination, and conventional ovens. Starch gelatinization levels of fat free, 25% fat, and 25% Simplesse (TM)-containing cake samples were examined using differential scanning calorimeter (DSC) and rapid visco analyzer (RVA). Both DSC and RVA results showed that increasing baking time increased gelatinization level for all baking types significantly. It was also found that the effect of fat content on starch gelatinization was different depending on the type of baking. Addition of fat reduced the degree of starch gelatinization in conventional baking. However, fat enhanced the gelatinization in microwave and infrared-microwave combination ovens. Usage of Simplesse (TM) as a fat replacer decreased the starch gelatinization in all types of baking significantly. There was insufficient starch gelatinization in microwave-baked cakes in which the degree of gelatinization ranged from 55% to 78% depending on formulation. On the other hand, it ranged from 85% to 93% in conventionally baked cakes. Combining infrared with microwaves increased degree of starch gelatinization (70-90%).

A Study on Staling Characteristics of Gluten-Free Breads Prepared with Chestnut and Rice Flours Demirkesen, Ilkem; Campanella, Osvaldo H.; Şümnü, Servet Gülüm; Şahin, Serpil; Hamaker, Bruce R. (Springer Science and Business Media LLC, 2014-03-01) The effects of chestnut flour and a xanthan-guar gum blend-DATEM mixture on staling of gluten-free rice breads baked in conventional and infrared-microwave combination ovens were studied. Staling properties of the bread were assessed using mechanical compression (TA), differential scanning calorimetry, X-ray diffraction, and fourier transform infrared spectroscopy (FT-IR). Hardness, moisture loss, and retrogradation enthalpy values for all bread samples increased significantly during storage. FT-IR spectra ...
A study on the effects of different gums on dielectric properties and quality of breads baked in infrared-microwave combination oven Keskin, Semin Ozge; Şümnü, Servet Gülüm; Şahin, Serpil (Springer Science and Business Media LLC, 2007-01-01) In this study, the effects of different gums on dielectric properties of doughs and breads baked in infrared-microwave combination oven were investigated. In addition, the quality parameters of breads formulated with different gums baked in infrared-microwave combination oven were determined. The gums used were xanthan, guar, xanthan-guar blend and kappa-carrageenan. The gums were added to the formulation at 0.5% concentration. The dielectric properties and quality parameters of breads baked in infrared-mic...
The effects of xanthan and guar gums on staling of gluten-free rice cakes baked in different ovens Şümnü, Servet Gülüm; Şahin, Serpil; Meda, Venkatesh (2010-01-01) P>The objective of this study was to determine the effects of different concentrations of xanthan and guar gums and their blends on staling of gluten-free rice cakes baked in microwave-infrared combination oven (MW-IR) and to compare the cakes with conventionally baked ones. Gums were added at concentrations of 0.3% and 1.0%. For preparation of gum blend, 0.5% xanthan gum was mixed with 0.5% guar gum. In order to understand the staling behaviour of cakes, cakes were stored at 22 +/- 2 degrees C for 120 h. X...
THE EFFECT OF DIFFERENT FORMULATIONS ON PHYSICAL PROPERTIES OF CAKES BAKED WITH MICROWAVE AND NEAR INFRARED-MICROWAVE COMBINATIONS Sakiyan, Ozge; Şümnü, Servet Gülüm; Şahin, Serpil; Meda, Venkatesh (2007-01-01) The aim of this study was to determine the effect of different formulations on color and textural characteristics of different cakes during baking in microwave and near infrared-microwave combination ovens. For comparison, cakes were also baked in conventional ovens. Color and hardness for both types of baking schemes were found to be dependent on formulation. Cakes containing Simplesse (TM), a fat replacer consisting mostly of whey protein, baked in microwave and near infrared-microwave combination ovens w...
Development of functional cakes to be baked in microwave-infrared combination oven Özkahraman, Betül Canan; Şümnü, Servet Gülüm; Şahin, Serpil; Department of Food Engineering (2014) The main objective of this study was to develop functional cake formulations to be baked in the microwave-infrared (MW-IR) combination oven by using legume flours. It was also aimed to compare quality of legume cakes baked in MW-IR oven with conventional oven. For this reason, oven type (conventional and microwave-infrared combination oven), baking time (4, 4.5 and 5 minutes), legume flour type (lentil, chickpea and pea) and legume flour concentration (10%, 20%, and 30%) were selected as independent variabl...
