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 be effective in reducing the initial firmness and increasing the specific volume of breads baked in microwave and halogen lamp-microwave combination ovens. However, in conventional baking, the effects of enzymes on crumb firmness were seen mostly during storage. The color of protease enzyme added breads were found to be significantly different from that of the no enzyme and the other enzyme added breads in the case of all type of ovens.

Optimization of microwave- infrared roasting of hazelnut Uysal, Nalan; Şümnü, Servet Gülüm; Şahin, Serpil (Elsevier BV, 2009-01-01) In this study, the possibility of using microwave-infrared combination oven for roasting of hazelnut was investigated. in addition, regression models for the responses: L* value, a* value, textural properties and moisture content of hazelnuts were obtained and the optimum roasting conditions were determined by using response surface methodology. Conventionally roasted hazelnut at 150 degrees C for 20 min was considered for comparison. For hazelnuts, 2.5 min roasting time at 90% microwave power, 60% upper ha...
Bread baking in halogen lamp-microwave combination oven Keskin, SO; Şümnü, Servet Gülüm; Şahin, Serpil (Elsevier BV, 2004-01-01) The main objective of the study was to compare the effects of halogen lamp-microwave combination baking on quality of breads with other baking methods (conventional, microwave and halogen lamp baking). It was also aimed to improve the quality of microwave baked breads by using combination oven. Weight loss, specific volume, firmness and color of the breads were measured as quality parameters. Halogen lamp-microwave combination oven reduced the conventional baking time of breads by about 75%. Microwave heati...
Comparison and modeling of microwave tempering and infrared assisted microwave tempering of frozen potato puree Seyhun, N.; Ramaswamy, H.; Şümnü, Servet Gülüm; Şahin, Serpil; Ahmed, J. (Elsevier BV, 2009-06-01) Microwave tempering and infrared assisted microwave tempering of frozen foods were simulated by using finite difference method. The effects of microwave power and infrared power on tempering were discussed. Three different microwave power levels (30%, 40%, and 50%) and three different infrared power levels (10%, 20%, and 30%) were used. The increase in microwave power level and infrared power level decreased tempering times. The change of heat capacity and the dielectric properties of frozen potato puree wi...
Transport and related properties of breads baked using various heating modes Şümnü, Servet Gülüm; Şahin, Serpil; Rakesh, Vineet (Elsevier BV, 2007-02-01) Physical properties of breads during baking were measured using three different heating modes of microwave plus infrared (MIR), microwave plus jet impingement (MJET) and jet impingement (JET) in two different commercially available microwave combination ovens. Breads baked in JET oven were significantly different from the breads baked in other ovens with respect to their specific volume and moisture content. Transient values of dielectric constant, dielectric loss factor, specific bulk volume, porosity, the...
Drying of carrots in microwave and halogen lamp-microwave combination ovens Şümnü, Servet Gülüm; Öztop, Halil Mecit (Elsevier BV, 2005-01-01) Carrot slices were dried by using microwave, halogen lamp-microwave combination and hot-air drying. Microwave and halogen lamp-microwave combination drying were applied after carrots were dried to 0.47 kg moisture/kg dry solid by hot-air drying. Drying time, rehydration capacity and colour of the carrots dried by different methods were compared. The increase in microwave oven power level decreased the drying time. Microwave drying at the highest power and halogen lamp-microwave combination drying reduced th...
