Effects of Microwave-Assisted Baking on Quality of Gluten-free Cakes and Breads

Gluten-free doughs lack the glutenins and gliadins responsible for dough expansion and strength, inhibiting network formation and reducing the viscoelastic structure of doughs. Microwave baking methods have some advantages over conventional baking methods, including faster heating, time and energy conservation, and greater product volume. They also have some disadvantages, however, including nonuniform heating, insufficient starch gelatinization, gummy texture, lack of color formation, and high moisture loss. A combination of hot air and microwave baking can be used to decrease the moisture loss caused by interior heating. Lack of color formation due to Maillard reaction is another important disadvantage of microwave baking methods. To improve color formation, susceptors that absorb microwave energy, converting it to heat, or a combination of microwave and infrared heating can be utilized. The advantages and disadvantages of baking gluten-free products using different microwave methods and some possible solutions are summarized in this article.


Effects of buckwheat flour, gums and proteins on rheological properties of gluten-free batters and structure of cakes
Yıldız, Eda; Şümnü, Servet Gülüm; Şahin, Serpil (Codon Publications, 2018-01-01)
The main objective of the study is to determine the effects of buckwheat flour concentration and different gum types (xanthan, guar gum) or proteins (soy protein and whey protein) on rheological properties of gluten-free cake batters and physical properties of cakes (weight loss, porosity, specific volume, hardness and macro structure). Gum containing batters exhibited higher apparent viscosities. More uniform distribution of gas cells were observed in whey protein containing samples compared to other batte...

Carob bean flour which contains significant amount of dietary fiber, amino acid and minerals can be an alternative flour to enrich nutritional value of gluten free cakes. The objective of this study was to determine the effects of partial replacement of rice flour by carob bean flour at different concentrations (10%, 20%, 30%) and addition of different types of gums (xanthan gum, and guar gum), on specific gravity and rheological properties of gluten free cake batters. In addition, quality of cakes (weight ...
Effect of sodium silicate on flocculation of hematite with starch in the presence of calcium
Arol, Ali İhsan (2003-01-01)
Sodium silicate is used as a dispersant in the selective flocculation of iron ores with starch as the polymeric floccullant. The mechanism of its dispersive effect on quartz has been reported to be related to its ability to remove coagulants, such as calcium and magnesium ions, from the process water. The interaction between iron oxides and calcium and sodium silicate, which has not appeared in literature, is also an important factor that would contribute to the success of the selective flocculation process...
Effects of legume flours on batter rheology and cake physical quality
Aydoğdu, Ayça; ÖZKAHRAMAN, Canan; Şümnü, Servet Gülüm; Şahin, Serpil (2016-08-25)
Legumes are good sources of proteins, carbohydrates, dietary fibers and minerals. Therefore, legume flours can be a good choice to obtain functional foods. The aim of this study is to examine the effect of legume flours (lentil, chickpea and pea) on rheological properties of cake batter and quality of legume cakes. Wheat flour was replaced partially (20 and 30%) by lentil, chickpea and pea flour to develop legume cake formulations. As quality parameters, weight loss, specific volume, hardness and color were...
Effects of sugar, protein and water content on wheat starch gelatinization due to microwave heating
Şümnü, Servet Gülüm; Bayindirli, L (Springer Science and Business Media LLC, 1999-01-01)
Understanding the interactions between sugar, starch, protein and water, which are the main components of a baked product, will advance the development of high quality, microwaveable products. This paper presents a mathematical model describing the quantitative relationships between water, sugar and protein on the gelatinization of wheat starch following 20 s of microwave heat as determined by differential scanning calorimetry. Addition of sugar decreased the degree of gelatinization of starch due to microw...
