  • The quality attributes of bread made with milk protein (casein, C; whey protein, W) and polysaccharide (sodium alginate, A; ${\kappa}$-carrageenan, K) mixtures were investigated to study the method to suppressing quality deterioration during storage. Bread prepared with the CA mixture had a higher specific loaf volume compared to the control. And bread made with the WA mixture had reduced moisture loss during storage compared to the control. The hardness of control and breads containing protein-polysaccharide mixtures increased during storage, but hardness increased more in the control than the treatments. In terms of crumb color, the breads containing protein-polysaccharide mixtures had higher $L^{\ast}$ values, but lower $a^{\ast}$ and $b^{\ast}$ values than the control. Finally, there were no significant differences in sensory quality among the control and treatment breads. Overall, data indicate that the addition of CA and WA improved the baking quality of bread and retarded staling.

  • The purpose of this study was to investigated quality properties of breads prepared from wheat flour with persimon leaf power. Results showed that the volume of bread was lessened, the weight of bread went up, and baking loss rate diminished as persimmon leaf powder content incremented. The experiment showed that bread was maintained in the low level of springiness and cohesiveness was relatively reduced as time lapsed, whereas 3.0 and 5.0% test group remained significantly high level. There was a rapid increment in chewiness and gumminess, which tended to show significantly low as compared to control group, Results of sensory evaluation showed that the preference scores decreased as the persimmon leaf powder contents increased (p<0.05), flavor made no significant differences up to 3.0% test group, however, 5.0% test group containing elutionsuch as catechin or tannin produced sour and bitter taste so strongly that made if feel uncomfortable with. The augment of content indicated a low prederence in terms of texture, in an overall preference had no significant differences as compared to the control group, and 0.5% test group. Through the results of these of these experiments, we can conclude that the highest quality of persimmon leaf powder content is no more than 0.5% in making bread added with persimmon leaf powder.

  • How do we use onggi, Korean earthenware, for container of dough during fermentation instead of stainless steel container? How does it affect the flavor of bread if onggi tray is used in baking instead of steel tray? We tried to confirm those. As a result, the characteristics of onggi made positive effect on dough in fermenting room. The time, when the temperature of the center in the dough is equilibrated to that of surface on the dough, take shorter in onggi than in stainless steel. It could make the temperature of dough maintained evenly with little deviation, which could result in shorter fermentation time. Volume and surface color of the bread baked on onggi tray were better than on steel tray. The bread baked on onggi tray got higher score on overall acceptability in sensory test than on steel tray. Therefore, if onggi is used during baking, it could produce better quality of bread like making positive effect on fermented foods.

  • This study investigated the quality characteristics of breads made with addition of lotus(Nelumbo nucifera) seeds powder. Breads were prepared with 0, 5, 10, 15 and 20%(w/w) lotus seed powder instead of wheat flour. The moisture, crude protein, crude fat, crude ash and crude fiber contents of the breads increased as the proportion of lotus seed powder increased. The pH of the breads increased as lotus seed powder levels increased. The weight of breads increased with increasing lotus seed powder levels, whereas volume decreased. The specific volumes of breads with lotus seed powder were in the range of $3.59{\sim}4.68\;mL/g$, whereas the control value was 5.12 mL/g. The baking loss rates of breads prepared with 5%, 15% and 20% lotus seed powder were 8.95%, 8.17% and 7.67%, respectively. Lightness (L value) of breads was decreased by addition of lotus seed powder, whereas redness (a value) and yellowness (b value) increased in crumb and crust. Texture measurements showed that hardness and gumminess increased with increased lotus seed powder levels, but springiness decreased. In sensory evaluation, the highest scores for flavor, taste and overall preference were obtained when lotus seed powder content was 10%, and color and texture were the best when 5% of lotus seed powder was added. Thus, addition of $5{\sim}10%$ lotus seed powder may have a role in functional bread preparation, resulting in improved quality.

  • This research was performed to determine the quality characteristics of steamed bread by the number of times through the fermentation process. The number of fermentations varied from 1 to 5 while the steamed bread was prepared by measuring the duration of fermentation, and samples were analyzed in terms of general ingredients, physical properties, in vitro starch hydrolysis, protein digestibility, and sensory characteristics. Five times of fermentation resulted in significantly higher water content (p<0.01), and single fermentation led to the highest protein content (p<0.01). Protein levels decreased as fermentation was repeated. Single fermentation gave the lowest specific bread volume (p<0.05) and it increased with the number of fermentation times. Physical properties also varied with the number of times of fermentation. With more fermentation, hardness, gumminess, and chewiness decreased (p<0.01), whereas resilience (p<0.01) and cohesiveness (p<0.05) increased. In vitro starch hydrolysis was higher with 5 times of fermentation than with single to 3 times of fermentation (p<0.05). Protein digestibility was also higher with 5 times of fermentation (p<0.05). In sensory evaluations, whiteness scores were higher with 4 to 5 times of fermentation (p<0.01) whereas scores for crumb uniformity were lower with 4 and 5 times of fermentation. Moistness (p<0.01), cohesiveness (p<0.01), and chewiness (p<0.05) showed their highest scores with 4 times of fermentation.

  • This study was to investigate the suitability of six domestic wheat cultivars for the Korean-style steamed bread made under optimal conditions. Six wheat flours milled from cultivars of Greu, Kumgang, Eunpa, Taptong Kobun, and Allgreu contained 13.8, 13.7, 13.7, 13.0, 11.7, 11.0% of protein. Control bread was made from blend (protein 10.5%) of 50% high strength and 50% low strength wheat flours milled from imported wheats. The volume of steamed bread made from Kumgang was highest followed by Eunpa, Tapdong, Kobun, Greu, control bread, Allgreu. Especially, the bread qualities of Kumgand and Kobun were superior to the control bread, showing better surface characteristics such as smoothness, glossiness, and whiteness, better shapes and desirable texture. Domestic wheat flours, having medium strength with high protein content above 13.0% were suitable for steamed bread except for Greu. Volumes of steamed bread made from domestic wheat flours were correlated with protein and ash content, flour color (L value), farinograph dough development time and stability, whereas spread ratio, total bread score and overall acceptability were correlated with farinograph dough stability It is concluded that flour quality is more important factor than protein content when domestic wheat flours are chosen for Korean-style steamed bread

  • Functional bread was manufactured with single cell detritus (SCD) of sea tangle. The optimum ingredient formula for SCD bread was determined based on mixture model. Flour and water reduced max weight, strength, hardness and specific loaf volume, whereas the increased SCD reversed the volume change of dough. Flour increased $L^*$ and $b^*$ values of SCD bread, while SCD decreased. Flour and water decreased $a^*$ value, while SCD increased. Max weight, strength, hardness, specific loaf volume, $b^*$ value and water holding capacity (WHC) were linear model on ANOVA table, whereas distance, volume change of dough, $L^*$ and $a^*$ values were nonlinear model. The response constraint coefficient showed that SCD influenced texture of SCD bread more than flour and water did, whereas water influenced the volume change of dough, specific loaf volume and WHC more than flour and SCD did. Moreover, flour influenced color value more than did water and SCD. Distance and $a^*$ value fitted nonlinear model with interaction terms for flour-SCD and water-SCD. Optimum ingredient formula for SCD bread was: flour, 48.25%; water, 30.89%; SCD, 3.86%. Sensory evaluation of SCD bread was a little lower than industrial bread and electrolyzed SCD bread.
