  • Seven cultivars of hard and soft wheat were evaluated by regression analysis for five bread quality characteristics to determine varietal response to environments. The regression coefficients were used as the measure of adaptability, and determination coefficients were used as the measure of stability by models of Eberhart and Russell. Phenotypic, genotypic and environmental correlation coefficient estimated for 6 characters tested in this experiments. Statistical analyses confirmed the strong influence of environment on five bread quality. A significant positive correlation exists between protein content, sedimentation value, pelshenke value and specific loaf volume. High heritability was found for sedimentation value ($h^2=0.747$), protein content ($h^2=0.557$) and specific loaf volume ($h^2=0.551$).

  • This study investigated the effect of addition of pumpkin on the physicochemical properties of rice sponge cakes. Water retention capacity(WRC) was lowest in control preparations to which no pumpkin flour was added. WRC increased as more pumpkin flour was added and rice flour with 25% of added pumpkin flour showed a WRC of 89.0%. Similar to WRC, alkaline water retention capacity(AWRC) also increased as more pumpkin flour was added and ranged from 69.7% to 80.7%. As the amount of pumpkin flour added increased, the pH increased. Similar to the sedimentation value, the Pelshenke value also increased as the amount of the added pumpkin flour increased. The gelatinization temperature did not vary significantly between the samples(p<0.05). The midline peak height, which is the height of the peak point from the baseline, showed the same tendency with that of the midline peak time, but was not significantly different between samples(p<0.05). Volume was decreased as the amount of the added pumpkin flour increased. The weight of the rice sponge cakes showed significant difference increasing with the increasing added pumpkin flour(p<0.05). There was significant difference as the specific loaf volume decreased with the increasing pumpkin flour(p<0.05).

  • The replacement of wheat flour with 4 to 24% soy fiber FIBRIM(R)1450 was evaluated to determine its effect on the properties of sponge cake. The volume and specific loaf volume decreased as the amount of soy fiber increased. In addition, the protein content and water holding capacity (WHC) were negatively correlated with the specific gravity of batter and the specific loaf volume of sponge cake, whereas there was no correlation between the mixograph characteristics and specific loaf volume of sponge cake in response to the addition of soy fiber. Furthermore, the symmetry and uniformity indices were not influenced by the addition of soy fiber. However, the L values of sponge cake crust and crumb decreased with increasing amounts of soy fiber, whereas a and b values were not affected. Additionally, the hardness, gumminess, and chewiness of the sponge cake all showed positive correlations with the protein content, sedimentation value, WHC and alkaline water retention capacity. Finally, the results of sensory evaluation indicated that external and internal colors, grain, texture, and flavor were not influenced by the addition of soy fiber, but that supplementation with over 20% soy fiber resulted in a slight decrease in taste and overall acceptability.

  • The effects of defatted soy flour on the physicochemical characteristics of dough and bread making properties were studied. Defatted soy flour is added to wheat flour for bread-making in order to maximize the use of isoflavones in the soybean. Different particle sizes of both defatted soy flour and wheat flour were prepared by grinding and sievingwith meshes. In the mixograph test, the addition of defatted soy flour to wheat flour increased the requirement for water and decreased the dough development time. Water absorption rates were also investigated to determine the optimum quantity of water for good dough. As the level of defatted soy flour mixed with wheat flour increased, the sedimentation and P.K. values decreased. In comparison with control, the bread made with defatted soy flour especially had a lower specific loaf volume. Specific loaf volume of wheat flour-defatted soy flour bread prepared (Ed- this is an incomplete sentence, it's only a subject clause, and I don't how what you intend to state). In terms of the staling rate and hardness of the wheat flour-defatted soy flour bread, the increased defatted soy flour had a faster staling rate during storage at 5? than at 25? for 5days. From the result of sensory evaluation, wheat flour-defatted soy flour breads containing up to $4\%$ defatted soy flour were rated as being of high quality.
