  • The quality characteristics of breads made by adding levels of 30%, 60%, and 100% aloe gel were investigated. The 60% aloe gel sample had a larger dough volume than the control dough. Also, the loaf volume and specific volume of the bread made with 60% aloe gel were larger than those of the control bread. The pasting temperature increased gradually with the increasing amounts of substituted aloe gel as compared to wheat flour with water added$(66.5{\pm}12^{\circ}C)$; the wheat flour with 100% aloe gel had a pasting temperature of $90.7{\pm}1.1^{\circ}C$. Peak viscosity decreased gradually with increasing amounts of aloe gel when compared to the wheat flour with water added. Setback also was decreased gradually with the increasing amounts of aloe gel as compared to the wheat flour with added water. From the setback decrease it is suggested that the aloe controlled retrogradation of the bread during short-term storage. The crumb color of the bread made with the aloe gel was not significantly different to that of the control bread, and the color of the crumb was yellow-white. Bread hardness decreased gradually with increasing amounts of the substituted aloe gel. However, bread gumminess and chewiness increased gradually with increasing amounts of aloe gel. The springiness of the bread made with 100% aloe gel was lower than that of the control bread. With regard to flavor and taste, the bread made with 100% aloe gel produced a green-like odor and had a bitter taste. The mouth feel of the breads made with aloe gel was considered soft and moist. The overall acceptabilities of the breads made with 30% and 60% aloe gel were not significantly different from the control bread, but the bread made with 100% aloe gel had a green smell and bitter taste. Yet accordingly, the results indicate that functional and health products with improved quality could be developed by adding aloe gel to breads and cakes.

  • This study was carried out to investigate the quality of white pan breads as affected by various amounts of Terminalia chebula Retz (TC) powder, in which the breads were prepared with 0, 2, 4, and 6% TC powder. The samples and a control bread were compared in terms of bread quality characteristics, including pH, baking loss rate, loaf volume index, moisture content, TBARS values, texture, color, and sensory qualities in order to determine the optimal amount of TC powder in the formulation. The pH levels of the bread samples containing TC powder ranged from 5.30 to 5.44, while the control bread had a pH of 5.68. The loaf volume index values of the samples prepared with 2~6% TC powder were lower than that of the control. After 7 days storage, the moisture content of the control bread had decreased by 14.4%, while the moisture contents of the breads with added TC powder had decreased by approximately 8~10%. The breads with TC powder had lower TBARS values as compared to the control bread. For texture characteristics, hardness increased with the addition of TC powder, and was especially increased in the sample containing 6% TC powder. Cohesiveness and springiness, however, decreased with the addition of TC powder. For color, lightness of the bread crust and crumb decreased with the addition of TC powder, whereas redness and yellowness increased. In terms of sensory quality, the bread containing 2% TC powder was preferred over the control bread, as estimated by appearance, crust color, taste, and overall quality, while the 6% TC bread had the lowest preference scores. These results suggest that the addition of 2% TC powder to white pan bread had optimal effects for improving shelf-life and enhancing bread quality.

  • The purpose of this study was to help promote the consumption of rice by substituting rice powder for wheat flour in bread preparation and examining the effect of rice powder particle size in baked rice bread samples. Several experiments were carried to analyze and compare the quality characteristics of prepared samples of wheat flour and rice powder breads. The loaf volume index of the wheat flour bread was 6.34, and the indices of the rice powder bread samples, which were made from powder milled through 20, 35, and 45 mesh (S1, S2 and S3), were 5.37, 5.56, and 5.85, respectively. These data indicated that the loaf volume index of the rice powder bread was lower than that of the wheat flour bread, but the volume of the rice powder bread increased as the particle size of the rice powder became finer. According to texture analysis results using a rheometer, the hardness value of the wheat flour bread was $1.34{\times}10^3\;g/cm^2$, and values of S1, S2, and S3 were $1.74{\times}10^3\;g/cm^2$, $1.57{\times}10^3\;g/cm^2$, and $1.47{\times}10^3\;g/cm^2$, respectively. Therefore, S3, which was made from the finest powder among the rice powder samples, showed the lowest level of hardness. No significant differences were observed for springiness, cohesiveness, and gumminess among the bread samples. However, the wheat flour and rice powder breads had significant differences for bread crumb color. The L-value of S3(76.20) was similar to that of the wheat flour bread(77.22). but the L-values of S1(70.30) and S2(71.21) were lower than that of the wheat flour bread. In terms of redness and yellowness, the values of the rice powder breads were significantly different from those of the wheat flour bread. In terms of overall preference, the sensory evaluation results indicated that S3 was significantly the more preferred and the wheat flour bread was the least preferred among the bread samples. This study also investigated texture changes and mold occurrence in bread samples stored at $25^{\circ}C$ for 5 days. From the 3rd day of storage, bread texture became harder in all samples however, S3 showed the least level of change among the rice powder breads. The occurrence of mold began to increase abruptly from the 4th day of storage, and S2 and S3 showed mold numbers that were 2-fold greater than those of S1 and the wheat flour bread.

  • Functional foods play an important role in daily diet, human health and the food industry. Hemp was reported to have many advantages for nutritional and medicinal usage. In this study, extruded hemp-rice (EHR) flour, containing 30% hemp, was mixed with the wheat flour to create bread loaves at the concentrations of 5, 10 and 15%. Bread made from 100% wheat flour (with no added EHR flour) was used as a control. The physical parameters, including expansion ratio, specific volume and crust/crumb color were evaluated separately. In addition, changes in hardness of the bread during storage at ambient temperature for 3 days were also studied. The results showed that 10%-EHR bread exhibited the highest hardness value, while 15%-EHR bread presented the lowest. The bread containing EHR flour had lower specific volume and bigger air cells compared to the control. Moreover, the crust and crumb color of EHR-containing bread was significantly darker than those of the control. In this study, the 15%-EHR bread showed higher specific volume, lower hardness and bigger air cell structures.

  • This study was conducted to investigate the effect of the addition of moroheiya powder on the baking qualities of the bread. Three different powder concentration levels of $0.2\%,\;0.5\%\;and\;1.0\%$ were added to flour to make the bread. The volume of the bread dough containing moroheiya powder tended to be increased compared to that of control during the fermentation period. The percentage of baking loss of the bread containing moroheiya powder tended to be less than that of control. In the texture analyzer measurement, the hardness of the bread was significantly increased by adding the moroheiya powder Springiness, gumminess and brittleness of the bread tended to increase and were all higher in the bread containing $0.5\%$ moroheya powder than in the other breads. In sensory evaluation, the bread containing $0.2\%$ moroheiya powder showed a similar tendency with control and showed the best scores, especially in taste.

  • The purpose of this study was to prepare bread added with sea buckthorn (Hippophae rhamnoides L.) berry powder (SBBP) (1, 3, and 5%) using a straight dough method. The quality and antioxidant characteristics of the bread were analyzed. The results indicated that the pH value and dough raising power of the dough decreased and the moisture content of the bread added with SBBP increased compared to that without the SBBP. The crust color of the bread did not change significantly. However, the crumb lightness value decreased and the redness and yellowness value increased respectively to the concentration of the SBBP. The texture measurement indicated that the hardness, gumminess, and chewiness of the bread increased with the addition of the SBBP. The total polyphenol content of the bread supplemented with the SBBP was increased (4.60~16.14 mg GAE/g) compare to the control (1.67 mg GAE/g). Dose-dependent, significant-high DPPH (26.86%) and ABTS (42.52%) radical scavenging activities were observed in the bread with the addition of the SBBP up to 5%. Based on these results, the optimum amount of the SBBP to add for baking bread would be 3% and the SBBP could be considered a functional agent.

  • This study is to find out the effects of the qualify of the breads made from Korean and imported wheat flour respectively after adding chitosan, by examining the dough making, the bread making properties, the Physicochemical properties of the breads. The low polymerized chitosan (M. W. : 37,000) was added respectively 1, 3 and 5% in the form of 10% lactic acid aqueous solution. The Korean wheat bread had 4% more water, 3% more sugar, 0.5% more salt, 3% more margarine and 1.5% more yeast per 100% to wheat flour added than the imported wheat bread. The bread volume for the two groups stayed the same. The water absorption in the chitosan added group was increased more greatly than in the control group, however, pH was reduced. In case of color among all wheat bread groups the ‘L’ value appeared to be higher in the imported wheat bread groups, and the ‘b’ value appeared to be higher in the chitosan added group.
