  • This study was carried out to investigate the effects of the addition ratio of BARODON® on the dough volume, moisture content, loaf volume and weight and the sensory characteristics of sprouted brown rice bread. The loaf volume and sensory characteristics of the bread with BARODON® were higher than those without. The moisture content and loaf weight of the bread with BARODON® were lower than those without. Although these results were irregular with increasing amounts of BARODON addition. The sprouted brown rice bread with 0.6% BARODON® gave the best loaf volume and overall acceptance, whereas those with 4.8% BARODON® had the best odor, color and mouthfeel. BARODON® will be very useful as a leavening agent for improving the overall quality of sprouted brown rice bread.

  • Physicochemical properties of bread as influenced by the addition of sweet pumpkin powder (SPP) were investigated. Freeze-dried sweet pumpkin was ground, sieved through a laboratory sieve and a fraction with particles less than $250\;{\mu}m$ was used. Amount of SPP added to the bread was found to affect the bread quality significantly (p<0.05). Loaf volume and weight of the control were significantly higher than others (p<0.05) and decreased significantly (p<0.05) with the addition of SPP. In other words, the enrichment of product with SPP decreased bread volume and weight without significant changes in the moisture content. There were distinctive color changes with the addition of the powder: L- and a-values were reduced but b-value was significantly increased (p<0.05). The hardness, springiness, and gumminess of bread were found to increase with the addition of the powder. Consumer test indicated that bread contained with 3% SPP had the highest overall acceptability score while 1 or 5% addition produced an acceptable quality for the bread.

  • When bread making, the condition of thawing-fermentation for frozen dough were tested in variable temperature, and measured thawing-fermentation time and volume of frozen dough. L-Ascorbic acid (L-Aa) was added in frozen dough for the comparison test of develop volume in bread staling degree of baking bread were measured additive frozen dough which was stoppages in freezing, staling degrees were tested hardness with Rheometer. The test for comparison of thawing-fermentation time in variable temperature was shown the condition of dough conditioner at 3$0^{\circ}C$ was most effective for bread making, Because That condition was required very short time(74 min) But, in this comparison of volume in final products was shown the products in the condition of thawing-fermentation at 3$0^{\circ}C$ was smaller than the products at 5$^{\circ}C$(418 ml). The baking volume of L-Aa additive frozen dough which has under gone thawing-fermentation at 3$0^{\circ}C$, were shown baking volume of 420 ml in 2 weeks storage terms to 100 mg/kg L-Aa additive dough and shown baking volume of 454 ml in 4 weeks storage terms to dough of 200 mg/kg additive weight. Staling degrees of L-Aa additive frozen bread were measured with Rheometer. The hardness of 100 mg/kg L-Aa additive frozen bread was sown low level hardness in 1~2 weeks freezing term, 150 mg/kg L-Aa additive frozen bread was shown low level hardness in 3 weeks freezing term. In 4 weeks freezing term, 200 mg/kg L-Aa additive frozen bread was shown low level hardness compared with non-additive L-Aa frozen bread. In comparison of frozen bread quality, non-additive L-Aa products was better than additive L-Aa products in equality of baking shape and external apparence. But in total quality in external and internal apparence, additive L-Aa products was better than non-additive L-Aa products.

  • This study aimed to investigate quality characteristics of white bread with Tenebrio molitor L. powder (TMP). Because of the proximate composition analysis of the white bread with TMP, the content of protein and crude fat increased slightly in proportion to brown dough, and ash was highest in white breads with 7% added TMP. The bread volume decreased as TMP content increased. The control bread lightness was highest at 78.3, and was negatively correlated with the TMP content. The degree of redness increased with the TMP concentration. The total free amino acid contents were in the following order: white bread with 7% TMP > white bread with 5% TMP > white bread with 3% TMP. With respect to the texture, white bread springiness and cohesiveness with TMP decreased by storage period. The chewiness and brittleness of white breads with TMP decreased significantly with higher concentrations. With extended storage, the bread with TMP added showed lower springiness and cohesiveness; while bread with a lower TMP percentage maintained better chewiness and brittleness. The sensory taste preference was highest for white bread with 3% TMP. Residual appetite scores showed a lower taste preference as TMP content increased and was lowest for white bread with 3% TMP.

  • In this study, we examined the changes in loaf weight, loaf volume and specific volume, moisture content and water absorption, pH and titrable acidity, shape, texture profile and sensory evaluation using sour dough instead of dough conditioner in bread making. The weight and volume of bread tended to increase in the sour dough bread, compared to the control. The pH of bread tended to be lower in the sour dough bread. The control bread had large irregular pores that were fewer in number, while the sour dough bread had small spots and was very dense and even throughout the whole surface. The texture profile of bread such as hardness, cohesiveness, chewiness and brittleness was lower in the sour dough bread. There were no significant differences in the sensory characteristics of the breads, except for the shape of bread. However, the sour dough A bread was better in color, texture, flavor, touch, moistness, taste and overall acceptability, and the sour dough B bread was better in flavor, touch and taste than the control.

  • This study was conducted to investigate the quality characteristics of bread added with four different amounts (0% 3%, 6%, 9%, 12%) of gochujang. The pH, total soluble solid and moisture content of bread added with gochujang were $4.88{\pm}0.05$, $62.00{\pm}0.81%$ and $42.88{\pm}007$, respectively. For amino nitrogen content $224.00{\pm}0.00%$, chromaticity had a L value of $24.46{\pm}0.06$, a value of $10.18{\pm}0.13$, and b value of $7.44{\pm}0.10$. The pH of bread decreased with increasing gochujang content in bread. Total soluble solids of dough increased with increasing gochujang in bread (p<0.001). For fermentation 3% expansion was the highest, and bread volume and specific volume increased with increasing gochujang in bread. For baking loss, 12% was the highest. L values of bread decreased for both crust and crumb with increasing gochujang content in bread, and b values tended to decrease for both. Moisture contents increased with increasing gochujang content (p<0.001). For hardness, cohesiveness, springiness, and gumminess, chewiness of 12% gochujang added to bread showed the lowest value. Evaluation of sensory characteristics of 3% gochujang added to bread was the best. In conclusion, these results confirm that bread with gochujang has good effects on fermentation and preference.

  • This study investigated the quality characteristics of yeast breads with addition of hot air-dried yam powder (HDYP) and freeze-dried yam powder (FDYP), using several physical and sensory examinations. Breads were made of imported wheat flour (IWF) or Korean wheat flour (KWF). HDPY and FDYP were added to the bread formula at three levels of 3, 5, and 7%. The addition of yam powders required an increase of water absorption. As the addition of HDYP/FDYP increased, IWF dough stickiness increased and thus handling property became inferior to the control. Especially, handling property of KWF bread dough containing FDYP was most poor among the dough samples. With HDYP/FDYP, final volumes of bread made from IWF were similar to the control when 3~5% HDYPs were added whereas loaf volumes decreased significantly as the amount of added FDYP increased, indicating volume depressing effect. In bread scoring, texture scores increased when yam powders were added that hardness, chewiness, cohesiveness and guminess of KWF bread increased as the amounts of yam powders increased. The "L" value of IWF bread crumb decreased with the addition of yam powders. From sensory evaluation using acceptability scores, the results gave us that appearance, grain, texture, flavor, taste and overall acceptability of KWF bread could be more improved with the addition of yam powders than those of IWF bread.IWF bread.
