  • Oat flour was purchased and investigated for quality characteristics of oat bread. Antioxidant and flour pasting properties of oat flour, and water content, weight, volume, Hunter color value, texture of bread were measured. DPPH radical scavenging capacity (%) of oat extract was 68.49%. Pasting temperature of oat flour ranged between $66.60^{\circ}C$ and $70.93^{\circ}C$. Flour pasting properties of sample added with 10 and 30% oat flour was shown similar results compared with wheat flour. Final viscosity of sample was increased by adding concentration of oat flour (up to 311.65 RVA). Water content (%) of bread was shown increasing trend by adding oat flour. Weight of bread loaf with 100% oat flour was shown higher score than other samples. Volume of loaf by adding oat flour of 10, 30, and 50 % ratio was 550, 450, and 388 mL, respectively. The Hunter color $L^*$ values of bread by adding oat flour was dark compared with wheat bread. Color value of bread added 10% oat flour was similar results with $L^*$ values of bread with wheat flour. The bread added with 20 and 30% oat flours had the higher hardness, gumminess, and chewiness compared with other samples. Cohesiveness of the bread with wheat flour showed higher than that of bread added with oat flour and increased by storage period. The growth of total viable cell was inhibited depending on the concentration of oat flour during storage.

  • 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.

  • Objectives: The purpose of this study was to investigate the effect of white pan bread added with Kamut (Triticum turgidum spp.) on high fat diet (HFD)-induced obese C57BL/6 mice. Methods: The white pan bread or white pan bread with Kamut (BK) were administered for 8 weeks in HFD-induced obese C57BL/6 mice. To evaluate the effect and its mechanisms of BK on obese mice, we measured body weight change, serum lipid profiles, histopathological analysis, and protein expression of CCAAT/enhancer binding protein-α (C/EBPα) in the liver. Results: Administration of BK significantly decreased body weight in HFD-induced obese mice. In addition, BK-administered group significantly reduced serum total cholesterol, glucose, and high-density lipoprotein cholesterol levels compared with the HFD-induced control group. The HFD-induced mice had damaged liver tissue and increased the size of adipose tissue, but BK-administered group attenuated liver damage and decreased the size of adipocyte. Furthermore, administration of BK significantly down-regulated C/EBPα in the liver compared with HFD-fed mice. In particular, BK-administered group has higher inhibited body weight, serum lipid profiles, and C/EBPα expressions than white pan bread-administered group. Conclusions: This study demonstrated that administration of BK attenuated HFD-induced obesity by regulation of C/EBPα than consumption of white pan bread. Therefore, BK could be developed as a bread for prevention of obesity.

  • Jung-Pyun is a traditional steamed rice bread made of fermented rice dough. A series of the Jung-Puyn samples were prepared according to the experimental design of five factors. Factors were fermentation sources(milky rice wine, activated yeast), weight of added water(60, 65, 70, 75% of rice powder), fermentation temperature(30$^{\circ}C$, 40$^{\circ}C$), fermentation times(2,3,4,5,6,12hours) and weight of added baking powder(1, 2% of rice powder). Trained panels judged the steamed rice bread samples to determine the effects of these factors on the sensory characteristics. The results of sensory evaluation revealed that the most preferable steamed rice bread on the overall eating quality was at the 70% adding water and 1% baking powder, 30$^{\circ}C$ for 5 hours incubation made by 1% addition of yeast.

  • The quality characteristics of bread prepared with the addition of dried persimmon peel powder(PPP) were investigated. Visco-elastic characteristics of dough and texture of bread added PPP was examined by rapid visco-analyzer and texture analyzer. The maximum viscosity of the dough with PPP was lower than that of control at 90$\^{C}$. Final viscosity after cooling to 50$\^{C}$, viscosity of control increased to 134 B.U., but that of the dough with PPP showed 13∼37 B.U. As more PPP was added, gluten formation and mixing time dough were longer. Adhesiveness, springness, cohesiveness and chewiness gradually increased as PPP content increased, while the hardness decreased. Lightness value decreased but redness and yellowness values increased with the addition of PPP, especially, the bread made by 15% PPP treatment showed dark brown color. In sensory evaluation of bread, score of color decreased significantly as more PPP was added but overall acceptability was not significant different(p<0.05) between control and 5% PPP treatment. It is considered that the addition of 5% was appropriate for bread making with PPP.

  • Baking characteristics of gluten-free rice bread were investigated, when 20, 30, 40, 50 and $60^{\circ}C$ water was added during mixing. The temperature of the dough before fermentation was affected by the temperature of the water and the mixing time. When $60^{\circ}C$ water was added, the specific gravity of the dough was the highest before fermentation (p<0.01). The specific gravity of the dough after fermentation was 32~39% of the specific gravity of the dough before fermentation. When $50^{\circ}C$ water was added, the volume and the specific volume of rice bread were higher than those in addition of water at other temperatures (p<0.001). In case of adding water of $50^{\circ}C$, the shape of the rice bread showed the largest volume, high appearance and a round shape. After storage for 2 and 24 hours, the addition of water of $50^{\circ}C$ resulted in the lowest hardness and chewiness values of rice bread. The sensory descriptive analysis revealed that when $50^{\circ}C$ water was added, the air cell size, springiness and hardness values of gluten-free rice bread were lower than those in addition of water at other temperatures. There was a difference in the appearance and texture of gluten-free rice bread, when 20, 30, 40, 50 and $60^{\circ}C$ water was added during mixing.

  • The interrelation between physicochemical properties of milled rice and retrogradation of rice bread during cold storage was examined to compare the varietal difference in maintenance of rice bread quality. Twelve rice materials showed big varietal difference on physicochemical properties of rice starch such as amylose content(0.0~29.2%), gel consistency(20~98mm), and alkali digestion value(2.0~7.0). Rice bread made from milled rice of Jungwonbyeo, AC 27 and IRAT 177 exhibited soft texture and late retrogradation of rice bread during cold storage(4$^{\circ}C$). The amylose content of milled rice was closely associated with gel consistency negatively and with springiness of rice bread positively. The retrogradation of rice bread texture during cold storage was correlated with gel consistency of rice flour positively and with alkali digestion value of milled rice negatively.

  • 빵 부패미 생물에 대한 녹차추출물의 항균활성을 조사하고 녹차가루를 첨가한 찐빵의 저장 중 항균효과를 알아보고자 하였다. 사용된 세균 3종류인 Bacillus subtilis ARCC 6633, Bacillus pumilus KCTC 3348, Bacillus cereus IFO 12113과 곰팡이 Aspergillus niger KCCM l1239 모두 GTE 1% 이상에서 우수한 항균력을 가지고 있으며, 생육이 억제됨을 확인하였다. GTE의 열 안정성은 넓은 온도 범위(50~20$0^{\circ}C$)에서 열을 가하지 않았을 때와 동일하게 항균력이 유지되었고, pH 사용범위 (4~9)에 관계없이 동일한 환으로 항균력을 나타내었다. 녹차를 첨가한 찐빵을 $25^{\circ}C$에 저장하면서 총 곰팡이 수와 총 세균 수를 측정한 결과 대조군, GTP 1%, 3% 첨가군 모두 저장 3일째에 곰팡이가 나타났으나 GTP 5% 첨가군에서는 저장 3일째에 나타났다. 총 세균 수는 저장 3일 이후 $10^{7}$ CFU/g을 넘어 부패가 진행 중이었으나 GTP 3%는 5일째에, GTP 5% 첨가군은 7일째에 $10^{7}$ CFU/g을 나타났다. 그러므로 찐빵에서의 녹차의 항균 효과에 따른 저장기간 연장은 녹차가루 첨가량 5% 이상의 수준에서 가능하리라고 추측된다.
