보리를 제빵에 이용하기 위하여 새쌀보리와 새찰보리가루를 첨가한 복합분의 반죽물성과 제빵 특성을 조사하였다. 호화특성의 최고점도는 새쌀보리 복합분에서는 증가하였지만 새찰보리 복합분의 경우는 감소하였다. 반죽의 안정도는 10% 복합분에서는 대조구와 동일하였으나 30% 복합분에서는 대조구에 비해 크게 감소하였다. Extensograph 특성 조사 결과 대조구에 비하여 복합분의 신장도는 감소한 반면 저항도는 증가하였다. 빵의 무게와 부피는 보릿가루 첨가량이 증가할수록 무게는 증가하고 부피는 감소하였다. 새쌀보리 첨가구보다 새찰보리 첨가구, 무발아보리 첨가구보다 발아보리 첨가구의 비용적이 더 컸다. 빵 속살의 L값은 10%, 20% 첨가구는 대조구와 차이가 없었다. 조직감 특성은 새쌀보리의 경우 10% 첨가구는 경도의 증가를 제외하고는 대조구와 차이가 없었고, 새찰보리의 경우 10% 첨가구는 모든 항목에서, 20% 무발아새찰보리 첨가구는 응집성을 제외한 탄력성, 점착성, 파쇄성 및 경도에서 대조구와 유의적 차이를 보이지 않았다. 관능평가 결과 10% 첨가구는 대조구와 유의적 차이가 없었으며, 20% 첨가구도 제빵품질에 큰 영향을 주지 않고 첨가할 수 있는 수준이라 판단 되었다. 반죽의 물성과 빵의 품질 특성 조사 결과 메성보리인 새쌀보리는 발아시킴으로써 제빵적성이 좋아졌으나 찰성보리인 새찰보리는 발아시킴으로써 제빵적성이 감소되었다.

This study was conducted to evaluate the physicochemical characteristics of pound cake made of substituted flour with different amount of $\beta-glucan$ i.e. 3, 6 and $9\%$ respectively. $\beta-glucan$ is a functional food material produced from Agrobacterium sup. R259 KCTC 10197BP. The specific gravity and pH of dough were found to be increased according to $\beta-glucan$ content Rheological property such as adhesiveness of dough has no difference between control and $\beta-glucan$ added groups. The pH of baked pound cake was not significantly different between control and $\beta-glucan$ groups. The volume of baked pound cake wag not significantly different between control and the ones with up to $6\%$ $\beta-glucan$, Lightness (L), redness (a) and yellowness (b) value of Hunter color system of cake crumb were not significantly different among teated groups, except a value of crust in $9\%$ $\beta-glucan$ group. the moisture content of cake increased according to $\beta-glucan$ content. Hardness by texture analyser was decreased with increasing $\beta-glucan$ content although cohesiveness wag not changed in β$\beta-glucan$ groups, compared with the control. Sensory evaluation results showed that the mean scores of over·all acceptability in 3 and $6\%$ $\beta-glucan$ were higher than that of control. Based on these results, the addition of $\beta-glucan$ to pound cake up to $6\%$ was considered to be desirable especially in terms of texture.

This study was conducted in order to investigate the properties of bread making and quality improvement when wheat flour is replaced with whole waxy sorghum flour. Sorghum flour, which was prepared with two types of milling methods of pin mill and ultra fine pulverization, was used at different levels ranging from 10, 20 and 30%, respectively. The pasting properties of peak viscosity, setback viscosity and pasting temperature of the composite flour containing pin-milled sorghum flour were higher than those of ultra fine pulverized sorghum flour. The volumes of sorghum bread were lower than that of wheat bread; moreover, they gradually decreased with increasing amounts of sorghum flour, which has inferior dough properties and therefore collapses in the oven. The use of vital gluten (12% based on sorghum flour weight) and emulsifier (SSL; sodium stearoyl lactylate) increased the extensibility and resistance to the extension of the dough, thereby improving its rheological properties. Thus, the oven spring of bread containing sorghum was improved, demonstrating as loaf volume increase up to 15%. However, in the case of breads containing 30% sorghum flour, the loaf volumes were still unacceptably low. Therefore, the formula and the bread making process were further modified as follows: An increase of vital gluten ($12%{\rightarrow}18%$) and shortening ($3%{\rightarrow}6%$), a decrease of mixing time and dough fermentation temperature, and the addition of sorghum flour after gluten development during mixing. The above modifications resulted in the improvement of sorghum bread quality. Therefore, we suggest that pin-milled sorghum flour is more appropriate than ultra fine pulverized sorghum flour for making bread.

Purpose: This study investigated the quality characteristics of Jeungpyun prepared with brown rice and sea tangle powder. Methods: The pH, volume, and spreadability of the dough and moisture content, color, texture and sensory evaluation of the Jeungpyun were performed. Results: The results showed that the pH of the dough decreased in all sample groups with the lapse of fermentation time, and ultimately revealed a pH ranging from 4.55-4.65. The spreadability of the dough significantly decreased as the substitute amount of the brown rice flour increased; the sample group with 1% sea tangle powder showed a significantly larger spreadability than the sample group with 2% sea tangle powder (p<0.05). The moisture content in the Jeungpyun showed a significantly lower result as the substitute amount of brown rice flour increased (p<0.05). Lightness (L) was reduced as the substitute amount of brown rice flour increased, and redness (a) and yellowness (b) also appeared to increase. As a result of measuring the texture, the 50% sample group with a high substitute rate of brown rice flour was observed to have high characteristics of hardness, gumminess and chewiness, and was low in cohesiveness. The result of the acceptance test showed that the sample group that substituted 25% brown rice flour and added 1% sea tangle powder was evaluated to have a significantly higher acceptance than the sample group that added 2% sea tangle powder in terms of color, texture and overall acceptance. Conclusion: The result of the acceptance test showed that the sample group that substituted 25% of brown rice flour and added 1% of sea tangle powder showed higher tendency in all acceptance attributes than the sample group that did not substitute the brown rice flour to show the possibility of developing the Jeungpyun with brown rice.

The quality properties of bread with Lentinula edodes powder were investigated to find the most adequate ratio of the Lentinula edodes powder. The protein and crude fat were increased in proportion to the added quantity of Lentinula edodes powder. The amount of ash was found the most in the bread with 1% Lentinula edodes powder. It was confirmed that the volume of bread with Lentinula edodes powder decreased as the amount of the Lentinula edodes powder increased. The brightness was the highest in the control and was inversely proportional to the added amount of Lentinula edodes powder. The yellowness and redness of the dough were proportional to the added amount of Lentinula edodes powder. Total amino acids and free amino acids were found. The dough with 3% Lentinula edodes powder contained the highest amounts of both, followed by 2%, and 1%. When evaluating the length of storage, the bread's springiness and cohesiveness decreased. Regarding the taste, preference was given to the bread with 2% Lentinula edodes powder, which had the lowest value of bad odors and odd texture in the sensory test.

To establish the optimum formular for processing bread with steam-dried Hizikia fusiformis flour(SHF), it was incorporated into wheat flour by the ratio of 0, 1, 3, 5 and 7% based on a flour weight. Evaluation was performed on the rheological and sensory profile of bread, such as specific loaf volume, water holding capacity(WHC) and height, appearance and Hunter's color value, mechanical texture properties, and sensory value. Increase in the addition of SHF led to the tendency that the expansive force of dough fermentation reduced, and an increase in the textural properties of bread. And cohesiveness, gumminess, and chewiness indicated the tendency of a little reduction as influenced by adding more dried Hizikia fusiformis powder. As for sensory properties and flavor components of the white bread, in case of color and flavor, more than 3% of increase in the addition of the dried Hizikia fusiformis powder led to a drop in preference, and more addition led to a fall in taste and softness. Overall, it was found that adding less than 3% of dried Hizikia fusiformis powder is proper for dough in breadmaking.

The gluten protein content in whole-wheat flour is low, which affects the elasticity and viscosity of the dough. Enzymatic modification of the protein may result in a network that mimics gluten, which plays an important role in the processing of whole-wheat foods. In this study, the effects of Halomonas alkaliantartica laccase (LacHa) on the quality parameters of whole-wheat bread were investigated. The optimum dosage of LacHa was 4 U/100 g of whole-wheat flour. At this dosage, whole-wheat bread exhibited the best specific volume and optimum texture parameters. Laccase also extended the storage duration of whole-wheat bread. We analyzed the micro-structure of the dough to determine its gluten-free protein extractable rate and free sulfhydryl group content, and verify that LacHa mediates cross-linking of gluten-free proteins. The results demonstrated that the cross-linking of gluten-free protein by LacHa improves the texture of whole-wheat bread. As a flour improver, LacHa has great developmental and application potential in baked-food production.
