Effects of Doenjang and Chunggukjang on rheological properties of bread flour were investigated based on falling number, RVA, farinogram, colorimeter, rheofermentometer and SEM. The falling number of bread flour was highest among all samples, and mixed flours containing Chunggukjang showed lower falling number than Doenjang. RVA showed that initial pasting temperatures of the control mixed flour of Doenjang and Chunggukjang increased sequentially, whereas peak viscosities were reversed and final viscosities showed similar results. In the farinogram, consistencies and water absorptions decreased with increasing quantity of Doenjang and Chunggukjang. Developments, stabilities, time to breakdowns and farinogram quality numbers of the mixed flour containing Doenjang were higher than those of Chunggukjang and greater addition decreased values. In the rheofermentometer test, height of maximum dough development of mixed flours containing Chunggukjang were lower than that of flours containing Doenjang. Total volumes, retention volumes and retention coefficients of mixed flours containing Doenjang and Chunggukjang were lower compared to the control. For features, SEM showed that mixed flour containing Chunggukjang showed a faded boundary compared to flour containing Doenjang. All of results showed that the various activities of Chunggukjang were more potent than those of Doenjang.

This study investigated the feasibility of the bread making process with the mixture of the functional rice flour. The bread was manufactured with 20, 30 or 40% functional rice flour with increasing and wheat flour. Gelatinization characteristics of the rice starch was examined by differential scanning calorimetry(DSC). Coated with soluble dietary fiber rice showed the highest gelatinization enthalphy among functional rices and other functional rices were similar to normal rice. in the viscosity point of view. generally the viscosity related to the addition ratio. The most viscose case was 30% Sangwhang rice but in fermented with monascus ruber rice case, viscosity was low even with 40% case because of the transformation of the starch granules. In sensory evaluation, the highest sensory scores for the uniformity of pore size and flavor were obtained when sangwhang rice flour content was 20%. The textual study was mainly focused on the hardness, cohesiveness, adhesiveness, springiness, chewiness. Textural characteristics of functional rice bread crumb bakedwith 20% coated with soluble dietary fiber rice, 20% sangwhang was low in hardness, chewiness and gumminess. Therefore, Sangwhang rice flour 20%, Monascous ruber 20% and Coated soluble dietary fiber rice 20% were considered to be the most suitable addition ratio for the rice breads.

본 연구는 밀가루의 일정량을 당진 특산물인 해나루 쌀가루를 10%, 30%, 50% 대체하여 제조된 식빵의 품질 특성을 알아보고자 진행되었다. 발효율, pH, 부피, 비용적, TPA, 영상분석, 색도, 기호도 검사, 특성차이 검사를 통하여 해나루 쌀가루를 첨가한 식빵을 분석하였다. 발효율은 60분까지는 대조구가 가장 좋았으나, 그 이후부터는 HRF 50 시료를 제외한 나머지 시료 간의 차이는 나타나지 않았으며, 반죽과 식빵 모두 해나루 쌀가루의 첨가량이 높을수록 pH가 높아졌고, 쌀식빵의 부피와 비용적은 감소하였다. TPA와 영상분석 결과, 쌀가루 첨가량이 많을수록 경도와 기공의 조밀도는 증가하였으며, 기공의 찌그러짐은 감소하였고, 색도는 해나루 쌀가루 첨가량에 따라 b값이 낮아졌다. 관능검사 결과 조직감과 풍미, 전체적인 기호도에서 대조구가 가장 좋은 평가를 받았으나, 외관은 HRF 30, 맛은 HRF 10이 대조구보다 더 좋게 평가되었으며, 세 시료 간 유의적인 차이는 발견되지 않아 결과적으로 해나루 쌀가루를 30%까지 첨가하여도 밀가루 식빵과 소비자의 기호도에서 큰 차이는 나타나지 않을 것으로 사료되었다.

Legumes are good sources of various nutrients. Among legumes, soybean and its flour are accessible foods to consumers. However, in case of soybean flour, there is a disadvantage of easily going rancid. Thus, this study aimed to investigate how the quality of soybean flour changes during storage according to the packaging materials and storage temperatures. The raw and roasted soybean flours were packed in two types of packaging, polyethylene (PE) and polypropylene (PP) film bags respectively, and stored at three different storage temperatures (4, 20, and $45^{\circ}C$) for 1 year. The acid value, conjugated diene value, peroxide value, p-anisidine value, thiobarbituric acid (TBA) value, lipoxygenase activity, and fatty acid content of raw and roasted soybean flours were measured at the point of starting storing, and after 1, 2, 4, 8, and 12 weeks of storage. The acid value of soybean flour was increased for 4 weeks and thereafter significantly decreased (p < 0.0001). The conjugated diene value was significantly increased after 4 weeks storage at $45^{\circ}C$ with PE and PP film bags (p < 0.0001). The peroxide value had no changes during 4 weeks storage at $45^{\circ}C$ with PE and PP film bags, and then those was dramatically increased after 8 weeks (p < 0.0001). The p-anisidine values in all of storage conditions were decreased after 4 weeks. Lipoxygenase activity was decreased at 12 weeks storage at $20^{\circ}C$ and $45^{\circ}C$ with PP film bags. Acid value had positive correlations with p-anisidine value (r = 0.30 and p < 0.0001) and lipoxygenase activity (r = 0.36 and p < 0.0001), and had negative correlations with conjugated diene value (r = -0.45 and p < 0.0001) and peroxide value (r = -0.25 and p < 0.001). Conjugated diene value had a high positive correlation with peroxide value (r = 0.76 and p < 0.0001), but that had a negative correlation with lipoxygenase activity (r = -0.51 and p < 0.0001). Peroxide value had negative correlations with p-anisidine value (r = -0.20 and p < 0.01) and TBA value (r = -0.15 and p < 0.05). The degree of reduction in fatty acid content of raw soybean flour was higher than the roasted soybean flour during the storage. Total fatty acid content had positive correlations with acid value (r = 0.45 and p < 0.0001) and p-anisidine value (r = 0.58 and p < 0.0001), but had a weak negative correlation with conjugated diene value (r = -0.19 and p < 0.01). This study showed how the rancidity of the raw and roasted soybean flours progressed during storage. Thus, our findings can be used as base data to do a further study of finding and developing more stable storage conditions of the soybean flour.

본 연구에서는 알러지 반응 저감의 특성을 가지고 있는 오프리 밀가루를 이용하여 적절한 물리적 방법을 통해 제과적성을 개선시키고자 하였다. 오프리 밀가루는 높은 단백질 및 글루텐 함량을 가지고 있어 쿠키를 제조하였을 때 가공적성이 낮은 특징을 가지고 있다. 밀가루에 대한 마이크로웨이브 조사는 글루텐의 형성에 영향을 미친다는 보고에 따라, 본 연구에서는 오프리 밀가루에 마이크로웨이브 조사를 통해 제과 가공적성을 개선하고자 하였다. 그 결과, 마이크로웨이브조사는 오프리 밀가루의 단백질의 함량 및 글루텐 함량에는 영향을 미치지 않았지만 이를 이용하여 쿠키를 만들었을 때 퍼짐성과 균열정도가 개선되는 것을 확인 할 수 있었다. 이는 마이크로웨이브조사가 글루텐 형성에 영향을 미쳐 반죽점도를 감소시켜 쿠키의 가공적성이 개선되는 것을 확인 할 수 있었다. 하지만 과도한 열처리는 단백질의 변성을 유도하여 오히려 가공적성을 감소시켰고, 이에 따라 사용목적에 따른 적절한 처리조건을 규명하는 것이 필요하다. 따라서 이러한 연구결과를 통해 높은 단백질 및 글루텐함량을 가지고 있는 밀가루를 대상으로 적절한 마이크로웨이브와 같은 물리적 처리를 통해 가공적성을 개선하여 활용도를 높일 수 있을 것으로 예상된다.

This investigation was undertaken for the purpose of studying the quality and sensoryptability of Jangduck during storage containing various levels of glutinous rice flour. Composition of experiment Jangduck made with different components and contents. A standard samples of Jangduck were soybean paste : glutinous rice flour : ground beef : green onion : garlic : toasted white sesame=100 : 10 or 20 or 30 : 30 : 10 : 5 : 2 (％) and measured acceptability by 15 days. Jangduck estimated for texture characteristics through acceptability. The acceptability of Jangduck was by both objective and subjective methods. Objective measures were made utilizing the Rheometer and Hunter colorimeter. Sensory evaluated was done by a panel of 10 judges. The data analysis revealed following as for estimate of texture changes during storage by Rheometer, the hardness tended to increase as the addition level of glutinous rice flour and beef till 30 days. Hardness decreased slightly after 30 days of storage. Elasticity and cohesiveness tended to increase as the addition level of glutinous rice flour till 15 days and decreased slightly from 16 days to 60 days later By color value of Jangduck, Lightness tended to increase as the addition level of beef during storage periods. Redness tended to increased as addition level of beef before storage and decreased 15 days later. Yellowness increasde than others from days later to 15 days later as the addition level of glutinous rice flour. The result of sensory evaluation revealed that Cl [soybean paste : glutinous rice flour : ground beef : green onion : garlic : toasted white sesame=100 : 30 : 30 : 10 : 5 : 2(％)] produced the best quality in most sensory characteristics during storage.
