We evaluated chemical, sensory and mechanical properties of breads containing different amount of Paecilomyces japonica powder to provide the basic informations for the development of functional bread. The pH of dough with 2% Paecilomices japonica powder was the highest but the pH of dough with 3% Paecilomices japonica powder was the lowest. Baking loss rate of bread added 3% Paecilomices japonica powder was the lowest but that of bread added 1% Paecilomyces japonica powder was the highest in that. The result of sensory evaluation showed that bread added 1% Paecilomices japonica Powder was significantly more preferable in chewiness, mouth feel, texture quality and overall quality. Sensory properties of softness, wheat flour odor, moisture, and mouth feel were positively correlated with the acceptability. Mechanical properties of hardness and chewiness had negative correlation with sensory properties, but springiness, gumminess and brittleness had positive correlation with those. The results of various measurements and evaluations showed that the quality of bread containing the Paecilomices japonica powder could be well accepted organoleptically. And this in turn proves the possibility of functional bread by use of Paecilomices japonica.

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.

To develop functional bread and improve the quality of gluten-free bread, this study investigates the quality characteristics of gluten-free rice bread made from soft-type rice (Bodeurami) flour mixed with black rice at different levels (0%, 10%, 20%, 30%, and 40%, w/w). An increase in the mix level of black-rice flour increased the weight of rice bread but reduced its volume, baking loss, volume expansion, and specific volume. The results for Hunter's color value and texture measurements indicate that an increase in the content of black-rice flour reduced the L-value, the b-value, hardness, gumminess, and chewiness but increased the a-value, adhesiveness, and springiness. According to the sensory analysis, rice bread formulated with a mixture of soft-type rice flour (80%) and black-rice flour (20%) showed the highest scores in color, taste, texture, and overall preferences. With respect to flavor and appearance, bread samples with 20% and 30% black-rice flour were preferred to those with 0%, 10%, and 40% black-rice flour. These results suggest that gluten-free rice bread mixed with wet-milling rice flour and black-rice flour can be used to develop functional and gluten-free bread.

다시마를 Vibrio sp.로 분해하여 제조한 SCD로 기능성 빵을 만들기 위하여 mixture design을 이용한 원료의 최적 배합 비율을 구하였다. 다시마 SCD 빵의 max weight, strength, hardness 및 비용적의 값은 밀가루와 물의 첨가량이 증가할수록 감소하는 반면, SCD의 첨가량이 증가할수록 증가하였다. 밀가루와 물의 첨가량이 증가할수록 SCD의 첨가량이 감소할수록 발효팽창력의 값은 증가하였다. 밀가루의 첨가량이 증가할수록 SCD의 첨가량이 감소할수록 SCD 빵의 L(명도) 값과 b(황색도) 값은 증가하였으며, 밀가루와 물의 첨가량이 증가할수록 SCD의 첨가량이 감소할수록 다시마 SCD 빵의 a(적색도) 값은 감소하였다. ANOVA 분석에 의한 다시마 SCD 빵의 max weight, strength, hardness, 비용적, 색도 b(황색도) 값 및 수분흡착력은 linear model이 결정되었으며, distance, 발효팽창력, 색도 L(명도) 및 a(적색도) 값은 nonlinear model(quadratic model)이 선정되었다. Constraint coefficient 값의 분석 결과 SCD는 SCD 빵의 texture에 가장 큰 영향을 주었으며, 물은 발효팽창력, 비용적 및 수분흡착력에 가장 큰 영향을 미쳤다. 또한 밀가루는 SCD 빵의 색도에 가장 큰 영향을 미쳤다. Distance에서는 flour-SCD 및 water-SCD 상호작용이 있었으며, 발효팽창력에서는 flour-SCD 상호작용이 있었다. 또한 SCD 빵 색도의 L(명도)에서는 flour-SCD의 상호작용이 나타났으며, a (적색도)에서는 flour-SCD 및 water-SCD 상호작용이 있었다. Mixture(modified distance) design에 의해 결정된 다시마 SCD 빵의 밀가루, 물 및 SCD의 최적 배합비율은 각각 48.25, 30.89 및 3.86%이었다. 관능검사 결과 전해수로 처리한 SCD 빵은 시중제품보다 모든 면에서 품질이 낮았으나, 전해수 처리 SCD 빵은 대조구(전해수 미처리)보다 월등히 높은 점수를 받아 전해수로 처리된 SCD 빵의 맛, 조직감 및 향을 개선한다면 SCD의 산업화가 가능할거라 판단된다.

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.

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.

To enhance the nutritional quality of the Soboru bread, a dietary fibers extracted from Kombu was added into wheat flour in the amounts of 0, 1, 3, and 5% and the quality of the baked products was characterized. The inherent water holding capacity of the added dietary fibers raised weight of the bread while specific volume and density values were decreased at the same time. Increasing the amount of dietary fiber resulted in the decreased setback time of the raw materials in amylogram. The lower textural hardness of the dietary fiber-enriched bread after one-day storage at room temperature could be attributed to the retarded retrogradation of the starch. Darkened surface of the bread as indicated by the Hunter colorimetric values and the accompanied change in flavor did not significantly influence the sensory evaluation of the products. Judging from texture, taste and overall acceptability of the product, recommended substitution level for the dietary fiber in Soboru bread was 3% or less. Increased intake of the dietary fibers, accompained with more use of seaweed, was expected through the suggested functional bread.
