  • White salted noodles and pan bread were prepared from Korean wheats with 1Dx2.2+1Dy12 subunits in high molecular weight glutenin subunits (HMW-GS) to evaluate the suitability for end-use products through the comparison with US wheats with various classes and commercial wheat flours. Korean wheat flours with 1Dx2.2+1Dy12 subunits showed higher SDS sedimentation volume than US wheat flours with similar protein content. Compared to wheat flours with similar protein content and SDS sedimentation volume, water absorption percent of Korean wheat flours using a mixograph was higher than that of US wheat flours, but similar to commercial wheat flours. Mixograph mixing time was similar to hard wheat flours and commercial noodle flours. Optimum water absorption percent of noodle dough from Korean wheat flours was higher than that of US wheat flours. Noodle sheets from Korean wheat flours with 1Dx2.2+ 1Dy12 subunits showed lower L values, higher a values and similar b values compared to commercial noodle flours. Hardness of cooked noodles from Korean wheat flours 1Dx2.2+1Dy12 subunits correlated positively with protein content, NIRS hardness, mixograph water absorption and gluten yield of flours. Korean wheat flours with 1Dx2.2+1Dy12 subunits showed lower loaf volume and harder crumb firmness than hard wheat flours and commercial bread wheat flours in spite of similar protein quantity and quality to hard wheat flours.

  • 한국산 triticale과 연질 밀을 사용하여 그들의 이화학적 특성, 제분 특성 및 제품 특성을 조사하였던 바 그 결과를 요약하면 다음과 같다. 1. Triticale은 단백질 함량이 높고 아미노산 조성도 밀 보다 양호하였으나 제한 아미노산은 역시 lysine이었다. 2. Triticale 의 식품 이용상의 문제점은 밀가루 수율이 떨어진다는 점과 $\alpha-amylase$ 역가가 높다는 점이었다. 3. 밀가루 수율이 밀보다 약 10% 정도 낮았으며 제빵으로 이용하는 경우 빵의 용적이 밀 보다 떨어졌다. 4. 그러나 triticale도 국수 제조에는 큰 문제가 없었으며 $M_{1}A$ 품종의 경우 특히 국수 적성이 양호하였다.

  • Protein characteristics of Korean wheat were evaluated to determine the effects of protein content and quality on processing and textural properties of white salted noodles compared to US wheat flours with various wheat classes and commercial flours for making noodles. Protein quality parameters, which were independent of protein content and included SDS sedimentation volume with constant protein weight, mixograph mixing time and proportion of 50% 1-propanol insoluble protein, of Korean wheat flours with 2.2+12 subunits in high molecular weight glutenin subunit compositions were comparable to those of commercial flours for making noodles. Parameters related to noodle making, including optimum water absorption, thickness and color of noodle dough sheet, correlated with protein content and related parameters, including SDS sedimentation volume with constant flour weight, mixograph water absorption and gluten yield. No significant relationship was found in protein parameters independent of protein content. Hardness of cooked noodles from Korean wheats was lower than that of US wheat flours compared to similar protein content of commercial noodle flours. Adhesiveness, springiness and cohesiveness of cooked noodles from Korean wheats were similar to US wheat flours. Hardness of cooked noodles correlated with protein content and related parameters.

  • The effect of using Korean wheat flour versus Australian wheat flour on noodle quality as a result of differing physical and chemical properties of the flours was investigated. The results provided appropriate technical information for selection of wheat varieties to produce high quality Korean salted noodles. Noodle quality was quantified based on measurement of the appearance and texture of noodles. When consumer preference tests were conducted, a firmer and more elastic texture was preferred for Korean white salted noodles, however, when appearance was included in the consumer tests, noodles made with Australian wheat were favored over Korean wheats. Korean flour was found to produce firmer and more elastic noodles, whereas Australian flour produced brighter, creamier colored noodles. In flour quality tests, Korean flours were found to have a higher setback viscosity and lower swelling power than Australian flour. Additionally, Korean flours had higher water absorption values. Protein content of flour was an important parameter affecting the firmness of Korean noodles, whereas setback viscosity and swelling power were the major determinants of elasticity. Overall, the important parameters for determination of the quality of Korean salted noodles were high setback viscosity, low swelling power, and high protein content.

  • A study was conducted on the preparation of Ramyon using composite flours of raked barley (20 or 30%)-wheat(80 or 70%) in commercial plant scale and on the quality evaluation of Ramyon made from those flours. The naked barley(20%)-wheat(80%) flour gave acceptable Ramyon-making characteristics during the continuous Ramyon manufacturing process. The composite flours had a higher water absorption rate in kneading process and oil absorption value of the Ramyon product than those of wheat flour alone. Even though the Ramyon of composite flours showed a little inferior value compared with wheat flour alone in the cooking and texture characteristics, sensory panel scores of Ramyon indicated that the naked barley (20%)-wheat(80%) flour was acceptable in Ramyon.

  • 국내산 밀품종인 그루밀과 탑동밀의 성분분석과 수입밀과 전분의 대체 비율 또는 가수량을 달리 하였을 때의 반죽 및 국수의 품질특성을 살펴보았다. 국내산 밀가루는 수입 연질밀에 비해 단백질과 회분함량이 높았다. 국내산 밀가루반죽은 수입밀보다 수분흡수율과 반죽도달시간이 높게 나타났으며, 안정도는 낮고 약화도가 높게 나타났다. 탑동밀의 반죽형성시간이 가장 높았으며, 그루밀이 가장 짧게 나타남으로써 연질밀일수록 반죽형성시간이 짧게 나타남을 알 수 있었다. 탑동과 그루밀에 수입밀 혼합량이 증가함에 따라 수분 흡수율은 감소되는 경향을 보였으며, 반죽형성시간은 탑동밀에 수입밀 30% 대체까지는 감소하였다. 수입 산 밀가루의 첨가는 국내산 탑동과 그루밀의 연화를 감소시켰으며, 가수량이 증가함에 따라 전 시료의 점착성이 증가하였는데, 특히 그루밀의 가수량 65%, 10~20% 수입밀 혼합시 가장 점착성이 높게 나타났다 견고성은 가수량이 증가할수록 감소하였고, 품종별로는 탑동밀이 수입산 밀가루에 비하여 높은 견고성 을 보였다. 국수의 기계적인 조직감은 탑동밀에 수입 밀의 첨가는 인장력은 증가하고 인장길이는 감소되었으며, 그루밀은 이와는 반대의 경향이 나타났다. 국수의 견고성은 대조구(수입산 밀가루)>탑동>그루밀 순서였으나, 수입산 전분 첨 가량이 증가함에 따라 품종에 관계없이 견고성, 부착성및 씹힘성 모두 증가하였고, 3%이상 첨가시 대조구와 거의 비슷한 경도를 나타내었다. 전분의 첨가에 따른 조리된 국수가닥의 인장력은 대조구인 수입산 밀가루에 비하여 탑동과 그루밀에서 비교적 낮은 값을 보였고, 인장길이는 대조구에비하여 전반적으로 늘어나지 않아 국내산 밀이 대조구보다 쉽게 끊어지고 늘어나지도 않음을 알 수 있었다 따라서 그루와 같은 한국산 연질밀은 아밀로즈 함량이 높거나 단백 질함량이 상대적으로 낮은 밀가루를 혼용한다면 수입밀에 뒤지지 않는 제면 성질을 가지며 유연성을 더욱 향상시킬 수 있음을 알 수 있었다.

  • This study was carried out to investigate the quality of bread made with different types of brown rice flours. 20% of the wheat flour from the bread recipe was substituted with the different types of brown rice flours, such as, raw brown rice flour (RBRF), soaked brown rice flour (SOBRF), and sprouted brown rice flour (SPBRF). The loaf volume of the bread: decreased by 3.2%∼7.4% with the addition of the brown rice flours. The "L" value of these breads decreased, while the "a" and "b" values increased. In terms of the texture, the SPBRF bread was the hardest on the 1st day of storage, but it was the least hard on the 5th day of storage. The RBRF bread was the least springy. The SPBRF bread was the most cohesive. The adhesiveness was not significantly different among the breads. In terms of the degree of retrogradation using the ${\alpha}$-amylase method, the SOBRF and SPBRF breads showed a little lesser degree of retrogradation than the control and the RBRF bread. In the sensory evaluation, the control bread obtained high score for crumb color and grain, while the brown rice flours breads obtained high scores for mouthfeel and taste. Overall acceptability, defined by a higher score, was higher for the SOBRF and SPBRF breads than the control bread, which was not significant. Thus, this study showed that processing rice flour was more effective than raw rice flour in substituting wheat flour.

  • Effects of transglutaminase (TG) on physicochemical properties of dough prepared with 20% resistant starch (RS)-added wheat flour were investigated. RS levels of wheat flours added with native wheat starch (NS), Hi-maize (RS2), retrograded (RS3), and cross-linked (RS4) wheat starches were 2.97, 11.88, 5.79, and 9.09%, respectively. Peak viscosity of NS-added flour was higher, whereas setback was lower, than those added with other resistant starches. TG had no effect on pasting behaviors of RS-added flours. Water absorption ranged from 66.5 to 79.0%, and development time increased with RS addition. TG increased tensile strength of dough after fermentation and bread volume, due to well-developed gluten network resulting from cross-linking facilitated by TG Addition of TG decreased hardness of baguettes, with RS2-added baguette showing lowest value. These results indicate addition of TG enhanced eating quality of RS-added breads.

  • The principal objective of this study was to evaluate the effects of the addition of sourdough to various grain flours in bread, specifically, in regards to the physicochemical characteristics of bread dough, sensory evaluation, and bread storage. As the incubation time of sourdough increased, the total titratable acidity increased. Viable yeast counts of sourdough increased consistently until the third day, while lactic acid bacteria counts increased until the second day. The weight of breads containing sourdough made with rye flour, strong flour, and Korean wheat flour were higher than that of the control. However, the height, volume, and specific volume of control were higher than those of the groups with sourdough made with various grain flours. The pH of breads containing sourdough was lower than that of the control, while the total titratable acidity and moisture content were higher than those of the control. In analyzing the visible mold colony during the five days of storage at $30^{\circ}C$, mold growth in breads containing sourdough made of Korean wheat flour, barely flour, and rye flour was retarded. In the color measurement, the L values of the control and bread containing sourdough made with barley flour were higher than that of the other groups after five days. The a value of bread containing sourdough made of rye flour was higher, and the b values of breads containing sourdough made of Korean wheat flour, barley flour and rye flour were higher than those of the other groups after five days. The hardness of breads containing sourdough increased as storage time increased, where as breads containing sourdough made of Korean wheat flour, Korean whole wheat flour, and rye flour revealed no significant differences with control group. Sensory evaluation scores in terms of after swallowing, taste, and overall preference of bread containing sourdough made of Korean wheat flour was higher than those of the control group.
