The purpose of this study was to evaluate the quality characteristics of white pan bread added with wheat sprout powder without treatment (WP) and wheat sprout powder with only enzyme treatment (WPE), only lactic acid bacteria treatment (WPL) and enzyme and lactic acid bacteria treatment (WPE&L). The three different powder concentration levels of 1%, 3%, and 5% were added to flour to produce the white pan bread. The bread volume and specific volume of the WPE&L group were the highest among all the addition groups. The bread weight, a-value, and b-value of the WP group was highest among all the addition groups, but the bread baking loss and the L-value of the WP group was the lowest among all the addition groups. The texture measurements indicated that the hardness, gumminess, and chewiness values of the bread were the highest in the WP group. The sensory evaluation test showed that bread in the WPE&L group with 3% wheat sprout powder was the best among all the samples studied. Based on our findings, we suggest that the enzyme and lactic acid bacteria pretreated wheat sprout powder is an effective ingredient for improving the overall quality of white pan bread.

Five-color bread was prepared by adding herb powder to Korean whole wheat triticum aestivum flour and the quality of baking was analyzed. The pH of the control bread was 6.15±0.12 while that of the whole wheat flour test group was 6.35±0.11, 6.29±0.12, 6.36±0.12, 6.19±0.11, and 6.01±0.13, respectively. The L value of the control bread was 67.78±0.03 and that of the whole wheat flour test group was 69.66±0.02, 60.01±0.12, 64.23±0.01, 63.34±0.01, and 61.64±0.04, respectively. The water activity was slightly increased at 2 days of storage due to the difference in water absorption and water retention. However, on the third day, the water transfer phenomenon in the bread showed water activity decrease in all wheat flour test groups. On the 1st day of the whole wheat flour test bread, the hardness values were 186.86±4.81, 165.89±3.73, 189.71±3.32, 198.38±2.19, and 184.29±3.40 g/cm2, respectively, and that of the control group was 138.84±3.72 g/cm2. The hardness of the control group and the whole wheat flour test group showed a significant difference. The internal structure of the bread in the whole wheat flour test group (100x, 500x) was not smoother than the control’s. The swelling degree of the starch particles and the cracking of the crumbs were confirmed by the adding of five-colored herbs to whole wheat flour.

In the Anzunbaengi (Triticum aestivum) whole wheat flour mixture group, some herbs (A [white], B [yellow], C [black], D [blue], and E [red]) were added. The physicochemical properties were compared to the strong flour and whole wheat flour mixture groups. The dry gluten content of the control group (strong flour) was 13.5±0.4%, and the content in the whole wheat flour test group was slightly lower in value than the control group. The final viscosity, breakdown, and setback values of the dough were 248.4±0.8, 104.8±0.9, and 103.1±2.9 RVU, respectively. The breakdown was significantly different in the control and whole wheat flour groups. The setback value of the dough was increased by 30 RVU in the whole wheat flour test group compared to the control group by 103.1±2.9 RVU, but there was no significant difference between the test group samples. The consistency of the control dough was 500±10 FU, and the whole wheat flour test group was significantly increased to 585±10~599±10 FU, respectively. The absorption rate was about 2% higher in the whole flour test group than in the control group (66.2±0.3%). The pH of the control paste gradually decreased with fermentation time, and the results of whole wheat flour test group were similar (5.78±0.12~5.88±0.12). As the fermentation time increased, the volume of dough was increased and the result was slightly lower in the whole wheat flour test group than in the control group.

The objective of this study was to compare physicochemical, microbial, and antioxidant properties of domestic and imported wheat kernels for bread making. Two domestic (JK1, 2) and three imported (ND, DNS, and CWRS) kernels were compared. Domestic kernels had higher moisture contents, and lower ash and protein contents (p<0.05). In grain characteristics, JK1 had 13.62% of damaged kernels, which was the highest among the samples (p<0.05). JK2 was similar to imported kernels in the ratio of sound kernels, foreign materials, and damaged kernels. Kernel size of JK1, 2 was larger than the imported kernels; therefore, kernels area and perimeter were higher by the image analyzer. Domestic kernels hid lower total aerobic counts the imported kernels (p<0.05). Domestic kernels and DNS had no yeast, while NS and CWRS had yeast in kernels. DNS (3.08 mg gallic acid equivalent (GAE)/g) had the highest total polyphenol content (TPC), followed by JK1 (2.81 mg GAE/g). JK2 had the lowest amount of TPC as 2.26 mg GAE/g. Total flavonoid content (TFC) was the highest in DNS as 0.44 mg catechin equivalent (CE)/g and JK2 was the lowest as 0.12 mg CE/g. Domestic wheat kernels had lower protein content and lightness than the imported wheat kernels so that flour from domestic wheat kernels may have lower quality for baking.

This study was performed to produce WBM (wheat and barley mixture) bread containing molokhia powder with quality characteristics and antioxidant activities. Analysis of the chromaticity of WBM prepared with molokhia powder showed that; the lightness and redness were decreased, but yellowness was increased. In mechanical properties, hardness, gumminess, and chewiness were significantly increased as the amount of molokhia powder was increased. However, cohesiveness was significantly decreased. In sensory evaluation, WBM bread containing 1.5% of molokhia powder (MB1.5) showed an overall high preference level. The total polyphenol content of molokhia powder EtOH extract and MB1.5 were 29.19 and 58.18 mg TAE/g, respectively. The total flavonoid contents of molokhia powder EtOH extract and MB1.5 were 20.62 mg and 33.25 mg RE/g, respectively. The radical scavenging ability (IC50) of DPPH (IC50) for molokhia powder EtOH extract and MB1.5 was 31.04 and 58.18 μg/mL, respectively while that of ABTS was 33.25 and 54.15 μg/mL, respectively. The α -glucosidase inhibitory effects of molokhia powder EtOH extract and MB1.5 were 494.88 and 814.88 μg/mL, respectively. MB bread containing 1.5% molokhia powder showed antioxidative effects and α-glucosidase inhibitory activity, meaning that not only molokhia but also MB1.5 bread has the potential to prevent chronic degenerative diseases such as diabetes.

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.

Rice flour is used in many food products. However, dough made from rice lacks extensibility and elasticity, whereas that of wheat is suitable for many food products including breads. We have produced marker-free transgenic rice plants containing a wheat TaGlu-Ax1 gene encoding the HMG-GS from the Korean wheat cultivar ‘Jokyeong’ using the Agrobacteriummediated co-transformation method. The TaGlu-Bx7-own promoter was inserted into a binary vector for seed-specific expression of the TaGlu-Ax1 gene. Two expression cassettes comprised of separate DNA fragments containing only TaGlu-Ax1 and hygromycin phosphotransferase II (HPTII) resistance genes were introduced separately to the Agrobacterium tumefaciens EHA105 strain for co-infection. Each EHA105 strain harboring TaGlu-Ax1 or HPTII was infected to rice calli at a 3:1 ratio of TaGlu-Ax1 and HPTII, respectively. Then, among 210 hygromycin-resistant T0 plants, we obtained 20 transgenic lines with both TaGlu-Ax1 and HPTII genes inserted into the rice genome. We reconfirmed integration of the TaGlu-Ax1 gene into the rice genome by Southern blot analysis. Transcripts and proteins of the wheat TaGlu-Ax1 were stably expressed in the rice T1 seeds. Finally, the marker-free plants harboring only the TaGlu-Ax1 gene were successfully screened at the T1 generation.

Whole grain wheat bread and bakery products is highly considered as a functional food due to the high amount of vitamins, minerals, and dietary fiber in whole wheat flour. However, as the lower end-use properties of whole wheat products limit consumer selection, it is required to measure the functionality of whole wheat flour. Thus, it is observed the fermentation properties of bread dough from the composite flour of whole grain and white wheat flour. Whole grain cv. Chokyeong developed in the NICS was ground using a hammer mill with 0.5 mm sieve. The composite flour was prepared by substituting wheat flour with whole grain flour at 15, 30, 45% levels. Breads were prepared using the 100 g composite flour according to a basic straight-dough mehtod (AACC 10-10A) with slight modification. A rheofermentometer was used to measure the maximum dough height (Hm) and the maximum gas formation (H’m) during fermentation. Also, total CO2 production was recorded. The Hm decreased from 38.8 to 27.5 (mm) with increasing whole wheat flour from 15 to 45%. Whereas, the H’m was increased from 61.7 to 60.8 (mm) with whole wheat flour increment. Total CO2 production was also decreased with increasing whole wheat flour ranging 1312∼1164 (ml). The fermentation results could be useful to partly predict the effect of substituting whole wheat flour on the end-use quality of pan-breads.

“Joongmo2008”, a winter wheat (Triticum aestivum L.) cultivar was developed by the National Institute of Crop Science, RDA. It is an awned, semi-dwarf and hard winter wheat. The heading and maturing date of “Joongmo2008” were similar to “Keumkang”. Culm and spike length of “Joongmo2008” were 87 cm and 8.6 cm. It had similar test weight (800g/L) and higher 1,000-grain weight (46.7g) than “Keumkang”. It showed resistance to winter hardiness and moderate to pre-harvest sprouting, which lower rate of pre-harvest sprouting (9.8%) than “Keumkang”. “Joongmo2008” had higher flour yield (73.5%) and higher ash content (0.49%) than “Keumkang”. It showed similar lightness (90.01) of flour color than “Keumkang”. It showed higher protein content (16.4%), gluten content (13.4%), SDS-sedimentation volume(59㎖) and mixing time of mixograph than “Keumkang”. “Joongmo2008” had lower amylose contetn (24.5%) and higher viscosity (153BU) than “Keumkang”. It showed same compositions in HMW-GS compositions(5+10) and Puroindolines composition compared to “Keumkang”. “Joongmo2008” showed lower firmness (0.74N) of and higher bread volume of baked pan-bread to “Keumkang”. Average yield of “Joongmo2008” in the regional adaptation yield trial was 4.54 ton/ha in upland and 3.67 ton/ha in paddy field. “Joongmo2008” would be suitable for the area above -10℃ of daily minimum temperature in January in Korean peninsula.

This study was conducted to compare the protein characteristics, dough rheology and bread loaf volume of Korean wheat cultivars and CIMMYT lines produced in diverse environments and to determine the genetic and environmental effects on bread making quality. Protein characteristics, including protein content and SDS-sedimentation volume, mixing properties during dough development and bread loaf volume were primarily influenced by the environment. Wheat cultivated in Jinju exhibited higher SDS-sedimentation volume based on constant protein weight and bread loaf volume than those in Suwon and Iksan. SDS-sedimentation volume based on constant protein weight, mixing time of mixograph and mixing tolerance of mixograph were positively correlated with bread volume. Korean wheat cultivars showed different allelic variations of Glu-1 and Glu-3 compared to CIMMYT wheat lines. Alchanmil, Keumkangmil and Tapdongmil could be suitable for bread making because these cultivars exhibited a 10 point Glu-1 score. However, Korean wheat cultivars should be introduced specific alleles in Glu-3 loci, including Glu-A3b or d and Glu-B3b , d , f or g , to improve gluten strength related to increase bread loaf volume.

Barley is a good source of dietary fiber, β-glucan, which confer a number of human health benefits. The properties of a white wheat bread could be changed by adding regular and waxy barley flour in small amounts to a white wheat bread recipe. The objectives were to replace wheat flour with different levels of regular and waxy barley flour, and to examine their effects on bread qualities. Barley grains, Sassal(SS) as regular andSachalssal(SCS) as waxy cultivars, were ground usinga hammer mill equipped with 0.8 mm screen. A commercial bread wheat flour (WF) was used as a base flour. The blends with three levels (10, 20, 30%) of barley flour substitution were prepared, and the baking process was followed by the AACC official 10-10A. When barley flour substitution increased, beta-glucan was significantly increased: the highest beta-glucan in the waxy barley flour blends (0.1% in WF, 1.91% in 30% SCS). While WF bread had the highest loaf volume, substituting 20% SS did not statistically (p<0.05) affect the loaf volume, however a significantly lower loaf volume at 30% barley flour. On the other hand, the loaf volume of SCS breads lowered significantly by substitution statistically. The hardness and chewiness increased by replacing barley flour from 10 to 30% progressively: a remarkable increase in adhesiveness at 30% SCS bread. From the results, substitution of 10% barley flour regardless of regular and waxy did not affect bread volume and firmness, being suitable to use 20% SS barley flour without a significant change in loaf volume. From the nutritional point of view, substituting barley flour up to 20% would be an effective way to increase the dietary fiber on white wheat based breads.

“Jokyoung”, a new bread making wheat cultivar, was developed from the cross between “Seri 82”, a hard white wheat from CIMMYT, Mexico and “Keumkang”, a hard white wheat with high milling rate and early maturing from Korea by National Institute of Crop Sci

Bread baking parameters and relationships between bread baking properties and flour characteristics were evaluated for two years, 1997 and 1998, and at two locations, Suwon and Deokso, with Korean winter wheat cultivars and lines. Among the bread baking parameters, lightness of crumb grain showed differences between years. No significant differences were found in dough mixing time, bread loaf volume, crumb grain score or firmness. Keumkangmil, Suwon 278 and Tapdongmil showed higher bread loaf volume, good structure of crumb grain and softer crumb firmness. However, compared to commercial flours for baking, cultivar means averaged over years and locations of nineteen Korean winter wheats showed poor bread baking quality because of low protein content and unsuitable protein quality. Protein content and flour swelling volume showed better relationships with the bread baking parameters than other flour characteristics. Friabilin-absence lines showed softer crumb firmness than those of friabilin-presence lines
