본 연구를 통하여 조생 다수성 벼 품종인 남일벼의 돌연변이 후대계통으로 'Namil(SA)2652-RGA-l-l-l-l'의 계보를 지니며 Namil(SA)-flo1로 명명된 분질계통의 건식제분 적성과 쌀가루의 이화학적 특성과 호화특성 등을 평가하였다. 배유절단면의 전자현미경 관찰결과 원품종인 남일벼는 배유절단면이 부드러우며 다변각의 전분립들이 치밀하게 배열된 반면 Namil(SA)-flo1은 원형모양의 전분립들이 매우 성기게 배열되어있었다. Namil(SA)-flo1의 작물학적 특성은 남일벼와 유사하였으나 등숙비율과 천립중이 낮았으며 이러한 특성은 백미수량 감소로 이어짐을 알 수 있었다. 조직분석기들 이용한 곡립경도측정 결과 Namil(SA)-flo1는 3,417 g으로 남일벼 (7,526 g)의 45% 수준으로 매우 낮았다. 건식제분기인 Buhler 제분기를 이용해 동일조건에서 생산된 쌀가루들에 대한 입도분석결과 Namil(SA)-flo1는 평균 86.1um 로서 원품종인 남일벼 (109.1um )는 물론 화성벼(112.2um )나 설갱벼 (97.6um )보다 매우 고운입자로 이루어져 있음을 확인하였다. 건식제분에 의한 쌀가루의 손상전분량 역시 Namil(SA)-flo1가 5.1% 수준으로 남일벼 (9.2%), 화성벼(10.3%) 및 설갱벼(7.1%) 보다 매우 낮아 Namil(SA)-flo1의 높은 건식제분 적합성을 확인할 수 있었다. 반면 Namil(SA)-flol에서 생산된 쌀가루의 이화학적 특성과 호화특성은 원품종인 남일벼의 고유한 특성을 견지하고 있는 것으로 사료되었다.

카페인 함량이 커피분말보다 훨씬 낮으면서 거의 재활용하지 않고 있는 커피추출 잔여물을 식품재료로 재활용하기 위한 일환으로, 이것을 1%, 3%, 5%순으로 첨가량을 달리하여 쿠키를 제조하여 그 품질특성을 조사하였다. 그 결과 쿠키반죽의 pH는 대조구보다 커피추출 잔여물의 첨가구에서 유의적으로 낮아지는 경향을 보였다. 또한 반죽의 수분 결합 능력은 3% 첨가구에서 18.81로 가장 높게 측정되었고 반죽의 아밀로그래프 측정결과 중 호화개시 온도는 첨

특수미 품종인 고아미2호는 취반용 쌀로는 적합하지 않으므로 가공용 기능성 곡류소재로서의 활용성을 알아보고자 제빵 시 강력분의 일부를 쌀가루로 대체하였으며 일반 쌀 품종인 추청벼 쌀가루와의 제빵특성을 비교하였다. 쌀가루의 호화특성은 고아미2호는 전분 호화 시 호화개시온도가 높고 전분 팽윤 현상이 억제되어 호화 점도가 매우 낮았다. 강력분에 쌀가루를 10~30% 대체한 혼합분의 mixograph특성은 고아미2호 복합분은 쌀가루 함량이 증가 할수록 가

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.

Allelic variations in glutenin and puroindolines of Korean wheat cultivars evaluated to determine the effects of allelic variations on physico-chemical properties of flour and qualities of white salted noodles. In grain hardness and flour yield, Pinb-D1b had higher hardness index and flour yield than Pinb-D1a alleles. Glu-B1b and Glu-D1f also had lower hardness index than other alleles at the same locus and Glu-A1c, Glu-A3e and Glu-B3i alleles showed lower flour yield than other alleles. In flour compositions, Pina-D1b and Pinb-D1b showed higher particle size, ash and damaged starch content and lower lightness of wheat flour than Pina-D1a and Pinb-D1a. Glu-A1c, Glu-B1b, Glu-D1f, Glu-B3d and Glu-B3i showed lower particle size of flour than other alleles at Glu-1 and Glu-B3 locus. Korean wheats with Glu-B1f, Glu-D1a and Glu-B3b alleles had higher damaged starch content and lower lightness of flour than wheats other alleles at the same locus. Glu-B1b, Glu-D1f, Glu-B3d and Pina-D1a showed lower protein content and Glu-A1c, Glu-B1b, Glu-D1f Glu-B3d, Glu-B3i and Pinb-D1b showed lower SDS-sedimentation volume than other alleles. Hardness of cooked noodles ranked as Glu-A1a > Glu-A1c > Glu-A1c at Glu-A1 locus. Glu-B3h showed higher hardness of cooked noodles (5.10 N) than other alleles at Glu-B3 locus (< 4.66 N).

Flour characteristics of 26 Korean wheat cultivars(KWC) were evaluated to assess consumer satisfaction with 6 imported wheat and 5 commercial wheat flours. In physical characteristics of flours, Particle size of SW(soft white) was similar to Dahong, Geuru, Milsung, Olgeuru, Seodun, Tapdong, and Uri. DNS(dark northern spring) was similar to Jeokjoong, Joeun, Sukang, and Younbaek. Particle size of flour positively correlated with ash, damaged starch, and lightness value(L*) of flour. In protein characteristics, Protein content of SW and commercial flour for baking cookie(Com5) was similar to Baekjoong, Jinpoom, Milsung, Olgeuru, Saeol, and Uri. SDS sedimentation volume based on a constant flour weight(SDSS) of KWC was lower than those of DNS and Com3. Mixing time and maximum dough height(Hm) of KWC were higher than those of imported wheat and Com. Protein content positively correlated with SDS sedimentation volume and water absorption of mixograph. SDS-sedimentation volume positively correlated with water absorption of mixograph, mixing time of mixograph, and height of dough development. In starch characteristics of flour, ASW(Australian standard white) flours showed lower amylose content, higher peak viscosity, breakdown, and setback in pasting properties than other flours. KWC flours showed higher amylose content and lower peak viscosity than those of AH(Australian hard), ASW, commercial flour for making white salted noodles(Com1), commercial flour for making yellow alkaline noodles(Com2) and Com3.

Puroindoline alleles, grain characteristics, milling performances and physical properties of flour of 22 Korean wheat cultivars were evaluated to determine the influence of puroindolines genotypes on grain and flour characteristics and to provide useful information for improving milling and end-use quality in Korean wheat breeding programs. Nine Korean wheat cultivars carried with Pina-D1a/Pinb-D1a, 11 cultivars had Pina-D1a/Pinb-D1b and 2 cultivars were Pina-D1b/Pinb-D1a. Korean wheats carrying with Pina-D1a/Pinb-D1a genotypes showed lower test weight and thousand kernel weight, area and roundness of grain and hardness index in grain characteristics, lower flour yield and higher proportion of break flour in milling performances and lower average particle size of flour, ash and damaged starch content, water retention capacity, yellowness-blueness and higher lightness of flour than wheats with Pina-D1a/Pinb-D1b or Pina-D1b/Pina-D1a genotypes. Pina-D1a/Pinb-D1b genotypes showed lower 1000-kernel weight, grain area, higher average of particle size of flour, higher ash and damaged starch content than Pina-D1b/Pina-D1a genotypes. There was no difference in hardness index of grain, milling performances, flour color between Pina-D1a/Pinb-D1b and Pina-D1b/Pina-D1a genotypes. These results could present the information to improve milling quality and physical properties of flour in Korean wheat breeding programs.

Flour characteristics and end-use quality of 10 commercial flours produced from Korean wheat (Kcom) were evaluated to utilize information for assessment consumer's satisfaction with Korean wheat compared with commercial flour from imported wheats (com). Two types of Kcom, whole wheat flour and white wheat flour, were found in market. Whole wheat flours showed higher ash and protein content, lower lightness and higher water absorption in mixogram than white wheat flours. Amylose content of Kcom was similar to that of com, but peak viscosity and breakdown of Kcom was lower than those of com. Noodle dough sheet prepared from white flours of Kcom was thinner thickness and higher lightness than those of whole wheat flours. Compared to com, Kcom showed lower lightness of noodle dough sheet. Hardness of cooked noodles of Kcom was similar to com for making noodle flours. In bread baking, Kcom showed lower loaf volume and lightness of crumb and higher firmness of crumb compared to com for baking bread.
