This study is to find out the effects of the qualify of the breads made from Korean and imported wheat flour respectively after adding chitosan, by examining the dough making, the bread making properties, the Physicochemical properties of the breads. The low polymerized chitosan (M. W. : 37,000) was added respectively 1, 3 and 5% in the form of 10% lactic acid aqueous solution. The Korean wheat bread had 4% more water, 3% more sugar, 0.5% more salt, 3% more margarine and 1.5% more yeast per 100% to wheat flour added than the imported wheat bread. The bread volume for the two groups stayed the same. The water absorption in the chitosan added group was increased more greatly than in the control group, however, pH was reduced. In case of color among all wheat bread groups the ‘L’ value appeared to be higher in the imported wheat bread groups, and the ‘b’ value appeared to be higher in the chitosan added group.

우리나라에서 생산되는 우리밀을 이용하여 한국형 사워종을 제조하며, 동시에 각각의 글루텐 함량, pH, TTA, 발효율과 mixograph를 측정하고 분석하여 그 중 가장 우수한 sourdough starter를 추출하였다. 그리고 그 starter를 이용한 sourdough bread를 제조하였을 때 나타나는 제품의 특성을 CrumbScan을 통하여 비교 분석하여 우리밀을 이용한 한국형 사워빵의 특성을 알아보았고, 이용할 수 있는 가능성을 알아보고자 하였다. 글루텐 함량분석 결과 강력밀가루와 우리밀 중에서는 KWF 5와 KWF 6이 제빵에 적합한 글루텐 함량을 가지고 있었다. 전반적으로 sourdough starter의 pH 범위는 $4.0{\sim}4.5$ 사이로 사용하기에 적당하였고, TTA값은 대조구와 비교해 봤을 때, 비슷하거나 높게 나타났다. 발효율은 24시간 후 가장 많이 팽창한 것은 KWF 5와 KWF 6이었고 48시간 후에는 반죽의 산성화로 인하여 오히려 감소하는 것이라 사료되었다. mixogram의 분석결과는 강력밀가루가 제빵적성에 적합한 것으로 나타난 반면에 우리밀의 경우는 반죽내구성이 낮고 단백질함량이 적어 빵을 만들기에는 적합하지 않았다. CrumbScan을 통한 영상분석의 결과 강력밀가루와 우리밀 7가지 중에서 기공의 조밀도가 크고 찌그러짐이 적은 KWF 5와 KWF 6이 sourdough starter로 사용하기에 적합한 것으로 나타났다.

This study was conducted to evaluate the characteristics of bread and the rheology of flour dough containing jochung. In the farinogram test, the addition of jochung changed water absorption, development time and mixing tolerance index for making bread As the amount of jochung increased, the water absorption, mixing tolerance index decreased and the development time increased. In the extensograph test, the degree of extension decreased with increasing of jochung content whereas degree of resistance was enhanced with addition of jochung. After fermentation treatment, the volume of the dough with 20% sucrose were less than that of the dough containing 20% of jochung. The dough with 5% jochung showed the lowest dough raising power compared to the other doughs. The bread consisting of 15% jochung showed the highest volume of loaf and specific volume. Therefore, high quality of bread can be achieved by adding jochung instead of sucrose for making bread.

This study investigated the bread-making properties of rice bread supplemented with HPMC (hydroxypropyl methylcellulose) 1~3% and gluzyme (glucose oxidase), fungamyl (fungal ${\alpha}$-amylase) and pentopan (xylanase+hemicellulases) (0.0015~0.0090%). The viscoelastic properties of the dough with HPMC 1~3% were analyzed. When the rice flour was supplemented with HPMC 1~3%, the viscoelastic properties of the dough tended to increase as the amount of added HPMC was increased. The physicochemical characteristics of the rice bread with HPMC, gluzyme, fungamyl, and pentopan were analyzed. Supplementing the rice flour with HPMC, gluzyme, fungamyl, and pentopan had a significant effect on the volume (p<0.01) and specific volume (p<0.001) of the rice bread. Supplementing the rice flour with 3% HPMC and 0.0045% or 0.0090% pentopan had a significant effect on increasing the volume (p<0.01) and specific volume (p<0.001) of the rice bread. Supplementing the rice flour with 3% HPMC, 0.0023% gluzyme and 0.0015% fungamyl had a significant effect on increasing the volume (p<0.01) and specific volume (p<0.001) of the rice bread. These results suggest that supplementing the rice flour with HPMC, gluzyme, fungamyl and pentopan is effective for the production of rice bread.

The present study examined optimal level of mulberry leave powder, and the method of bread-making were proposed to utilize mulbery leave powder by investigating rhelogical properties of dough and sensory evaluation of bread. The difference of amino acids compositions in flour brew were also investigated by fermentation of S. cerevisiae or bifidobacteria. As the % of mulberry leave powder increases absorption rate of dough was steadily increased, but stability and R!E ratio if dough were dramatically decreased more than 1% leave respectively. R!E ratio value, which indicates gas retnetion property of dough, was not obtained at the level 5%. Gelatinization temperature and maximum viscosity temperature showed a tentency of decrease, resulting in easier cooking of dough. The delay of temperature cauesd by addition of mulberry leave powder was overcome by two step bread making, that is, modified straight dough method adding flour brew fermented 16hrs by bifidobacteria. The firmness of bread was progressively dreased as the amount of mulbery leave powder increased. The addition of 2% level of mulberry powder to bread showed no significant difference comparing with control in sensery evaluation. Amino acids compositions of Flour brew fermented by bifidobacteria was superior th that by S. cerevisae nutritionally.onally.

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.
