This study was conducted to investigate the effect of the addition of moroheiya powder on the baking qualities of the bread. Three different powder concentration levels of $0.2\%,\;0.5\%\;and\;1.0\%$ were added to flour to make the bread. The volume of the bread dough containing moroheiya powder tended to be increased compared to that of control during the fermentation period. The percentage of baking loss of the bread containing moroheiya powder tended to be less than that of control. In the texture analyzer measurement, the hardness of the bread was significantly increased by adding the moroheiya powder Springiness, gumminess and brittleness of the bread tended to increase and were all higher in the bread containing $0.5\%$ moroheya powder than in the other breads. In sensory evaluation, the bread containing $0.2\%$ moroheiya powder showed a similar tendency with control and showed the best scores, especially in taste.

The purpose of this thesis was to understand the various kinds of Korean liquors. To do this, about fifty different kinds of liquors and wines presented in Yi-dynasty literatures were reviewed and classified into several categories. The findings of the study are as follows, 1, Liquors of Yi-dynasty can be classified into three groups; Chungju or Takju which is brewed from rice or glutinous rice, Jeungryuju(Soju) which is made by distillation of Chungju or Takju, and Hwahyangju that is made by addition of fruits, fragrance, or medicinal plants in Chungju, 2. The basic method of making these liquors is in general to make yeast first and fix a liquor base by mixing rice or glutinous rice and yeast, and then add more rice or glutinous rice into the liquor base, and finally ferment the mixture for certain periods. On fixing a liquor base, several methods of rice preparations were used; these were white rice cake, rice paste, boiled dough of rice powder, and steamed rice. 3. Duration of fermentation was in general one to three weeks. However, the shorter one was completed within 3 days and the longer one required even one year or more. 4. Of Hwahyangju the ones with medicinal plants can be divided into several groups according to their medical effects; wines for mental and emotional stability, making blood and active circulation, increase in body stamina, promoting health and living long-life, treatment of stomachache and bruise, and enhancement of the functions of body organs, especially eyes ana ears.5. These liquors and wines above were brewed for daily use or special occasions (Sesiju).

This study was accomplished to examine possibilities to apply Korean medicine to breamaking. Extracts of Chungpesagan-tang prepared by the prescription of Korean medicine were used for baking, instead of water among ingredients of baking. Effects of addition of extracts of Chungpesagan-tang on various baking properties were analyzed during the process of baking. Changes in pH values and volumes of doughs during fermentation and pH values of bread showed no differences among samples. Loaf volumes and specific loaf volumes were increased somewhat on addition. The values of cohesiveness, springness, gumminess and brittleness of breads, which were measured by rheometer, were increased on addition while those of hardness were decreased a little. Lightness values of sections of loaves were decreased on addition, but their color differences were increased largely on color difference meter. There were nearly little differences among samples in all the values of parameters of external and internal characteristics and eating qualities of breads by sensory evaluation. Re-purchasing attitude of pullman bread added with Chungpesagan-tang had a high in the gender and age.

This study was designed to investigate the effect of cranberry powder making pan bread. Cranberry powder at the level of 1 % (CP1), 3% (CP3), and 5% (CP5) was mixed with flour to make the breads. According to mixograph, the control, CP1 and CP3 except CP5 were found to bo proper between 3 and 5 min. in tenn of peak time (min). All samples for peak value were at the level of over 60% It meant that all samples were proper to make bread. By increasing the ratio of cranberry powder, pH, dough fermentation rate, volume and specific volume were decreased, and adhesiveness, springiness, cohesiveness and resilience except hardness were decreased in texture profile analysis. In crumbScan analysis, the addition of cranberry powder decreased the volume and increased crumb fineness of pan bread. In sensory evaluation, CP1 and CP3 showed good preference in aspect of flavor, taste, and overall acceptance.

본 연구는 오미자청을 쌀가루에 첨가해 sourdough를 제조하여 이화학적 특성을 살펴봄으로써 제빵 이용 가능성에 대한 기초 자료를 얻기 위해 시도되었다. 오미자청, 비발효 쌀가루, 쌀가루 sourdough의 pH와 총산도, 효모와 유산균수, 팽창률, 호화 특성을 살펴보았다. 쌀가루 sourdough의 pH는 발효 시간이 경과할수록 유의적(p<0.05)으로 감소하는 경향을 보인 반면, 총산도는 유의적으로 증가하였다(p<0.05). 효모, 유산균수는 발효시간이 경과함에 따라 유의적으로 증가하는 경향을 보였다(p<0.05). 오미자청 쌀가루 sourdough의 최고 팽창률은 80%, 쌀가루로만 발효시킨 쌀가루 sourdough의 최고 팽창률은 52%인 것으로 나타났다(p<0.05). RVA에 의한 오미자청 쌀가루 sourdough의 호화 특성은 발효시간이 경과할수록 최종점도와 setback 값이 감소한 것으로 보아, 오미자청 쌀가루 sourdough를 이용 시 노화 지연 효과가 있을 것으로 사료된다. 따라서 본 연구의 결과로 보아 오미자청을 쌀가루 sourdough 발효 시 첨가해 줄 경우, 풍부한 효모와 유산균으로 인해 보다 위생적으로 안전하게 sourdough 제조가 가능할 뿐 아니라, 팽창률이 높아 제빵 시 이용할 경우 쌀가루의 단점은 개선시킬 수 있을 것으로 기대된다.

Whole forage sorghum (saccharatum) cultivar FS5 was harvested at the soft dough ($303{\pm}9g\;kg^{-1}$ DM) stage of maturity. The sorghum was chopped into approximately 20 mm pieces and ensiled under laboratory conditions in 1.5 L Weck glass jars. At ensiling, it was treated with two commercial silage inoculants: Pioneer 1188 (Inoculant A) and Eco-corn (Inoculant B). The inoculant A and B was applied at ca $2{\times}10^5$ or $2{\times}10^4$ colony forming units $g^{-1}$ DM., respectively. Silage with no additives served as a control. Three jars per treatment were opened on days 2, 4, 8, 15 and 60 post-ensiling to study fermentation dynamics. After 60 days of ensiling the silages were analyzed and subjected to an aerobic stability test lasting 5 days. Results showed that both inoculants caused a more rapid rate of pH decrease and a higher amount of lactic acid production. All the silages were well preserved and were stable upon exposure to air. Inoculants did not influence (p>0.05) the ash and total N contents, but tended to reduce acetic acid (p<0.05), butyric acid (p<0.01) and propionic acid (p<0.01) contents, and to increase the lactic acid content (p<0.01). The lower DM content of silages treated with Inoculant A agrees with the greater gas loss resulting from the DM loss, which was in good agreement with the higher yeast counts upon aerobic exposure. Silage treated with inoculant B had the highest DM (p<0.05) and lactic acid contents (p<0.01), and the lowest acetic acid content (p<0.05), which agrees with the rapid reduction of pH and smaller gas loss. Inoculant B reduced the ADF (p<0.01), ADL and NDF (p<0.05) contents, which also indicates smaller losses of organic soluble material. The control silages contained the highest levels of volatile fatty acids but no lactic acid, indicating secondary fermentation. It was concluded that both inoculants may improve the fermentation process, since silages from all treatments were stable upon aerobic exposure, noadvantage could be attributed to any of the inoculants used.

This study was conducted to develope carbohydrate-based fat replacement for use in the preparation of non-(trans) fatty acid and low-caloric bread. Characteristics such as leavening height of batter, pH, titratable acidity, specific volume, sensory evaluation, shelf life and texture change of bread made using 11 types of carbohydrate-based fat replacements were measured. The 11 carbohydrate-based fat replacers (No. $1{\sim}11$) were prepared using maltodextrin as a base, and different ratios of calcium sulfate, ascorbic acid, sodium stearoyl lactylate and methyl cellulose. The pH was lowered and the total titratable acidity was increased after four hours of fermentation in the control and the samples of dough that contained the fat replacement. In addition, the leavening height of the control was 5.0cm (maximum) after two hours of fermentation and 4.6 cm after four hours of fermentation, which was similar to the heights observed when No.$9{\sim}11$ were evaluated. When the specific volume of the bread was evaluated, the 3% of fat replacement No. 10 produced the best results. When taste was evaluated, there was no significant difference between the control and the bread produced using 1% No. 10, however, there was a significant difference between the control and all samples that contained 2% or more of the fat replacement. Furthermore, the addition of a greater concentration of the fat replacer resulted in a greater moisture. However, there were no significant differences in the color of the control and any of the samples. Additionally, measurement of the firmness of the bread during four days of storage at $25^{\circ}C$ revealed that it decreased as the concentration of fat replacer increased. In addition, the sample that contained 3% of sample No. 10 showed a firmness of 18kgf after three days of storage, while the control showed a firmness of 18kg after two days, which indicates that the degradation of the bread that contained the fat replacer was delayed by one day. The bread made using fat replacers was found to have a better taste, flavor, color, texture and firmness than the control, and the best results were observed in response to the addition of 3% of replacement No. 10. The results of this study will be useful in the production of non-(trans) fatty acid, low caloric bread.
