This study was conducted to investigate the effect of 0.5% calcium lactate(CaL) on the fermentation of dough and quality and shelf-life of bread. Calcium lactates(CaL-A and CaL-P) were prepared from ash of black snail which contained shell and tissue together(ABS) and powder of the snail(PSB). pH of dough with the CaLs were higher than that of the control and, volume of the dough, loaf volume of bread were lower than those of the control products. But the volumes were almost the same when the pH of the dough were adjusted to pH 5.5. Mean calcium contents of treated bread (39.36~49.70 ㎎/100g) were higher than that of control products(13.43 ㎎/100g). There was no difference in Hunter L^(*), a^(*), b^(*) values between the control and the treated group. Hardness and gumminess of CaL-A treated bread were the highest, but springiness and cohesiveness were the lowest. All the attributes showed no difference in case of pH adjustment(pH 5.5). The smaller pore and larger air cell with rough surface were observed in the CaL treated bread by SEM analysis. Sensory scores of CaL treated bread showed relatively lower values than those of the control products, but the scores increased by pH adjustment. The shelf-life of bread with CaL-P and CaL-A at 20℃ were 4 and 3 days, respectively, while that of the control group 1 day.

The quality characteristics of baguette bread added with water extracts of Liriopis tuber(LT) and effect of the diets containing 20% dried and powered baguette with 10% LT on the level of blood sugar and lipids in the diabetes induced rat by streptozotocin were investigated. pH of the dough added with 5~10% LT was 5.00~5.03 which were lower than that of control(5.12). The volume of the dough with 10% LT after 2nd fermentation was the biggest. Loaf volume index of the bread with 10% LT was significantly higher than that of control. L^(*) values of outside and inside of the baguette decreased in proportion to the increase of the LT, while the a^(*) values increased. Color of the bread with LT showed light dark-red. There was no significant difference in hardness, but springiness and gumminess were higher in the bread with 10% LT. Sweet taste increased, color acceptability and overall taste were enhanced by addition of LT, but it did not affect the sour and astringent taste. The overeating phenomenon showed in the diabetes rat decreased in the group fed with baguette bread with LT, while feed efficiency increased by feeding of the bread with LT. The level of glucose, neutral lipid and total cholesterol in blood were 118.92, 95.47 and 37.42 ㎎/dL in the control group, 245.60, 121.54 and 102.43 ㎎/dL in the diabetes control, 148.40, 103.25 and 57.63 ㎎/dL in the baguette diet group, respectively. There was no significant difference of HTR between control group and baguette diet group, while atherogenic index was considerably decreased, which might represent improving and preventing effects of diabetes.

The effect of water extracts of Chungkukjang(WEC: 10%, w/v), which was prepared using Bacillus subtilis isolated from Korean traditional Chungkukjang, on the pH, acidity and volume of the dough, and loaf volume index(LVI), color, texture, retrogradation degree, microscopic observation and sensory quality of the bread were investigated. Experimental plots were divided to 3 groups(Control; without WEC, Ⅰ; added 2.5% WEC against total amount of water, Ⅱ; added 5.0% WEC against total amount of water). There were no significant difference in pH and acidity among each experimental groups. Dough volume were higher but LVI were lower in the Ⅰ- and Ⅱ-bread than those of control group. L^(*) values of the top crust and internal tissue in the Ⅰ-and Ⅱ-bread were lower than those of control group. The higher addition amounts had the lower L^(*) values. Hardness, strength, gumminess and brittleness were higher, but cohesiveness and springiness were lower in the WEC-breads than those of control. In the results of microscopic observation, there were scarce of the bigger starch granules and a sparse structure, while there were smaller starch granules in the WEC-bread. The scores of crispy taste of the WEC-bread were lower than those of the control group, but there were no significant difference in tenderness, odor, savory taste and overall acceptability between the control and the Ⅰ-bread. The retrogradation rate of the bread stored for 3 days at 25t was 45.09% in control, 17.92% in Ⅰ-bread, and 12.45% in Ⅱ-bread, respectively.

The effect of hemicellulose extracted from Shiitake mushroom(Lentinus edodes) on the level of blood sugar and cholesterol in the diabetes-induced rat by streptozotocin(STZ) was investigated. The yield of hemicellulose by extraction process of 5% salt extraction, preparation of alcohol insoluble substance, 1N KOH extraction, acid precipitation(pH 3.0), and dialysis was 9.24%. The experimental plots divided to 1% cellulose group(control), 0.5% hemicellulose group(H-1) and 1% hemicellulose group(H-2). The groups were fed for 6 weeks, then continuously fed for 1 week after induction of diabetes by STZ. Feed intakes, weight gain and feed efficiency of the each groups were not significantly different, while water intakes and liver weight of H-2 group were lower than those of control and H-1 group. Weight of liver in the H-2 group was significantly lower than those of control and H-1 groups. The amounts of feces were 0.32 g/day in the control group, 0.43~0.44 g/day in the H-1 and H-2 groups, while the amounts of urine were 15.28 mL/day in the control group, 10.83~11.20 mL/day in the H-1 and H-2 groups. The content of blood glucose before diabetes induction(fed for 3~5 weeks) was 111.2~132.6 ㎎/dL in the control group, not significantly different from others. After diabetes induction, however, the contents were 212.8 ㎎/dL in the control group, 140.0~144.0 ㎎/dL in the H-1 and H-2 groups, which showed significant difference. Urine glucose contents of H-2 group before and after diabetes induction were lower than those of control and H-1 groups. There was no significant difference in the content of neutral lipid between each groups. Total cholesterol contents were 101.6 ㎎/dL in the control group, 56.2~64.0 ㎎/dL in the hemicellulose groups. HDL-cholesterol content and atherogenic index of hemicellulose groups were lower than those of control group, respectively. In conclusion, the hemicellulose extracted from Shiitake mushroom represented improving and preventing effects for diabetes.

This study was conducted to investigate the extraction characteristics of the polysaccharide from Jeseng mushroom (Fomitopsis pinicola Jeseng). Yields of the polysaccharide extracted from powdered mushroom by autoclaving(120, 30 min) with water at different pH and salt concentration were 8.2~9.2% in pH 5~11, 4.7~5.5% in 1.5% salt solution, respectively. The yield by the 0.05~1.0 N KOH-extraction was ranged 3.45~13.20%, while that by HAS-extraction(homogenizing after KOH swelling) using 1~2.5 N KOH 73.6~78.4%. Content of carbohydrate, protein, lipid and ash of the crude polysaccharide extracted from fruits body and its cultured mycelium by method of water extraction, KOH extraction(0.005~1N) and HAS-extraction were ranged 86.5~92.6%, 2.3~13.1%, 0.1~4.2% and 0.1~1.7%, respectively. The polysaccharide were composed of 62.0~77.8 g/g of pentose, 138.0~187.8 g/g of hexose and 21.2~117.3 ㎎/g of protein. From these results, the polysaccharide extracted was supposed to be a protein-bound polysaccharide.
