  • This study was carried out to examine the effect on the contents of dietary fiber, mechanical properties, and sensory quality of bread contained with 10% of high-fiber Camellia (Camellia japonica L.) seed flour. Bread added by dietary fiber was the contents of moisture, protein and ash higher than control bread, while the contents of lipid lower than that of control bread. The high-fiber with Camellia seed flour contained 8.6% soluble dietary fiber, 43.7% insoluble dietary fiber, and 52.3% total dietary fiber. The ratio of insoluble dietary fiber/soluble dietary fiber in the high-fiber with Camelia seed flour was 5 times. Bread with the addition of dietary fiber contained 6.9% total dietary fiber. With the addition of dietary fiber, water absorption , mixing time loaf weight, and hardness increased, but the loaf volume decreased . The sensory quality on bread added by dietary fiber was somewhat low in color, appearance, crumb texture, mouthfeel, flavor and overall preference was higher than that of control bread.

  • Three hull-less barleys and three covered barleys grown in Korea were pearled to give 0% and 60% yield, respectively. Whole barleys and pearled barleys were analyzed for total, insoluble, soluble dietary fiber and ${\beta}-glucan$ contents. Whole hull-less barleys contained average 17.1% total dietary fiber, and whole covered barleys contained average 23.9% total dietary fiber. Pearled hull-less barleys contained 9,2% total dietary fiber and 4.8% solule dietary fiber. Pearled covered barleys contained 11.9% total dietary fiber and 6.0% soluble dietary fiber. Whole barleys contained $3.2{\sim}3.9%$ (${\beta}-glucan$, and pearled barleys contained $3.5{\sim}5.4%$ (${\beta}-glucan$. Soluble dietary fiber and (${\beta}-glucan$ contents of barley were not affected by cooking, while insoluble dietary fiber content was increased by cooking.

  • Bacterial transformation of bile acids is possibly involved in colorectal carcinogenesis. n several epidemiological studies, the fecal bile acid dietary fiber are related to the indicence of colonic cancer. This study investigated the influence of age, dietary fiber intake on fecal bile acid profiles in healthy subject. The dietary fiber were assessed by mean of 24 hour dietary recall method, the subjects consist of 238 members aged 20 to 64 years old and feces are collected from the subjects. Fecal bile acids and neutral sterols were analyzed by gas chromatography. Mean dily crude fiber intake level was 7.7$\pm$1.4g(dietary fiber : 16.7$\pm$3.5g), dietary fiber intake range being 6.5-36.8g. The dietary fiber intake in elederly subject was significantly lower than in the other younger groups. Dietary fiber intakes was negatively correlated with the total bil acid concentation in feces. Probably, a decrease in dietary fiber intake results in higher fecal bile acid concentrations. The secondary bile acid concentration is related to the colon cancer, deoxycholic acid and lithocholic acid were significantly higher in elderly subjects. Concentration of fecal total bile acid, deoxycholic acid, coprostanol, coprostanone were higher in low dietary fiber intake group. These results suggest that the risk factor for colon cancer might be reduced, when dietary fibers are consummed more.

  • The effects of cooking on the dietary fiber content in rice, brown rice, yellow soybean and black soybean were investigated. The dietary fiber contents were analyzed by Prosky's method(AOAC method) after boiling, microwave heating and autoclaving of the sample. It was showed that the different cooking methods resulted in different effects on the insoluble dietary fiber contents. Except yellow soybean, cooking time had little effect on insoluble dietary fiber contets in the other samples. The contents of soluble dietary fiber were generally increased by cooking. Increased cooking time reduced the content of soluble dietary fiber in brown rice but increased in rice. However, no significant differences caused by cooking time were observed for soluble dietary fiber in black soybean. The effects of cooking method on the total dietary fiber contents were similar to those of insoluble dietary fiber. The reasons for this might be that the main fraction of total dietary fiber was insoluble forms and the content of total dietary fiber was calculated as the sum of insoluble and soluble dietary fiber content.

  • Various fractions of apple fibers such as crude pulp, total dietary fiber, soluble dietary fiber, and insoluble dietary fiber were prepared and added to the proteose peptone-yeast extract-fildes (PYF) media to see their effects on the growth of type cultures of intestinal bacteria. Most microbes tested in this experiment grew well in PYF media with the soluble dietary fiber of apple than with the insoluble dietary fiber. Especially Bifidobacterium species such as B. adolescentis, B. animalis, B. infantis, B. longum, B. thermophilum showed higher growth in PYF media containing the soluble dietary fiber than other fiber fractions. However, pectin-added media didn't promote the growth of most microbes used in the experiment. In the in vitro mixed culture using rat feces as starter, the addition of the soluble dietary fiber or pectin to the basal medium showed larger proportion of Bifidobacterium species in total bacteria than that of glucose.

  • Recent epidemiological observations suggested beneficial effects of dietary fiber on man's health. The obsective of this study was to obtain the dietary fiber reference data of mushrooms. The dietary fiber contents of six different mushrooms (Cornellus edodes, Auricularia auriculajudae, Gyrophora esculanta, Agaricus bisporus, Pleurotus ostreatus, Collybia velutipes) were analyzed by Southgate method, modified neutral detergent fiber (NDF) method and Food Research Institute (FRI) method. Duplicate sample were used for each determination. The mean values of total dietary fiber by Southgate method, modified NDF method and FRI method were respectively $20.08\pm1.45g$/100g dry weight, $20.24\pm1.85g$/100g dry weight and $21.5\pm2.70g$/100g dry weight. The mean values of all mushroom samples by FRI method were significantly different from the mean values of the samples by modified NDF method and Southgate method. However, there was no difference in the mean values of the samples between modified NDF method and Southgate method. By Southgate method, total dietary fiber of mushrooms composed of 1.7-3.1% soluble fiber, 47.0-66.6% hemicellulose, 28.4-57.7% cellulose and 0.9-3.3% lignin. By modified NDF method, total dietary fiber of mushrooms composed of 61.8-79.1% hemicellulose, 5.4-32.9% cellulose and 4.5- l5.5% lignin. Therefore, dietary fiber contents of mushrooms were mainly hemicellulose. Our values for total dietary fiber for six mushrooms were 2~4 times higher than crude fiber in textbook.

  • This study was performed to investigate the influence of dietary fibers from the whole foods on the serum lipid level and bowel function in rats. The fiber sources of experimental diets were prepared by drying and milling of cereal(rice bran), vegetables(Korean cabbage, radish), fruit(apple), and sea weeds(laver, sea tangle). Each of fiber sources was mixed into the diet to make the 5% level of total dietary fiber. Male rats of Sprague-Dawley strain were blocked into 8 groups : FF, CC, CE, V1, V2, ER, S1, and S2. The animals were fed ad libitum each of experimental diets for 4 weeks. Serum triglyceride level was not significantly different among groups. The laver group showed the lowest level in the serum total cholesterol. The Korean cabbage group showed the highest level in the serum HDL cholesterol. The longest transit time was observed in the fiber free group and the shortest transit time was observed in the sea tangle group. Absorption rates of calcium were especially lower in the Korean cabbage and the sea tangle groups than the other groups. Magnesium and phosphorus absorption rates were influenced by SDF(Soluble Dietary Fiber) intake and TDF(Total Dietary Fiber) intake, respectively. Mucosa weight in the small intestine showed the tendency to increase by increasing of IDF (Insoluble Dietary Fiber) intake. especially the Korean cabbage group was the heaviest. The activity of maltase in the mucosa of small intestine was the lowest in the radish group.

  • The effects of common Korean dietary fiber-rich foods(dried sea mustard, Lentinus edodes and Korean radish leaves) on total gut transit time of diet, serum cholesterol level and mineral apparent absorption ration and tissue level were investigated. Twenty eight male were divided into 4 groups and were fed a control diet(containing 2% cellulose) and three fiber supplementary diet mixed with 10% of the above dietary fiber rich foods for 4 weeks, respectively. Body weight gain and food efficiency ration were not affected by the supplementary diet of fiber but the total gut transit time of diet was shortened in all dietary fiber groups. The Lentinus edodes reduced significantly serum total cholesterol and increased the HDL-cholesterol/total cholesterol ratio at 4th week without and effect on calcium and iron apparent absorptions and tissue levels of the minerals. Radish leaves decreased significantly iron apparent absorption ration with a tendency to increase iron retention in spleen and did not alter serum cholesterol level. Serum cholesterol concentration and calcium and iron apparent absorptions were not significantly altered by the ingestion of sea mustard, while it had more soluble dietary fiber than mushroom and radish leaves.

  • One hundred twenty healthy college students and housewives from urban middle income household were investigated in terms of food consumption patterns, nutrient intake and dietary fiber intake. Total food intake was slightly lower in college students(1059.9g/d) than in housewives(1160.g/d) . However, the ration of animal food to total food was considerably higher in college students(23.7%) than in housewives(16.8%). College students tended to consume more dairly products, meat & products, and cereals & grain products but less vegetables , fruits, fish and shellfish than housewives. Although nutrient intake was not much different (except for total calories, fats, and ascorbic acid), dietary fiber intake was slightly and significantly lower in college students(14.9g/d, 8.3g/1000kcal) than in housewives(16.9g/d, 103g/1000kcal) . That is partially due to college students irregular food habits and the change in their meal patterns from traditional to western diets. There was a significantly positive correlation between dietary fiber intake and thiamin, riboflavin, niacin and crude fiber intake.
