  • In order to anticipate the physiological function of dietary fibers, glucose and bile acid retarding effects were experimented by using in vitro methods based on dialysis for commercial fibers and dietary fiber residue of food samples. The glucose retarding effect in commercial fibers increased in the order of alginic acid, guar gum, CM-cellulose, citrus pectin > apple pectin > $\alpha$-cellulose and the effect in food fiber residues increased in the order of sea mustard > Korean cabbage, apple > rice bran, barley, soybean, and tangerine. The bile acid retarding effect in commercial fibers increased in the order of citrus pectin, guar gum > CM-cellulose, alginic acid > apple pectin > $\alpha$-cellulose and the effect in food fiber residues increased in the order of barley, rice bran > sea mustard > tangerine > Korean cabbage, soybean > apple. The higher the retarding effect of glucose movement through the dialysis membrane, the more effective the control of the human blood glucose level. As the retarding effect of bile acid movement across the dialysis membrane increased, the human serum cholesterol level correspondingly reduced. Consequently these in vitro methods can be used as a preceding test before undertaking animal and human experiments to predict the physioloical effects of fiber residues from diverse food samples as well as commercially refined fibers.

  • Fifteen Inner Mongolian wethers with permanent ruminal and duodenal cannulas were used to study the effects of dietary rumen-undegradable protein (RUP) to rumen-degradable protein (RDP) ratios or protein sources on fiber digestion in the gastrointestinal tract and ruminal fluid characteristics. Fiber digestion and ruminal fermentation were not affected (p>0.05) by dietary RUP to RDP ratios (from 1.54 to 0.72). Soybean meal supplementation improved ruminal digestion. Fish meal supplementation increased (p<0.05) the ruminal degradability of fiber. The different RUP to RDP ratios (from 1.54 to 0.72) did not influence (p>0.05) ruminal fluid pH, but there were differences (p<0.05) in ruminal fluid $NH_3-N$ concentration because of urea replacement. Soybean meal as a dietary protein source decreased (p<0.05) ruminal fluid pH and increased (p<0.05 or p<0.01) $NH_3-N$, acetate, propionate and butyrate concentrations in the rumen. Fish meal as a dietary protein source decreased (p<0.05 or p<0.01) ruminal $NH_3-N$ and acetate concentrations and increased (p<0.05) ruminal propionate concentration. It can be concluded that dietary protein sources have more significant effect on fiber digestion and ruminal fermentation than different dietary RUP to RDP ratios, when the dietary crude protein requirements of growing sheep are satisfied.

  • Dasik is a type of Korean traditional confectionery that is kneaded with various grains, nuts or herb flour and honey and then pressed with a decorative press. Soybeans are a rich in protein, lipids, dietary fiber, minerals and fat soluble vitamins. Spirulina is a functional food that contains protein, lipids, carbohydrates, minerals, vitamins, dietary fiber and pigments. In this study, soybean Dasik containing spirulina was developed in an attempt to provide an easy method of incorporating spirulina into daily dietary life. In addition, we evaluated the quality characteristics of the soybean Dasik with spirulina that was developed here. Specifically, 0, 10, 20 and 30% spirulina was added to the soybean powder that was used to prepare soybean Dasik. Soybean Dasik that contained 30% spirulina had a higher moisture content and lower hardness when compared to other groups. In addition, the L, a and b value decreased as the level of spirulina increased. Furthermore, the antioxidant activity of soybean Dasik increased according to the increase in the addition of spirulina. Specifically, the $IC_{50}$ values of the DPPH and hydroxyl radical scavenging activity of the control group were 76.6 mg/mL and 100.7 mg/mL, respectively, whereas these values were 26.3 mg/mL and 32.9 mg/mL, respectively, in Soybean Dasik that contained 30% spirulina. When a sensory evaluation was conducted, the overall preference decreased as the level of added spirulina increased. When the buying intension was evaluated, the control group had the highest score (7.8), followed by that of the Dasik that contained 20% spirulina (7.2) The buying intention was lowest for the Dasik that contained 30% spirulina. In conclusion, Soybean Dasik that contained up to 20% spirulina would be maketable.

  • This study was conducted in order to establish an in vitro method simulating the physiological function of fibers along the large intestine of humans. Commercial fibers including guar gum, apple pectin, citrus pectin, CM-cellulose, alginic acid and $\alpha$-cellulose, and dietary fiber residues obtained from rice bran, barley, soybean, Korea cabbage, apple, tangerine and sea mustard were employed to determine the water-holding capacity, weight of hydrated residue and fiber content after anaerobic fermentation using human fecal inoculum for 24 hours, followed by dialysis under osmotic suction pressure. The weight of hydrated residue in commercial fibers was in the decreasing order of CM-cellulose > alginic acid, $\alpha$-cellulose > apple pectin, citrus pectin > guar gum and that in food fiber residues was in the decreasing order of rice bran, sea mustard > soybean > tangerine, Korean cabbage > barley > apple. It was demonstrated that the larger the weight of hydrated residue was, the more the weight of human stool increased. Consequently this in vitro method can be used as a preceeding test before undertaking animal or human experiment to predict the physiological effects of fiber residues from diverse food samples as well as commercially refined fibers.

  • The content of total dietary fiber in biji dried by hot air was 65.40%, and the percent of insoluble fiber and soluble fiber in total dietary fiber was 63.60% and 1.80%, respectively. In testing the feasibility of biji as a fiber source in cake, cakes were prepared with flour substituted with biji powder at the level of 0%, 5%, 10%, 15% and 20%. The Hunter value showed that the crumb colors of the cakes with 10%, 15% and 20% biji powder were significantly different from the control. The specific volume of the cake with 20% biji powder was significantly lower tan the other cakes. Cakes with 5%, 10% and 15% biji powder were les hard than the control after 10 days storage at 2$0^{\circ}C$. Sensory evaluations showed that their characteristics - crumb color, crumb texture, moistness, softness and overall preference - were significantly influenced by the replacement of flour with 10%, 15% and 20% biji powder. However, there was no difference in softness and overall preference of the cake prepared with 5% replacement compared to the control.

  • This study investigated preferences toward soybean-based foods and levels of dietary isoflavone intake in female adults living in Daegu. In order to determine the subjects' attitudes toward soybean-based foods their degrees of recognition and preference along with intake frequency were examined. To estimate their isoflavone intake levels, a food frequency questionnaire and the 24-hour recall method were used. The average age, height, weight, and BMI of the subjects were 47.3 years, 159.6 cm, 56.4 kg, and 22.1 kg/$cm^2$, respectively. And their mean energy, protein, dietary fiber, calcium, and sodium intakes were 1,871.9 kcal, 81.1g, 23.2 g, 604.7 mg, and 5.07 g, respectively. The average amount of isoflavones consumed from soy foods was 29.49 mg/day(daidzein 13.14 mg/day and genistein 16.35 mg/day) as assessed by food frequency questionnaire, and by the 24-hour recall method the average amount was 22.97 mg/day (daidzein 10.10 mg/day and genistein 12.87 mg/day), showing that the food frequency questionnaire assessment amount was 6.52 mg higher than that by 24-hour recall method. The major food sources of the isoflavones were soybean paste and soybeans. For the subjects' degrees of recognition of soybean food, soybean paste received the highest score among the items. The results also showed that the most preferred soybean-based foods were soybean paste stew and soybean paste soup. Furthermore isoflavone intake was significantly higher in the postmenopausal women than in the premenopausal women. Overall, these data help elucidate the patterns and determinants of soy food consumption and also provide an assessment of dietary soy isoflavone intake in Korean women.

  • This study was conducted to investigate correlation between soybean and their products consumption and risk factors for atherosclerosis in the healthyKorean adults. Health behaviors such as smoking, exercise, alcohol consumption and dietary patterns and nutrient intakes of 193 healthy adult subjects aged from 26 to 69 were assessed by using interview and semiquantitative food frequency questionnaire. The BMI, blood pressure and biochemical parameters of blood were examined as well as preferences for taste and family history of disease. Data were expressed as quartile according to soybean and their products consumption. The average daily soybean and their product consumption for 1st, 2nd, 3rd, and 4th percentile group were 36, 78, 112, and 182g, respectively. The more consumption of soybean and their products, the more intake of energy, protein, lipid, fiber, Ca, cholesterol as well as frequency of exercise, smoking and drinking. Serum TG, total cholesterol and LDL-cholesterol and AI as risk factors of atherosclerosis were positively correlated with smoking and drinking (p<0.05). Especially, serum TG was positively correlated with hypertension and BMI (p<0.01). But, no correlation between exercise, salty taste, meat preference, soybean products consumption and atherosclerosis risk factors was found, which means that life styles such as smoking and drinking rather than dietary habits might influence atherosclerosis in healthy adults. In conclusion, present soy products consumption should be increased by way of developing new generation soy products in order to exert anti-atherosclerotic effect by soybean in human.
