This study used Omija extract as a natural congelation to compare and analyze soybean curd's physicochemical and sensory quality characteristics in order to improve functional benefits and taste of soybean curd. When Omija extract concentration increased, protein content went up considerably while crude fat and yield significantly decreased. In the pH change, the group with Omija extract were lower than control and the change was not much noticeable but slightly checked as the storage period was extended. The turbidity tended to increase as the storage period was longer. In the acidity change, the group with 0.5% Omija extract showed rapid increase on the 4th day after starting storage, and it can be interpreted that decomposition started at the moment. As the storage period was extended, brightness and yellowness remarkably decreased and redness considerably enhanced: higher concentration Omija extract worked to decreased brightness and to increase yellowness and redness. In accordance with the storage period, hardness, brittleness and gumminess increased and springness decreased, but there was no considerable change in cohesiveness: in accordance with the concentration, hardness, brittleness and gumminess significantly increased, but there was no considerable change in cohesiveness. In terms of sensory quality, the group with 1% of Omija extract showed the best appearance, flavor, taste and after swallowing results. The group with 1% Omija extract was the most preferred, $4.89{\pm}0.32$ in the overall preference. In conclusion, adding Omija extract can improve soybean curd's physicochemical and sensory quality characteristics. Moreover, the extracts can be expected to play an important role in encouraging Omija's value and widening its appliances to various food.

The roots of Rosa rugosa have been used to treat diabetes mellitus in the folkloric society of Korea. To demonstrate the active component for the rat obesity induced by high fat diet for 6 weeks, the phytochemical fractionation and the pharmacological activity test were performed on this crude drug. It was shown that the methanolic extract and its EtOAc fraction inhibited the weight increase of the rat body, abdominal fat pad and hyperlipidemia at 200 mg/kg dose. Further, the triterpenoids, euscaphic acid and tormentic acid, isolated from R. rugosa roots were active at 30 mg/kg in the same assay. The two components shifted serum total-, HDL, and LDL-cholesterol levels toward the values of the unteated group, suggesting that the active compounds has hypolipidemic effects. The rats fad euscaphic acid and tormentic acid also reduced thiobarbituric acid-reactive substance (TBARS) and hydroxyl radical in the rat blood and increased superoxide dismutase activity compared to the control. TBARS values and carbonyl contest of the hepatic protein were reduced by treatment with the two triterpenoids. Antioxidative enzyme (SOD, glutathione peroxidase, and catalase) activities in hepatic were increased by treatment of rats with the triterpenoids, which suggests that triterpenoids inhibited the reduction of hepatic antioxidative activity caused by high fat diet. Taken together, these results support that euscaphic acid and tormentic acid improve a high fat diet-induced hyperlipidemia via the activation of antioxidative mechanism.
Objective: The objective was to evaluate the efficacy of increasing supplementation of Yarrowia lipolytica (YL) up to 3.0% replacing 1.6% poultry fat and 0.9% blood plasma for growth performance, intestinal health and nutrient digestibility of diets fed to nursery pigs. Methods: Twenty-four pigs weaned at 24 d of age (initial body weight at 7.2±0.6 kg) were allotted to three dietary treatments (n = 8) based on the randomized complete block. The diets with supplementation of YL (0.0%, 1.5%, and 3.0%, replacing poultry fat and blood plasma up to 1.6% and 0.9%, respectively) were fed for 21 d. Feed intake and body weight were recorded at d 0, 10, and 21. Fecal score was recorded at every odd day from d 3 to 19. Pigs were euthanized on d 21 to collect proximal and distal jejunal mucosa to measure intestinal health markers including tumor necrosis factor-alpha, interleukin-8, immunoglobulin A and immunoglobulin G. Ileal digesta was collected for apparent ileal digestibility (AID) of nutrients in diets. Data were analyzed using Proc Mixed of SAS. Results: Supplementation of YL (1.5% and 3.0%) replacing poultry fat and blood plasma did not affect growth performance, fecal score and intestinal health. Supplementation of YL at 1.5% did not affect nutrient digestibility, whereas supplementation of YL at 3.0% reduced AID of dry matter (40.2% to 55.0%), gross energy (44.0% to 57.5%), crude protein (52.1% to 66.1%), and ether extract (50.8% to 66.9%) compared to diets without supplementation. Conclusion: Yarrowia lipolytica can be supplemented at 1.5% in nursery diets, replacing 0.8% poultry fat and 0.45% blood plasma without affecting growth performance, intestinal health and nutrient digestibility. Supplementation of YL at 3.0% replacing 1.6% poultry fat and 0.9% blood plasma did not affect growth performance and intestinal health, whereas nutrient digestibility was reduced.

But between all fermented feed groups were a little difference in partly. 5) On the influence of fowl meat composition, amount of moisture contents was a little decrease in fermented feed groups, and crude protein and crude fat were increased. 6) Feed conversion rate resulted a little amount decreasing. Specially, 10% Asp oryzae koji group was lowest (2.89) compare with control (3.35) 3. As a result of economical analysis appeared highest low income in koji groups. Low income were more gained percent of 40.22 in 10% Asp oryzae koji and 33.19 in 10% Asp. niger koji than control.
Chemical properties and physiological activities of the freeze-dried synnemata of Beauveria bassiana were examined. A proximate analysis showed that the synnemata consisted mainly of carbohydrate (49.86%), protein 11.36%), and a moisture content of 30.64%. It contained a low amount of crude ash (4.76%) and fat (3.38%). The carbohydrate was composed mainly of mannose (52.3%), galactose (31.5%), glucose (13.2%), and rhamnose (3%). Trace amounts of arabinose, xylose, and fructose were present. Major amino acids In the synnemata were glutamic acid, glycine, aspartic acid, arginine, threonine, alanine, valine, leucine, lysine, and aspartic acid with the amounts of 30.42, 25.22, 17.17, 15.12, 12.65, 15.23, 12.47, 11.47, 14.24, and 17.17 mg/g, respectively. Among extracts from the synnemata, the hot-water extract showed 67% of anticomplementary activity compared to that of the positive control, followed by ethyl acetate extract (17%) and methanol extract (15%). The hot-water extract also had anticoagulant activity with 55 sec of coagulating time and this fraction exhibited the most potent Intestinal immune system modulating activity. The methanol extract showed the highest inhibitory activity (25%) on the 12-O-tetradecanoyl phorbol-13-acetate-induced superoxide ($O_2^-$) generation, followed by hot-water extract (18%) and ethyl acetate extract (10%). The data in the present study indicate that the extract of Beauveria bassiana synnemata contains some healthful chemical ingredients and it could provide beneficial physiological activities. These features of the synnemata should be of interest to the food industry as well as other industrial fields.

A trial was conducted to determine the effect of low crude protein (CP) diets with constant metabolizable energy to crude protein (ME:CP) ratio on growth, body composition and nutrient utilization of broiler chicks from 1 to 26 days of age. Four dietary treatments having four levels of CP and ME as 23, 22, 21 and 20% and 3,036, 2,904, 2,772 and 2,640 kcal/kg, respectively, were formulated and a ME:CP ratio of 132 was maintained in all the diets. Digestible lysine was maintained at 1.10 of the diet. A total of 1,760 day-old Hubbard broiler chicks were randomly divided into 16 experimental units and each diet was offered to four experimental units at random. Feed intake was increased (p<0.05) while weight gain and feed conversion ratio were adversely affected (p<0.05) when the diets with low CP and ME were fed to broilers. Total protein intake and total ME intake were linearly decreased (p<0.05) and protein efficiency ratio and energy efficiency ratio were lower (p<0.05) than in the chicks fed dietary regimen with 22% CP and 2,904 kcal/kg ME. The whole body analysis of the birds revealed that chicks fed the lowest dietary regimens retained less (p<0.05) nitrogen and more ether extract than chicks fed the control diet, however, body dry matter, total body ash and fat free body protein were not affected. Similarly, protein and energy utilization were also unaffected by the dietary treatments. In summary, chicks fed low CP diets with constant ME:CP ratio grew slower, used feed less efficiently and retained less protein and more body fat than chicks fed the control diet.
