We investigated the physicochemical and sensorial properties of hamburger patties made with three different defatted soybean flour (DSF) preparations which differed in particle size. Coarse ($Dv_{50}=259.3{\pm}0.6{\mu}m$), fine ($Dv_{50}=91.5{\pm}0.5{\mu}m$), and superfine ($Dv_{50}=3.7{\pm}0.2{\mu}m$) DSF were prepared by conventional milling and sifting, followed by jet milling at 7 bars. Hamburger patties containing 5% of each DSF were prepared for a property analysis. The hamburger patties made with 5% superfine DSF showed the lowest cooking loss among the treatment groups (p<0.05). The patties with superfine DSF also retained the texture profile values of the control patties in terms of hardness, gumminess, springiness, and chewiness, while the addition of coarse and fine DSF increased the hardness and chewiness significantly (p<0.05). The sensorial results of quantitative descriptive analysis (QDA) indicate that the patties containing superfine DSF were softer and tenderer than the controls (p<0.05). Although the overall acceptability of the patties made with coarse and fine DSF was poor, the overall acceptability of the superfine DSF patty was the same as that of the control patty. These results suggest that superfine DSF is an excellent food material that can supply dietary fiber, while maintaining the physical characteristics and texture of hamburger patty.
Lactic acid bacteria were isolated from piglets and chicken and characterized. Lactic acid bacteria showing resistance to low pH and bile, adhesion to intestinal epithelium cells, and the inhibition of Escherichia coli and Salmonella spp. were identified as Lactobacillus acidophilus. L. acidophilus PF01 survived for 2 h in MRS broth adjusted to pH 2. L. acidophilus CF07 was less resistant than L. acidophilus PF01 to pH 2, but survived at pH 2.5 for 2 h. Both of isolates were able to grow in MRS broth containing 0.3% (w/v) bile, with L. acidophilus CF07 being more tolerant to bile than L. acidophilus PF01. L. acidophilus PF01 and CF07 adhered specifically to the duodenal and jejunal epithelium cells of piglet, and the cecal and duodenal epithelium cells of chicken, respectively. Both of isolates did not adhere to the epithelium cells of the various animal intestines from which they were isolated. When L. acidophilus was cultured with E. coli and Salmonella spp. in MRS broth, MRS broth containing 2% skim milk powder or modified tryptic soy broth at $37^{\circ}C$, L. acidophilus PF01 and CF07 inhibited the growths of E. coli K88 and K99, and S. enteritidis and S. typhimurium, respectively. Both of isolates were found to possess the essential characteristics of probiotic lactic acid bacteria for piglet and chicken.

Catechin products in green tea extract was prepared to investigate antibacterial activity on the pathogenic bacteria. Survival of pathogenic bacteria (MASA - methicillin resistant Staphylocouus aureus, E.coli O157 and S. typhimurium Sal-13) in tryptic soy agar(TSA) containing Catechin products powder incubated at various concentration was evaluated. TSA containing $0{\sim}2%(w/v)$ of Catechin products was inoculated approximately $10^4\;CFU/ml$ of pathogenic bacteria and incubated at $37^{\circ}C$ for 24 hours. The plate counting technique and clear zoon test were used to test survival effect of the Catechin products. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) was derived from the survival curves of pathogenic bacteria. S. typhimurium Sal-13 was the most sensitive strain to Catechin products. This result suggested that Catechin products can be used as an effective natural antibacterial agent.

Tocopherol and tocotrienol contents of commonly consumed foods in Korea were determined by saponification or direct solvent extraction followed by normal phase liquid chromatography. All samples were locally obtained in the year of 2002 and 2003. The study included 13 meats, 15 fishes and shellfishes, 4 seaweeds, 7 mushrooms, 19 milk and milk products, 6 legumes, 12 nuts, 17 processed foods and 17 Korean traditional foods. All of the vitamin E isomers were quantitated and the results were expressed as $\alpha-tocopherol$ equivalent $(\alpha-TE)$. The relatively higher amount of vitamin E was found in beef boiled in soy, dried squid, toasted seaweed, milk powder, soritae, sunflower seeds, ramyon (instant noodle), and kochujang from meats, fishes, seaweeds, milk products, legumes, processed foods, and traditional foods, respectively. This study provided reliable vitamin E data in commonly consumed foods in Korea for the nutritional information and food composition database.

In other to investigate the hypolipidemic effect of dry edible leaves on serum lipids, four kinds of powdered leaves(persimmom, mulberry, perilla, and soy bean) were added to experimental diets at the levels of 5%(w/w). The diets were fed to 30 male Sprague-Dawley rats, aged 4 weeks and weighing 60$\pm$5g, for 3 weeks. Food intake was the largest in Group 1(control), with 5% of cellulose powder, while food efficiency was the highest in Group 2(persimmon). Total cholesterol level in serum was lower in Group 5(soybean) and Group 4(perilla) than the other groups. In comparison with Group 1, HDL-cholesterol level was very high in Group 4 and atherogenic index was low in Groups 4 and 5. Free cholesterol level was the highest in Group 2, and was the lowest in Group 1. Both LDL and LDL-cholesterol levels were the lowest in Group 1, while they were very high in Groups 2 and 3(mulberry). Triglyceride level was the lowest in Group 4, and the highest in Group 1. Except Group 3, all groups had lower phospholipid level than Group 1. Compared with Group 1, calcium level in serum was low in Groups 3, 4 and 5, magenesium level was low in Groups 2, 3 and 5, phosphate level was high in Group 4, and iron level was exceptionally low in Groups 4 and 5. In conclusion, Group 4(perilla) and Group 5 (soybean) showed a favorable effect in atherogenic index and serum levels of various lipids.
The study was set for one year to measure the effects of concentrate supplementation on reproductive performances and semen quality in indigenous rams. The study was conducted at the Department of Surgery and Obstetrics, Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh, Bangladesh during the period from May 2011 to April 2012. Forteen ram lambs (4~5 months) were randomly divided into two equal groups (n=7); supplemented vs control. The animals of control group were maintained on natural grazing. Along with natural grazing the supplemented group was on supplemented feeding. The concentrate supplementation (Wheat bran, Crushed maize, Soy bean meal, Fish meal, DCP powder, Vitamin mineral premix, Salt) was provided @ 300 g/head /day to the supplemented group. Body weight, scrotal circumference, BCS and libido index were measured weekly. Age, body weight and scrotal circumference at puberty were recorded. Semen was collected once in a weak using artificial vagina and chilled at $5^{\circ}C$ for 48h for evaluation. Concentrate supplementation did not influence (p>0.05) body condition score, age, weight, scrotal circumference at puberty and libido index. Final body weight (kg), growth rate (g/d), scrotal circumference (cm) and scrotal growth rate (mm/15d) were significantly (p<0.05) higher in supplemented group of rams compared to control. Volume, concentration, motility and membrane potentiality of spermatozoa were varied significantly (p<0.05) in supplemented and control groups. However, density, mass motility, viability and sperm with normal acrosome, midpiece and tail were not differed insignificantly (p>0.05) in different observation times. It was concluded that concentrate supplementation with free grazing improved weight and scrotal circumference gain and semen production with increased quality in indigenous ram.
The purpose of this study is to survey various recips of the roasted skewered beef (Sanjuk) with twenty three classical cookbooks written before 1943 in Korea. The recipes of the roasted skewered beef are found thirty times in the records, which can be classified into six groups such as the palm-type skewered beef (Sulhamyukjuk), little finger-type skewered beef, mixed skewered beef, juice skewered beef, little finger-type skewered internal organs, and wide-cut skewered internal organs. The palm-type skewered beef and the mixed skewered beef most frequently appeared in the records. The 'Sulhamyukjuk' in the 17th century were inherited while changing its name to 'Sanjuk' in the late 18th century, which is the origin of 'Bulkoki'. There were two types of the roasted skewered beef, the palm-type and the little finger-type; and the palm type preceded the little finger-type. They were used with no change until the 19th century. Actually the roasted skewered beef existed even in the 16th century, but were put down in the early 17th century. In the cooking of 'Sulhamyukjuk' the process of dipping shortly into cold water in the midst of roast seems to absolutely disappeared. Some recipes of the roasted skewered beef were lost, but most have been inherited in the similar way with simplification including little use of internal organs. The main ingredients consisted of parts of cattle such as fresh meat, intestines, heart, liver, omasum, tripe, head, sweet bread, and lung with various vegetables and mushroom. And the main seasonings were mixtures of oil, soy sauce, sesame seed powder, scallion stalk, pepper, sesame seed oil, and salt. And sometimes wine, vinegar, ginger, garlic, and sugar were added.

Background: This research main objective was to evaluate a proliposomes (PLs) formulation for the enhancement of oral bioavailability of ginsenosides, using ginsenoside Rg3 (Rg3) as a marker. Methods: A novel PLs formulation was prepared using a modified evaporation-on-matrix method. Soy phosphatidylcholine, Rg3-enriched extract, poloxamer 188 (Lutrol® F 68) and sorbitol were mixed and dissolved using a aqueous ethanolic solution, followed by the removal of ethanol and lyophilization. The characterization of Rg3-PLs formulations was performed by powder X-ray diffractometry (PXRD), transmission electron microscopy (TEM) and in vitro release. The enhancement of oral bioavailability was investigated and analyzed by noncompartmental parameters after oral administration of the formulations. Results: PXRD of Rg3-PLs indicated that Rg3 was transformed from crystalline into its amorphous form during the preparation process. The Rg3-encapsulated liposomes with vesicular-shaped morphology were generated after the reconstitution by gentle hand-shaking in water; they had a mean diameter of approximately 350 nm, a negative zeta potential (- 28.6 mV) and a high entrapment efficiency (97.3%). The results of the in vitro release study exhibited that significantly more amount of Rg3 was released from the PLs formulation in comparison with that from the suspension of Rg3-enriched extract (control group). The pharmacokinetic parameters after oral administration of PLs formulation in rats showed an approximately 11.8-fold increase in the bioavailability of Rg3, compared to that of the control group. Conclusion: The developed PLs formulation could be a favorable delivery system to improve the oral bioavailability of ginsenosides, including Rg3.
Two experiments, involving a total of 100 crossbred pigs (Hampshire$\times$Landrace$\times$Duroc) aged 5 weeks, were used to evaluate the effect of Roselle (Hibicus sabdariffa Linn.) calyx as an antioxidant and acidifier on growth performance. Experiment 1: growth performance response of pigs fed basal corn-soy diet was compared with that of pigs consuming diets that contained 4, 8 and 12% Roselle in powder form, 4 g/kg acidifier (Fra$^{(R)}$Acid Dry) or 100 mg/kg antibiotic (Aurofac$^{(R)}$). All diets were isocaloric and isonitrogenous. Twenty-four castrated male and twelve female pigs were randomly allocated into 6 treatments which comprised 3 replicates (2 male and 1 female) of 2 pigs each. The results demonstrated no beneficial weight gain and feed intake response among treatments at 7, 9 and 11 weeks of age (p>0.05). However, feed-to-gain ratios (FCR) of Roselle-fed groups were significantly different from the basal-diet group at 7 weeks of age (p<0.05). Pigs fed with 8% Roselle had the lowest FCR. Therefore, 8% was set as an appropriate level of Roselle in feed. Experiment 2 was conducted to determine antioxidant and acidifier properties. Pigs were fed similar diets to Experiment 1 except that Roselle was fed to only one treatment at the level of 8%. Sixty-four piglets, 32 castrated male and female each were randomly allocated into 4 treatments which comprised 4 replicates (2 male and 2 female) of 4 pigs each. Body weight was measured. At 7 and 9 weeks of age, four pigs from each treatment were randomly selected. The pH in their gastrointestinal tract, pepsin activity in stomach mucosa, trypsin activity in the pancreas and protein and fat digestibility in the ileum were measured to investigate acidifier properties. For antioxidant properties, malondialdehyde (MDA) and glutathione concentration in plasma and liver were used as parameters. The results showed no significant difference in weight gain, pH or pepsin activity among all treatments at both ages (p>0.05). Nevertheless, trypsin activity and fat digestibility of the Roselle-fed group were higher than the basal-diet group at 7 weeks of age (p<0.05). Glutathione in plasma was significantly different between antibiotic-fed and basal-diet groups (p<0.05). Significant differences were found only in some parameters and between the basal-diet group and the other groups. Therefore, it cannot be precisely concluded that Roselle in powder form has clear acidifier and antioxidant properties in postweaning pigs. Further studies should be undertaken to clearly confirm both properties.
This study was reviewed the changes in main ingredients, seasonings and cooking methods of Tangpyeongchae in Korean cook books and literatures published from the 1700s to the 1960s. The first published books about Tangpyeongchae were in Kosasibijib and Kyongdojabji, written in 1783 and the late 1700s, respectively. Tangpyeongchae, a representative traditional Korean dish that was royal cuisine offered at ritual events in the Chosun Dynasty, was called Cheongpochae in the royal court. It was a dish made by mixing cheongpomuk (mung bean gel), meat, dropwort, mung bean sprout, egg strips and laver. This dish has been seasoned with vinegar, soy sauce, black pepper, garlic, green onion, red pepper, salt, sugar, sesame oil and sesame salt since the early 1900s. Dropwort, egg strips, laver, pine nut (powder), red pepper powder, and red pepper threads were used as garnishes. Tangpyeongchae was made by mixing cheongpomuk with other ingredients and seasonings until the late 1800s. Since the early 1900s Tangpyeongchae has been seasoned first with other ingredients and then mixed cheongpomuk.
