Previously, we reported that a diet including sesame meal (SM) increased plasma total and high-density lipoprotein (HDL)-cholesterol concentrations in goats. In the present study, the components in the sesame meal that can increase plasma total and HDL-cholesterol concentrations have been examined. In experiment 1, we gave goats defatted sesame meal diet (DSM) to investigate the influence of ether extract fraction remained in sesame meal. Corn gluten meal diet (CGM) was also fed to goats as a high-protein diet to examine the influence of high dietary protein level caused by usage of sesame meal. Plasma total and HDL-cholesterol concentrations of goats fed DSM and CGM did not change during experimental periods though they were elevated by feeding SM. In experiment 2, the influence of sesame oil and corn oil added in diets on plasma total and HDL-cholesterol concentrations in goats was investigated. Plasma total and HDL-cholesterol concentrations were increased by feeding both corn oil diet and sesame oil diet. In conclusion, the increase in plasma HDL-cholesterol concentration by feeding sesame meal was resulted by the effect of ether extract fraction including sesame oil or some lipid-soluble components remained in sesame meal.

Two experiments were conducted to determine ileal digestibilities for the amino acids contained in sesame meal using the regression technique and then applying the values obtained in a growth trial using growing-finishing pigs. For the digestibility trial, four, 20 kg crossbred (Yorkshire $\times$ Landrace $\times$ Beijing Black) barrows were fitted with a simple T-cannula in the terminal ileum. After recovery, the barrows were fed one of four experimental diets according to a $4{\times}4$ Latin Square design. The pigs were fed corn-soybean meal based diets supplemented with 0, 25, 50 or 75 percent sesame meal. For the growth trial, 210 crossbred (Yorkshire $\times$ Landrace $\times$ Henan Min) growing pigs ($21.8{\pm}1.4kg$), were fed corn-soybean meal based diets supplemented with 0, 3, 6, 9, or 12% sesame meal. Three pens (7 gilts and 7 castrates) were assigned to each treatment. With the exception of arginine and phenylalanine, the digestibility coefficients for the indispensible amino acids declined as the level of sesame meal in the diet increased. There was little agreement between the amino acid digestibilities determined with the regression technique and values previously published for sesame meal determined with the direct method. Daily gain and feed conversion both declined (linear effect p=0.02 and 0.06 respectively) as the level of sesame meal in the diet increased.

Biodegradable films were prepared from roasted sesame meal and rice bran. Acetic anhydride, succinic anhydride, and formaldehyde were added to the film-forming solutions, and their effects on tensile strength, percent elongation, water vapor permeability, and water solubility of the films were studied. Roasted sesame meal did not form film without acylation or addition of formaldehyde. Acylated roasted sesame films had higher tensile strength and water-solubility, and lower % elongation than rice bran films. Acylation with acetic and succinic anhydrides increased tensile strength, percent elongation, and water solubility of rice bran films, but decreased water vapor permeability. Treatment with formaldehyde increased tensile strength of roasted sesame and rice bran films and % elongation of rice bran films, while reducing water-solubility of roasted sesame and rice bran films and water vapor permeability of rice bran films.

Influence of dietary sesame meal on plasma glucose, non-esterified fatty acid (NEFA), triglyceride, total cholesterol, high-density lipoprotein (HDL)-cholesterol and urea concentrations in goats was examined. Goats were fed a control diet (50% timothy hay and 50% concentrates) (CD) or a sesame meal diet (50% timothy hay, 25% concentrates and 25% sesame meal) (SMD) during 12 days. Blood samples were taken after overnight fasting and afternoon every day. Body weight was not changed by feeding either CD or SMD. The concentrations of plasma triglyceride and urea were higher (p<0.05) in goats fed SMD than those fed CD. Plasma NEFA concentration was higher in plasma samples after overnight fasting. Plasma glucose concentration in plasma samples collected afternoon was higher than those after overnight fasting. Plasma total cholesterol concentration was significantly increased by feeding SMD but not by feeding CD, which was due to the remarkable increase of plasma HDL-cholesterol concentration. In conclusion, dietary sesame meal brought about an increase in plasma total cholesterol concentration accompanied with an increment in plasma HDL-cholesterol consentration in goats.

The purpose of this study was to measure and investigate the acute effects of two fatty meals (high-SFA & high-PUFA) on post-prandial thermic effect, substrate oxidation, and satiety. Eight healthy adults (four males and four females) aged 19-22 years were assigned to consume two isocaloric meals: high in saturated fatty acids from butter and high in polyunsaturated fatty acids from sesame oil. Indirect calorimetry was used to measure resting energy expenditure (REE), post-prandial energy expenditure for five hours, and substrate oxidation. Satiety of the subjects after meals was estimated by using visual analogue scales (VAS). Five hours thermic effect of food (TEF) was not significantly different between butter meal (6.5% of energy intake) and sesame oil meal (7.3% of energy intake), but, the TEF of butter meal reached the peak point at 150 min and decreased more rapidly arriving to REE in 270 min. On the other hand, TEF of sesame oil meal reached the peak at 90 min and decreased slower than butter meal (still higher than REE at 300 min). No significant differences in substrate oxidation rates were found between the two meals. Post-prandial fat oxidation rates increased significantly after the consumption of both butter and sesame oil meal than that of the pre-prandial state. Satiety values (hunger, fullness, and appetite) were similar among the meals, but recovery of hunger and fullness to the pre-prandial state was faster in butter meal than that of the sesame oil meal.

White and black sesame produced in Korea were defatted with ethyl ether or n-hexane. Defatted sesame meal was extracted with water and salt solution, and protein extraction was precipitated at various pH 1 through 12, with trichloro acetic acid (TCA), tannic acid and ammonium sulfate, respectively. Protein was purified by Sephadex A-25, G-75, G-100 and G-200, and identified its protein fraction by polyacrylamide gel electrophoresis. Amino acids composition of protein in white sesame was analyzed by automatic amino acid analyzer. Protein contents of white sesame, black sesame and sesame meal are 20.5%, 19.2%, and 44.7%, respectively. n-Hexane was the most suitable solvent for extraction of oil from sesame. Crude protein precipitation was better in higher pH. The protein extraction was more effective with the solution containing sodium chloride tinder the pH 8. Globulin in total protein was high and prolamin was less than in other cereal proteins. Glutamic acid contents of white sesame and sesame globulin were 17.1%, and 20%, respectively. Both proteins contained relatively high levels of essential amino acids. 12-13 bands were found in water soluble protein and 2 bands in salt soluble protein were detected by the disc gel electrophoresis, and were identified in both of white and black sesame. The salt soluble protein of white sesame could be purified by Sephadee G-100 and G-200.

This study aimed to investigate the physicochemical characteristics of fish meal, bone meal, and sesame oil cake, which are readily available by-products from agriculture and fisheries, during the process of liquid fertilizer fermentation, and to examine the effects of liquid fertilizer application on seed germination and growth of tomatoes. During processing the fermentation for liquid fertilizers by using fish meal, bone meal, and sesame oil cake liquid fertilizers, the pH of the fertilizer increased in the order of bone meal > fish meal > sesame oil cake, and the concentration increased rapidly up to 30 days in all types of liquid fertilizer. The nitrogen content of the liquid fertilizers increased as fermentation progressed in the order of fish meal > bone meal > sesame oil cake. The phosphorus content increased as fermentation progressed and the highest was 1.0 % in the liquid fertilizer of sesame oil cake. The germination rate and its index of radish seeds were compared for different dilutions of each of the liquid fertilizers. Excluding the 10-fold dilution of the fish meal and oil cake liquid fertilizer, all the treatment groups showed a germination rate ≥ 95 % and the germination index tended to increase with dilution rate of liquid fertilizers. For responses of tomato growth, there were no significant differences among the liquid fertilizer treatment groups; however, the organic content, microbial density, and microbial biomass C in the soil were higher than chemical fertilizer treatment. These results demonstrated that there were differences in the characteristics of liquid fertilizers depending on the materials used, and that liquid fertilizer can be used for nutrition management for the organic crop cultivation.

To extract insoluble proteins of sesame meal residue by using microorganism, the sesame meal residue was treated with crude enzyme solution from Bacillus sp. CW-1121. It was found that the solubility reached to maximum at pH 7.5, $45^{\circ}C$. Under optimum condition, the nitrogen solubility with the enzyme solution from Bacillus sp. CW-1121 reached to 60% in 2 hours. Nitrogen solubility of protein from sesame meal showed minimum value at pH 4.5 and significantly increased above pH 6.0. When the protein from sesame meal extracted with Bacillus sp. CW-1121 was subjected to sodium dodecyl sulfate polyacrylamide gel electrophoresis, water soluble protein was showed 4 bands and salt soluble protein was showed 2 bands. The amino acid composition of water soluble protein, salt soluble protein and free amino acid indicated relatively high contents of serine (17.24 mg/g), glutamic acid (10.77 mg/g) and glutamic acid (6.55 mg/g). Specially, the contents of essential amino acids were high.
