  • This study optimized the mixing ratios of seafood sauce with blue crab for maximal sensory attributes using a response surface methodology with central composite design. It evaluated sensory appeal, nutritional value, and some rheological properties. The optimal formulation appeared to be 252 g of tomato paste, 78 g of chopped garlic, and 519 g of blue crab block; this ratio resulted in a predicted sensory score of 5.7 (on a 7-point scale) for overall acceptability. Addition of blue crab block increased moisture, ash, and protein contents in various sauces, but fat contents were similar in every sauce. Major free amino acids such as glutamic acid, phospho serine, asparagine, and arginine composed about $60\%$ of the total amino acid content. Standard and optimized sauces were red and light yellow, and those color values were significantly higher than in American-style sauces. Optimal viscosity was half the value of American-style sauces; more blue crab block added to the sauce resulted in lower viscosity. Adding this sauce to seafood dishes will likely aid development of flavoring substances.

  • Anthranilate derivatives have been used as flavoring and fragrant agents for a long time. Recently, these compounds are gaining attention due to new biological functions including antinociceptive and analgesic activities. Three anthranilate derivatives, N-methylanthranilate, methyl anthranilate, and methyl N-methylanthranilate were synthesized using metabolically engineered stains of Escherichia coli. NMT encoding N-methyltransferase from Ruta graveolens, AMAT encoding anthraniloyl-coenzyme A (CoA):methanol acyltransferase from Vitis labrusca, and pqsA encoding anthranilate coenzyme A ligase from Pseudomonas aeruginosa were cloned and E. coli strains harboring these genes were used to synthesize the three desired compounds. E. coli mutants (metJ, trpD, tyrR mutants), which provide more anthranilate and/or S-adenosyl methionine, were used to increase the production of the synthesized compounds. MS/MS analysis was used to determine the structure of the products. Approximately, $185.3{\mu}M$ N-methylanthranilate and $95.2{\mu}M$ methyl N-methylanthranilate were synthesized. This is the first report about the synthesis of anthranilate derivatives in E. coli.

  • Curcumin is a widely used flavoring agent in food, and it has been reported to inhibit cell growth, to induce apoptosis, and to have antitumor activity in many cancers. Cisplatin is one of the most potent known anticancer agents and shows significant clinical activity against a variety of solid tumors. This study was undertaken to investigate the synergistic apoptotic effects of co-treatment with curcumin and cisplatin on human tongue SCC25 cells. To investigate whether the co-treatment efficiently reduced the viability of the SCC25 cells compared with the two treatments separately, an MTT assay was conducted. The induction and the augmentation of apoptosis were confirmed by DNA electrophoresis, Hoechst staining, and an analysis of DNA hypoploidy. Western blot, MMP and immunofluorescence tests were also performed to evaluate the expression levels and the translocation of apoptosis-related proteins following the co-treatment. In this study, following the co-treatment with curcumin and cisplatin, the SCC25 cells showed several forms of apoptotic manifestation, such as nuclear condensation, DNA fragmentation, reduction of MMP, increased levels of Bax, decreased levels of Bcl-2, and decreased DNA content. In addition, they showed a release of cytochrome c into the cytosol, translocation of AIF and DFF40 (CAD) to the nuclei, and activation of caspase-7, caspase-3, PARP, and DFF45 (ICAD). In contrast, separate treatments of $5{\mu}M$ of curcumin or $4{\mu}g/ml$ of cisplatin, for 24 hours, did not induce apoptosis. Therefore, our data suggest that combination therapy with curcumin and cisplatin could be considered as a novel therapeutic strategy for human oral squamous cell carcinoma.

  • Knowledge and attitudes on current selection of fats and oils were surveyed among college students and USDA extension off campus faculties. The objective of this survey was to obtain information about the nutrition knowledge and attitudes toward fats and to assess relationships between the nutrition knowledge, general attitudes toward dietary fats, and specific attitudes toward the eating of certain foods. The attitudes toward and nutrition knowledge of dietary fat sections consisted of 22 and 39 statements respectively. Avoiding red meat and eggs and avoiding fats as a flavoring were attitudes whose maintenance may require special, long-term intervention strategies. Replacing high-fat foods with low-fat foods, modification(cutting fat off any meat) and substitution were easily adopted and maintained low-fat habit. The responses to wanting to lose some weight and feeling better if increasing exercise were favorable. The attitudes toward the possible relationships between fat consumption and health were favorable. Respondents on the nutrition knowledge test attained a mean score of 129.69 and a median score of 127 our of the highest possible score of 200. Extension off campus faculties, nutrition majoring/majored subjects, and over 41-year-olds tended to have more favorable general attitudes and specific attitudes toward the consumption of certain foods and higher knowledge. Senior students had more negative general attitudes and specific attitudes, and college graduates and graduate students had more nutrition knowledge. Nutrition know-ledge was related to general attitudes toward dietary fats, but not to more specific attitudes toward the eating of certain foods. Nutrition education will not be effective in modifying the intake of dietary fats in the population because nutrition knowledge related to general attitudes toward dietary fats and general nutrition practice but not the eating of certain foods.

  • Diallyl sulfide (DAS), a flavoring compound derived from garlic, is considered to have cancer chemopreventive potential in experimental animals and humans. This study was designated to examine possible chemopreventive effects of DAS on colon carcinogenesis using genetically engineered transgenic $Apc^{Min/+}$ mice, a well-established animal model for familial adenomatous polyposis (FAP) and sporadic colorectal cancer. Male C57BL/6J-$Apc^{Min/+}$ mice were divided into three groups. Animals of group 1 were placed on the basal diet (AIN-76A) as non-treated controls. Animals of groups 2 and 3 were given DAS-containing diets (in doses of 100 and 300 ppm, respectively). All mice were sacrificed at the end of week 10 of the experiment. Histopathological investigation revealed that the incidence of colonic polyps was decreased dose-dependently by 19% (13/16) in group 2 and by 32% (13/20) in group 3 compared to the 100% incidence (10/10) in group 1. The multiplicity of colonic polyps per mouse was also slightly decreased by DAS treatment ($1.88{\pm}0.35$ in group 2 and $1.63{\pm}0.36$ in group 3) compared to $2.00{\pm}0.39$ in group 1. On the other hand, there were no significant differences in the numbers of total polyps per mouse in the small intestine between the groups. Taken together, we suggest that DAS may exert promising inhibitory effects on colon carcinogenesis in the transgenic $Apc^{Min/+}$ mice.

  • Sesame has been consumed for centuries as flavoring ingredient in eastern Asian countries, especially Korea. Sesame seeds have been used as health food for traditional medicine to prevent disease in Asian countries for several thousand years. Sesame seed has higher oil content (around 50%) than most of the known oilseeds. Sesame oil is rich in monounsaturated and polyunsaturated fatty acids. Extraction of sesame has developed significantly over the years. The mechanical method was an early means of separation which was physical pressure to squeeze the oil out. Nowadays, solvent extraction becomes the commonly used commercial technique to recover oil from oilseeds. In this study, we investigated extraction efficiency and quality of oil affected by cultivars and extraction methods of sesame seed. Different variables were investigated; roasting temperature ($170{\sim}220^{\circ}C$), extraction methods (solvent and physical pressure), forced ventilation system and cultivars. The Contents of B(a)P in sesame oil after roasting at $170{\sim}220^{\circ}C$ were 0.30~2.53 ppm. When we introduced forced ventilation system during roasting, B(a)P Contents were decreased up to 36%. The Oil extraction efficiency on sesame seed was statistically depending on the cultivars and extraction methods. The oil extraction yields of solvent and physical pressure extraction were 56.3% and 44.6%, respectively. Many of sesame cultivars and genetic resources are linolenic acid content of less than 0.5%. The results supported that we have developed a safe and high quality sesame oil processing methods for small and medium-sized companies.

  • Conditions for processing dried condiments with powdered sea tangle were investigated. The most appropriate method for sea tangle extraction was two-stage extraction, that extracted with addition of 70% ethyl alcohol at $25^{\circ}C$ for 1 hour and residue was re-extracted with water(1:15, w/w) at 7$0^{\circ}C$ for 3 hours. The yield of soluble solids under above-mentioned conditions was 14.9%. As a result of omission tests, free amino acids were predominated in the taste compounds of sea tangle extracts rather than nucleotides, and the contribution of free amino acids and nucleotides to the taste of sea tangle extracts was remarkable. The major flavoring components of sea tangle extracts were matters of low molecular weight such as free amino acids and oligopeptides below 5,700 dalton. Contents of carbohydrate, total nitrogen and amino nitrogen in dried condiments prepared with sea tangle extracts were 64.9%, 3.7% and 2.1%, respectively. And drying yield, solubility and absorption rates at Aw 0.88 were 14.7%, 98.3% and 8.4%, respectively.
