  • Capsaicin, a pungent ingredient in chili pepper, is known to excite sensory neurons that mediate pain sensation. This effect of capsaicin is determined by unique receptors and the capsaicin receptor (transient receptor potential subfamily V, member 1 (TRPV1)) was cloned recently. TRPV1 contains six transmembrane domains and three ankyrin repeats at N-terminal. This characteristic architecture is common in other ion channel in TRPV families. (omitted)

  • This study was performed to compare the contents of nutrients and taste components in Korean(King and Dabok) and imported(from Myanma) red pepper powders. Red pepper imported from Myanma was narrower and lighter and showed significantly higher contents of moisture and lipid. Lower amount of fructose and glucose shown in imported red pepper powder seemed related to lower sensory score in sweet taste. Capsaicin was contained much higher in imported red pepper powder and looked related to higher score in pungent tastes. Organic acids like oxalic acid, malonic acid, succinic acid, pyroglutamic acid were significantly lower in imported red pepper powder. Imported red pepper powder showed lower amount of $\beta$-carotene, capsanthin and color value(L, a, b) than Dabok and obtained lower sensory score in color.

  • This treatise deals mainly with the culinary cultures of garlics, a very important condiment in Korea and France. Classified specifically as a condiment in the category of spices, garlic(A. sativum L.) is typically used to season a wide variety of foods, to give the dishes to add a pungent and pleasant flavor, highly characteristic of the delicate seasoning styles of Korean and French cuisine. Garlic is also known to be used as an invigorant. used for medicinal and mystical purposes. In both Korea and France. garlic is used in fresh state, sliced, diced, or crushed. Some examples of traditional Korean dishes using garlic is Tongmaneul Jangachi(garlic in a whole bulb, seasoned in soy sauce), alcoholic liquor of garlic, and red pepper paste with garlic. French cuisine includes garlic in sauces such as Aillade, Vinairette a l'alil, Sauce Pailloti, and in a variety of salads and Cruton, mixed with the local vegetables of every province of the country.

  • The clastogenic activity of capsaicin, a major pungent and irritating constituent of hot chili pepper, was evaluated in cultured human lymphocytes. Capsaicin (125, 250, and 500 $\mu$M) caused cytogenetic damage as determined by increased frequency of chromosome/chromatid aberrations compared to the solvent control. The mitotic indices were also decreased in a concentration-related manner in capsaicin-treated cells. Moreover, capsaicin suppressed [$^3$]thymidine incorporation into lymphocytes. The clastogenicity and cytotoxicity of capsaicin towards human lymphocytes were evident without an external metabolic activation system. Taken together, these findings suggest that capsaicin is a genotoxic agent and may thus represent a potential health hazard in humans.

  • This study was a survey of the taste for color arrangement and the relation to taste with food color. The term of investigation and object was the same as before mentions. The data-treatment was determinded by frequence percentage chi-square and F-test as measured by SAS program for PC and statistical figures were obtained by GDAS. The results were as follows;1. In the taste of arrangement for food, color. The most frequent colors were green and white followed by a yellowish green red. In preference 50's object was difference from another aged. It's significance was showed orange yellow pink and white. 2. In the relation of food color and taste term the color shown a pungent sweet hot and delicious taste was red and a sour astringent sweet taste was orange and anastringent bitter delicate hard taste was brown and a proteiny sofe sweet delicate taste was yellow and a cool taste was yellow and a cool taste was green, and a cool, bitter taste was blue and an astrngent taste was pink, and a bitter hard, tasteeless taste was black and a proteiny sofe taste was white. But in the case of any a bitter taste it's significance was shown.

  • Polysiphonia pacifica is rhodomelaceous red algal species that includes five varieties in Pacific Ocean: P. pacifica var. delicatula, P. pacifica var. distans, P. pacifica var. determinata, P. pacifica var. disticha, and P. pacifica var. gracilis. We here report morphology and phylogeny of P. pacifica to confirm the relationships among previously described varieties as a loan of type specimens from US and to assess phylogenetic relationships of closely related species using plastid protein-coding rbcL gene. Polysiphonia pacifica is distinguished by having creeping filaments attached by unicellular rhizoids not cut off by cross walls, four pericentral cells, ecorticate, trichoblasts rare, ultimate branchlets attenuate at the tip but not pungent, and tetrasporangia in long straight series in the ultimate branchlets. The protein-coding plastid rbcL gene sequence data show that P. pacifica is distinctly different from the superficially similar species, P. morrowii and P. stricta. However, the rbcL sequences of P. pacifica var. pacifica and var. disticha are identical though they have morphological variation.

  • Red pepper powders with variuos seed contents (0%, 10%, 20%) and particle sizes were stored at 0$^{\circ}C$, 20$^{\circ}C$, and 30$^{\circ}C$ for 90 days, and the changes in their characteristics were monitored. The initial moisture content was about 13%, and the powders were packed in 0.1 mm-thick polypropylene (PP) bags. Moisture content of each power remained constantly, so PP bags appeared to be effective to prevent moisture transmission. All the values of L*, a* and b* were higher in fine particles than in coarse particles. Storage at 0$^{\circ}C$ did not change any color values, however, overall color values devreased apparently when stored at 30$^{\circ}C$ for 90 days. Capsanthin contents decreased gradually at all storage temperatures and more rapidly at higher temperature. The contents of capsaicinoids in fine particles (49∼59 mg%) were twic as much as those in coarse particles (15∼36 mg%), and they did not change throughout the storage.

  • Capsaicin, a major pungent ingredient in red hot pepper, has long been used in food additives and drugs. We have previously reported that capsaicin induces apoptosis in Korean stomach cancer cell line, SNU-1. In the present study, the mechanism of capsaicin-induced apoptotic cell death was investigated in SNU-1. Treatment of capsaicin to SNU-1 produced dose-dependent increase of apoptotic cell death and [Ca2+]$_{i}$ concentrations.(omitted)d)
