In order to extend the shelf life of Wasabi paste, the effects of citric acid were confirmed at $35^{\circ}C$ for 28 days. Citric acid-treated groups contained citric acid in amounts of 0.05, 0.10, 0.17, 0.30, and 0.40%, respectively. Quality characteristics of Wasabi pastes were determined in pH, titratable acidity, soluble solid content, color values, microbial analysis (aerobic bacteria, yeast), gas production, and content of allyl isothiocyanate. The pH and titratable acidities of Wasabi pastes added with citric acid were indicated as 4.03-5.19 and 4.23-4.82%, respectively. Soluble solid content was significantly different according to concentrations of citric acid. L values showed the highest at $50.05{\pm}0.46$. a and b values were increased during the storage period. Total aerobic bacteria and yeast counts of Wasabi pastes were decreased in a dose-dependent manner. Gas production from Wasabi pastes showed at 19.55-19.80 mL/tube after 28 days of storage. The addition of citric acid (0.3% or more) to the Wasabi paste resulted in increased storage stability.

To compare the quality characteristics of commercial wasabi paste products, the physicochemical and microbial characteristics of 6 samples were analyzed. In addition, the contents of allyl isothiocyanate, which show unique flavor and antimicrobial activity in wasabi paste products, were compared. pH of commercial 6 wasabi products were ranged from $4.12{\pm}0.01$ to $4.90{\pm}0.01$, and titratable acidities of products distributed at cold temperature (CW) were higher $0.60{\pm}0.00{\sim}0.77{\pm}0.02%$ than those of products distributed at room temperature (RW). Salinities of RW were higher ($4.27{\pm}0.06{\sim}7.53{\pm}0.12%$) than those of CW ($2.20{\pm}0.00{\sim}3.60{\pm}0.10%$). Soluble solid and sorbitol contents of RW were higher ($33.00{\pm}1.00{\sim}44.67{\pm}2.08^{\circ}Brix$, $378.90{\pm}63.79{\sim}724.37{\pm}7.85mg%$) than those of CW ($22.00{\pm}1.73{\sim}27.00{\pm}1.00^{\circ}Brix$, $27.67{\pm}9.92{\sim}175.31{\pm}10.56mg%$), respectively. The viable cell counts of samples were $ND{\sim}3.65{\pm}0.23 log\;CFU/g$ without distribution method and packaging type, and yeasts and molds were not detected in 6 wasabi products. Allyl isothiocyanate contents of RW were higher ($53.35{\pm}0.08{\sim}159.76{\pm}0.81mg%$) than those of CW ($24.07{\pm}7.69{\sim}48.19{\pm}0.15mg%$).

The Albuginales (Oomycetes) consist of obligate biotrophic pathogens, none of which is culturable on artificial media. This group causes white blister rust disease in diverse angiosperm plants, including many economically important crops such as sunflower, horseradish, rape, radish, spinach, and wasabi. Recent advances in molecular phylogenetic tools and findings of new morphological characters have advanced our knowledge on their diversity, evolution, and systematics. This review introduces the white blister rusts and discusses recent innovations resulting from studies on Albuginales.

Occurrence of soft rots was observed on wasabi (Wasabia japonica Matsum) grown in Chuncheon and Pyengchang Kangwon province, Korea. The symptoms appeared on the wasabi root, which became mushy and black. This eventually resulted in wilting and death of the aboveground parts of the wasabi. The causal organism was isolated from the infected lesions and was identified as Erwinia carotovora subsp. carotovora based on the morphological, physiological and biochemical characteristics, and on the results of the Biolog program (Biolog Inc., U. S. A.). E. carotovora subsp. carotovora is the first described bacterium which causes bacterial soft rot on wasabi in Korea.

Twenty nine edible plants were selected in order to study their exfoliation effect on abalone Haliotis discus hannai from its substrate. Exfoliation was observed in spearmint Mentha spicata, lemon balm Melissa officinalis, rose flower, onion Allium cepa, wasabi powder, mustard powder, omija Schizandra Chinensis, and hibiscus Hibiscus sabdariffa solutions. In particular, both the omija and hibiscus solutions exfoliated over 90% of the abalone. In field tests, 3% and 4% omija solutions exfoliated 93.6% (850/908) and 97.1% (810/834) of abalone, respectively, whereas 3% and 4% hibiscus solutions exfoliated 96.1% (780/812) and 97.4% (700/719), respectively. The detached abalone were recovered within 1 min 39 seconds. These results indicate that the omija and hibiscus solutions (3% and 4%) may be useful in the exfoliation of abalone.

Rikyu-Konomi and Enshu-Konomi accomplished the base of Japanese Dado as well as has set Japanese representative traditional culture. These are the products of the spiritual culture completed by the ideas of Sen Rikyu and Kobori Enshu, that are Wabi spirit and Kirei sabi spirit combined with the tea. This study is about the interpretation of Japanese traditional space designs related to Rikyu-Konomi and Enshu-Konomi as Japanese Traditional spiritual archetype. The process of this study is illustrated as follows: At first, it mentions the concept of Konomi as self-organizing system, and esthetic characteristics of Rikyu-Konomi and Enshu-Konomi. Secondly, it clarifies internal meanings and spacial characters of Konomi in the Japanese traditional space through the exploring Taian tea house as the example of Rikyu-Konomi, and Bosen tearoom and Katsurarikyu as the examples of Enshu-Konomi. Thirdly, it ascertains Rikyu-Konomi and Enshu-Konomi represented in the contemporary architectural spaces. It analyses the relation between modern traditional space designs and traditional archetypal vocabularies, and examines those spaces from an esthetic point of view for modern implication of Rikyu-Konomi and Enshu-Konomi. In conclusion, it clarifies the contemporary significance of Rikyu-Konomi and Enshu-Konomi in terms of japan traditional space design.

Listeria spp. from sea water, fishes and shellfishes have been troubled in many countries. So we exam ined its distribution rates, biochemical characteristics of a separated strain, growth curve of pH at set times to 4 species of standard strain, and yes or no of growth inhibition for precautionary measure of food poisoning by L. monocytogenes, garlic, mustard, wasabi, and green tea extracts including sensitivity of antibiotics 10 species. As its results, check numbers of its positivity to Listeria spp. were 32 species in total examination body 200 species, and its isolation rates were 16%, L. innocua was 14.0%, L. monocytogenes 1.0%, and L. seeligeri 1.0% by the strain species. All the standard strain of 4 species showed growth inhibition bellow pH 3.0, its pH conditions of the optimum growth at 7.0∼8.0, and its growth was more active in alkali co]tuition than in acid condition. Its growth inhibition examination by garlic extracts had an the worst effects with O.D values of 0.078∼0.210. But the case of mustard and wasabi had weakened effect, and the case of green tea had some effect as the time went by. The results of sensitivity examination of antibiotics 10 species were as fellows. L. innocua of the 16 cases showed sensitivity of 100% in all 5 species, Ampicillin, etc, and Ciprofloxacin showed sensitivity of 43.7% and gentamicin, 93.7%. But tetracycline showed tolerance of 31.3% , cefotaxine. 75%, nalidixic acid, 100%. L. monocytogenes of the 6 cases showed sensitivity of 100% in all 6 species, ciprofloxacin, etc.
