The purpose of this study was to test the overall preference of Saury fishmeat nuggets. In order to remove off-flavor of Saury and to improve the sensory properties of Saury fishmeat nuggets, different concentrations of vegetables (onion, 0-20%), different types of spices (ginger powder, white pepper powder, garlic powder) and different types of vegetables (onion & hot pepper, onion & pimento, mushroom & hot pepper, and mushroom & pimento) were added and the sensory properties were evaluated. Different types of herbs (Anthemis nobillis, Rosemarinus offcinalis L) and oriental herb (Angelica gigas Nakai, Acanthopanax sessiliflorus Seed) extracts were included as well to preserve the antioxidants in the nuggets after reheating. The main ingredients included saury mince, mild pizza cheese, hydrated textured soy protein, and egg white powder. The samples were molded (dia. 4.5 cm, thickness 1.5 cm, 20 g), lightly battered and fried for 2 min (2 time) at $160^{\circ}C$. The samples were then frozen, reheated ($150^{\circ}C$, 20 min) and subjected to a sensory evaluation. In the sensory evaluation, Saury nuggets made with a vegetable concentration of 15% had the highest flavor, taste, and overall preference (V5). In addition, Saury nuggets made with 1 g of ginger powder and garlic powder scored the highest in the preference test (S2). Saury nuggets made with onion and pepper had the highest score in the preference test relative to all the other tested vegetables (SV1). Finally, in terms of the herb and oriental herb extracts, the nuggets made with the condensed extracts at a 1/20 ratio of Acanthopanax sessiliflorus Seed (AS) scored the highest in the preference test, since AS had the lowest off-flavor taste.

Drought stress is one of major environmental stresses in plants; this leads to reduce plant growth and crop yield. In this study, we selected fungal isolate for mitigating drought stress in pepper plants. To do this, 41 fungi were isolated from rhizosphere or bulk soils of various plants in Jeju, Gangneung, Hampyeong in Korea. Out of 41 isolates, we screened two isolates without phytotoxicity through seed germination of tomato, pepper, and cabbage treated with fungal spores; through following plant assay, we selected GL02 as a candidate for alleviating drought stress in pepper plants. As a result of greenhouse test of pepper plants in drought condition, the stomatal conductance on leaves of pepper plants treated with GL02 was increased, whereras the malondialdehyde (MDA) and electrolyte leakage were decreased compared to that in control plants. When stressed plants were rewatered, stomatal conductance of the plants treated with GL02 was increased; the electrolyte leakage was decreased. Based on internal transcribed spacer (ITS) sequencing analysis, isolate GL02 was belonging to genus Trichoderma. Taken together, drought stress in pepper plants treated with GL02 was alleviated, when it was rewatered after drought-stressed, the plants could be recovered effectively. Therefore, Trichoderma sp. GL02 could be used as a bio-fertilizer to alleviate drought stress in pepper plants.

Sixteen seed samples of nine vegetable crops imported from Japan were tested for plant quarantine by routine methods of seed health testing. Nineteen species of fungi including Alternara alternata were identified from the seed samples. Some species were very frequently detected in the seeds. In this experiment, Verticillium albo-atrum, V. dahliae and Macrophomina sp. from the seeds of spinach, and Cercospora capsici, Drechslera hawaiiensis and V. albo-atrum from the seeds of sweet pepper were detected for the first time, respectively. It has been reported that they had a pathogenicity on some vegetable crops in Japan and other countries. The data suggest that an epidemic damage may be occurred if the infected seeds are sown and cultivated in Korea.

Antimutagenic effects of extracts from curry powder and its individual fourteen kinds of spices, were investigated by Ames test. The antimutagenic effects against a direct mutagen, 2-nitrofluorene(2 -NF) and two indirect mutagens, 2-anthramine(2-AT) and 2-acetamidofluorene (2-AE) in the S. typhimurium TA98 were tested. For the 2-NF, the antimutagenicity of cinnamon, fenugreek, fennel, ginger, clove, turmeric and celery seed were determined as 42, 38, 32, 28, 24, 23 and 20%, respectively. The antimutagenicity of clove against the 2-AT was the highest (116%), and followed by the order of celery seed(103%), cardamon(100%), red pepper(99%), cinnamon(92%), cumin(83%), ginger(82%), fennel(82%), coriander (71%), nutmeg(68%) and turmeric (55%). The results also showed that the antimutagenic effect of clove against the 2-AF was superior to other spices. In case of curry powder among more than 10 kinds of spices, the antimutagenenicity against the 2-AT and 2-AF showed 23% and 6%, respectively, but no effect was observed against the 2-NF.

To investigate some factors on oleoresin extraction from red pepper, the content of yield, capsanthin and capsaicin in oleoresin extracted under various factors such as solvent, variety of materials, extraction time and temperature, storage condition of dried red pepper and its parts, particle size of raw material powder and the ratios of red pepper powder to extraction solvent were investigated. Ethyl alcohol and ethylene dichloride were effective in extracting capsanthin and capsaicin from red pepper, respectively. Mixed-solvent bore fruitful in increasing of oleoresin yield, but was fruitless in extracting capsanthin and capsaicin in comparison with single-solvent. In three varieties such as Juktoma, Jinsol and Dabok, Jinsol was excellent in oleoresin extraction. Optimum extracting temperature and time was $20^{\circ}C$ and three to five hours, respectively. Oleoresin quality from long-term storage and/or coarse red pepper were low in point of yield, capsanthin and capsaicin. Capsanthin and capsaicin were distributed into pericarp and seed in abundance, respectively. Optimum mixing ratio of red pepper powder to extracting solvent was suitable for one to three(1 : 3) or one to four(1 : 4) in oleoresin extraction.

This study was designed to observe the effects of the fish oil and some seed oils on the improvement of the fatty acid compositions of liver and brain tissue in rats. In order to induce the hypertriglyceridemia in the rats of the Sprague-Dawley, 12% coconut oil and 3% each of olive oil, lard, fish oil, perilla oil, corn oil, red pepper seed oil and evening primrose oil were administered to the rats for 4 weeks. In the fatty acid composition of liver lipid, n-3 PUFA contents were most in the fish oil and perilla oil groups of phospholipid fraction, and n-6 PUFA contents were most in the corn oil, red pepper seed oil and evening primrose oil groups of triglyceride fractions. Fatty acid composition of liver lipid fractions were influenced from the fatty acid composition of the test lipids. In the fatty acid composition of brain phospholipid, n-3 PUFA contents (8.8~17.2%) were most in the fish oil group, and n-6 PUFA (34.6~38.2%), though it contains high percentage, showed little difference between groups.

To get a basic information for improving Korean's pattern of comsuming red pepper and the possibility of its industrial production, consumer's ways of red pepper processing and his present dietary habits were surveyed and the results are follows; (1) Korean's daily consumption of red pepper was on the average 9.2 g on the basis of the whole dried red pepper. (2) The tendency of evading the home drying method was increased; 72.22% in urban community and 50.4% in rural community purchased the dried red pepper in the lump yearly. The household purchasing the fresh red pepper and using the home drying was 27.8% in urban community and 49.6% in rural community, so one third of urban household was still using the home drying method. The case of dependence on tine drying factory was no more than 2.6%. (3) Drying method was mainly sun drying which done on the poor circumstance like as the street side without the proper equipment of drying. Home process of red pepper by housewife was 70.8%, and the old, housekeeper were only 7.3% respectively. (4) The hygienic sense in the drying was rare; 68.8% was not washed and 51.9% of decayed red pepper was eaten. (5) Koreans prefered the strong pungency, deep red color and fine powder form. (6) While the 45.5% of seed was collected by second hand dealer and made use of as resources of edible oil, it was not used effectively due to complexity of its collection system. (7) While 40.1% desired the improvement of red pepper dietary life, 41.1% distrusted the present commercial red pepper powder on the market. From the results above, we conclude the fact many households have still hygienically poor red pepper processed at home, in spite of the red pepper is one of the most important spices in Korea. Considering the growing urban population, reduction of unemployed labor due to the increasing nuclear family and hygienic problems caused by the serious pollution, the improvement of red pepper processing method is urgently required. And it is believed that red pepper has a good prospect to be processed on the industrial scale in Korea.

Primed seeds germinate faster and uniformly, since these have already started imbibition and metabolism requiring to complete germination. Several factors such as solution composition, osmotic potential, and treatment duration affect seed priming response. Water potentials of priming solution and germination response of primed seed were investigated to clarify the effects different inorganic salt types and the duration. Pepper seeds were primed in osmotic solutions that were osmotic potential ranged -1.54 to -0.45 MPa in an aerated solution of polyethylene glycol 8000 (PEG; 17%, 22%, 27%), and inorganic salt solution of $KNO_3$, $K_2SO_4$, and $Na_2SO_4$ (100, 200, 300mM) in aerated condition. The seeds were treated at $20^{\circ}C$ for 4, 6 day (D) and stepwise duration combined concentration of 100mM (2 or 4 days) and 300mM(2 or 4days). After soaking treatment, seeds were washed with distilled water and then were dried to approximately 6% moisture content in dry chamber at $25^{\circ}C$. The germination of seed was characterized by ISAT rules at $20^{\circ}C/30^{\circ}C$ and $15^{\circ}C$. Total germination percentage (GP), mean germination time (MGT), germination uniformity (GU), germination rate (GR), and health seedling percent (HS) were calculated on the germinated seed in a 14-day period. Seed water potential (${\psi}$) was correlated with water potential of priming solution ($r^2=0.84$). The effect of seed priming on germination varies with inorganic salt and organic agents (PEG). Germination percentage (GP, 77 and 73%), GR (21.3 and $19.4 %{\cdot}day^{-1}$), and HS (58 and 52 %) was greatest and lowest MGT (4.2 and 4.8 day) when they were primed in 100mM $K_2SO_4$ (${\psi}=-0.45MPa$), and 100mM $KNO_3$ (${\psi}=-0.52MPa$) for 6 days compared to untreated control (67% GP, $19.7%{\cdot}day^{-1}\;GR$, 18% HS, and 10.8 day MGT) in $15^{\circ}C$ chamber. Water potential less then -1.2MPa of osmotic solution resulted lower GP, GR and HS and in $K_2SO_4$ and $KNO_3$. However, stepwise treatment of water potential that changed solution as 100mM for 4 D + 300mM for 2 D or 300mM for 4 D + 100mM for 2 D) were not better than single concentration alone in germination characteristics.

Plant growth promoting rhizobacteria (PGPR) have been shown to suppress phytopthora blight. This suppression has been related to both microbial antagonism and induced resistance. The PGPR isolates were screened by dual culture plate method and most of the isolates were showed varyinglevels of antagonism. Among the PGPR isolates pyoverdin, pyochelin and salicylic acid producing strains showed the maximum inhibition of mycelial growth of Phytophthora capsici and increased plant growth promotion in red pepper. PGPR isolatesfurther analysed for its ability to induce production of defence related enzymes and chemicals. The activities such as Phenyle alanin ammonia lyase (PAL), Peroxidase (PO), Polyphenol oxidase (PPO) and accumulation of phenolics were observed in PGPR pretreated red pepper plants challenged with Phytophthora capsici. The present study shows that an addition of direct antagonism and plant growth promotion, induction of defense related enzymes involved to enhance resistance against invasion of P. capsici in red pepper.

This study was conducted to standardize ingredient ratio and preparation method of mafor traditional special kimchies in kyungsang province, korea. There were about 35 varieties of special kimchi in Kyungsang province. Six varieties of them such as burdock kimchi, wild leek kimchi, green thread onion kimchi, perilla leaf kimchi, Godulbaegi(Korean wild lettuce) kimchi, and red pepper leaf kimchi were selected, because they tasted good and the physiological functions of their main ingredients were excellent. The ingredient ratios of the selected special kimchi were standardized through surveying hereditary preparation of some families in kyungsang province and using the literatures including cooking books. The standardized ingredient ratio of the burdock kimchi was 15.1 pickled anchovy juice, 6.8 red pepper powder, 5.7 garlic, 2.2 ginger, 18.0 rice flour paste, 13.5 green thread onion, and 1.2 sesame seed in proportion to 100 of burdock. The standardized preparation step of the selected special kimchies was similar except some preprocessing methods of main ingredients. The diagonally cut-up burdock ws usually parboiled or soaked in salted water, then it was mixed with the other ingredients. Wild leek and green thread onion were usually pickled with salt or pickled anchovy juice. Sometimes the green thread onion pickled was dried in the sun. General preprocessing of perilla leaf, Korean wild lettuce, and red pepper leaf was soaking them in salted water for about 5-10 days. Sometimes red pepper leaf was heated with steam and dried in the sun, then it was mixed with the other ingredients.
