The quality characteristics of semi-dry red pepper (SDRP) (Capsicum annuum L.) were compared with raw and dry red pepper (DRP). Raw red pepper was divided into pieces and the semi-drying treatment involved air-drying at $65^{\circ}C$. The study focused on describing the characteristics of semi-dry red pepper in comparison with dry red pepper. Factors considered were reduced drying period, ASTA color, capsanthin, capsaicinoids, free sugars and vitamin C content. ASTA color, capsanthin, capsaicinoids, free sugars and vitamin C content of SDRP were higher in SDRP than in DRP for 15 g or less water per 100 g. Red pepper powders made using the semi-drying method showed the highest amount of glucose and vitamin C. Capsanthin content in SDRP (151.6155.9 mg/100 g) was significantly higher than for DRP (133.4 mg/100 g). The capsaicinoid content of SDRP was about 13-25% higher than in DRP. The ASTA values (148.7159.3) for SDRP were much higher than for DRP (139.5). The vitamin C and free sugar content of SDRP was 40-76% and 20-40% higher, respectively, than for DRP. and $20{\sim}40%$, respectively, by SDRP compared to DRP.

장류 중 비교적 늦게 우리식생활에 도입된 고추장은 고추의 도입시기인 임진란 이후 장류의 기본인 메주와 어울려 채소류 중심의 우리 식생활에 도입되었을 것이며 지금은 우리의 모든 요리에 광범위하게 이용되고 있는 향신 조미료의 하나로 세계에 그 유례를 찾아볼 수 없다. 고추장은 크게 나눠 전통고추장과 개량식으로 구분하는 바 가장 큰 차이점은 전자는 자연 발효한 고추장 메주를 사용하는 반면 후자는 순수 황국균에 의한 koji를 이용하면서 최종 제품에 가열과정이 없는 것이다. 우리나라 고추장 수요량은 약16만 톤 정도며 매출액은 약 1,165억 원으로 추산되는데 그중 60％가 공장산으로 고추장의 제조가 급격히 주부의 손을 떠나고 있다. 전통고추장의 비중은 전체 고추장에서 미미하나 아직도 상당수의 소비자에게서 선호되고 있으며 중소형 혹은 가내 규모로 농민의 소득증대에 기여하고 있다. 전통고추장의 문제는 자연발효에 의한 품질균일화 미흡과 품질개선 노력이 부족한 점과 유통 중 변색 및 가스생성에 의한 팽창과 내용물 유출인바 이번 연구를 통하여 변색의 주원인은 빛(U.V.)과 열 임을 밝혔고 주로 효모에 의해서 발생되는 가스 및 내용물의 유출문제는 천연 항균성 물질을 함유한 양고추냉이와 겨자를 첨가하는 경우 성공적으로 방지할 수 있었으며 품질도 오히려 개선되는 결과를 얻었다.

Antifungal activities of the crude extracts of Anemarrhena asphodeloides. Coptis japonica and Phellodendron amurense were tested against Phvtophthora capsici. and the control effect on red-pepper phytophthora hlight and phytotoxicities of red-pepper were investigated. The results were summarized as follows; Mycelial growth and zoosporangial germination of the red-peppcr phytophthora hlight organism P. capsici were inhihited hy thc crude extracts of plant materials. Methanol extracts or plant materials had hctter antifungal activity than water extracts at hoth a room temperature and a hoiling condition. Antifungal activities of three crude extracts were gradually decreased with prolonged storage period. Red-pepper phytophthora hlight was effectively controlled hy the crude extracts of three plant materials. Of these. the crude extract of C. japonica was marvelously effective. Phytotoxic symptom to red-pepper seedling showed hy water cultural method hut not by pot test. Seed germination and radicle growth of red-pepper were inhihited hy the crude extracts of three plant materials. Phytotoxic symptoms in the leaves and fruits of red-pepper were not ohserved with exogenous foliage application of the three crude extracts.

This study was investigated to obtain basic information for the development of irrigation plans in upland cultivation of Wasabi. Changes of stomatal conductivity and photosynthetic rate of Wasabi, and of the soil water potential during withholding watering were analysed. The stomatal conductivity of Wasabi at $1000{\mu}Em^{-2}s^{-1}$ light intensity was $70mmolem^{-2}s^{-1}$, which was about 49% lower than that of Chinese cabbage, $138mmolem^{-2}s^{-1}$. The temporal changes of light intensity during the daytime did not influence the stomatal conductivity. The soil water potential that decreased stomatal conductivity in Wasabi was about - 50kPa at 10 AM, and about - 30kPa at 3 PM. The photosynthetic rate of Wasabi at$1000{\mu}Em^{-2}s^{-1}$ light intensity was $7.6mgdm^{-2}hr^{-1}$, which was about 50% lower than that of Chinese cabbage, $15.3mgdm^{-2}hr^{-1}$. The duration required for a stable photosynthetic rate was longer in Wasabi than in Chinese cabbage. The soil water potential that decreased photosynthetic rate in Wasabi was about - 50kPa at 10 AM, and about - 30kPa at 3 PM. The stomatal conductivity and photosynthetic rate showed significant positive correlation at various soil water potential. The results indicated that irrigation in wasabi could be done during the daytime when the soil water potential is above - 30kPa, which does not decrease stomatal conductivity and photosynthesis in Wasabi.

To evaluate the exposure of molinate in agricultural environment and its effect against the non-target crop in air, this experiment was conducted to elucidate volatilization characteristics of molinate in aquatic condition and to determine critical concentration of molinate in the air causing phytotoxicity to Chili pepper. Cumulative volatilized rate of molinate from water was 22.7% at $35^{\circ}C$ for water temperature and 20 L/min for air velocity while 3.2% at $25^{\circ}C$ and 10 L/min within 47 hour after applied under closed system, respectively. The molinate concentrations in air above 60 cm height from soil surface of valley and open paddy rice field were reached the highest value of 18.17 and $11.59{\mu}g/m^3$, respectively within 24 hours after applying granular formulation at dose rate of molinate 150 g/1,000 $m^2$. However, their concentrations were drastically diminished to around 0.18 and $0.51{\mu}g/m^3$ level in 20 days after application, which volatilization pattern were similar to both regions. Also, the concentration of molinate in air above 60 cm height from soil surface was distributed higher 2 times than that above 180 cm height. Meanwhile, a phytotoxic symptom against the nearby chili pepper was revealed within three days after applied and molinate was detected $0.004{\sim}0.006$ mg/kg level from severe damaged leaves. The dose and exposure relations of molinate in the air against the non-target crop was also investigated in lab trial. The phytotoxic symptom, shriveled leaves, of the chili pepper was encountered by exposing two days with concentration of $13.6{\mu}g/m^3$, three days with $6.8{\mu}g/m^3$ or four days with $3.4{\mu}g/m^3$. The symptom was still recovered within four weeks after the plants had received fresh air. On the other hand, the phytotoxic response through root uptake of the herbicide in water culture was relatively insensitive, in which the symptom is observed ten days with the concentration of 300 ${\mu}g/L$.

One of the most important vegetables consumed in Korea, chili peppers (Capsicum annuum) are widely cultivated around the world. Chili peppers have been severely damaged by anthracnose during their growth, so it is important to study prevention and resistance varieties. K1 anthracnose was inoculated against four cultivar of chili peppers that are resistant to anthracnose and one cultivar that is sensitive. The area of the disease that appeared over time was photographed and quantified through the program was analyzed. Through the ratio of the area of chili pepper fruit and the area of the bottle, the sensitive variety An-S showed weak reactions to anthracnose with about 40%, the resistant variety An-12R (23%), An-Tan (21%), and An-9R (19%), and PBC81 showed a strong response to anthracnose with about 11%. These quantitative value can be used as a basis for comparison in conducting resistance studies for new varieties.

총고형분 함량$(TS:\;50{\sim}57%)$을 달리하여 숙성시킨 고추장의 유동특성, 정적 및 동적점탄특성을 관찰하였다. 고추장의 TS가 증가함에 따라서 점조도 지수(K)와 겉보기 점도$({\eta}_{a.5})$는 증가하였으며 유동성 지수(n)는 1보다 훨씬 낮은 0.24-0.31의 범위를 나타내어 고추장은 shear-thinning 성질을 보여주었다. 고추장의 항복응력 측정에서는 고추장의 TS가 증가함에 따라 Casson 항복응력$({\sigma}_{oc})$은 증가하는 경향을 나타내었으며, 또한 고추장의 액상 매개체인 serum 점도$({\eta}_{se})$는 고추장의 TS와 매우 좋은 상관관계$(R^2=0.97)$를 나타내었다. 고추장의 동적점탄성 실험에서는 주파수$({\omega})$가 증가함에 따라 저장탄성률(G#)와 손실탄성률(G@)은 증가하였으며 양(+) 기울기로 G#수치가 G@수치보다 높게 나타났다. 이는 고추장이 약한 겔과 같은 구조적 특성을 갖고 있으며 또한 shear-thinning 거동을 가지고 있음을 나타낸다. 정적점탄성 실험에서 고추장의 총고형분 함량에 따라서 순간탄성 변형$(J_0)$과 지연탄성변형$(J_1)$은 총고형분 함량이 증가함에 따라서 감소하였으며 점도$({\eta}_N)$와 지연시간 $({\tau}_1)$은 증가하였다. 따라서 고추장은 농도가 증가함에 따라 보다 탄력적이며 안정된 구조를 형성하고 있음을 알 수 있었다.

The contents of capicin according to the growth of fresh red peppers (Capsicum annum) and to-brewing of 'kochujang' (fermented hot peper-soybean paste) and 'kimchi' (a group of Korean seasoned pickles) were quantified by High Pressure Liquid Chromatography. Colors of the peppers were evaluated by Hunter Value and quantity of capsanthin. The content and chemical structure of capsaicin after heat treatment were traced by HPLC, GCMS, UV and NMR. It was found that the capsaicin content of red peper was highest 6 to 7 weeks after flowering and that peppers with high Hunter Value contained higher level of capsanthin. The content of capsaicin of kochujang and kimchi declined by 20% and 17% respectively, as they are brewed. Capsaicin content was decreased by heating. However, change in its chemical strtcure was not occurred.
