  • In vitro plant regeneration of inbred breeding line of hot pepper (Capsicum annuum L.) was established using leaf and petiole segments as explants. About 28 days old plants were excised and cultured on MS medium supplemented with TDZ and NAA or in combination with Zeatin. In all of the media compositions tested, combination of TDZ 0.5 mg/L, Zeatin 0.5 mg/L, and NAA 0.1 mg/L was found to be the best medium for shoot bud initiation. Young petiole was the most appropriate explant type for the plant regeneration as well as genetic transformation in hot pepper. In this study, HpMADS1 gene isolated from hot pepper was introduced using Agrobacterium-mediated transformation system. Based on the analysis of Southern blot and RT-PCR, HpMADS1 gene was integrated in the hot pepper genome. It has been known that floral organ development is controlled by a group of regulatory factors containing the MADS domain. Morphological characteristics in these transgenic plants, especially flowering habit, however, were not significantly altered, indicating this MADS gene, HpMADS1 may be non-functional in this case.

  • 밭 농업 기계는 심한 경사지와 험로, 재배 작물별 정형화되지 않은 재배양식으로 인해 개발이 어렵다. 특히 고추 수확 작업은 많은 시간과 인력이 요구되는 작업으로 고령화가 가속화되는 국내 농촌의 큰 문제점이다. 본 연구는 부족한 인력을 대체하고 작업 시간을 줄이며 수확 작업을 기계화하기 위해 개발된 고추 수확기의 동적 특성을 연구하고자 한다. 고추 수확기의 동적 특성을 분석하기 위해 동역학 프로그램인 Recurdyn을 이용하여 진행하였으며 모든 분석은 공차를 전제로 분석을 진행하였다. 시뮬레이션 결과에 따라 주행 플랫폼이 주행할 수 있는 안전 범위를 제시하였다.

  • 본 연구는 고춧가루 추출액의 혼합 비율에 따른 고추씨 추출액의 매운맛에 대한 영향을 조사하기 위하여 수행되었다. 고추씨 추출액에 첨가하는 고춧가루 혼합비율이 증가할수록 수율 및 점도, 탁도, a와 b값은 증가하였으며 L값은 감소하는 경향을 보였다. 또한 시간차 강도 평가에 의한 관능검사 결과 고추씨 추출액은 매운맛이 완만히 증가하였으며 후기에도 그 강도가 유지되는 것에 반하여 고춧가루 추출액은 단시간에 매운맛에 도달한 후 급격히 감소하는 경향을 나타내었다. 고춧가루와 고추씨 추출액의 혼합 비율은 그들 자체가 지니는 매운맛 특성에 의해 영향을 받음을 알 수 있었다.

  • This study examined the changes of side dishes in "Eumsikdimibang", "Gyuhapchongseo", "Chosunmusangsinsikyorijebub" over time. As food ingredients, seaweed, red pepper, salted fish, Korean hot pepper paste have been used in "Gyuhapchongseo". The use of cattle by parts, saltwater fish, Chinese cabbage, powdered red pepper, garlic have increased in"Chosunmusangsinsikyorijebub". Cooking techniques, such as the use of wheat flour, a double boiler by the use of steam, and boiling and then roasting cuisine were mostly used in"Eumsikdimibang", but reduced in"Gyuhapchongseo". In "Gyuhapchongseo", the cooking methods are primarily aimed at a positive visual effect, and slices of dried meat seasoned with spices have increased. In"Chosunmusangsinsikyorijebub", various Tang (Guk), the taste of food changed by controlling the gravy content (Gigimi, Chigye, Chorim), meat mixing oil, vegetable and mushroom together to cook and boiling down the main food ingredients to soak the seasoning were increased. Dog-meat steamed dish using the intestine of dog in "Eumsikdimibang" was changed to small intestine of cattle steamed dish in "Gyuhapchongseo". And seasoned dog meat with choncho in "Eumsikdimibang" influenced on beef tail soup with Korean hot pepper paste in "Gyuhapchongseo", and Yookgyejang soup using Korean hot pepper paste in"Chosunmusangsinsikyorijebub". In steamed young chicken, the stuffing such as soybean paste, choncho, welsh onion, leek and flour in "Eumsikdimibang" was changed to minced beef, welsh onion, dropwort and Shiitake mushroom in"Gyuhapchongseo". The steamed young chicken in "Chosunmusangsinsikyorijebub" with stuffing was added to chicken soup using glutinous rice, and ginseng powder. Now, the chicken soup was changed to Samgyetang with glutinous rice, and ginseng. In "Chosunmusangsinsikyorijebub", various vegetable dishes were cooked with beef.

  • 고춧가루를 보다 위생적이고, 영양소의 파괴를 막으며 또한 홍고추의 색상을 유지하기 위하여, 한반도와 부자의 2가지 품종을 이용하여 반건조 고춧가루를 제조한 후 화력건조 고추가루와 비타민 C, ASTA color 값, 총세균수를 비교하였으며, 또한 이 두 고춧가루로 김치를 제조하여 그 품질의 특성을 비교한 결과는 다음과 같다. 비타민 C 함량과 ASTA color 값은 반건조 고추가루가 화력 건조 고춧가루보다 더 높게 나타났으며, 총세균수에 있어서는 반건조 고춧가루가 더 낮은 수를 나타내었다. 또한 2가지 고춧가루로 김치를 제조한 후 $7^{\circ}C$에서 발효시키면서 PH, 총산도, 총세균수 및 젖산 균수의 변화를 관찰한 결과, 기존의 화력건조 고춧가루로 제조한 김치의 pH, 총산도, 총세균수 및 젖산균 수의 변화 등에서 별 차이를 발견하지 못하였다. 관능검사 결과, 한반도 품종에서 색을 제외한 맛$(3.85\pm0.21)$ 풍미$(3.42\pm0.26)$, 조직감$(3.96\pm0.23)$에서 반건조 고춧가루를 사용한 김치의 선호도가 높게 나타났다. 앞으로 반건조 고춧가루로 김치를 만들면, 경제적일 뿐만 아니라 관능적, 위생적으로 우수한 김치를 생산하여 김치 산업발전에 도움이 되리라 생각된다.

  • This study investigated the heat level rating of several varieties of Korean red peppers. The chemical constitution of Korean red pepper samples were as follows: 0.54~290.15 mg% capsaicinoids, 79.22~139.09 ASTA value, and 16.76~29.92% free sugar content. The heat level of the Korean red pepper samples was evaluated by trained panelists and the correlation coefficient and F value (0.001%) of the panelist’s results were determined to be significant. In the principle component analysis (PCA), PC1 (capsaicinoids) and PC2 (free sugar) were shown to represent 31.98% and 25.77% of the total variance, respectively. The results of panelists trained for red pepper heat rating were evaluated using analysis of variance and correlation analysis. The trained panelists showed a high F value (p=0.05) and high correlation coefficient. A high correlation efficient of 0.84~0.93 for the test samples with a 40 Scoville heat unit (32,000 SHU red pepper powder) was reported in the sensory evaluation of the Korean red pepper heat level by a trained panel. However, the panel showed a low correlation efficiency of 0.70 $R^2$ when the 60 SHU test samples were included in the analysis.

  • Hot and spicy flavor grading in hot pepper powder for gochujang in various cultivars was studied using sensory and physicochemical characteristics. Chungyang, which had the highest capsaicin content had very low redness a value of 17.49 representing stronger red color does not relate to the stronger hot and spicy flavor. Sensory results showed that chungyang had significantly the highest value of hot and spicy aroma and flavor of 5.73 and 7.87, respectively(p<0.05). Although wurigun had the second highest capsaicin contents, it had relatively low hot and spicy aroma value as 3.87, some sweet flavor, and relatively low stingingness in the mouth value of 4.67, thus, comparatively weak hot and spicy flavor of 4.87 suggesting the difficulties in grading the hot and spicy flavor only by the capsaicin contents. Capsaicin content was highly positively correlated with the hot and spicy flavor, aftertaste and stinging flavor, and negatively correlated with the sweet flavor. In the principal component analysis, samples of chunyang, balita, and gumbit groups with greater hot and spicy aroma and flavor, were loaded in the first principal component. Classifying hot and spicy flavor of hot pepper powder for gochujang in various cultivars are suggested as 'very weak', 'weak', 'intermediate', 'strong', and 'very strong' with capsaicin contents under 40.00 mg/dL, 40~100 mg/dL, 100~150 mg/dL, 150~500 mg/dL, and those higher than 500 mg/dL, respectively. Since too many sample groups were located in the specific stages in the five stage grading, the nine staged classification is also suggested.

  • The effect of biological control on the severity of hot pepper wilt disease was evaluated in the vinyl house with plants cultivated in the nursery soil containing chitin and chitinolytic microorganisms. The chitinolytic microorganisms, Trichoderma harzianum and Chromobacterium sp. strain C-61, were well survived in the nursery soil containing chitin. The hot pepper damping-off was markedly suppressed in the nursery soil containing chitin and chitinolytic microorganisms. The survival of chitinolytic microorganisms and suppression of damping-off were superior as the amounts of chitin added to the nursery soil increased, but growth of hot pepper was inhibited in the 10% (w/w) chitin treatment. When the plants cultivated in the nursery soil containing 1% chitin and chitinolytic microorganisms were transplanted in the vinyl house, the vegetative growth increased and the wilt disease was reduced as comparison with those of control.
