  • We made the Toha-jeot added cabbage kimchi with Toha-jeot, which is salt-fermented Toha shrimp in Korean traditional fermented food. The physicochemical characteristics of cabbage kimchi for 5 week fermentation at 4$^{\circ}C$ were observed. The salt content was 2.10~1.50% during the fermentation period. The salt content decreased rapidly during the first week, stayed the same level until the 4 week and then decreased after the 4 week. The pH of control kimchi and Toha-jeot added cabbage kimchi were 5.69, 5,64, respectively on preparation day. The rate of decrease of pH of Toha-jeot added cabbage kimchi was slow as the fermentation processed. The total acidity of the two kinds of kimchi was increased. The total acidity was higher from Toha-jeot added cabbage kimchi than control cabbage kimchi at the later stage of fermentation. The contents of total sugar and reducing sugar were higher from Toha-jeot added cabbage kimchi than control cabbage kimchi at the early stage of fermentation. The total sugar and reducing sugar contents of the two kinds of cabbage kimchi were decreased gradually as the fermentation processed. The ascorbic acid contents of the two kinds of kimchi were decreased slightly at the early stage of fermentation and then increased from 2 to 4 week, while there was no further change at 5 week.

  • Growth monitoring of highland Kimchi cabbage is very important to respond the fluctuations in supply and demand from middle of August to early September in Korea. For evaluating Kimchi cabbage growth, it needs to classify the transplanting period of Kimchi cabbage, preferentially. This study was conducted to estimate the transplanting period of highland Kimchi cabbage from 2015 to 2016 in the main production area of highland Kimchi cabbage, Anbandegi, Maebongsan, and Gwinemi. Correlation between NDVI (Normalized Difference Vegetation Index) from UAV images and days after transplanting of Kimchi cabbage was high in early transplanting period. But because the growth curve of Kimchi cabbage showed S-type, joint use of multi-temporal linear regression equation for estimation of transplanting period was more suitable. Using application of these equations at Anbandegi, Maebongsan, and Gwinemi, we made the map of transplanting periods of highland Kimchi cabbage. Generally, highland Kimchi cabbage is harvested in sixty days later since transplanting. As a result, we could estimate the harvest time and area of highland Kimchi cabbage.

  • Cabbage, which is one of the main materials of kimchi, normally has an unstable supply due to cultivation and climate conditions. This unstable supply negatively affects the profitability of kimchi processors in Korea. Thus, kimchi processors found a better method for acquiring a consistent cabbage supply with long-term storage of over 3 months. However, a consensus regarding the best method for the stable and economical acquisition of cabbage remains controversial. This study aimed to analyze the current issue concerning cabbage acquisition by kimchi processors and evaluate the economic feasibility of kimchi storage. Findings obtained through survey and economic analyses using theoretical methodology were as follows: First, A survey conducted on kimchi processors in Korea revealed that even though they recognize the importance of kimchi storage, they struggle to store adequate amounts of cabbage. This is particularly evident with summer cabbage, which experiences the highest supply volatility and thus requires greater attention from kimchi processors in terms of storage. Second, the price analyses using the coefficient of variation show that cabbage in Korea has a high level of price instability, which suggests more storage of cabbage. Third, the evaluation of the economic feasibility of cabbage storage indicated that kimchi processors should consider storing a greater amount of cabbage, particularly during the summer season. This approach can help reduce the overall cost associated with kimchi processing.

  • This study was designed to investigate foreigner preferences for the sensory characteristics of kimchi with different fermentation periods. After fermentation in a 5 freezer for 1, 7, and 15 days, Red Chinese Cabbage Kimchi, White Chinese Cabbage Kimchi, Kkakdugi, Chonggak Kimchi, Cucumber Kimchi, Green Onion Kimchi, and Mustard Kimchi were served to the respondents. The respondents had resided in Seoul and Kyunggi province for 3 years or less, and were from Asia, Europe, and the Middle East. Most respondents (62.9%) consumed a Korean meal daily, and 45% of all respondents reported eating kimchi 3 or 4 times a week. As a result, it can be said that foreigners residing in Korea preferred to eat kimchi as a side dish. Based on the respondents answers, we were able to determine the relative popularity of the different types of kimchi. They were, from most popular to least popular, Red Chinese Cabbage Kimchi, Kkakdugi Kimchi, Cucumber Kimchi, White Chinese Cabbage Kimchi, Chonggak Kimchi, Green Onion Kimchi, and Mustard Kimchi. Among those fermented for 1 day, Cucumber Kimchi was most preferred for its. When evaluating the overall preference of Kimchi, the best was in the order of Chinese cabbage (red)>Kkakdugi>Cucumber>Chinese cabbage (white)>Chonggak>Green onion>Mustard Kimchi. For 1 day in a fermented period, Cucumber Kimchi had the most preferred taste (5.76), appearance (5.66), odor (5.89), and texture (5.70). However, Cucumber Kimchi was least popular after 15 days of fermentation (p<0.01). The most preferred Kimchi after 15 days of fermentation was Red Chinese Cabbage Kimchi. Among the kimchi fermented for 7 days, White Chinese Cabbage Kimchi was most preferred. While foreigners indicated that they were satisfied with all the types of kimchi fermented for 1 day and 15 days, they were not satisfied with any of the kimchi fermented for 7 days, save for the White Chinese Cabbage Kimchi. Kkakdugi Kimchi had very high satisfaction scores for appearance, but low scores in taste. On the other hand, Chinese Cabbage Kimchi had low scores in odor (5.02-5.29), but high in texture (5.37-5.62) and taste (4.80-5.30), which are not factors sensitive to a change in acidity. These results showed that foreigners were generally satisfied with Kimchi, but became less satisfied as the Kimchi ripened. Most foreigners were not satisfied with the types of Kimchi that had a strong flavor. Chinese Cabbage Kimchi became the least sour after fermentation, and Cucumber Kimchi became most sour after fermentation.

  • The purpose of this study is to investigate the sensory characteristics of Toha-jeot added cabbage kimchi by Koreans and Japanese. The sensory evaluation was conducted for the following 9 items such as color, savory taste, carbonated taste, sour taste, hot taste, salty taste, off flavor, texture and overall preference. Sensory evaluation of kimchi was tested by Koreans or Japanese whose ages vary from 30 to 50 years old and each group had 25~30 evaluators. Kimchi at different stages of fermentation day 0, 10 and 18th was evaluated. Saltiness of kimchi was 1.5~2.1% through the fermentation period and pH of kimchis was decreased from pH 5.4~5.6 to 4.3~4.4 during the fermentation. The sensory evaluation of Toha-jeot added cabbage kimchi by Koran and Japanese showed the differences in evaluation as the fermentation proceeded. The color, texture and overall preference of Toha-jeot added cabbage kimchi fermentation for 10th days was scored significantly high by Korean group while the score for the savory taste was increased as the fermentation proceeded. The hot taste preference of Toha-jeot added cabbage kimchi fermented 18th days scored significantly high and also increased as the fermentation proceeded by Japanese group. The overall preference of Toha-jeot added cabbage kimchi by Japanese group was higher than that of control cabbage kimchi tested at 10 and 18th days fermentation.

  • Brining property and antimutagenic effects of organically cultivaged Chinese cabbage kimchi (OC kimchi) and common Chinese cabbage imchi (CC kimchi) were studied. The salt absorption rate of leaves was faster than that of stems of the Chinese cabbages. Due to the large portion of leaf in organic Chinese cabbage, organic Chinese cabbage(OC) was much faster in terms of salt absorption rate than common Chinese cabbage(CC). The antimutagenic effects of methanol extracts of CC kimchi and OC kimchi were studied against aflatoxin B1(AFB1) using Ames test on Samonella typhimurium TA 100 and N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) using SOS chromotest. Methanol extract from 6 -day fermented OC kimchi at 15 $^{\circ}C$ showed 80% inhibition rate against the indirect mutage, aflatoxin B1 induced mutagenicit where as that from 6-day fermented CC kimchi at 15 $^{\circ}C$ showed 54% inhibition rate in the Ames test. Methanol extracts from 6-day fermented CC kimchi and OC kimchi showed 27 % and 58 % inhibition rate against direct mutagen , N-methyl-N'-nitro-N-nitrosoguanidine induced mutagenicity, respectively in SOS chormotest, thus OC kimchi exhibited higher antimutagenic activity than kimchi.

  • The antimutagenic effects of buchu kimchi and Chinese cabbage kimchi and theri cytotoxic effects against human cancer cell line were investigated in the Salmonella typhimurium system and MTT assay, respectively. Leek and Chinese cabbage were aslo evaluated in the same system. Buchu kimchi was fermented at 15 $^{\circ}C$ for 4 days . Buchu kimchi samples showed somewhat higher antimutagenic effects against aflatoxin B1(AFB1) than CHinese cabbage kimchi in Salmonella typhimurium TA100 strain. There was no difference onthe antimutagenic activity according to the length of fermentation . Leek exerted stronger antimutagenicity against AFB1 than Chinese cabbage in the Ames assay. In MTT assay, 6-day fermented buchu kimchin revealed the highest cytotoxicity against AGS human gastric adenocarcinoma cells in which 62% and 82% of the inhibition were observed wiht the addition of 100ug, 400ug/well, respectively. Buchu kimchi samples caused 60~70% inhibition on the proliferation of HT-29 at 400ug/well. Leek exhibited higher antiproliferative effect against both AGS cells and HT-29 cells than Chinese cabbage in MTT assay. From these results, it is considered that buchu kimchi has stronger antimutagenic and in vitro anticancer effects than Chinese cabbage kimchi and the high inhibition rate of buchu kimchi probably results from leek, the major ingredient of buchu kimchi .

  • 절임배추와 양념으로 구성된 제품에 대한 품질 특성 정보를 제고하고, 버무린 형태로 저장된 김치와 절임배추와 양념을 분리 저장한 후 버무린 김치의 품질 특성의 차이를 확인하기 위해 $4^{\circ}C$에서 저장하면서 1주 간격으로 품질특성을 분석하였다. 절임배추의 산도 및 일반세균수 변화 결과, 염수 침지에 따른 절임배추의 품질유지 효과가 나타났으며, 외관 및 관능적 품질 특성 결과를 토대로 염수 침지하지 않은 절임배추의 저장한계는 1주, 염수침지한 절임배추의 저장한계는 2주 이내임을 알 수 있었다. 특히, 염수량이 많을수록 품질 유지에 더욱 효과적이었으며 관능적 특성에서도 다소 높은 점수를 받았다. 양념은 저장 8주 동안 산도가 증가하는 경향을 보였으나 미생물학적 및 관능적 품질특성에는 큰 변화가 없었다. 0일차에 제조하여 $4^{\circ}C$에서 저장한 김치와 $4^{\circ}C$에서 각각 저장된 절임배추와 양념을 이용하여 매주 제조한 김치의 품질 특성을 분석한 결과, 0일차에 제조하여 저장한 김치보다 저장된 절임배추와 양념으로 매주 제조한 김치의 pH가 높고, 산도가 낮아 발효 지연효과가 있는 것으로 나타났다. 특히 3주차 저장된 절임배추와 양념으로 제조한 김치의 경우 신냄새, 신맛 등의 지표에서 김치형태로 저장된 것보다 유의적으로 낮은 점수를 받았다. 전반적인 기호도에서도 분리 저장 후 제조한 김치에서 높은 점수를 받았으나 유의적인 차이는 확인되지 않았다. 이상의 결과, 절임배추와 양념으로 제품화할 경우 절임배추는 품질유지를 위해 염수에 침지하여 포장하는 방법이 효과적이며, 분리 저장된 절임배추와 김치 양념을 혼합하여 김치로 제조하여도 처음부터 김치 형태로 제조하여 저장한 것과 비교하여 발효가 지연되면서 관능적으로도 문제가 없어 김치의 가식기간을 연장할 수 있는 방법이 될 것으로 생각된다.
