The roots of Cichorium intybus L. (chicory) have many nutritional qualities and also have been used for health promotion as traditional medicine. The antimicrobial activity of Cichorium intybus L.'s (chicory) ethanol extract on Bacillus cereus ATCC 10876 were investigated using spot on lawn method in this study. Ethanol extract exhibited antimicrobial activities against Bacillus cereus ATCC 10876 with significance. Also, the results produced the larger zones of inhibition against Bacillus cereus ATCC 10876 tested, with increasing concentration of Cichorium intybus L.'s (chicory) ethanol extracts,. Hence, Cichorium intybus L. (chicory) could be served for keeping the safety of various dairy products as natural antimicrobial agents.

질소 시비수준이 치커리의 3가지 품종에 있어 생육과 품질에 미치는 영향을 조사하고자 수행한 본 실험의 결과는 다음과 같다. 1. 30kgN/10a 처리구에서 외형적인 생육이 가장 좋았지만 잎끝마름과 추대 발생율은 20kgN/10a 처리구와 10kgN/10a 처리구에서 보다 낮았다. 2. 품종간 비교에서 ‘Winter’가 다른 품종에 비해 생육이 양호하였으나, 잎끝마름과 추대 발생율도 높았다. 3. Vitamin C 함량은 모든 품종에서 10kgN/10a 와 20kgN/10a 처리구가 30kgN/10a 에 비해 높았고, 품종에서는 ‘Winter’가 높은 수치를 나타내었다. 4. 건물중의 경우 각 품종 모두 30kgN/10a 처리구에서 가장 높게 나타났으나 건물율에 있어서는 20kgN/10a 처리구와 10kgN/10a 에서 높게 나타났다.

This study aimed to evaluate the growth of Cichorium intybus, Brassica juncea, and Lactuca sativa at varying seed ratios, and to suggest an efficient management plan for sustainable indoor agriculture systems. It was treated with mixed sowing as follows: 30 chicory seeds (chicory alone: CC), 22 chicory seeds + 8 lettuce seeds (C₃L₁), 20 chicory seeds + 10 lettuce seeds (C₂L₁), 15 chicory seeds + 15 lettuce seeds (C₁L₁) as intraspecies, and 30 mustard seeds (mustard alone: MC), 22 mustard seeds + 8 lettuce seeds (M₃L₁), 20 mustard seeds + 10 lettuce seeds (M₂L₁), 15 mustard seeds + 15 lettuce seeds (M₁L₁) as interspecies. The study identified the competitive response in seed germination between Cichorium intybus and Lactuca sativa, and in the C₃L₁ experimental group, Lactuca sativa had the highest leaf length, root length, chlorophyll content, and fresh weight. Therefore, the higher the ratio of Cichorium intybus, the higher the growth and productivity of Lactuca sativa; however, higher the ratio of Lactuca sativa, the lower the growth of Cichorium intybus. Furthermore, the nitrogen and potassium content in the substrate was the highest in the C₃L₁ experimental grorp which had the highest seeding rate of the Cichorium intybus. Comparing the groups Brassica juncea and Lactuca sativa, the higher the seeding ratio of Lactuca sativa, the higher the growth and productivity of Brassica juncea. Therefore, a companion seeding of Brassica juncea and Lactuca sativa is beneficial; this could be effective in having a high seeding ratio of Lactuca sativa.

Aroma components of tea processed from Korean chicory roots were isolated and identified. The model system of amino-carbonyl reaction was carried out to study the formation mechanism of aroma compounds of chicory tea during manufacturing process. The concentration extracts from chicory tea and model system were analyzed and identified by gas chromatography(GC) and GC-mass spectrometry. Twenty-nine compounds, including pyrazines, furans, acids, alcohols, pyrroles and lactones were isolated and identified in chicory tea. The main compounds were pyrazines including methyl pyrazine, 2,5-dimethyl pyrazine, 2, 6-dimethyl pyrazine, 2-ethyl-6-methyl pyrazine, 2-ethyl-3-methyl pyrazine, thrimethyl pyrazine, 3-ethyl-2-5-dimenthyl pyrazine, 5-ethyl-2-3-dimenthyl pyrazine, and 2-acetyl-3-methy pyrazine and pyrroles including acethl pyrrole and formlyl pyrrole ; and furans including furfural , acetyl furan, 5-methyl furan, 5-methyl furfuralm, and furfuryl alcohol. These pyrazine compounds of a roasted and nutty aroma may be important contributors to the flavor of chicory tea. The aroma concentrate of model system also had a roasted and nutty aroma and the main compounds were methyl pyrazine, 2, 5-dimetyl pyrazine, 2, 6-dimethyl pyrazine and trimethyl pyrazine.

고랭지에 적합한 신소득 작목을 개발하고자 최근에 수요가 증가하고 있는 쌈채소중에서 적근대 등 17종을 공시하였다. 파종은 128공 플러그트레이에 30일간 육묘하였으며 비가림하우스에 정식하여 생육, 특성, 수량 등 제반 수량형질과 쌈으로서의 재배 및 이용 가능성을 조사하였다. 정식시 묘소질은 공시작목 17종 모두 묘상 및 본포 생육은 고랭지 환경조건에서 순조로운 양상을 보였다. 이들 중에서 부추, 삼엽채 및 로메인상추 등의 첫수확은 8월 상중순이었으나 나머지 작목은 7월 10일이었다. 삼엽채 등을 비롯한 11종은 7월 중순-8월 하순에 추대하여 대부분 개화에 도달하였다. 로메인상추, 화채 등 일시수확하는 작목을 제외한 전 작목 모두 월별 수확이 진행됨에 따라 상품엽의 크기가 점차 감소하였으며 9월 수확시에 그 감소 정도가 다소 컸다. 7-9월의 상품수량은 적근대, 적겨자, 겨자채, 청경채, 다채, 로메인상추, 적엽치커리, 적치커리, 녹엽치커리 등 9작목이 비교적 높은 수준이었다.

The establishment of an efficient protocol for plant regeneration and micropropagation from leaf explant cultures of Chicory, Cichorium intybus L. var. sativus. is reported. Callus formation rate appeared 100% from explant in all growth regulators, but calli formed in the prensence of naphthaleneacetic acid (NAA) were appeared very compact and non-embryogenic state. The regenerated shoots were obtained from leaf explant cultures on solid MS medium containing different concentrations of cytokinins and auxin. The highest number of shoots (5.7) per explant and shoot growth (2.8cm) was obtained on MS medium containing 0.1 mg BAP L$^{-1}$ and 0.1 mg NAA L$^{-1}$ . Indole acetic acid was the most suitable auxin for root formation among three auxins tested. 2,4-D had no effect on shoot and root formation.

치커리(Cichorium intybus L.)의 우량 종근 생산을 위한 휴면 특성을 구명하기 위해 시기별로 생육 특성과 ABA 함량을 조사하였다. $5^{\circ}C$ 이하의 저온누적시간은 10월 7일부터 12월 3일 조사까지는 서서히 증가하는 경향을 나타내었으나 이후 증가폭이 커졌다. 종근 무게는 10월 말부터 12월 3일 조사까지 큰 폭으로 증가하였으나, 이후부터 12월 17일 조사까지 거의 증가하지 않았다. 종근 내 ABA 함량은 10월 7일부터 12월 3일 조사까지 아주 낮은 수준으로 변화가 거의 없었으나, 이후 12월 10일 조사에서 급격히 증가하였고 2주후인 12월 24일 조사에서 급격히 감소하였다. 따라서 $5^{\circ}C$이하의 저온누적시간이 큰 폭으로 증가하고 종근 무게가 변화하지 않는 시기, 그리고 ABA 함량이 급격히 증가하는 시기를 고려하면, 치커리는 12월 3일 이후부터 대략 2주간 내재 휴면을 하고 이를 타파하기 위한 저온요구시간은 대략 240시간 정도로 생각된다.

Made using a natural mixed starter of lactic acid bacteria and yeast, Koumiss is a slightly alcoholic fermented mare's milk beverage, and a traditional drink of the nomadic populations of Central Asia. Cichorium intybus L. (chicory) is a sedative with potential cardioactive properties, and its oligosaccharides are beneficial in maintaining healthy gastrointestinal flora. Hence, in this study, we have generated a functional Koumiss containing two different concentrations of chicory. After fermentation of the Koumiss premix, the TA increased to 0.85~0.88%, and the pH decreased to ~4.3. The addition of either concentration of chicory had no significant effect on pH and TA. However, the taste, flavor, color, texture, and overall acceptability decreased in proportion to the added amount of chicory. This study has provided the first data on Koumiss supplemented with chicory. The results could be useful in developing high-quality Koumiss with functional activity using chicory, and allowing large-scale industrial production. Further studies are needed to determine if chicory root extract is beneficial for lifestyle-related diseases.

Cichorium intybus L. (chicory) roots and leaves are widely used in herbal preparations, which have beneficial effects on the stimulation of digestion and metabolism of food ingredients, gastric juice excretion, diuretic action, and bile excretion. Notably, chicory root is well known as a source of polyphenols, compounds with recognized value in health improvement. In this study, we examined the physicochemical characteristics (TA, pH, and sensory evaluation) of bioactive yoghurt containing different concentrations of chicory. With increasing incubation time (5 h), the TA of the yoghurt increased whereas the pH decreased, regardless of the amount of chicory. As the amount of chicory increased, the scores for color, flavor, taste, and overall acceptability generally decreased. Among the tested groups, yoghurt with the addition of 1% chicory attained the highest scores. Further studies on the production of bioactive yogurt with optimum chicory concentration are needed.
