당뇨병은 질병 치료와 관리에 있어서 적절한 식이요법이 필수적이며 식이성분이 매우 중요한 역할을 하는 것으로 알려져 있다. 치커리 이눌린은 인체 내 소화효소에 의해 가수분해되지 않는 수용성 식이섬유원이며 올리고당은 생체 내에서 천연 식이섬유질과 유사한 역할을 할 뿐만 아니라 소장내에서 소화 흡수되지 않는다. 이에 따라 대장의 유익한 장내 미생물인 비피더스균에 의해 일차적으로 이용되어 유기산을 생산하여 장질환을 예방하고, 지질대사를 개선하는 등 건강기능식품으로 이용가치가 높은 식품으로 평가되어지고 있다. (중략)

치커리는 서구 유럽에서 중요한 서양 채소이다. 현재 국내에서는 커피대용으로 뿌리를 이용하는 치커리를 일부 지역에서 재배하고 있을 뿐, 아직 잎을 이용하는 샐러드용으로는 보급이 많이 이루어지고 있지 않다. 그러나 앞으로 각광받을 엽채류로서 이에 본 실험은 수경재배를 통한 주년생산을 하기 위한 기초 연구로서 몇가지 치커리 품종에 대한 적정 배양액 농도를 결정하기 위해 수행하였다. (중략)

초식가축에 대한 탄닌의 이용성을 조사하기 위하여 소 반추위에 cannula를 설치하여 Lotus pedunculatus와 chicory를 넣어 시간별 condensed tannin의 변화를 조사하였다. 제 4위와 소장 내에서의 변화를 조사하기 위하여 제 1위에서 처리된 시료를 pH 4와 8에서 각각 처리하여 탄닌에 의한 단백질 이용성 증진효과를 보았다.(중략)

The experiment was conducted to establish the blanching culture of chicon expected to become exporting crop, for preventing Korea fiom importing the ffreign chicon and increasing the growers' profits, the days of blanching culture are based on the 5 treatments such as 10 days, 15 days ,20 days, 25 days, and 30 days. In the blanching culture days of chicory, the growth was good as blanching culture days were longer, there were too many outer leaves, and the ratio of bolting was $16\%$ on the 25 days, $30\%$ on the 30days. On the 10th day, the weight of chicon was light, the hardness was low, the density was low. The quality of chicon had no differences among the treatments. Therefore, the optimal condition for blanching culture of chicory is that the days of blanching culture is 20 days.

Chicons are kinds of sprout vegetables which forced from the roots of chicory (Cichorium intybus L.). Experiments were performed to investigate the proper cultivation period and region of chicories which are 3 different cultivars for improving storability of chicon. The fresh weight of chicon packed with 20 ${\mu}m$ LDPE film decreased less than 0.5% during the storage at $10^{\circ}C$ in all treatments, and Chuncheon region treatment and 'Focus' cultivar treatment showed higher fresh weight loss than the others. And it decreased higher, as the cultivation periods was longer. The oxygen content in film was from 8% to 17% during storage at $10^{\circ}C$. There was not any significantly different oxygen content among cultivar treatments and cultivation region treatments, but 100 days' cultivation period treatment showed the highest content than the others. The carbon dioxide content in film showed around 3% during storage at $10^{\circ}C$. It also did not influenced by cultivars and cultivation regions, but 100 days' cultivation period treatment showed the lowest content than the others. The ethylene content in film was changed dramatically from 2 to 14 ${\mu}l{\cdot}l^{-1}$, and it showed around 8 ${\mu}l{\cdot}l^{-1}$ as approaching to 21 days after storage at $10^{\circ}C$. The visual quality of chicon deteriorated below marketability level from 12 days after storage at $10^{\circ}C$, and that of 'Metafora' cultivars decreased the highest. That of Pyeongchang region treatment was kept higher, and 'Vintor' cultivar treatment showed highest visual quality than the others which were grown in Pyeongchang region. The firmness of chicon increased, as the cultivation period was longer regardless of cutlivars and cultivation regions. The russet spotting that is ethylene injury symptom of chicon appeared at the latter term of storage and was higher in Chuncheon region treatment. Conculsionally, chicory that is for producing chicon should be grown more than 120 days in Kangwon region and grown in high-land region like Pyeongchang to improve the storability of chicon.

This study was conducted to compare the storability of 6 chicory cultivars for producing chicon; 'Vintor', 'Focus', 'Metafora', 'Kibora', 'Nobus', and 'Redoria Red' grown in 2 regions: Chuncheon (plain region) and Pyeongchang (high land region). Chicons were produced from chicory roots that grown for 120days and then stored for over 120days at $2^{\circ}C$ and 90% of RH conditions. To produce chicon, chicory root was forced at $18^{\circ}C$ for 22days with suppling the nutrient solution ($KNO_30.54g{\cdot}L^{-1}$, $Ca(NO_3)_2\;1.02g{\cdot}L^{-1}$, $MgSO_4\;0.36g{\cdot}L^{-1}$, $KH_2PO_4\;0.21g{\cdot}L^{-1}$, $K_2SO_4\;0.10g{\cdot}L^{-1}$, pH 7.0). Chicons produced from 6 different chicory cultivars packed with $25{\mu}m$ ceramic film and stored for 25days at $8^{\circ}C$. The fresh weight of chicon in MAP was maintained to 99.5% of pre-storage weight. The fresh weight of 'Redoria Red' was lowest in all cultivars, and that of Chuncheon region cultivated treatment was lower than Pyeongchang treatment. The $CO_2$ and $O_2$ concentration in chicon MAP were 2% and $10{\sim}17%$. There were not significantly different among cultivars and between regions, although 'Redoria Red' cultivar showed highest $CO_2$ and lowest $O_2$ concentrations. The ethylene concentration in chicon MAP was $1.0{\mu}{\iota}{\cdot}{\iota}^{-1}$ and also didn't show any significant difference among all treatments. Chicon detoriorated visual quality with appearing russet spotting that result from ethylene gas. The visual quality of 'Redoria Red' cultivar decreased faster than the other cultivars. 'Metafora', 'Focus', and 'Kibora' maintained higher firmness of their leaf than the others, and the firmness was higher grown in Pyeongchang region cultivated treatments than in Chuncheon region.

Phytophthora root rot of lettuce, which has not been reported in Korea before, occurred severely in liquid hydroponic culture. The disease occurred in all seasons and was most severe in summer from June to August, showing over 90% infection rate in some farms. A total of 51 isolates collected from various farms were all identified as Phytophthora drechsleri. The fungus showed strong pathogenicity to lettuce and Chinese cabbage, moderate pathogenicity to cucurbits and tomato, and weak pathogenicity to pepper. However, the fungus was not pathogenic to other leafy vegetables namely: chicory, kale, endive, garland chrysanthemum, spinach beet, and perilla. Among 10 species of Phytophtora inoculated to lettuce, only P. drechsleri and P. cryptogea were found pathogenic.

This reserch was carried out to investigate the nitrite scavenging abilities (NSA) of 7 kinds of tea extracts. Nitrites are used as additives of cured meat preperation and exist in plants, foods, and medicines, so we intake it very often easily. Nitrites can act with amines to produce nitrosamine which is known to be a carcinogen. It is known that the pH, concentration of amines, and amounts of nitrite are three important conditions of nitrosamine occurence. 7 kinds of tea used in this experiment were Persimmon tree (Diospyroo kaki Thiunb, Per.), Mulberry tree (Morus alba Linne, Mul.), Rubber tree (eucommia ulmoi-des Oliver, Rub.), Solomon's-seal (Bolygonatu Morr, Som.), Chicory (Cichorrium intybus L, Chi.), Sumach (Rhus javanica L., Sum.), Docwood (Cornus officinale Sieb, Doc.) and they were extracted with methanol (MeOH), ethyl ether (EtEt), ethyl acetate (EtAc), and also the extract existed in the aqueous layer II (Aq L. II) was used.
