Effects of addition of Chinese chives into frozen noodle on retrogradation of the cooked frozen noodle were examined by enzymatic evaluation during the storage 3 days at $4^{\circ}C$. The retrogradation rate during storage was significantly reduced by addition Chinese chives. Thus we hypothesized that retarogardation and textural changes of frozen noodle might be linked to thermostable amylase in Chinese chives. The amylase isolated from Chinese chives was affected by temperature and pH of buffer used. The enzyme was mainly extracted 20 mM potassium phosphate buffer(pH 7.0). The enzyme was extremly stable at wide temerature and pH. Amylase activity was maximal at $50^{\circ}C$ and pH 7.5. The enzyme was not inactivated by heat treatment at $70^{\circ}C$, $80^{\circ}C$ for 30 min. We suggest the enzyme was stable at high temperature. To investigate the effect of different storage packge on texture properties, color, sensory evaluation, parent-packged and unparent packaged frozen noodle was compared with control. As the storage passed, the frozen noodle packaged with parent showed a rapid decrease in the color. The hardness was gradually decreased during storage. It was found that unparent packged must be nessasry in the Chinese chives frozen noodle. In changes of sensory properties by traind panel, Chinese chives frozen noodle with 2% blanched Chinese chives got the highest score in overall acceptability, therefore we tried acceptance test by consumers with 2% blanched frozen Chinese chives noodle.

This study was conducted to investigate the efficacy of freshwater alga, Chlorella fusca on the improvement of growth and qualities in organic spinach and Chinese chives farm. The average height of Chinese chives treated with the chlorella was 3.7 cm smaller than that of the untreated. The leaf width and fresh weight of Chinese chives treated with the chlorella was 0.5 mm wider and 30.3 g heavier than that of the untreated. The commercialization and yield of Chinese chives treated with the chlorella was 11.9% and 18.3%, respectively higher than that of the untreated. Also, the disease severity of gray mold disease of Chinese chives treated with the chlorella was reduced by more than 24.2% when compared with the untreated. The thickness and number of spinach leaves treated with chlorella was 27.9% and 41.8%, respectively higher than that of the untreated. The fresh weight and yield of the spinach treated with the chlorella was 63.6% and 31.5%, respectively higher than that of the untreated. Moreover, the mineral content of K, Ca, Mg, P, Fe, and Mn were recorded higher in the spinach treated with chlorella compared with that of untreated. The results indicated that the freshwater alga, Chlorella fusca is efficient and economical biostimulant in improving plant growth and quality of Chinese chives and spinach in organic farm.

During the storage period of chives(Allium Tubersum fouler) at low temperature(4-5$^{\circ}C$), weight loss in chives by the packages of LDPE, p.p and HDPE film was decreased less than 1%, however that of chives unpacked was remarkably increased as time went by. Soluble solids of unpacked chives was decreased from 6.0 to 4.6 $^{\circ}$Brix after 2 weeks storage and that of LDPE film sealed was lessened to 4.9-5.9 $^{\circ}$Brix, the treatment of deaeration showed a tendency to decrease a lot to 4.5-4.7 $^{\circ}$Brix. The vitamin C content of chives unpacked was 37.1mg% at before storage, but after one week decreased very much to 15.2mg%, and that in chives packed by the different methods was visibly lessened after 2 weeks storage. the Vitamin C content in chives processed by deaeration sealing method was lessened compared to that at chives processed by sealing only. In the bag of chives packed by HDPE film had low CO$_2$ and C$_2$H$_4$ concentration and the gas concentration in the bag of chives processed by P.P. film was increased as storage period went by. Conclusively the freshness of chives packaged by LDPE and HDPE film maintained for 3 weeks, at P.P film for 2 weeks, but the marketability of chives unpacked was degraded in 3-4 days.

The Korea chinese chives are a major edible vegetable and they are traditionally been used as a folk medicine. However recently studies on the Allium tuberosum are mainly on the morphological property and the chemical constituent. There are no reports concerning hematological changes in dogs administrated ethyl acetate extracts of Korea chinese chive. This experiment was conducted to investigate the hematological changes in dogs administrated ethyl acetate extracts of the Korea chinese chives($5m{\ell}/mg$) for 6 days. During administration blood samples were collected at 3h, 6h, 12h and then on daily basis until day 6. Blood samples were analyzed red blood cell(RBC), packed cell volume(PCV), hemoglobin concentration(Hb), mean corpuscular volume(MCV), mean corpuscularl hemoglobin concentration(MCHC), reduced glutathion(GSH), and met-hemoglobin concentration. The RBC count was significantly(p<0.01, p<0.05) decreased during experimental periods. Packed cell volume, hemoglobin concentration were not showed significantly difference during experimental periods. The MCV was significantly(p<0.01, p<0.05) increased from 3 hours after administration to day 4. The MCHC was significantly(p<0.05)decreased on day 6. GSH concentration was not showed significant difference during experimental periods and the met-hemoglobin concentration was significantly(p<0.05) increased on day 3.

This study was conducted to find out the effects of crude extracts from welsh onion, onion, chinese chives and garlic on the seedling growth of chrysanthemum, lettuce, rice, radish, chinese cabbage, cucumber and oriental melon. The crude extracts from Allium spp. inhibited the growth of chrysanthemum and lettuceseedlings at low concentration, the effect increased as the concentration grew higher, and especially in lettuce, the radicle growth was inhibited greater than the hypocotyl growth.The root extracts from welsh onion, chinese chives, and stem-leaf extracts from welsh onion, chinese chives and garlic significantly promoted the root growth of rice seedlings at 300∼700ppm and at 500∼1,000ppm, respectively, and the leaf sheath was elongated at low concentration of all extracts. The stem-leaf extracts from garlic and onion promoted the root and hypocotyl growth of chinese cabbage up to 2,000ppm or 3,000ppm. Root extracts from all Allium spp. promoted the elongation of chinese cabbage root up to 300∼700ppm, but they didn't influence its hypocotyl elongation. At low concentration of onion, garlic and chinese chives extracts, the growth of radish seedlings was highly promoted. The promotive effect, however, declined as the concentration increased. Only, extracts of chinese chives promoted the growth of radish seedling up to 5,000ppm. The stem-leaf extracts from onion and garlic promoted hypocotyl growth in pepper, up to 5,000ppm, but had little effect on other treatments. All of the extracts markedly promoted both root(main and lateral root) and hypocotyl growth in cucumber seedlings. A higher degree of promotion was made in the cucumber lateral root by onion and garlic extracts. The seedling growth of oriental melon was slightly increased by low concentration, but high concentration inhibited the root and hypocotyl growth.

The objective of this study was to investigate the contents of some minerals in vegetable foods by a highly sensitive Neutron Activation Analysis. Chinese Chives, Amaranth, Mugwort, Ginger, Garlic, Root of bellflower, Cultured Duduk, Wild Duduk and Cortinellus-edodes were chosen as experimental materials for this study. The contents of potassium, copper, molybdenum, and bromum were 7099.1mg%, 104.8 ppm, 45.4ppm and 40.4ppm in Chinese Chives. Chinese Chives, Amaranth and Mugwort were more abundant with iron, coppr and cobalt other than vegetable foods. The ratio of sodium to potassium for Chinese Chives was 1 to 796, for Mugwort : 1 to 147 and for Garlic : 1 to 148. As the Neutron Activation Analysis Technique was able to detect gold, samarium, bromum, lanthanum and scandium from vegetable foods, this technique is very useful to analyse the infinitestimal elements in foods.

To investigate the long term effect of buchu (Chinese chives) diet on ROS formation in the liver and stin tissue of ICR mice, one of control, 2% or 5% buchu-added diet was fed to ICR mice for 12 months. Superoxide anion (O2ㆍ), hydrogen peroxide($H_2O$$_2$) and hydroxyl radical (ㆍOH) contents were measured in cytosol, microsome, mitochondria of liver and skin of mice, respectively. Behu diet showed a significant decrease of superoxide anion, hydrogen peroxide and hydroxyl radical contents in liver and skin tissues compared to control diet, and this effect is especially higer at 5% than at 2% buchu diet level. ICR mice showed an age-dependent increase in ROS contents, while the group fed buchu diet decreased its ROS contents significantly and ROS contents of liver appeared to be 2 fold higher than skin. The results of the present study suggest that antioxidative components and sulfur-compounds in buchu diet appear to be responsible for the inhibition of ROS formation in ICR mice.

Chinese chive (Allium tuberosum Rottler) has potential risks associated with pathogenic bacterial contamination as it is usually consumed raw. In this study, we investigated the microbiota of Chinese chives purchased from traditional markets and grocery stores in March (Spring) and June (Summer) 2017. Differences in bacterial diversity were observed, and the microbial composition varied across sampling times and sites. In June, potential pathogenic genera, such as Escherichia, Enterobacter, and Pantoea, accounted for a high proportion of the microbiota in samples purchased from the traditional market. A large number of pathogenic bacteria (Acinetobacter lwoffii, Bacillus cereus, Klebsiella pneumoniae, and Serratia marcescens) were detected in the June samples at a relatively high rate. In addition, the influence of the washing treatment on Chinese chive microbiota was analyzed. After storage at 26℃, the washing treatment accelerated the growth of enterohemorrhagic Escherichia coli (EHEC) because it caused dynamic shifts in Chinese chive indigenous microbiota. These results expand our knowledge of the microbiota in Chinese chives and provide data for the prediction and prevention of food-borne illnesses.

Tip burn has been reported as one of the most serious physiological disorder in Chinese chives (Allium tuberosum Rottl.) cultivated in plastic film house. In this study, a physiography and chemical properties of 132 plastic film house soils were investigated to elucidate factors affecting tip burn symptom. Also influence of soil properties on tip burn was statistically determined by path analysis and association analysis including a chi-square test or logistics analysis. Probability distribution of inorganic aqueous species, such as ammonia (g) was calculated using MINTEQ program. Soil order and chemical properties, especially pH, exchangeable calcium and inorganic nitrogen, showed a significant relationship with tip burn of Chinese chives. Tip burn symptoms occur mainly in an alkaline soil classified as Alfisols. Result of linear regression and path analysis exhibited that formation of ammonia (g) from soil solution depend upon soil pH and were associated with ammonium resulting from soil organic matter or nitrate. These results indicate that tip burn symptom of Chinese chives is directly affected by ammonia gas originated from alkaline soil condition.
