  • A study was carried out to determine the influence of climatic environments on the growth characteristics and bulb quality of extremely early-maturing type onion grown at different altitudes, such as 60m, 200m, 350m and 700m above sea level (ASL). The mean air temperature during the growing season of extremely early-maturing type onion (October 18 to April 27) was $10.8^{\circ}C$, $9.6^{\circ}C$, $8.1^{\circ}C$ and $6.1^{\circ}C$ at 60m, 200m, 350m and 700m ASL. The mean air temperature during the bulb growth period (March 16 to April 14) was recorded $10.5^{\circ}C$, $9.4^{\circ}C$, $7.9^{\circ}C$ and $6.0^{\circ}C$ at 60m, 200m, 350m and 700 m ASL. Plant height, neck diameter, leaf number, leaf area, top fresh weight and top dry weight were significantly increased in growing of extremely early-maturing type onion at 60m ASL. Bulb/neck diameter ratio increased rapidly under the same temperature regime. The diameter and weight of the bulb were also the largest at 60m ASL during the bulb growth period (daily mean temperature of $12.5^{\circ}C$). At 60m ASL, there was the highest bulb size like a height, diameter and weight of bulb related directly on onion yield in the bulb growth period from March 16 to April 14. In contrast, yield and bulb quality were considerably decreased at 700m ASL during the bulb growth stage (daily mean temperature of $8.4^{\circ}C$). The quantity of extremely early-maturing type onion has gradually decreased as the daily average temperature drops below $12.5^{\circ}C$ during the bulb growth stage (March 16 to April 14). As a result, the lower temperature (daily mean temperature below $12.5^{\circ}C$) during the bulb growth stage significantly decreased the size and quantity of bulb in direction proportion.

  • Crude extracts of 4 Allium SPP. such as welsh onion, onion, chinese chives and garlic were purified by paper chromatography and these activities were bio-assayed with rice seedlings. The stem and leaf slices of Allium spp. were treated and rice seedlings were planted in the soil to know the effect of its application on rice growth. The weak acidic fraction of Allium SPP. enhanced the growth and rooting of rice seedlings and had greater activity in promoting than in inhibiting the growth on rice seedling. Elongation of the second leaf sheath of the rice seedlings were not influenced by the extracts of Allium SPP. The stem and leaf application 10 days before transplanting, increased the number of effective tiller remarkably. Especially, the application of 50~400g welsh onion and 50~200g onions increased the number of spikelets per panicle compared to standard fertilization. But, in application of larger amounts, the-death rate of the rice seedlings after transplanting was higher in the stem and leaf application 10 days before transplanting than the one applied on the transplanting day. In particular, treatments of chinese chives and garlic showed higher death rate than those of welsh onion or onion. The stem and leaf application of Allium SPP. resulted in high yield than standard fertilization.

  • This study was carried out to access the stauts of pyruvic acid and sugars in onion bulbs during storage at room temperature. Pyruvic acid content remained in a steady state until 3 months of storage. However the pyruvic acid content gradually increased as the onions started to root, and rapidly increased after sprouting. There was no difference in dry matter contents during storage.e. Sucrose content increased as storage duration extended, and then gradually decreased right after the onions started to sprout. Fructose content gradually decreased after 45 days of storage, and remained in a steady state after sprouting. Glucose content had a tendency to increase as storage duration extended. Pyruvic acid/total sugar (PA/TS) ratio decreased after 1 month of storage, and then increased after 135 days, and was 83% higher at 150 days of storage than at harvest. Sweetness gradually decreased until 1 month of storage, but thereafter remained steady. Therefore it is desirable that pyruvic acid analysis for sweet onion selection should be conducted before breaking the dormancy.

  • In 1998, a pathogen isolated from infected onions was identified as Aspergillus niger. At 3$0^{\circ}C$, A. niger AnYD-1 showed the best mycelial growth, spore germination, and high pathogenicity to onions. In spite of the weak inhibitory effect of flusilazole and hexaconazole on the mycelial growth on PDA, they showed the specific inhibitory activity against the formation of spores in the vapour phase. With flusilazole and hexaconazole, the effects of the solvent, the applied concentration and the incubating temperature on the activities inhibiting the spore formation were confirmed. Their inhibitory effect on the spore formation in vapour phase was excellent by solving them with dimethylsulfoxide and dimethylformamide among tested solvents, and applying them at high temperature such as 30~35$^{\circ}C$.

  • To prevent the caking of powdered onions, various anticaking agents were evaluated. Effects of pre-treatment and post-treatment with anticaking agents on the degree of caking were investigated. Among various antiagglomerants corn starch and waxy corn starch were selected. The degree of caking with various particle sizes of $30{\sim}50$ mesh, $50{\sim}80$ mesh and $80{\sim}200$ mesh was determined. As a result post-treatment and post-treatment after pre-treatment showed more effective than the pre-treatment with 6% corn starch or 6% waxy corn starch suspension added to 1% soluble starch solution. Waxy corn starch was relatively more effective in preventing caking than corn starch according to the type of starch used. Powdered onions with corn starch as an anticaking agent were considered as additives of various starch-based foods.

  • The purpose of this study was to analyze the microbiological hazards of prepared foods, raw materials, utensils and workers' hands and to evaluate cross-contamination of bacteria in foodservice establishments. Aerobic plate counts, coliforms, E. coli, E. coli O157:H7, Salmonella spp., Staphylococcus aureus and Listeria monocytogenes were tested. According to the microbiological evaluation, there were many cases of contamination of bacteria. Staphylococcus aureus was detected in chicken stew (Korean type), Japchae, Bibimbap and Kongnamul-muchim at the A foodservice establishment and Jwieochae-jorim at the B foodservice establishment. E. coli was detected in Ojingeochae-muchim at the C foodservice establishment. E. coli O157:H7, Salmonella spp. and Listeria monocytogenes were not detected in any of the tested samples. Critically, microbiological contamination of raw materials, utensils and workers' hands could result in contamination of prepared foods, thus, attention needs to be given to sanitation of raw materials, workers' hands and utensils to reduce or eliminate contamination of bacteria.

  • These experiments were carried out to study the factors affecting quality and textural characteristics in the preparation of artificial gluten meat (AGM). These results were compared with the raw beef on its properties. Effects of amounts of ingredients on properties of AGM were summarized as follows: 1. On effects of amounts of ingredients, walnut was one of the most factors on the color in AGM The more increased the amounts of walnut, the more decreased hardness, cohesiveness, chewiness, and the more increased springiness and water holding capacity. Therefore, the 30% of walnut added sample became similar to raw beef. 2. The kinds and amounts of oil and mixing methods did not affect on color, shear force, and chewiness, but did on cohesiveness significantly 3. The more increased the salt levels, the better were the hardness and chewiness, but shear force and water holding capacity were not affected. 2% of salt added sample approached to raw beef in hardness, springiness, cohesiveness and chewiness. 4. The more onion levels increased, the more hardness and chewiness decreased.

  • The effect of several hydrocolloids on the rheological behavior of wheat flour was investigated. The influence of the selected hydrocolloids (alginate, carrageenan, CMC, guar, locustbean and xanthan) on wheat flour was tested by using two different techniques; amylograph and texture analyzer. In order to have a general overview of their effects hydrocolloids were chosen from different sources implying a broad diversity of chemical structures. The hydrocolloid addition decreased the brightness(L) but increased yellowness(b). The interaction between hydrocolloid and flour produces a slight modification of the amylogram parameters, being the most clearly affected parameter breakdown, which is increased by carrageenan, guar and xanthan. Hardness and cutting force were augmented by hydrocolloid addition, while springeness was decreased except guar and locustbean. In summary, when looking for the improvement of the noodle texture, guar, locustbean are the best candidate additives due to their effects on pasting and texture properties. These hydrocolloids increase the hardness, cutting force, gumness, chew-ness, so were thought to increase the eating quality. So, each tested hydrocolloid affected in a different way the rheological properties of wheat flour, the results obtained are important for the appropriate use of these hydrocolloid as ingredients in the noodle making process.

  • This study was conducted to assess the effect of highly concentrated onion intake on rodents. The experimental animals were divided two groups as follows; water administered group (CON) and Allium cepa administered group (ACE). The ACE group showed a slightly increases in the number of erythrocytes (RBC), hemoglobin (HGB), hematocrit (Hct) levels compared to the control group (p<0.05). Hemoglobin, monocyte, lymphocyte and neutrophil had no significant change (p>0.05) in ACE group and control group. The analysis of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) levels showed a significant decrease in ACE group compared to the control group (p<0.05). The blood glucose, total protein, HDL-cholesterol were slightly high in ACE group, while triglyceride, total cholesterol levels were lower in ACE group compared to the control group (p<0.05). The levels of cytokines (interluekin-1α (IL-1α), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), interferon-γ (INF-γ), interleukin-18 (IL-18), interleukin-2 (IL-2), granulocyte-macrophage colony-stimulating factor (GM-CSF)) involved in immunity and inflammation in liver tissue and blood have all been confirmed to be within normal range. These findings could be used as basic data to show that highly concentrated dietary onion extract is not toxic to hematological indicators and immune functions.
