  • A study was made on the effect of anti-nutritional factors found in some Korean beans : soybean, red bead, mung bean and kidney bean. Two animal experiments were conducted to investigate the nutritional value of the beans. The first experiment, in which the diet contained 15% protein from raw beans, compared the intensity of inhibition caused by methionine deficiency or a total amino acid deficiency. In the second experiment, the conditions were the same as in experiment I, except that heated beans were substituted for raw beans. Severe growth inhibition and high mortality was found in the raw kidney bean and red bean groups than in the soybean and mung bean groups. As no effect on the growth inhibition of raw bean groups was shown by methionine and protein supplementation, the inhibition could be ascribed mainly to the low feed intake and the low protein digestibility caused by toxic factors. Pancreatic enlargement was obserbed in all the raw bean groups. A increase in body weight, a decrease in mortality and a decrease in the weight pancreases were found in the heated bean groups. But the digestility of the diet and of the protein and the PER by heating did not increase as markedly as weight, except in the heated red bean groups. Even with heat treatment, the whole inhibitory action could not be eliminated.

  • An auxin-producing bacteria, KSD16, KSD33, and KSD36 were isolated from agricultural soil. The strain KSD16, KSD33, and KSD36 was classified as a strain of Arthrobacter sp. based on phylogenetic analysis of 16S rRNA gene. The isolated KDS16, KDS33, and KSD36 was confirmed to produce indole-3-acetic acid (IAA), which is one of the auxin hormones. When the concentration of IAA was assessed the maximum concentration of IAA, 206.62 mg L-1, was detected from the culture broth incubated in R2A medium containing 0.1% L-tryptophan for 48 h at 28 ℃. To study the effect of IAA producing bacteria on germination rate, seeds of Mung bean were prepared for each treatment. KSD16, KSD33, and KSD36 showed significant increase in root length and number of adventitious roots than the controls. To investigate the growth-promoting effects on the crops, Arthrobacter species were placed in water cultures and seed pots of mung beans. In consequence, the seed germination of mung beans was 73.4% higher than the control.

  • Objectives : Many curative methods are used utilized in order to rid human body of disease when people become sick. Traditional Korean medicine generally prescribe methods that involve acupunture, moxibustion, or herb formulae. However, different types of foods are sometimes used as well. While wondering the history and efficacy of Qi-elevation foods that were consumed by Koreans in the past, the author discovered that a record from the Joseon Dynasty, called The Daily Record of Royal Secretariat of Joseon Dynasty, henceforth the Records, contained information about different types of porridge. Hence, the author looked through the records of porridge as written in the historical material in an attempt to learn the examples and efficacy of medicine-porridge consumed in Joseon's royal palace. Methods : After searching for the keyword, 'porridge', in the Records as provided by the National Institute of Korean History, the author extracted the porridges recorded during the Yeongjo period that each has its own special name. Results : Different types of porridge were recorded in the Records as following: arrowroot porridge, bean-leaf porridge, mung bean porridge, bean porridge, malt-rice porridge, oriental arborvitae seed porridge, crucian porridge, lotus seed porridge, adlay porridge, red bean porridge, welsh onion porridge, milk porridge, seashell porridge, ginko nut porridge, black sesame porridge, and mandarin porridge. Each porridge was used for the purpose of alleviating any disease that afflicted the king Yeongjo or his royal family members in relation with the ingredient herb's medicinal function. Conclusions : These porridges consumed by the king Yeongjo and his royal family members were used not only with a purpose of aiding their body's recovery from disease, but with the goal to actively curing them of ailments.

  • Studies were carried out to investigate formation of Mook and its physical properties as well as the effects of amylose and amylopectin on the texture of Mook which were made from cowpea, mung bean, acorn, buckwheat, kidney bean, potato, rice, corn and wheat starches. Texture parameters of 10% starch gels were significantly different depending on the kind of starches. However, there were no significant differences in those of gels of starches commonly used for the preparation of mook. It was appeared that gel indices of cowpea, mung bean, acorn and buckwheat starch gels were in the range of 2.11-2.37, elastic limits were more than 0.60, gel strength coefficients were in the range of 700-1400 and brittlnesses were 0.23-0.62. It was also appeared that gel index and elastic limit were affected by amylopectin and gel strength coefficient and brittleness, by amylose, and that these two fractions were not able to form gel like Mook unless they were combined with proper proportion. Effect of addition of amylose from cereal and potato starches to cowpea starch or cowpea amylopectin were different from that of cowpea amylose. When cereal starches were supplemented by cowpea starches, gel strength coefficients and brittlenesses of their gels were increased, but gel indices and elastic limits were not changed. However, potato starch gel was improved to be similar to Mook with increasing of gel strength coefficient and appearance of brittleness by addition of cowpea amylose.

  • Extrafloral nectaries have been shown in many studies to promote mutualistic interactions between plants and insects(usually ants) that visit the glands. The insects gain sugars, water and amino acids secreted by the extrafloral nectaries and benefit the plants by reducing the damage caused by plant's inseet herbivores. Little is known about the occurrence of extrafloral nectaries in plants growing in Asia. To learn about the occurrence of extrafloral nectary bearing plants in Korea, living plants and herbarium material were examined for the glands. In addition, the cover of plants with extrafloral nectaries and the proportion of woody plants with extrafloral nectaries were measured in three forest communities on Kangwha Island. 131 species of plants belonging to 53 genera and 30 families were found to have extrafloral nectaries. These 131 species comprise about 4.0% of Korea's flora, a highet percentage of extrafloral nectary bearing plants than occurs in the studied areas of North America. Extrafloral nectary bearing plants occupied 7, 23 and 55% of the covers and comprised 15, 21 and 15% of the woody plants in the three different forests, a significant level of occurrence. Many important Korean crop plants were found to have extrafloral nectaries including : sesame (Sesamum indicum L.), squash (Cucurbita moschata Duchesne), sweet potato (Ipomoea batatas Lam), persimmon (Diospyros kaki Thunb.) cotton (Gossypium indicum Lam.), mung bean (Phaseolus radiatus L.), red bean (Phaseolus angularis W.F.), peach (Prunus persica (L) Batsch.), plum (Prunus salicina Lindl.). Many of these cultivated and wild plants may receive protection by ants and other beneficial insects that visit their extrafloral nectaries.

  • Effect of plant hormones on the leaf senescence of mung bean (Phseoln radiatus) was investigated by measuring the changes of reducing sugar contents and invertase isozyme activities in detached leaves treated with NAA, $GA_3$ or BA. During dark-induced senescence, reducing sugar contents in the detached leaves increased temporarily at 4 6, thereafter decreased rapidly and reached minimum values within 7-14 6. The pattern of soluble acid invertase activity in the senescing leaves kept in the dark was similar to that of reducing sugar accumulation, whereas the activities of alkaline and extracellular invertases were not significantly changed during leaf senescence. Therefore, these results suggest that soluble acid invertase, but not alkaline and extracellular invertases, induces the accumulation of reducing sugar during leaf senescence of Rung bean plants. Exogenous NAA application had little or no effect In the increase of soluble acid invertase activity during dark-induced senescence compared to the control. However, exogenous applications of $GA_3$ and BA led to the increase of soluble acid invertase activity in the senescing leaves. Particularly, BA application was very effective In enhancing the activity of soluble acid invertase as well as in delaying chlorophyll breakdown during dark-induced senescence. These results suggest, therefore, that BA regulates the activity of soluble acid invertase, which leads to the accumulation of reducing sugar, and the stability of photosynthetic apparatus to delay leaf senescence.

  • This study performed microbiological hazards analysis in raw food materials, cooking processes, kitchen staff, utensils, and the environment in order to obtain contamination levels of S. aureus in school foodservice operations. S. aureus was not detected in cooked foods offered by the foodservice operations; however, it was found in raw food materials prior to cooking. In the case of vegetables, S. aureus was detected in washed mung bean sprouts, parboiled mung bean sprouts, and bellflower roots both before and after disinfection, at levels of 2.2, 1.0, 1.0, and 1.0 log CFU/g, respectively. For processed foods, S. aureus was detected in one sample of packaged bean curd as well as in mung bean jelly cake at the level of 1.5 log CFU/g. For meat products, S. aureus was detected in beef brisket and chicken at levels of 2.3 and 1.3 log CFU/g, respectively. To determine microbiological hazard data for the hands and gloves of cooking personnel, the staff members were divided into two groups: a group presenting Enterobacteriaceae or coliforms, and another group presenting neither Enterobacteriaceae nor coliforms. The results showed that S. aureus was detected on the hands of staff in each group at levels of 2.0 and 2.1 log CFU/hand, respectively, and at 1.8 and 0.0 log CFU/hand on the gloves of staff in each group, respectively. Among kitchen utensils, as an environmental factor in school foodservice operations, S. aureus was detected on meat knives, mixing bowls, and dish cloths at levels exceeding 1.0 log CFU/hand.

  • An examination of the kinetic properties of UDP-glucose, (1,3)-$\beta$-glucans (callose) synthase, from mung bean seedlings (Sorbus commixta cortex) shows that these enzymes have a complex relationship with UDP-glucose and various effectors. Fluorescence assay showed that deoxynojirimycin increased the inhibitory effect of (1,3)-$\beta$-glucan synthase in a concentration-dependent manner. The inhibitory effect of sakuranetin (34.34%) was higher than that of deoxynojirimycin (80.63%). Disk diffusion method revealed that sakuranetin inhibited the growth of Candida albicans to a 1.5 mm inhibition zone. These results suggest that sakuranetin, isolated from Sorbus commixta cortex extract, can be used as stable antifungal material.

  • The effects of adding mulberry leaves powder, yellow soybean powder(YSP), and mugwor powder(MP) for the preparation of mungbean starch gels(MSG) were studied. MSG with above additives were analysed for proximate composition. sensory evaluation, chromaticity, and rheometric properties. In the proximate composition test, the moisture content was the highest in the MSG with 0.5% MP, and the crude protein content war the highest in MSG with 1.0% YSP. In the sensory evaluation, MSG with various additives showed higher values than control. Whereas MSG with 0.5% additives showed a high value in hardness, control gels showed high values in the gumminess and brittleness in the measurement with a rheometer.
