Bacterial Distribution of Salt-Fermented Fishery Products in Seoul Garak Wholesale Market
Journal of Food Hygiene and Safety, volume 17, issue 4, 2002, Pages 173~177
It was performed to survey bacterial distribution on 72 salted fermented fishery products in Seoul Garak wholesale market from April to May in 2002. In average values of biological aspects, salts were 17.2%, in microbiological aspects (Unit: CFU/ml, bacterial cell count 4,900, coliforms 44, Vibrio spp., 160, Staphylococcus spp., 3,000 respectively. Of 93 isolated cells, coliforms were 35.5% (33/93), Vibrio spp. 8.6% (8/93) and Staphylococcus spp. 12.9% (12/93). E. cloacae was the highest (15/33) in coliforms, V. alinolyticus were the most (each 5/8) in Vibrio spp., In case of Staphylococcus spp., S. lentus was the best (5/12).
Studies on Heavy Metal Contamination of Agricultural Products, Soils and Irrigation Waters in Abandoned Mines
Journal of Food Hygiene and Safety, volume 17, issue 4, 2002, Pages 178~182
This study was conducted to estimate the status of heavy metal contamination in agricultural products (n = 280), soils (n = 280), and irrigation waters (n = 48) in abandoned mines & normal farm lands (n = 8). The samples were digested with acids, then analyzed fur the contents of lead (Pb), cadmium (Cd), copper (Cu), mercury (Hg), arsenic (As) and chrome (Cr) by an inductively coupled plasma spectrometer (ICP) and graphite- atomic absorption spectrophotometer (AAS). The contents of Hg were determined using a mercury analyzer. Abandoned mines had soils with higher contents of heavy metals except Cr and irrigation waters with higher heavy metals except Hg, compared to those of normal farmlands. The contents of heavy metals in agriculture products varied depending types of products. Agricultural products in abandoned mines generally showed with higher contents of heavy metals except Cu, compared to those of normal farmlands. There was no significant relationship in heavy metal contents between agricultural products and soils (p > 0.05). It is suggested that heavy metals of agricultural products and soils in abandoned mines should be continuously monitored.
Studies of Egg-Shell Calcium (I) - The Effects of Elution Condition of Egg-Shell Calcium on Elution Quantity and Ionization Rate -
Journal of Food Hygiene and Safety, volume 17, issue 4, 2002, Pages 183~187
This study was performed to investigate the utility of egg-shell calcium with calcium soak egg-shell in the vinegar. We compared examination eluted quantity with ionization rate in each condition. The results were as follows. 1 The degree of elution and ionization of calcium was proportional to the amount of vinegar and added acetic acid in the vinegar for elution. And ionization rate was the most high in case of 200 ml vinegar volume. 2. fluted quantity were increased in the rank order to 4
by temperature but the rank order of ionization of calcium was 3
by temperature. The occurrence of unacceptable flavor resulting from the immersion at 4
was another obstacle to adopt. 3. Eluted quantity and ionization rate of the egg-shell calcium were appeared excellent in case of the brewage vinegar at ventilation condition. The case of brown rice vinegar did not show a considerable difference, but eluted quantity and ionization rate were appeared the most excellent to the other sample. 4. The optimum condition for elution and ionization of the egg-shell calcium was appeared Immersing egg-shells in the brewed rice-bran vinegar at 3
for three days.
In vitro Screening of Natural Product Inhibitors on the UVB Phototoxicity
Journal of Food Hygiene and Safety, volume 17, issue 4, 2002, Pages 188~192
The phototoxicity inhibitory activity of 15 natural products having antiinflammatory effect was screened by three in vitro methods : yeast growth inhibition test with Candida albicans, RBC photohemolysis and MTT assay. We induced phototoxic reaction by irradiating UVB (312 nm) on chlorpromazine (CPZ) that has been widely documented as phototoxic agent in clinical and experimental studies and then observed the effects of the natural products after treating them with CPZ. In yeast growth Inhibition test, P. persica and E. officinalis showed the inhibitory effect on the UVB phototoxicity and E. officinalis, yeast, P. suffruticosa showed phototoxicity inhibitory effect in that their ％ hemolysis compared with control were 45.76
4.76 on UVB. In MTT assay, all tested natural products increased cell viability compared with the contort.
Effect of Cochlodinium polykrikoides Bloom on the Quality Changes of Fish during Storage in Seawater
Journal of Food Hygiene and Safety, volume 17, issue 4, 2002, Pages 193~200
Three species of fish such as yellow tail (Seriola quinqueradiata), bastard halibut (Paralichthys olivaceus) and black rockfish (Sebastes schlegeli) were exposed to the dinoflagellate, Cochlodinium polykrikoides, and quality changes of fish after death were investigated during the extended storage. The volatile basic nitrogen (VBN) and aerobic plate counts (APC) were determined in the muscles of fish, arid organoleptic change was evaluated in the kills, skins and muscles. APC in all the fish species did not change in 6 hours of storage, but increased gradually thereafter. VBN contents in the muscles continuously increased throughout the storage of fish. Slightly higher levels of APC and VBN were observed in the tested fish than control fish, which had been exposed to air until died and stored in seawater without treating C. polykrikoides. After 12 hours of storage, APC and VBN contents in the muscles did not exceed the initial spoilage limit, 10
CFU/g fur APC and 30 mg/100 g for VBN, in all of the fish including control fish. Organoleptic change in fish treated with C. polykrikoides did not greatly differ from the control fish. After 8 hours of storage, distinctive deterioration of muscle was detected organoleptically in the treated fish and the control fish. The compiled result indicated that moribund fish exposed to C. polykrikoides bloom should be handled properly in 6 hours of storage after death of fish.
Effect of Kumquat on N-nitrosodimethylamine Formation
Journal of Food Hygiene and Safety, volume 17, issue 4, 2002, Pages 201~205
When it added to each designed diet groups such as control, nitrate rich, amine rich and nitrate-amine rich diet under simulated gastric conditions, effect of kumquat (Fortunella mararita) juice on formation of N-nitrosodimethylamine (NDMA) was studied. Inhibition on NDMA formation was the highest in the amine rich diet, as 69.4
2.4%, when the juice of 10m1 added to its digestate. Phenolic portion of
sep-pak cartridge in kumquat juice were separated into 20 kinds of a phenolic compounds using HPLC. These phenolic fractions such as faction no. 1, 2, 3, 4 and 5 inhibited from 3.0
1.2% to 66.5
2.0% NDMA formation in the reaction system which was mixture of nitrite and dimethylamine.

Journal of Food Hygiene and Safety, volume 17, issue 4, 2002, Pages 206~209
From February through March 2002, sixteen rockfishes representing three species were collected from Oregon Coast Aquarium and Newport fish market and examined far nematodes. During this study, a total of 157 Anisakis type larvae were recovered from Sebastes spp. and parasitized for an average infection prevalence of 50.0%. The yellowtail rockfish, S. flavidus, darkblotched rockfish, S. crameri, and canary rockfish, S. pinniger examined were infected with 110 Anisakis simplex larva, 30 Contracaecum spp. larva and 17 Pseudoterranova decipiens larva. Of the rockfishes examined, 75.0% carried Sebastes crameri, and 12.5% S. flavidus and S. crameri, respectively. The sites of infection far Anisakis type larvae were the intestine, omentum, and stomach walls. A. simplex larvae infected 60.0% on S. crameri and 33.3% on S.flavidus and S. pinniger respectively. The prevalence of Contracaecum sp. larvae and Pseudoterranova decipiens larvae on S. pinniger was 33.3%. The intensities of A. simplex larvae ranged from 1 to 87 in S. flavidus, S. crameri, and S. pinniger. The intensity of Contracaecum spp. larvae and P. decipiens larvae ranged from 0 to 30 in S. pinniger.
Antidiabetic Effect of Cordyceps militaris and Paecilomyces japonicus in Streptozotocin-induced Diabetic Rats
Journal of Food Hygiene and Safety, volume 17, issue 4, 2002, Pages 210~215
To elucidate the effect of water and methanol extracts of Cordyceps militaris, Paecilomyces japonicus and their mycelin on diabetes and organs in STZ-induced diabetic rats, weight of organs (liver, kidney, spleen, thymus), plasma level of blood glucose, total protein, triglyceride, free fatty acid, hepatic total protein, triglyceride and glycogen were determined as compared with those of negative control group. The blood glucose level of CM-1 and CM-M group showed significantly reduced, and all groups except CM-2 increased in body weight. CM-1 decreased the liver weight, and PJ-2 decreased the kidney weight. In all groups except PJ-2, plasma total protein level was increased, and the triglyceride, and CM-3 and CM-H decreased the free fatty acid was decreased in CM-3, PJ-1 and PJ-2 treated groups. In hepatic tissue, total protein was significantly increased in CM-H and CM-M treated group, and in all groups except CM-2, the triglyceride were significantly decreased and glycogen was increased. In conclusion, CM-1 and CM-M that possess potential antidiabetic activity increased glycogen and lowered serum glucose level, thus they might improve metabolic disorder originated from diabetes by increasing serum protein and reducing excess triglyceride in serum and liver tissue.
