Hygienic Studies on Agricultural Products in Yungnam District (part I) Isolation of Aflactoxin producing Strains
;;;;James J. Pestka;
Journal of Food Hygiene and Safety, volume 4, issue 3, 1989, Pages 165~170
To isolate the aflatoxin producing strains from agricultural products in Youngnam districts, rice(59), meju(30), corn(32), barley(58), soil(33), peanut(30), soybean(45), and unhulled barley(60) were collected from markets or homes. From 342 sample sources, 280 strains of Aspergillus spp. were isolated. As a result of screening by TLC, 29 strains expressed fluorescent spot and four strains have a same Rf value of standard aflatoxins, and the percentage of contamination from aflatoxin producing strains was 1.3%, and those strains were estimated as Aspergillus flavus group by the examine of characteristics and morphology.
Hygienic Studies on the Agricultural Products in Youngnam Districts (Part II) Determination of Aflatoxin B1 by ELISA Method

Journal of Food Hygiene and Safety, volume 4, issue 3, 1989, Pages 171~176
A rapid, simple method of ELISA was applied for the determination of aflatoxin BI in cereals from Y oungnam districts. Antibodies obtained cross reacted with aflatoxin B2 and to a less extent with other aflatoxin BI analogs. Response range for a typical standard curve was between I and 100 ppb. Fewer interference by spiked methanol-PBSdimethylformamide extracts ofrice was evidenced. Contents of aflatoxin BI from rice (65) and barley (116) were determined by competitive direct enzyme- linked immunosorbent assay as follows. Three out of 65 rices samples were positive. Rice samples of R-IS, R-30, and R-59 represent the aflatoxin B1 levels of
, respectively, and showed 4.6% aflatoxin BI contamination in rice samples. Meanwhile, four out of 116 barley samples were positive. VB-37 showed the highest aflatoxin Bllevels of
and VB-35, VB-15 and VB-54 represent
, respectively, and showed 3.4% aflatoxin B1 contamination in barley samples.
Hygienic Studies on Agricultural Products in Youngnam districts (Part III) On the contents of Inorganic Compound
Journal of Food Hygiene and Safety, volume 4, issue 3, 1989, Pages 177~184
Contents of inorganic compounds in various cereals (Rice: 62, Barley: 39, Soybean: 58, Unhulled barley: 59) collected from Youngnam Districts in 1989 were determined by the atomic absorption spectophotometer. The results abtained as follows: The ranges of zinc level in rice, barley, soybean and unhulled barley were 46.91-76.28 ppm, 42.24-77.06 ppm, 73.39-103.69 ppm and 48.08-272.49 ppm, and those of manganes in each samples were 4.96-14.75 ppm, 20.62-16.28 ppm, 23.31-42.488 ppm and 23.52-30.15 ppm respectively. The ranges of iron level in rice, barley, soybean and unhulled barley were 65.38-141.33 ppm, 52.22-133.25 ppm, 106.32-240.20 ppm and 66.44-108.64 ppm, and those of calcium in each samples were 10.25-33.67 ppm, 68.94-136.62 ppm, 492.20-967.84 ppm and 75.30-165.85 ppm respectively. Meanwhile, contents of sodium in rice, barley, soybean and unhulled barley were 291.60-453.60 ppm, 462.25-773.60 ppm, 463.83-792.67 ppm and 777.90-950.90 ppm and those of potassium in above samples were 716.00-1180.60 ppm, 1363.60-1686.00 ppm, 2233.84-2792.67 ppm and 2042.10-2141.46 ppm respectively.

Analysis of Pungent Principles of Capsicum Fruit by HPLC
Journal of Food Hygiene and Safety, volume 4, issue 3, 1989, Pages 191~198
The analysis condition for determination of capsaicin and dihydrocapsaicin, major pungent principles of capsicum fruit, with high performance liquid chromatography was studied and the difference of those content according to species, cultivated region and drying method was investigated. The capsaicins were extracted effectively with 70% ethanol for 1 hr at
. As a result of reproduciblity and recovery test, the calculation of analysis data was reasonable based on the peak area. The content of capsaicins was different with species, cultivated region and drying method, respectively. Especially, the difference depending on drying method was remarkable; the sun dried sample showed higher value than that of the oven dried sample, about maximum 80% for capsaicin and 60% for dihydrocapsaicin.
A Review Study of Food Poisoning in Korea
Journal of Food Hygiene and Safety, volume 4, issue 3, 1989, Pages 199~255
We reviewed studies on food poisoning in Korea from 1959-1988. Three hundred fifty three papers including original articles, review articles, and special editions were selected from thirty two journals and others. In the late 196Os, sujects related with environmental pollution were found. After the middle 1980s, the number of papers abruptly increased owing mainly to publishing the Korean Journal of Food Hygiene. The most frequently studied subject matter was Salmonellosis.
Higher Alcohols composition in Korean Alcoholic Beverages
Journal of Food Hygiene and Safety, volume 4, issue 3, 1989, Pages 257~261
In order to evaluate the characteristics and quality of various Korean alcoholic beverage, the higher alcohols profiles were analyzed by gas-chromatography. Total amount of the higher alcohols depended on the type and class of the liquors. Gaschromatographic analysis showed that the type of Gin, Rum and Vodka except for SB contain n-propanol mainly. The amount of the higher alcohols determined was proportional to the content of the originally fermented liquor in the whisky. The difference in the ratio of iso-amyl alcohol content to that of iso-butanol may be useful as a parameter in evaluating the class of the whisky.
