Preventive Effect of
-Glucan on the Experimental Atherosclerosis in Rats
Journal of Food Hygiene and Safety, volume 1, issue 1, 1986, Pages 1~12
The present studies were undertaken in attempt to investigate the preventive effect of
-glucan from barley ad diltiazem on cholesterol and vitamin D2 induced-atherosclerotic rat. The results obtained were summerized as follows. 1.The group, fed only the mixture of cholesterol and vitamin D2, showed significant increase of calcium, inorganic phosphorus, total cholesterol, lipid LDL-cholesterol and phospholipid in serum, and total lipid in the liver (p<0.05) as comparing with normal group. The aorta showed severe damage of disorganization, necrosis and lipid deposition in the elastic membrane. 2. The group fed mixture of cholesterol and vitamin D2 plus diltiazem simultaneously, showed significant increase of total cholesterol, total lipid and phospholipid in serum, and total lipid and triglyceride n the liver (p<0.05) as comparing with normal group, but the significant decrease of calcium and inorganic phosphorus in serum(p<0.05) as comparing with the atherogenic control group. The aorta showed slight damage of elastic membrane and lipid deposition as comparing with the atherogenic control group. 3.The group, fed mixture of cholesterol and vitamin D2 puls
-glucan simultaneously, showed significant decrease of total cholesterol, LDL and VLDL-cholesterol, total lipid, phospholipid and triglyceride in serum, and total lipid in the liver as comparing with the atherogenic control group(p<0.05), but the significant increase of calcium in serum as comparing with the normal group(p<0.05). The aorta showed no changes in elastic fiber and no lipid deposition in comparing with the atherogenic control group.

Two short-term bioassays were employed to asses the mutagenic and clastogenic activities in browning reaction of pentose-creatine, pentose-glycine and pentose-creatine-glycine browning reaction model system. Methylene chloride extract of rhamnose-creatine-glycine browning reaction exhibited the strongest mutagenicity toward Salmonella typhimurium TA98 with S-9. Methylene chloride extract of pentose-creatine and pentose-glycine browning reaction solutions was also tested for mutagenicity, with positive responses. Methylene chloride extract of pentose-creatine-glycine browning reaction solutions induced significant increase in chromosome aberrations in the treated Chinese hamster ovary(CHO) cells. Each of pentose-creatine and pentose-glycine browning reaction solutions induced a relatively low frequency of chromosome aberrations in the treated cells.
Studies on the inhibitor of aflatoxin production by Aspergillus parasiticus R-716 - Effective extraction of vegetables and their effects -
Journal of Food Hygiene and Safety, volume 1, issue 1, 1986, Pages 23~29
In this study, th effective extraction of 5 vegetables, which have been shown to inhibit the growth of the aflatoxin production of Aspergillus parasiticus R-716, was investigated and their effects were examined. Radish, cabbage, garlic and zinger were effectively with water-chloroform, but crown daisy with n-hexane. Among them, water-chloroform extract of radish was remarkably effective, and garlic extract only inhibited the growth strongly. The growth and the aflatoxin production of the strain were showed 0.758g/25ml, 763ug/25ml with the addition of water-chloroform extract equivalent 15g of raw radish, and an increase in the level of radish extract resulted in a decrease both the growth and the aflatoxin production per mycerial weight.
A Study on the harmful trace elements in food
Journal of Food Hygiene and Safety, volume 1, issue 1, 1986, Pages 31~38
In order to investigate the harmful trace elements in Korean common vegetable, the contents of Lead, Cadmium, Copper, Zinc and Manganese are studied in this paper. As shown in the Table 1, the following vegetable samples collected from the agriculture-marine products market I Seoul were used; root vegetables-potato, sweet potato, carrot, radish, onion and garlic, fruit vegetables-cucumber, pumpkin, green pepper, egg plant, tomato and melon. The contents of the harmful trace elements were determinded by means of atomic absorption spectrophotometry. These elements were extracted from the vegetables with the DDTC-MIBK extraction method. The results were as follows; 1. The average contents of the harmful trace elements in the vegetables were as follows; Root vegetables-Lead, 0.387 ppm; Cadmium, 0.030 ppm; Copper, 1.267 ppm; Zinc, 7.395 ppm; Manganese, 5.380 ppm. Fruit vegetables-Lead, 0.259 ppm; Cadmium, 0.028 ppm; Copper, 1.155 ppm; Zinc, 3.732 ppm; Manganese, 3.532 ppm. 2. The contents of harmful trace elements in vegetables were significantly low compared with foreign standards. This means that vegetables contamination with those harmful trace elements is not significant at present.
Microbiological and Physicochemical Properties of Dried Fishery Treated with Ethylene Oxide(E. O) and Gamma Irradiation Products (Shucked Shellfish and Shucked Mussel Powder)
Journal of Food Hygiene and Safety, volume 1, issue 1, 1986, Pages 39~46
Comparison of ethylene oxide(E.O) fumigation and gamma irradiation on the sterilization, microbiological, physicochemcial and sensory quality of dried fishery products (shucked shellfish and mussel powder) were investigated. The viable cell count of mesophilic total bacterial was reduced by over 2 to 3 log cycles with irradiation of 3 to 5 kGy, and those samples were completely sterilized by irradiation dose of 7 to 10 kGy. In view of reduction of microorganisms, D10 value of each samples were ranged from 1. 36-1. 46 kGy. fungi, mesophilic spores, acid tolerant bacteria and coliforms were sterilized at 5 to 7 kGy irradiation but E.O. fumigation proved insulfficient to eliminate the mesophilic total bacteria and fungi. In the physicochemical and sensory quality of samples, such as the amino acid, TBA value, TMA-N, color difference and overall acceptability irradiated sample with optimum dose was similar to those of the nonirradiated sample, while E.O. fumigated sample was remarkably deteriorated in the physicochemical and sensory quality of samples.
Fundamental Studies on the Food Sanitation for Raw Milk in Korea
Journal of Food Hygiene and Safety, volume 1, issue 1, 1986, Pages 47~50
Sanitary condition for raw milk in Korea was investigated in this study. It is hoped that the information will be used for reference in future endeavors of study in the field of public health and food sanitation in Korea. The results were summerized as follows: 1) The viable cell counts of bacteria in raw milk were tend to be increased under the various atmospheric temperature, and the correlation coefficient between temperature and total viable cells was r=+0.921(p<0.01). 2) The correlation coefficient between methylene blue reduction time test and viable cell counts of bacteria in raw milk was r=-0.799(p<0.01). 3) The relationship between total solid rate(%) and milk fat rate(%) was highly significant level as r=+0.745(p<0.01). 4) Highly significant correlation coefficient was r= +0.945(p<0.01) between milk fat and protein rate in raw milk.
A Study on the heavy metal contents in the soils and vegetables
Journal of Food Hygiene and Safety, volume 1, issue 1, 1986, Pages 51~56
In the particular area the heavy metal concentrations in the soil were determined and compared to the contents in vegetables which were grown on the soil. Simultaneously the degree of contamination was examined. Samples were collected from Chinese cabbage, radish and Altari-mu, together with the soil on which the three kinds of vegetables have grown. The sites of samples collection were Jinguan-sa(non-polluted area) and Sangaedong(polluted area). The contents of cadimium, copper, lead and zinc were determined by means of atomic absorption spectro-photometer. The results obtained were as follows; 1. In soils, the average contents of heavy metal in Jinguan-sa area (Cd; 0.15ppm, Cu; 0.15ppm, Zn; 11.5ppm) were lower than those in sangye-dong(Cd; 0.26ppm, Cu; 13.0ppm, Zn; 17.1ppm). 2. In vegetables, the average have metal contents in Jinguan-sa were cadmium; 0.11ppm, copper; 5.29ppm, zinc; 18.75ppm and the average contents in Sangye-dong were cadmium; 0.16ppm, copper; 6.64ppm, lead; 0.14ppm, zinc; 15.01ppm. 3. The contents of lead showed zero ppm in Jinguan-sa area(soil and vegetables). In vegetables difference in concentration of heavy metals was not observed between reclaimed area and non reclaimed area. Statistical analysis showed that no correlation in the heavy metal concentrations between those in soils and in vegetables.
Hygienic Aspects of Campylobacter Enteritis
Journal of Food Hygiene and Safety, volume 1, issue 1, 1986, Pages 57~66
Campylobacter jejuni has been recognized as one of the causes of human gastroenteritis. The feces of a variety of reservoir animals contain c. jejuni as commensals in the intestinal tracts, and are fundamental source of contamination. The intestinal organisms contaminate carcasses, equipment tools hands of the processing line workers and air of the processing facility. Once the contamination happens in the slaughterhouses or the meat processing facilities, it is very difficult to keep the carcasses free from the infection of c. jejuni. Various disinfectants are effective in minimizing the number of Campylobacter infections in the processing facilities by washing contaminated carcasses, tools, and hands. Direct contact with infected animals has been incriminated in transmission of infection caused by C. jejuni. Freezing, cooling with dry air and gamma irradiation are an effective way for preserving the meat and eliminating the transmission, but broad and enforced studies are needed for the practical use.

International Tendencies for Estavlishing a Microbiogical Standard for Food
Journal of Food Hygiene and Safety, volume 1, issue 1, 1986, Pages 77~95
In 1962 the governing bodies of FAO and WHO approved the establishment of a joint FAO/WHO Food Standards Programme, the creation of a jointly sponsored body to be known as the Codex Alimentarius commission to implement the Programme. It can reasonably be claimed that the Commission has assumad the leading role in establishing internation food standards throughout the world. The Codex Committee of Food Hygiene has received much advice and assistance from other international organization which have been working in this field for a number of years. In particular, it has received valuable background documentation from the International Commission on Microbiological Specifications for Foods(ICMSF) which was set up by the International Association of Microbiological Societies(IAMS), and also from the International Organization for Standardization (ISO). Nevertheless, in spite of the information supplied by governments and research bodies in this field, microbiological standards have proved to be a highly controversial subject from the point of view of Codex standards. When it is decided to establish a microbiological standard for a food or class of foods, the following technical and administrative aspects must be considered: 1) The standard should be based on factual studies and serve one or more of the following objectives: (1) to determine the conditions of hygiene under which the food should be manufactured; (2) to minimize the hazards to public health; (3) to measure the keeping quality and storage potential of the food 2) The standard should be attainable under practicable operating and commercial conditions and should not entail the use of excessive heat treatment or the additions of extra preservatives. 3) The standard should be determined after investigation of the processing operation. 4) The standard should be as simple and inexpensive to administer as possible, the number of tests being kept to a minimum. 5) Details of methods to be used for sampling, examining and reporting should accompany all published microbiological standards. 6) In establishing tolerance levels for the permissible number of defective samples, allowance should be made for sampling and other variations due to differences in the laboratory methods. The following additional points should be kept in mind: 1) It is not satisfactory to establish one set of microbiological standards for a miscellaneous group of foods, such as“frozen foods”or“precooked foods”. 2) Microbiological standards should be applied first to the more hazardous types of food on the basis of experience of expected microbiological levels, taking into account variations in composition, processing procedures, and storage. 3) When a standard is established, there should be a definite relationship between the standard and the hazard against which it is meant to protect the public. 4) The sensitivity, reliability, and reproducibility of the sampling and analytical methods should be compared in different laboratories and the methods to be used should be specified in detail as part of the standard. 5) Tolerances should be included in the standard to account for inaccuracies of sampling and analysis. 6) Standards should be applied on a voluntary basis before compliance is made mandatory.
Immunotoxicological Aspects of Pesticides
Journal of Food Hygiene and Safety, volume 1, issue 1, 1986, Pages 97~106
Pesticides constitute a unique group of biologically active chemicals in that they are produced for deliberate release into the environment, usually to produce some specific biocidal effect. Workers at all stages of pesticide production and application become exposed, at least on an occasional basis, while some experience routine exposure. The general population is, in turn, exposed to the residues, in air, water and food. This review is intended to survey the present knowledge of the immunotoxicity of 20 pesticides. As will be readily seen, knowledge of pesticide immunotoxicology to date is largely descriptive with only modest beginnings toward understanding mechanisms underlying the effects. In most cases the effects have not yet to be defined in immunological state, and just as little is presently known about how these chemicals exert their effects. There is an equally great gap in perceiving any relationship between the structure of a chemical and immunotoxicological potential.
Commercial Utilization of Irradiation for the preservation of Foods and its Hygienic Effects
Journal of Food Hygiene and Safety, volume 1, issue 1, 1986, Pages 107~113
It is estimated that the loss of Korean agricultural and fishery products during the storage period is usually more than 20%, and it is difficult to increase agricultural products by a 10% annual rate directly. Therefore, development of food preservation techniques has now become a most important atternative for the indirect increase of such products and for its senitary distribution. Changes eating habits and improved living conditions have accelerated the demand for convenience food production and for this reason it is essential that raw materials at stable, resonable prices and hygienic quality be available the year round. At the end of 1980, the Korean government conceded th economical feasibility of the storage of foods by irradiation and a procedure for preserving food by irradiation on a batch scale was successfully developed by KAERI in 1982. Based on the research results accomplished by the KAERI and on the recommendation on wholesomeness of irradiated food by Joint Committee of FAO/IAEA/WHO in 1980, the approval of wholesomeness of irradiated food was declared by presidential decree in June 1985 and the procedure of permission for individual items is in progress. Korean private firms (Ryung Young Co.) which was technically assisted by KAERI for five years have taken mush interest in the establishment of such facilities in Korea, therefore Ryung Young Co. had proposed for the construction of 500 Kci Co-60 irradiator to the Ministry of Science and Technology in July 1984. The permission of construction has approved by government in May 1985. The commercial irradiator will be constructed as one of the most modernized facilities until May 1987 and that facilities will contribute the propagation of commercial storage of foods and its hygienic quality.
