Microbial Growth in Dried Fishes During Preservation
Journal of Food Hygiene and Safety, volume 8, issue 3, 1993, Pages 135~140
Dried fishes such as dried pollack, dried sliced squid, dried white bait, dried anchoy) and dried cod used to cook Korean traditional foods were airpacked in polyethylene tube and irradiated with 7 kGy of gamma-ray source. The effect of gamma irradiation on microbial growth in dried fishes was investigated during storage at ambient temperature for 12 months. The total aerobic bacteria in the control group were contaminated by
in dried pollack,
in dried sliced squid,
in dried white bait,
in dried anchovy and
in dried cod and 7 kGy irradiation could eliminate the bacteria and also reduce aerobic bacterial load to 1~3 log cycle and no apparent growth of microorganisms occurred during storage. Molds in the control group were contaminated by
in dried pollack,
in dried sliced squid,
in dried white bait, 90 cells/g in dried anchovy and
in dried cod, respectively. 7 kGy irradiation could sterilize the molds and the growth of molds of nonirradiated samples were slightly decreased during storage. Yeasts in the control group were contaminated by
in dried poUack, 75 cells/g in dried sliced squid,
in dried white bait, 50 cells/g in dried anchovy,
in dried cod, respectively and irradiation could sterilize the yeasts and growth of yeasts was slightly decreased in dried pollack and dried white bait but increased in order of dried anchovy, dried cod and dried sliced squid. Coliforms in all sample were sterilized by irradiation and its growth was decreased during storage except dried anchovy.
Screening of Herb Drugs Showing Antimicrobial Activity Against Some Pathogenic Microorganisms
Journal of Food Hygiene and Safety, volume 8, issue 3, 1993, Pages 141~145
Thirty nine kinds of Korean herb drugs have screened for antimicrobial activity of some pathogenic microorganisms. It was revealed that some of hot water extracts from herb drugs showed antimicrobial activity in one or more strain of pathogenic microorganisms. Phellodendron amurense and Coptis chinensis inhibited growth of Staphylococcus aureus. Rubus coreanus showed antibacterial activity in Staphylococcus aureus and Pseudomonas aeruginosa. Citrus unshill inhibited growth of Escherichia coli and Cornus officinalis showed antibacterial activity in E. coli and Pseudomonas aeruginosa. Dioscorea battltas and Cinnamomum cassia showed antibacterial activity in Pseodomonas aeruginosa. And also, ScutelJa baicaJerrsis inhibited growth of Candida albicanus. Achyranthes japonica and Glycyrrhiza uralensis showed antifungal activity in Aspergillus niger. It was noteworthy that Glycrrhiza uranensis inhibited growth of Staphylococcus aureus, E. coli, Pseudomonas aeruginosa and Aspergillus niger.
Determination of Oxolinic Acid Residues in Acetes japonicus by HPLC
Journal of Food Hygiene and Safety, volume 8, issue 3, 1993, Pages 147~150
A novel rapid and sensitive method to detennine residual oxolinic acid in Acetes japonicus was developed. The residual oxolinic acid was extracted with ethylacetate and diluted oxalic acid, and interfering substances were removed by hexane. Fifty ppb residual concentration in the extract could be quantitated by UV-HPLC and the recovery rates were 79-91% according to the fortified amounts.
Determination of Sesame oil Adulterated with other Vegetable oils by Spectrophotometric Method
Journal of Food Hygiene and Safety, volume 8, issue 3, 1993, Pages 151~155
Since there have been no method which can applicable to the screening of commercial sesame oil adulterated with other vegetable oils, the present investigation was carried out particularily focusing on the the pattern of IN absorption of sesame oil and other vegetable oils. For this, a variety of oil samples prepared by the conventional method from sesame seeds, perilla seeds, com, soybean, and rice bran were analyzed by IN spectrophotometer. IN spectra of sesame oil and oil of unheated sesame seeds showed absorption peaks at 215, 230 and 290 nm. While UV spectra of com oil, perilla oil and soybean oil all showed absorption peaks at 215, 230 and 280 nm, that of rice bran oill showed peaks at 215, 290 320 nm. When sesame oil was mixed with com oil, perilla oil or soybean oil, respectively, from which the absorbance of peaks at 290 nm were lower than pure sesame oil. The peak at 320 nm which was typical absorption peak of rice bran oil was still observed in the spectnun of mixture of sesame oil with rice bran oil.
Effects of Antiiflammatory Agents on Acetaldehyde Induced Cytotoxicity
Journal of Food Hygiene and Safety, volume 8, issue 3, 1993, Pages 157~161
In order to get infonnations on the development of alcohol induced cardiovascular disorders, primary cultured vascular smooth muscle cells (PVSMC) were treated with acetaldehyde, one of the most reactive metabolites of ethanol. Acetaldehyde caused the striking release of lactate dehydrogenase (LDH) from PVSMC and it stimulated the prostaglandin synthesis in the same system. But it didn't induce cyclooxygenase activity. lipoxygenase inhibitors-propyl gallate and nordihydroguaiaretic acid could reverse the effect of acetaldehyde, but dexamethasone, a phospholipase
inhibitor and cyclooxygenase inhibitors except indomethacin could not protect the cells from acetaldehyde toxicity. These results indicate that enhanced prostaglandin synthesis by acetaldehyde is not a direct cause of cell death, but secondary effect due to the activation of PIAl and also, the roles of the lipoxygenase metabolites and/or
activity itself might be more important in the cytotoxicity of acetaldehyde.
Acute Toxicity of Surfactants LAS-Na and MES in Mice
Journal of Food Hygiene and Safety, volume 8, issue 3, 1993, Pages 163~169
The acute toxicity of lAS-Na(Linear Alkylbenzene Sulfonate-Na) and MES (ASME, Alpha-Sulfo fatty acid Methyl Ester), surfactans, was eyaluated in ICR mice for 14 days. Mice aging 6 weeks were administered orally with 0, 1,000, 1,320, 1,780, 2,280, 3,000 mg/kg of lASNa or 0, 1,000, 1,560, 2,450, 3,830, 6,000 mg/kg of MES in saline. The body weight of the treated animals was not significantly different from the controls. The main clinical signs of animals treated with lAS-Na or MES were diarrhea, decreased motor acthity and piloerection. The congestion in small intestine was only gross finding in dead animals treated with two sulfactants. In this study,
values of lAS-Na and MES were eyaluated 1,319 mg/kg in male and 1,402 mg/kg in female mice, 2,040 mg/kg in male and 2,548 mg in female mice, respectiyely.
Mutagenicity studies of food and cosmetic dyes (1)
Journal of Food Hygiene and Safety, volume 8, issue 3, 1993, Pages 171~179
The mutagenicity of 22 food and cosmetic dyes had been evaluated. Two different short-term mutagenicity tests were used: (1) Salmonella typhimurium preincubation assay (Ames test) (2) Chromosome aberration test with cultured Chinese hamster lung (CHL) fibroblast cells. Orange No. 203 was mutagenic in Salmonella typhimurium with and without rat liver microsomal activation, and Red No. 204 was mutagenic in Salmonelhl typhimurium with rat liver microsomal activation. Red No. 104-1 and Red No. 215 showed slight increase of chromosomal aberration in CHL cells.
