Ginseng-vinegars were produced by the fermentation of 5% ethanol solution contained ginseng, red ginseng, ginseng marc and red ginseng marc using Acetobacter aceti 3281 for 26 days at 35
. The ginseng and red ginseng vinegar contained 0.236mg/ml of total sugar 0.236mg/ml of reducing sugar and 0.05% of ethanol and 1.005 of specific gravity 8,58CFU of viable cell count 3,24 of pH and 5.11% of acidity. Whereas the vinegars produced using the water-extracted red ginseng marc and the ethanol-extracted red ginseng marc were consisted of total sugar was 1.27mg/ml and 1.60mg/ml reducing sugar was 0.077mg/ml and 0.725mg/ml specific gravity was 1.001 and 1.004 the number of viable cells was 8.51CFU/ml and 8.1CFU/ml pH was 2.81 and 2.89 acidity was 5.18% and 5.32% respectvely ethanol concentration was 0.05% in both cases. In five-grade scoring test of sensory evaluation, it was estimated favorable that each vinegar made by were-extracted red ginseng marc, ethanol-extracted red ginseng marc ginseng and red ginseng ginseng from 0.5 to 32% of water-and ethanol-extract red ginseng was extracted with 10% white vinegar for 30 days. The best sensory vinegars were obtained that ginseng of 0.4~1.6% above red glnsend of 0.8% water-extracted red ginseng marc of 0.8~1.6% and ethanol-extracted red ginseng marc of 0.4~1.6% added in 10% white vinegar respectively.
Studies on Persimmon Wine
The Korean Journal of Food And Nutrition, volume 12, issue 5, 1999, Pages 455~461
The possibility of wine making from soft and dried persimmon and the effects of treatment for persimmon on the quality of wine have been investigated. Soft persimmon was pretreated by two method of heat and hydrochloric acid treatment. Fermentation mash was composed of 12% persimmon and 15% of sucrose and was fermented at 17
for 36 days. The fermentation using persimmons which were untreated and treated by acid was not successful because of contamination caused by lactic acid and acetic acid bacteria. Acidity of the fermented broth produced from boiled dried acid treated and untreated persimmon was 4,4, 5.0, 5,8 and 13.5ml(0.1N NaOH/10ml broth) respectively. Ethanol concentration of the fermented broth produced from boiled dried acid treated and untreated persimmon was 11.2, 10.0, 9.4 and 6.1% v/v respectively. The wine fermented for 28day's fermentation using boiled persimmon as substate had the best quality and stability. After 36day's fermentation using boild persimon following composition was obtained: 4.65% of total sugar 3.65% of reducing sugar 0.03mg/ml of protin 0.17
/ml of amino acid and 13.02
g/ml of pectin. The pH and yeast cell of the boiled persimmon broth were 3.4 and 5.75 logCFU/ml. Fermented wine using dried persimmon had aslo good quality but the fermentation rate was slow.
A Study on Dietary Attitude of Male Employees of Higher Education according to Obesity
The Korean Journal of Food And Nutrition, volume 12, issue 5, 1999, Pages 462~469
The study purpose was to investigate pattern of dining-out and effects of obesity on the dietary attitude of the 213 male employees with high educational background. The results are as follows : Subjects were 20's bachelor and unmarried mostly. Mean height weight BMI and fat(%) were 172.1cm 70.5kg 23.8 and 21.3% respectively. The most frequency for dining-out was 3∼4 times/week Younger unmarried subjects had more dining-out. The most common meal for dining-out was dinner there being no connection with age, education level marrige and income. The most favorite food style among the subjects was Korean-style. Obese subjects answered that the took more consideration into nutritional balance regularity and proper amount of diet. Also they showed more food-intake especially animal protein and fats. all subjects had scores in dietary attitude there being no connection with obesity. Despite of high education they showed poor dietary attitude. Thus it is necessary to develop the nutritional education program for proper nutritional status of employees.
Studies on Food Components and Food Additives Affecting the Growth Patterns of Helicobacter pylori
The Korean Journal of Food And Nutrition, volume 12, issue 5, 1999, Pages 470~477
The purpose of this study was to choose prinicipal food components contained in diet foods and food additives used for manufacturing processed foods and elucidate their in vivo effects on the growth pattern of Helicobacter pylori. To do this the antibacterial effects of various sources of carbon nitrogen and mineral as an effect agent on Helicobacter pylori were first assessed based upon bacterial growth degree. results show that the source of carbon tested had different effects on bacterial growth of Helicobacter pylori. It was revealed that a promotional effect of monosaccharides resulted in enhanced growth of Helicobacter pylori compared with disaccharides and polysacchrides, in particular glucose was observed to be most effective in growth of Helicobacter pylori among monosaccharides teste whereas mannose to hinder the growth of Helicobacter pylori. Polyols such as sorbitol mannitol maltitol and xylitol was however observed to show no promotion or suppression effect on growth of Helicobacter pylori. Apart from these the sources of amino acid and inorganic nitrogen were chosen and tested to assess the promotion or suppression effect of nitrogen sources on growth of helicobacter pylori. It was found that amino acid such as lysine showed its promotion effect on the growth of Helicobacter pylori while arginine (NH4)2SO4 and NH4Cl showed no effect on its growth. Ammoia and urea were however observed to have a positive effect on the growth of Helicobacter pylori. Among these effect agents lysine and methionine were revealed to show the most positive effect on growth of Helicobacter pylori. Minerals such as MgSO4 KH2PO4 and MgCl2 appered to exert their positive growth effects whereas CaCl2 and CaSo4 had a little effect. In addition FeSO4 FeCl2 and FeCl3 brought suppression on the growth of helicobacter pylori. In studies of the growth of Helicobacter pylori by food additives ascorbic acid showed extreme suppression on its growth,. Sodium nitrate and sodium chloride were also found to be of negative effect on the growth of Helicobacter pylori in rder of degree whereas tocopherol had nothing to do with microbial growth.
The Nirite Scabenging and Electron Donating Ability of Potato Extracts
The Korean Journal of Food And Nutrition, volume 12, issue 5, 1999, Pages 478~483
This study was conducted to investigate functional properties of 70% acetone extract in different parts of two potato varieties. 'Superior' and 'Atlantic' potato were processed by following method. Potatoes are washed, peeled, sliced and steamed before hot air drying for flesh and peel powder. Hunter's L and b values of flesh powder from blanched 'Superior' potato were higher than flesh powder from fresh 'Superior' potato. Discoloration of 'Superior' potato was inhibited by steam blanching. Contents of total polyphenol and chlorogenic acid in the 70% acetone extract of 'Superior' potato were higher than those of 'Atlantic' potato paticularly in the blanched flesh and peel. But flavonoid was not detected in flesh extract. The phenolic concentration was not decreased by the heat treatment. The nitritescavenging and electron donating ability was greatest at the tuber peel including the skin and cortex tissue 1mm beneath the skin. From the above results browning reaction and polyphenol contents in different parts of potato slices were dependent on cutivars. Peels contained more polyphenols than those from the flesh. The results indicate that potato peel extract of steam blanched plus hot air dried potato tuber showed the effectiveness as a natural nitrite scavenger and antioxidant.
Roasting Conditions for Improvement of Viscosity and Sensory Properties of Sea Tangle Extracts
The Korean Journal of Food And Nutrition, volume 12, issue 5, 1999, Pages 484~489
Rosting conditions for improvement of viscosity and sensory properties of sea tangle extracts were investigated. The supernatant % solid yield and crude protein yield were increased by increasing of roasting temperature and times. The highest contents of algin was obtained in roasting temperature of 175
ash contents were increased by roasting temperature increasing. Viscosities of sea tangle extract were significantly decreased by increasing of roasting temperature and time upto 175
and 10 mins more than further roasting conditions. The pH of sea tangle extracts slightly decreased from 5.94 to 5.83 in the roasting of 15
however at temperature more than 175
its pH was increased by increasing of temperature and time. According to increase of roasting temperature and time Lightness (L value) were significantly decreased and redness (a value) and yellowness (b value) reached the highest value in the roasting of 20
15 min. or 175
30 min and after that its value were decreased. The odor characteristics showed that sea tangle extract prepared by roasting of 175
10mins was slightly reduced in intensity of savory and seaweed taste but significantly low in intensity of nauseous taste and high in intensity of roasted taste and accetability. Overall data suggested 175
10min was the most effective roasting conditions for improvement of viscosity and sensory properties of sea tangle extract.

Comparison of Amino Acid by Appearance of Albinism in Cultured Flounder Paralichthys olivaceus
The Korean Journal of Food And Nutrition, volume 12, issue 5, 1999, Pages 496~501
Albinism is a phenomenon that color of the body surface is changed to white orfaint brown from the specific color to the species by difficiency of pigments due to mutation or disease. This study was undertaken to investigate the experimental basis on the appearance of albinism in cultured flounder Paralichthys olivaceus. The skin and muscle from the normal and albinic flounder were used by measuring contents of amino acid free amino acid. The results were summarized as follows: Contents of amino acid in theskin and muscle are different from normal and albinic flounder. Phenolic and sulfuric amino acids in the skin of normal flounder were 2 times those of albinic ones. Especially tyrosine contents of the skin in normal flounder were 24 times higher than those. Methionine was 26 times higher than those Phenylalanine was 1.6 times higher. In free amino aicd phosphoserine and phosphoethanolamine were a little higher than that ones. The melanin formation of the skin in flounder was affected by substrates such as phenolic amino acid and cofactor such as sulfuric amino acid.

Albinism is a phenomenon that color of the body surface is changed to white or faint brown from the specific color to the species by difficiency of pigments due to mutation or disease. This study was undertaken to investigate the experimental basis on the appearance of albinism in cultured flounder Paralichthys olivaceus. The skin and muscle, from the normal and albinic flounder were used by measuring contents of lipid and fatty acid, Contents of lipid and fatty acid in the skin and muscle are different from normal and albinic flounder. Contents of lipid in the skin were higher than those of muscle from flounder. The major fatty acids in both skin and muscle were palmitic acid, oleic acid docosahexaenoic acid (DHA) and eicosapentaenoic acid(EPA).
Carotenoid pigment of Pumpukin Culitivated in Korea
The Korean Journal of Food And Nutrition, volume 12, issue 5, 1999, Pages 508~512
In order to qualify and quantify carotenoid pigment of pumpukin were analyzed by HPLC column chromatography and spectrophotometry. Eightyseven percent of total carotenoids in the pumpkin was in the fiber amounting 65.33mg%. however flesh and skin contained 6.61 and 3.31mg% respectvely. A silica gel column chromatography of the carotenoids produced 2 different peaks. The components eluted in peak II showed blue color when treated with hydrochloric acid. The fact suggested it contained epoxide and the component in peak II was a monol. By the separation with HPLC.
-carotene were the major compounds in the carotenoids. In fiber the total
-carotene content was 1.6 times higher than in the flesh and skin. The fiber contained less unidentified compounds than other part which contained 27.3~32.8%
