Improvement in the Quality of Takju by the Combined Use of Aspergillus kawachii and Aspergillus oryzae
The Korean Journal of Food And Nutrition, volume 4, issue 2, 1991, Pages 115~124
In order to improve the quality of Takju, the effect of combined use of Aspergillus oryzae and Aspergillus kawachii in brewing was investigated. The quality of Takju which was brewed by the combined use of Aspergillus oryzae CF7-koji and Aspergillus kawachii CF1-koji in equal amount was better as cmapared with that brewed by existing method using Aspergillus kawachii-koji only as koji. But the good result did not obtained when the koji was made by mixed culture of Aspergillus oryzae CF7 and Aspergillus kawachii CF1.
A Survey on Nutritional Contents of Lunchbox of Elementary School Student in Sokcho City
The Korean Journal of Food And Nutrition, volume 4, issue 2, 1991, Pages 125~132
To investigate the nutritional contents of lunchbox of students of elementary school located in Sokcho city Kangwon province, the survey was conducted from April 23 to April 26, 1991. Main dishes and side dishes in lunchbox were weighed and nutrients were analyzed from food composition table. Total daily energy and nutrients intake were reach to RDA's, except for intake of calcium, iron, vitamin A, vitamin Be and vitamin C. Children's height was positively correlated with energy and protein Intake. Fat intake was positively correlated with monthly income and intake of vitamin A was positively correlated, with number of family, This survey suggests that it need nutritional education program and school feeding to improvement of nutritional status for children.
Age-Related Changes in Body Growth, Muscle Protein Content and Cellular-Mediated Immunity and Rats Fed Stock Diets
The Korean Journal of Food And Nutrition, volume 4, issue 2, 1991, Pages 133~140
This study was designed to investigate age-related changes in body composition and cell mediated immunity. Male Sprague-Dawley rats were fed stock diet ad libitum and 12 rats were sacrified at 1, 4, 6, 12 months of age. Body weight Increased sharply from 1 to 4 months. and Increased steadily thereafter. The weights of liver, epididymal fat pads, and kidney increased in similar pattern as body weight, but their relative ratio to body weight decreased with age. The ratio of epididymal fat pads to body weight increased with age. The weight of extensor digitorium longus, coleus and plantaris increased from 1 to 4 months, but it decreased at 6, 12 months. The protein content of muscles decreased or increased through- out 12 months. The T cell proliferation response to Con A stimulation was significantly lower at 6 months than 1 month and lower at 12 months than 6 months.
Extraction Conditions of Barley Tea in Cylindrical Packed Column
The Korean Journal of Food And Nutrition, volume 4, issue 2, 1991, Pages 141~148
In order to Investigate the extraction mechanism of barley tea in cylindrical packed column, pilot plant scale packed column was designed and constructed. And extraction conditions for steady flow in the packed column were searched. The main results of this study are as follows ; 1. Circulation of the stock barley tea before the extraction running was indispensable In consideration of inequality, gas, particles existed in packed bed. Solid-liquid equilibrium was initially maintained after the circulation. 2. Flow direction of solvent must be up-flow for maintaining the constant bed height and flow rate during the extraction. Paessure drop in pucked bed was similar to decrease ratio of extract concentration. 3. The porosity of packed bed was in the range of 0.24∼0.36 according to the particle sloe. And it was decreased as the particle size became smaller.
Effect of Acidic Polysaccharides of Korean White Ginseng on Lipolytic Action of Toxohormone-L from Cancerous Ascites Fluid
The Korean Journal of Food And Nutrition, volume 4, issue 2, 1991, Pages 149~154
This study was devised to observe the inhibitory effect of 7 kinds of the acidic polysaccharide fraction(PGI, PGa, PG3, PGa, PGs, PG6 and PG7) from Korean white ginseng on a lipolytic action of Toxohormone-L. Toxohormone-L is a lipolytic factor, found in ascites fluid of .sarcoma -180 bearing mice and of patients with hepatoma. A substace that inhibited the lipolytic action of Toxohormone-L was isolated from white ginseng powder. This substance was an acidic polysaccharides. In vitro test showed that the inhibitory effect of PGs fraction of the lipolysis by Toxohormone-L was highest percent among other treatments at concentration of 50, 10, 200, 500 and 1,000 Ug/ml of reaction mixture. And total inhibitory activity(units) of PGI and PG4 was highest among other treatments at the same concentration and that of 10 Ug/ml.

The blocked N-terminus and N-terminal sequence of soybean B-amylase were aetermined by analyzing the acidic peptides derived on peptic digestion of the enzyme. The acidic peptides were separated from the digest on a Dowex 50
2 column(1X5cm) and purified by reversed phase-high performance liquid chromatography(RP-HPLC). The major acidic peptide, PEP-1, was a heptapeptlde. The N-terminal 7 amino acid sequence of soybean B-amylase was deduced to be acetyl-Ala-Thf-Ser-Asp-Ser-Asn-Met- from the results of sequence analysis of PEP-1 and amino acid analysis of other acidic peptides.
Effects of Stearic Acid on the Autoxidation of Rice Bran Oil
The Korean Journal of Food And Nutrition, volume 4, issue 2, 1991, Pages 167~174
In the present study, an attempt was made to Investigate the effect of stearic acid on the autoxidation of the commercial rice bran oil, Rice bran oil samples with stearic acid at 0.1, 0.3 and 0.5oh level were kept at 45
for 40 days. The rate of autoxidation of each samples was estimated regularly on the basis of the changes of peroxide value, acid value, anisidine value and the fatty acid composition. The results were as follows : The peroxide, acid and anisidine values of the rice bran oil with the stearic acid at 0.1, 0.3 and 0.591 levels during the autoxidation Increased as compared with that of the rice bran oil without the stearic acid. The induction period of the rice bran oil without the stearic acid, control was 19.0days, while those of the bran oil with stearic acid at 0.1, 0.3 and 0.5% levels varied 19.0 days, 17.7days and 14.2 days, respectively. In conclusion, it seemed that stearic acid acted as weak prooxidant when added at 0.1, 0.3 and 0.5% levels to the commercial rice bran oil. The prooxidant activity of the stearic acid appeared to depend on the oxidative mechanism and their concentration.
A Survey of Protein Nutrition of Rural Adults in Korea and A Correlation between Their Protein Nutrition and Their Food Habits
The Korean Journal of Food And Nutrition, volume 4, issue 2, 1991, Pages 175~186
The purpose of this study is to provide useful information which will aid in the promotion of nutritional policy in the Korean rural area which are derived from a survey of intake and source of protein in some Korean rural adults and the correlations between their protein nutrition and various nutrients, the uses of tobacco, alcohol, coffee, etc. The survey was conducted from July, 24 through July, 18, 1989. The healthy subjects were 45 males(average age 42.3, average BMI 22.1kg/m2) and 55 females (44 years, 21.2 kg/m2) residing in Sungjoo Kyun, Chulanam-Do, Korea. The subjects were examined for the anthropometric, food Intake and food habits. Their daily diets were measured by 24-hr recall method. The results can be summarized as follows : The daily mean protein intakes of male and female subjects were 9595 of RDA(66, 5g) (16. 7% of total food intake per day) and 102.3Bh of RDA(61g) (14.8% of total intake per day) respectively. The order of sources of animal protein in all subjects was fish(47.9%), meat(29.8%), milk (12%), and egg(10.3%). Among protein sources the intake frequencies of fork and chicken were higher than those of others. The protein nutrition of the subjects showed positive correlations with energy and fat, carbohydrate, fiber at the level of significance of 1%. The protein nutrition of the male subjects showed no correlation with age, BMI, uses of alcohol, coffee, medicine, but the plant protein nutrition showed a positive correlation with smoking and exercise(at 5%). And the protein nutrition of the male subjects showed no correlations with uses of tobacco, alcohol, coffee, medicine and their opinion of their present state of their health, but the age of the male subjects showed negative correlations with milk(at 1%) and egg(at 5%). In conclusion, the daily protein Intake was good and the main sources of animal protein were fishes in rural adults. The protein nutrition of the subjects showed a correlation with energy, fat, carbohydrate and in the case of female, milk and egg intakes showed the negative correlation with age.
A Survey on the Dining out of Western Food in Seoul Area
The Korean Journal of Food And Nutrition, volume 4, issue 2, 1991, Pages 187~198
This study was surveyed by 192 male and 238 female eating-out behaviors about western food in Seoul. The results were summarized as follows : The recognition degree about the western food was 14.2% In
, 54.891 in
, 25.3% in
and was observed significance by sex, food expenses and dine-out expenses. The recognition degree about western food was observed more highly than expected and would be further more highly with westernized dietary culture. The information of concern and knowledge about western food was taken by mass-communication, book, school education, etc. and the answer marked significance by sex. age, school career. The majority of subjects had chosen Korean restaurants in dining-out and the western restaurants were favorable to twenties(20~29) and thirties(30~39). The frequency of western restaurants visits was 46% in
, 39% In
and the answer of frequency had significance by age, food expenses, and dine-out expenses. The choice of western A la carte menu restaurants was chicken restaurant(28%), cutlet restaurant(24%), hamburger R. (13%), pizza R. (19%), Spaghetti R. (9%). hamburger restaurants were favorable to twenties and the majority of pizza restaurant chosen were high level by monthly income. Content to be improved in western food was 68% in
proper taste in Korean
. Western cook should be improved properly in Korean tasting.
