A Study on Nutritional Management for Improvement of Exercise Capacity and Physical Fitness -For Dietary Feeding Condition-
Journal of the Korean Society of Food Science and Nutrition, volume 20, issue 2, 1991, Pages 94~102
This study was directed to further clarify the effect of resting time or dietary condition for the improvement of exercise capacity and physical fitness, and the changes of some body consitiuents and physiological functions which are related to the exercise metabolism. Sixteen male students(8 athletes and 8 nonathletes)were participated during 3 weeks(Aug. 20-Sep.9, 1989). Each subject performed two treadmill running trials at an absolute intensity (1 mintute in 3.4mph/15% slope and 2 minutes in 5.5mph/20% slope). In the resting time trials, general diet was fed before 1, 2, 4 and 12 hours of the treadmill exercise loaded. in the dietary condition trials, high carbohydrate(HC), high fat(HF) and high protein(HP) diet were fed before 2 hours of the treadmill exercise loaded. Control trial was that of resting time before treadmill exercise loaded after 12 hours of general diet feeding. Measurement were made to study the change of blood glucose, palmitate, lactate, blood pressure and heart rate. The results obtained are summarized as follows: Mean daily metabolizable period. In resting time trial, the blood glucose concentration of athlete and nonathlete from 2 hours group was similar to control group. The blood palmitate concentration of athlete was increased in 1 and 2 hours group but those of nonathlete was not only increased in 1 and2 hours group but was more increased in 12 hours group, compared with both control group. The blood lactate concentration was increased in all experimental group, compared with both control group and those of nonathlete was much higher than athlets. The elevation rate of blood pressure in pre-and after-exercise of athlete was lower than those of nonathlete. In dietary composition trial, the blood glucose concentration of athlete and nonathlete in HC group was higher than other diet groups. The blood lactate concentration of athlete and nonathlete in HC group was lower than other diet groups. There was no remarkable change of the blood palmitate concentration and heart rate in each dietary composition trial, but those of nonathlete was low in HC and high in HP group. In above results, it was suggested that the effective condition of resting time and dietary composition for the improvement of exercise capacity of nonathlete may be 2 hours and HC diet, respectively. But it was showed that the exercise capacity of athlete may not be affected by experimental condition of resting time, except 1 hour after feeding or of dietary composition because of well adaptation in new exercise condition.
A Study on the Riboflavin Intake and EGRAC of Young Healthy Korean Women
Journal of the Korean Society of Food Science and Nutrition, volume 20, issue 2, 1991, Pages 103~110
This study was conducted to determine riboflavin status of young healthy Korean women. Eight subjects consumed general Korean diet for 3 weeks. Riboflavin intake was measured during the period and Erythrocyte Glutathione Reductase Activity coefficient (EGRAC) was analyzed at the end of experimental period. The subjects who showed EGRAC value above 1.20 were supplemented 6 mg riboflavin per day for 1 week. The average age of subjects was 22.1 years old, height was 154.4cm, weight was 49.2kg, chest circumference was 81.2cm, the sum of skinfold thickness of 3 parts was 79.5mm and Body Mass Index(BMI) was 20.6. Hemoglobin concentration was 13.0g/100ml, hematocrit value was 44.0% A/G ratio was 1.4, and the activity of sGOT, sGPT, alkaline phosphatase was 14.3, 11.0 and 6.5, respectively. The average daily intake of energy, protein and riboflavin was 1745kcal, 56.1g and 1.14mg, respectively. The mjor source of riboflavin were milk, egg, Korean cabbage, rice, beef and so on. The average EGRAC value was 1.2748. percentages of subjects who showed EGRAC value above 1.20 was 65.2%. After oral administration of 6mg riboflavin, the EGRAC value of all these subjects was returned to normal range. Riboflavin intake was correlated positively with energy as well as protein intake, and correlated negatively with EGRAC value. However, riboflavin intake per 1,000kcal was not correlated with EGRAC value.
Effects of Heated Oil and Vitamin E on Lipid Peroxidative Liver Damage in Rat
Journal of the Korean Society of Food Science and Nutrition, volume 20, issue 2, 1991, Pages 111~120
In order to investigate the cellular peroxidative damage due to heated oil intake and the preventive effect of vitamin E on it rats were fed heated corn oil with acid value of 4.02 at the level of 10 Cal% and three different levels of vitamin E that were 0, 40 and 200 mg/kg diet. Control group was fed fresh corn oil and 40mg/kg diet of vitamin E. After ech feeding period of 0, 3 and 6 weeks, liver superoxide dismutase (SOD), glutathione peroxidase (GPX) activities and microsomal content of vitamin E and lipid peroxide (LPO) were measured as well as cellular morphology was examined. SOD activities and LPO contents were higher, while GPX activities and vitamin e contents were lower in heated oil groups than control group. Electromicroscopic observation revealed the loss of inner mitochondrial membrane and cristae and irregular arrangement of nuclear membrane and chromatin in heated oil groups. As dietary vitamin e level was increased, SOD activity and LPO content were decreased, but GPX activity and vitamin E content in the liver increased and cellular peroxidative damage reduced progressively. This phenomena was more remarkable in 6 weeks of feeding than 3 weeks.
Effects of Onion Diet on Carbon Tetrachloride Toxicity of Rats
Journal of the Korean Society of Food Science and Nutrition, volume 20, issue 2, 1991, Pages 121~125
This study designs to investigate effects of onion diet on carbon tetrachloride toxicity of rats. Experiments were performed with week's feeding, body weight, food intake, ratio of orgen weight/dody weight, serum lipid levels, superoxide dismutase and catalase activity and malondialdehyde(MDA) content in liver and kidney were determined. The content of serum total cholesterol in each group were lower than those of control group(p<0.05), especially at onion juice treated group. Serum HDL-cholesterol level of CBB and CBJ groups was significantly lower than that of control group (p<0.05). Superoxide dismutase activities of liver and kidney were significantly increased by carbon tetrachloride treatment and decreased by onion feeding. MDA contents in liver and kidney of CCl4 treated rats were significantly decreased by boiled and fresh onion fed group, compared with CCl4 treated control group. This result suggested that onion diet has a protective effect of CCl4 induced hepatotoxicity and nephrotoxicity of rat.
Estimation of the Efficiency of Dietary Protein Utilization Based on the Urinary Excretion of Acid-Soluble Peptides in Rats
Journal of the Korean Society of Food Science and Nutrition, volume 20, issue 2, 1991, Pages 126~132
Nutritional factors affecting the urinary excretion of acid-soluble peptides(ASP) in rats were studied using protein-free diet, gluten diet, casein diet, and gluten supplemented with lysine and threonine(GLT) diet. The content of urinary ASP was lowest in protein-free diet group among the four kinds of diets above. But the amino acid pattern of urinary ASP in the four dietary groups were similar each other, suggesting that urinary ASP is mainly from endogenous origin under these nutritional conditions. The efficiency of dietary protein utilization was significantly lower in gluten diet than that of casein diet or GLT diet. Those findings suggest that the rate of urinary excretion of ASP-form amino acids can be employed as an index of protein metabolism, particularly as a simple index in the assessing the status of protein nutrition.
Changes in Quality of Shiitake Mushroom (Lentinus edodes) during Modified Atmosphere(MA) Storage
Journal of the Korean Society of Food Science and Nutrition, volume 20, issue 2, 1991, Pages 133~138
Several quality indices of Shiitake mushroom (Lentinus edodes) were measured during storage at modified atmosphere (MA) conditions made by plyethylene film bag with different thicknes. IN the mushrooms kept in the thicker film bag, larger amounts of ethyl alcohol and acetaldehyde were produced during storage. The lowest weight loss was marked by the mushrooms kept in 0.06mm thick film bag. Protein content of the mushrooms was increased with the storage period without any storage period without any significant trend depended on the storage treatments and electrophoresis pattern of protein was changed little in the mushrooms kept in 0.04mm thick P.E. film bag during storage.
The Effect of Cellophane Film Packing on Quality of Semi-Salted and Dried Mackerel during Processing and Storage
Journal of the Korean Society of Food Science and Nutrition, volume 20, issue 2, 1991, Pages 139~147
The preservative effect of cellophane film packing on the quality of semi-salted and dried mackerel was studied. The product(P) of semi-salted and dried mackerel was prepared from raw mackerel by filleting, cleaning, soaking in 15%9v/w) salt solution for 30min, draining, packing with cellophane film (PT# 300, thickness:
) and drying for 4 hrs at
in hot air dryer. The product (C) was also prepared without cellophane film packing after draining. The product (C) and (P) were stored at
. After processing and during storage, moisture content of product (P) was higher than that of product (C), but contents of VBN(volatile basic nitrogen), amino nitrogen and TMA of product (P) on dry basis were lower than those of product (C). Viable cell count, TBA value, peroxide value and decreasing rate of polyenoic acid of product (P) were also lower than those of product (C). In sensory evaluation, the shelf life of product (C) was about 9 days and that of product (P) was about 14 days. From the results of chemical and sensory evaluation, it was concluded that cellophane film packing was a good condition for preserving the quality of semi-salted and dried mackerel.
Antioxidative Materials in Domestic Meju and Doenjang 1.Lipid Oxidation and Browning during Fermentation of Meju and Doenjang
Journal of the Korean Society of Food Science and Nutrition, volume 20, issue 2, 1991, Pages 148~155
Lipid oxidation and browning during fermentation of domestic Meju and Doenjang were examined in order to elucidate the antioxidative effects of browning products and phenol compounds from Meju and Doenjang. Peroxide values of lipids from Meju were detectable and slightly increased until 3 weeks of fermentation, but started to be decreased after 3 weeks of fermentation and notdetectable after 6 weeks. Peroxides were not detected in Doenjang during the whole fermentation, but started to be decreased after 3 weeks of period of 22 weeks fermentation. Carbonyl value were increased during the whole period of Meju fermentation, but started to be decreased at the early stage of Doenjang fermentation. Hydrophilic fraction of browning products from Meju was much higher than lipophilic fraction and the former fraction was dramatically increased at the early stage of the fermentation. But the both fractions maintained high values during Doenjang fermentation. Hydrophilic browning products and phenol and phenol compound in Meju showed strong antioxidative against linoleic acid.

Journal of the Korean Society of Food Science and Nutrition, volume 20, issue 2, 1991, Pages 162~166
Twenty brands of five different types of deep-fat fried foods including doughnuts, vegetables, fried chicken and french fries were purchased from food stores and fast food restaurants in Daegu city. These sample were analyzed for their total lipid content and fatty acid composition. The total lipid contents of each type of foods were over 20% by weight on an average. One brand of the doughnuts had the highest lipid content of 55.2%. The average polar lipid content of the five different types of samples was approximately 40% of the total lipid content. The fatty acid compositions of the total lipid in the deep-fat fried foods were similar to one another. HTe major fattyacids were oleic acid, stearic acid, linoleic acid in order of content. Minor fatty caids ere myristic acid, palmitic acid, palmitoleic acid, linolenic acid, behenic acid and erucic acid.

Journal of the Korean Society of Food Science and Nutrition, volume 20, issue 2, 1991, Pages 179~186
The nutritional requirement and cultural condition such as carbon and nitrogen sources, cultural temperature, initial pH, cultural time and aeration for the production of endocellular cytosine deaminase from Aspergillus fumigatus IFO 5840 were investigated. The cultural broth giving maximum cytosine deaminase yield was found to consist of 2% glucose as a carbon source and 1% yeast extract and 0.1% peptone as a nitrogen source. Optimal initial pH of the culture broth was pH 8.5 and the enzyme production in the cell usually reached a maximum after 28 hours of cultivation in the 500ml shaking flask containing 100ml broth at
. The endoenzyme production of the used strain was inhibited by inorganic nitrogen, but activated by orgainc nitrogen, yeast extract.
Modulation of the Aging Process by Food Restriction
Journal of the Korean Society of Food Science and Nutrition, volume 20, issue 2, 1991, Pages 187~196
Aging is the progressive accumulation of changes with time associated with responsible for the ever-increasing susceptibility to disease and death which accompanies advancing age. Lipid peroxides easily produced in the membrane system by the chain reaction of free radicals which occurred from various environmental factors. The amount of lipid peroxides produced in biological system increased with aging process, and lipid peroxidation damages involved in aging process and pathological disorders. Although lipid peroxides have such deleterious effects on the organisms, there are numerous substances and mechanisms which prevent the reaction of peroxide formation and protect the subject from its toxicity. This review provides an overview of how does lipid peroxidation of unsaturated lipids take place by free radical, and what is the intervention of lipid peroxides in pathogenesis of some human diseases, and also how does food restriction influences the aging process and various pathological disorders. The major focus of this paper is to review the evidence indicating that food restriction retards the aging process, and possible mechanisms of its actions. Therefore, it discussed the effects of age and food restriction on life-span, membrane yield, lipid peroxidation, fatty acid composition and peroxidizability, cholesterol and triglyceride levels, prostaglasndin and thromboxane synthesis, which may be concerned with blood flow, membrane fluidity, homeostasis and glomerular filtration rate in living body.
