Worsens Actual Condition and Formative Factors of Dietary Habits
Han, Yang-Il ; Nam, Gung-Seok ; Seol, Min-Yeong ;
The Korean Journal of Food And Nutrition, volume 2, issue 2, 1989, Pages 1~7
This investigation revealed not only the women's actual condition of dietary habits, but also the factors related to the formation of them. The subjects were 400 women at Seoul area. The results were as follows. 1. It was observed that their home descipline, the school education and consciousness were all related to the formation and their dietary habits, And that the practice and experience of preparing mea Is were most important in order to cultivate their good dietary habits 2. Actual condition of dietary habits were generally not satisfactory.

The Korean Journal of Food And Nutrition, volume 2, issue 2, 1989, Pages 8~13
A strain of Saccharomyces cerevisiae BY-366 was found to produce a strong sucrose-hydrolyzing enzyme Using this strain, the optimal culture conditions for the production of invertase were investigated. The results are as follows : 1. For enzyme production, optimal temperature, initial pH and critical concentrations of sucrose and raffinose were 3
, 5.0 and 3.0%, respectively. 2. Enzyme production was reached maximum by organic nitrogen source, 0.3% yeast extract plus 0.5% bactopeptone. 3. It was appeared the presence of 0.1 M Mn2+ and Fe2+ ion was essential factors, on the other hand, 0.1 M Ag+ and Hg2+ ion almost block in yeast growth and enzyme production. 4. Invertase productivity was reached maximum within 3 days on stationary culture with medium-composed of sucrose 3%, bactopeptone 0.5%, yeast extract 0.3%, KEHPO. 0,1%, MgSO4.7H2O 0.05%.

A strain of Saccharomyces cerevisiae BY-366 was isolated to produce a strong sucrose-hydrolyzing enzyme. After entrapment of yeast cell invertase with alginate, enzymatic properties of immobilized cells were investigated. The results are as follows. 1. The optimum pH of invertase in immobilized cells and non- immobilized cells was 6.0 and 5.0, and pH stability of invertase in immobilized cells and non- immobilized cells was 6.0 and 5.0, respectively. 2 Activation energy of immobilized cells was 4.7 kcal/mol. 3 The immobilized preparation exhibited high resistance to heat and urea Induced denaturation. 4, The bead size less than 2 mm in diameter was desirable. 5. In spite of repeated use, the enzyme activity of immobilized cells was inhibited slightly in batch reaction, and a small column of the immobilized preparation could hydrolyze relatively high concentration of sucrose almost quantitatively to more than 6 days.
Studies on the Digestion of Beef by Ficin Treatment V. A Transmission Electron Microscopic Observation
The Korean Journal of Food And Nutrition, volume 2, issue 2, 1989, Pages 21~26
The morphological changes of fresh beef treated with ficin(0.1% : 2 hrs, 6 hrs)were examined with transmission electron microscope(TEM), the results obtained were as follows ; Connective tissue protein in fresh beef treated with ficin became gradually fragmentation and was occurred solubilization with time The length of sarcomere in myofibrillar protein was elongated, M-line became dim, and the 1-band of Z-line was broken and beck me fragmentation with time.
Effect of KEUMSUNYEON on Lipolytic Action of Toxohormone-L from Cancerous Ascites Fluid
The Korean Journal of Food And Nutrition, volume 2, issue 2, 1989, Pages 27~30
This study was devised to observe an inhibitory reaction toward an lipolytic action of toxohormone-L from KEUMSUNYEON powder. Toxohormone-L is known to be a lipolytic factor that was purified from the ascites fluid of sarcoma 180-bearing mice and of patients with hepatoma. KEUMSUNYEON powder was found to inhibit toxohormone-L induced lipolysis at its concentration of 0.5 mg/ml.
A Study on the Sex Bias in Intrahousehold Food Distribution
The Korean Journal of Food And Nutrition, volume 2, issue 2, 1989, Pages 31~39
The objective of this study is to collect basic data about sex bias in intrahousehold food distribution, by investigating 124 housekeepers living in Seoul . This Survey was performed using questionnaire about the experience of male-female dietary disparity and the attitudes about sex-differential nutrition Results were summarized as follows ; 1. 38% of housekeepers had been experienced in male-female disparity of food distribution at meal time in her childhood. Protein foods(meats & fishes) and special foods were not distributed evenly to both sexes. 2. The major causes of these unbalanced, sex-differential food distribution was rather masculine priority than food shortage. 3. Compared with the past, male-female dietary disparity was disappeared. However, 47.7% of housekeepers took more care for son's meals than daughter's, consciously or unconsciously.

For the study of the effect of dietary phospholipid (PL) on the lipid components of serum and organ tissues in Sprague-Dawley rats, 56 Male-rats were divided into 8 groups, which was composed of 7. One group was fed with basal diet (normal group). And other experimental groups were fed ad libitum with the mixture of carbohydrate. casein salt mixture : vitamin mixture(60:18:4:1) and at the same time fed administratively with 1 gram of phospholipid-free soybean oil, corn oil and sesame oil, and phospholipid-containing soybean oil, corn oil and sesame oil respectively After 60 days the rats were fasted for 12 hours and then decapitated to collect blood and separate organ tissues . The lipid and protein components of serum and organ tissues were analyzed. The results of this study are summarized as follows The supplementation of dietary phospholipid decreases the food efficiency ratio and the growth rate of experimental rats, it increases the level of serum phospholipid and cholesterol ester, but decreases the value of total-cholesterol (T-chol.)/PL ; it decreases the value of albumin/globulin (hyG ratio) of serum protein and it increases the level of phosphatidyl ethanolamine(PE) in serum and organ tissues. And the correlation coefficients among the contents of T-chol., of HDL-chol. and of phospholipid in serum and liver are negative in general. Therefore 1 think that we must eat dietary phospholipid unpurified from vegetable oil to prevent development of atherosclerosis and fat liver.
A Study on the Biochemical and Nutritional Inquiry of Antler
The Korean Journal of Food And Nutrition, volume 2, issue 2, 1989, Pages 65~71
Deer horn has been used in oriental medicine and folk remedy. It has had much effects on 'health and tonic efficacy' But this word, 'health and tonic efficacy', is very obscure in modern sense This report attempts to investigate their scientific and objective effects among many papers. The biochemical components of antler are composed of pentoses, hexoses, acid mucopolysaccharides, free and ester fatty acids, glycolipids, phospholipids, prostaglandins, sterols, protein and peptides, free amino acids, minerals, hormones etc. Deer horn extract especially increases body weight gain and feed efficiency, and it stimulates the ability of spermatogenesis of animal. However, a few papers have reported concerning the toxicity and side effects of antler.
