  • This study was conducted to obtain principal data on nutrition education according to college major after analyzing the nutrition status of 302 male university subjects. The 302 male subjects consisted of male students majoring in literature and science (109), food and nutrition (94), and physical education (99). Exactly 47.9% (highest among the groups) of male students majoring in food and nutrition ate regular meals, 39.4% ate breakfast. Precisely 29.4% of subjects majoring in literature and science never ate out. Exactly 23.2% of subjects majoring in physical education over ate frequently, and 31.3% enjoyed eating out. Intakes of protein, fat, vitamin A, $B_1$, $B_2$, $B_6$, C, E, folic acid, Ca, Fe, sodium, and cholesterol among male students majoring in food and nutrition appeared to be significantly higher compared to those of other groups (p<0.05). Intakes of energy, Zn, dietary fiber, and cholesterol among male students majoring in physical education were higher, whereas intakes of all nutrients except for dietary fiber by subjects majoring in literature and science were lower than the other two groups. Exactly 20.2% of male students were interested in health. We found that 52.4% of subjects considered exercise as an important factor for maintaining health. Smoking rate was the highest (43.6%) among male students majoring in nutrition, and the drinking rate was highest (56.0%) among male students majoring in literature and science. We found that smoking was continued as a habit (61.5%) while drinking was essential for social relationships (73.9%). From this study, it was found that male students have problems associated with eating regular meals, skipping breakfast, overeating, and intake of unbalanced foods. Also, male students who majored in food and nutrition demonstrated problems in applying their knowledge to proper dietary habits. In conclusion, a systemic educational program needs to be introduced to promote healthful dietary habits in male students.

  • This study was conducted to evaluate the increase of DPPH radical scavenging activity of meat substitute by heating. The meat substitute showed higher DPPH radical scavenging activity than those of other foods rich in protein such as beef, pork, chicken, and soybean curd. The DPPH radical scavenging activity of meat substitute was dependent upon concentration, heating temperature and heating time of meat substitute. The DPPH radical scavenging activity of meat substitute was enhanced with increasing heating temperature and time. The increase of DPPH radical scavenging activity was only applied to meat substitute without showing any activation in other foods rich in protein such as beef, pork, chicken, and soybean curd.

  • Cabbage contained high peroxidase activity among tested plant sources. The cabbage peroxi-dase can replace horseradish peroxidase to assay glucose with glucose oxidase. The amount of glucose can be determined quantitatively by glucose oxidase-cabbage peroxidase. The opti-mum pH and temperature for enzymatic glucose determination by glucose oxidase-cabbage peroxidase were 6.0 and 35-45$^{\circ}C$ respectively. The glucose assay was inhibited by addition of various metal salts such as mercuric chloride lead acetate silver nitrate ammonium molyb-date sodium tunstate and cupric sulfate. The relationship between absorbance and amount of glucose was linear up to 8.33 mM glucose in the assay mixture under the assay conditions.
