This study was to investigate regularity of breakfast and food habits of commuting local college students. The regularly breakfast eating rate was found to be 32.9% in man and 26.5% in woman. The mean score of food habits was pretty low, 36.7 out of minimum possible score 12 and maximum 60. The mean score of nutrition attitude was 58.1 out of minimum possible score 18 and maximum 90. This survey showed that skipping breakfast or irregularity of breakfast led to overeating, high fat diet, lot of alcohol and imbalanced diet. It was known that breakfast was the most important among three meals. But having balanced breakfast daily was very difficult according to loss of appetite and busy schedule early in the morning. I suggested carbohydrate food, protein food, and vitamin & mineral food items desirable for nutritionally balanced, easily digestible, tasteful, quick and easily cooking breakfast menu. It was recommended to choose on item out of each of three food categories considering calory(1/3 of daily recommended calory intake for breakfast).

In order to increase the availability of filefish scrap, the ordinary and low salt sauce were prepared, and identified their taste compounds in their products. To process the filefish scrap sauce, chopped filefish scrap was mixed with koji, 25% brine, slat and glucose (25.0 : 65.0 : 12.5 : 7.0, w/w) and fermented at $25{\pm}4^{\circ}C$ for 120 days. The same process was also carried out to process the low salt sauce adding sorbitol, lactic acid and ethyl alcohol (7.0 : 0.7 : 9.0. w/w) instead of salt. While amino nitrogen and volatile basic nitrogen(VBN) of products were decreased, pH and reducing sugar were increased all alone the fermentation period. The major free amino acids of products at final stage of fermentation were glutamic acid, alanine, leucine, lysine and aspartic acid. And the contents of total amino acid in the ordinary and low salt sauce were 4126.6(mg/100m1 sauce), 4519.5(mg/100m1 sauce) after fermentation. Hypoxanthine was revealed as the major constituent among nucleotides and their related compounds through fermentation. Free amino acid-N in the filefish scrap sauces were from 56.3%(ordinary) to 60.7%(low salted) of extractive nitrogen. From the sensory evaluation, the quality of products from filefish scrap sauce were almost equal to sold soy sauce on the market.

In order to investigate the utilization of the Omija (Schizandra chinensis Baillon) extract as a natural coagulant for manufacturing soybean curd, the quality characteristics of white (Baktae) and black (Seoritae) soybean curds, coagulated by the Omija extract or $MgCl_2$, were evaluated. Crude protein ($6.14{\pm}0.30$ and $6.25{\pm}0.18%$, respectively) and crude lipid ($10.86{\pm}1.74$ and $11.29{\pm}1.69%$, respectively) contents of white and black soybean curds coagulated using the Omija extract were higher than those coagulated using $MgCl_2$. Black soybean curds coagulated using the Omija extract showed higher L, a, and b values than those using $MgCl_2$. The most abundant amino acid in white and black soybean curds coagulated using the Omija extract was arginine (3.74 and 3.71 mg/100 g, dry basis, respectively). The amounts of Ca, K, Mg, and Na were the highest in both soybean curds prepared with the Omija extract. The sensory evaluation (color, flavor, taste, texture, and overall preference) showed that white and black soybean curds coagulated using the Omija extract were more preferred than those produced using $MgCl_2$. The results suggested that using the Omija extract as a natural coagulant agent could improve the quality and sensory characteristics of soybean curds.
