  • This study is to investigate effects of green tea and capsulated components mixture on body fat and serum lipid composition and fat distribution in college women students in terms of supplemented periods. During 3 months of this research, 34 college women students (average age 20.3 yr) were selected as subjects. Nutrient intake was investigated by questionnaire and 24-hr recall method. Anthropolatric assessments of the subjects were investigated by SBIA method (Segmental Bioimpedance Assay, Inbody 3.0). The results were as follows: mean body height was 162.5cm and mean body weight and mean BMI (Body Mass Index, kg/$m^2$) were 57.9kg and 21.9, respectively. Status of carbohydrate intake decreased significantly (p<0.05) and dietary fiber intake increased significantly (p<0.001) after supplementation. WHR (waist-hip ratio) decreased significantly (p<0.05) and body fat and percent body fat decreased significantly after supplementation (p<0.05). Total cholesterol and triglyceride decreased significantly after supplementation (p<0.001). Above results of this study show that green tea, silk peptide and dietary fiber supplementation-added routine diet improves body fat distribution, total cholesterol, triglyceride. Especially, declination of abdominal fat and WHR was notable, since that means diminution of risk factors for obesity and chronic degenerative diseases.

  • Oxygen consumption (OC), ammonia nitrogen (AN ) excretion and body composition were measured to study the effects of energy/protein ratio (EPR) on the utilization of protein and energy in juvenile rockfish, Sebastes schiegeli. Juvenile rockfish were divided into three groups that they fed three isocaloric diets (3,5kcal/g) containing 30 (I), 40 (II) or $50\%$ crude protein (III). EPR of the three experimental diets were 11.5 (I), 8.7 (II) and 7.0kcal/g III), respectively. Juvenile rockfish (wet wt. 2.9-3.1g) were cultured in 501 aquaria with the constant environmental condition of $20-24^{\circ}C$ water temperature and $34\%o$ salinity. For 24 hr after feeding the diets, juvenile rockfish fed diet III had a higher OC than did the fish from groups fed diets I and II, and average OC of the fish fed diets I, II and III were $0,93\pm0.02^a,\;0.92\pm0.02^a\;and\;1.03\pm0.03^bml\;O_2/g/h$, respectively. AN responses of juvenile rockfish to increasing levels of dietary protein (decreasing dietary EPR) were significantly different among three groups in which dietary protein at elevated levels increased the excretion of AN for 24 hr after feeding the diets. Average AN excretion of the fish fed diets I, II and III were $9.14\pm0.39^a,\;12.41\pm 0.53^a\;and\;14.89\pm0.55^c\;{\mu}g\;N/g/h$ respectively. The body protein content of the fish fed diet II for 59 days was significantly higher than that of the fish fed the other diets. But, there were no significant differences between three groups in body lipid, carbohydrate and ash contents. These results indicate that EPR of 9.7kcal/g (diet II) could be a optimum EPR in juvenile rockfish diet.

The result of the survery is as follows: 1) Among the above pregnant women, primigravida constituted 91 women and multigravida 92 women. As for the month of pregnancy, those who have been pregnant for ten months numbered 43 women (23.5%), which was the highest number. As for age, those who were 25 to 29 years old constituted 63.9% , which was the highest in percentage. 2) As for the level of education, those who graduated from high school constituted 49.2%, which was the highest in percentage. As for occuptation, those who were entirely in charge of household affairs as housewives were 89.6% , which comprised most of the jobs held by the above women. 3) As for the composition of a family in environmental food and nutrition, one generation was 68.3%, and two member family was 42.6% which was the highest. As for those taking rare of cooking and serving meals, housewives constituted 95.1%. 4) As for the economic situation of dietary life, those who were in the highest level (A level), were 47.0% in an urban area and 41.0% in a rural area, which were the highest in percentage. 5) The food which the above people selected after being pregnant was fruit not only in an urban area, but also in a rural area. And in terms of the percentage of fruit, an urban area and a rural area showed 44.0% and 54.2% respectively. As for milk, and urban area and a rural area showed 28.0% and 8.4% respecitively, which disclosed that the rate of a rural area was much lower than that of an urban area. 6) As for the number of food intake, 10-14 was 54.0% in an urban area, which was the highest. And 5-9 was 73.5% in a rural area, which was the highest. 7) As for the composition of food taken according to the number of food taken, meat showed the lowest rate in 5-9 group. (p<0.05) As the number of food taken increased, the rate of food taken (points) increased (2.4). Milk and milk products showed a low rate in 5-9 group and 15-19 group (p<0.05). Fruit intake showed a similar rate in all groups. As for vegetables, the rate of intake was high, as the number of food taken increased. Cereals showed a similar rate in all groups. Ans the points of intake was high. As for fat, the rate of intake was high, as the number of food taken increased. 8) In 5-9 group in the number of food intake, energy was 79.9% of RDA, protein was 64.9%, fat was 90.0%, carbohydrate was 81.6%, iron was 83.0%, calcium was 71.1%, vitamin A was 94.3%, vitamin $B_1$ was 77.8%, vitamin $B_2$ was 79.2%, and vitamin C was 88.2%, so that it showed the lowest sufficiency rate RDA. 15-19 group maintained the balance in energy and all nutrients nealy.

  • In order to investigate the effect of dietary protein and energy on growing female and male rats, Sprague-Dawley 90 female rats and 54 male rats of 3 weeks old weighing approximately 70-80g and 65-75g, respectively, were subjected to feeding trials for 8 weeks and then subsquently to metabolic trials for 2 weeks. Three dietary energy levels (3200, 3600, 4000 kcal ME/kg) were employed and each energy level contained three protein levels (15, 25, 35% of 3600 kcal ME/kg) and three fat levels (10, 20, 40% of 3600 kcal ME/kg) by addition of an appropriate amount of carbohydrate and the following results were obtained. The body weight gain of female rats was highest for LPHE ration but that of male rats was highest for LPME ration. The weight gains both of female and male rats were not affected by the level of protein. Food efficiencies both of female and male rats was affected by the level of protein, whereas that of male rats was not. Protein efficiencies of female and male rats were highest at low protein level and tended to decrease as the level of protein increased, but that of female rats was highest at high energy level, while that of male rats was highest at medium energy level. The analysis of the body composition after feeding trials for 8 weeks has shown that the contents of body water and protein were not affected by protein level both in female and male rats. The content of body fat increased remarkably as the protein and energy levels increased in case of female rats, but it was not affected by the protein and energy levels in case of male rats. From the above-mentioned experimental results it may be con eluded that the best formula of diet of growing female rats may be composed of low protein (13%) and high energy levels (4000 kcal/kg) whereas that for male rats may be composed of low protein (13%) and medium energy levels (3600 kcal/kg), since all the efficiencies of food, protein and energy have shown to be best at these levels.

  • The purpose of this study was to analyze health-related habits, weight control experience and body composition of 344 female students visiting nutrition counselling office. Dietary habits of the subjects were assessed by means of interview with questionnaire and nutrient intakes were evaluated by the simple dietary assessment method. Weight and height were measured to get body mass index(BMI) and waist-hip ratio and their body composition were measured by Inbody 3.0. The obtained results were as follows: 1) Among students, 14.5% were exercising on a regularly basis, of which the exercises were walking and gymnastic exercise(22.1%), jogging(14.1%), and rope-skipping(4.7%), 48.4% of students were little drinking and 30.5% were once a week and smokers were 4.1%. 2) 28.3% of students were little having breakfast and 15.1% were once or twice a week. Two third of total students were not having breakfast regularly. Also only 59.6% of students were having dinner everyday, which means many of them were even skipping dinner. The reasons why they were not having breakfast were because they don't have enough time to eat(66.0%) and for a diet(2.8%) and the reasons for skipping dinner were because they were not hungry(23.0%), for the weight loss(18.2%). It was shown that they would skip dinner rather than breakfast for a weight control. 51.6% of students were taking snack 1~2 times a day and 5.3% were having little snack. 55.4% of students were dining out once a day and 15.4% more am 2 times a day. 3) 46.7% of students were already experiencing weight control before visiting the counselling office. 78.5% of students tried on one kind of weight control method, 11.4% on two kinds, and 10.1 % on more than three kinds. The method they tried for a weight control most was the one food diet using egg, fruits and beans, which is the most popular among them, and the next were an aerobic exercise(23.6%). a diet tried by a famous entertainer (15.5%), and the fasting(14.5%). 4) The average BMI was 21.2 and the body fat rate was 28.1%. As a result of grouping BMI, 12.8% were underweight 67.6% normal weight 11.6% overweight and 8% obesity. Less than standard for the body fat rate were 0.6%, 50.6% standard, 48.5% more than standard. 49.2% of students as normal weight on a BMI were assessed the so-called "skinny obesity. 50% of consulted students situated fat intra-abdominally at the umbilical level(WHR>0.8). 5) The energy intake was 76.6$\pm$17.8% of RDA and constituent ratio of carbohydrate, fat and protein were 64.2$\pm$5.2%, 21.6$\pm$3.7% and 14.3$\pm$2.3%, respectively, which is little over of 20% of recommended ratio of fat. Protein and niacin intake were more than 90% of RDA and riboflavin and vit. C were taken more than 100% of RDA. But Fe intake was 69.4$\pm$19.3%, Ca 76.6$\pm$23.6%, which were the least constituents. There was not remarkable significance between energy intake and nutrient density based on the groups of underweight, normal weight, overweight and obesity of BMI. 6) It was shown that body fat rate had remarkably significant correlation(p<0.000) with BMI(r=0.760) and WHR(r=0.817) respectively, but body fat rate was more correlated with WHR than with BMI. There was not much significant difference between body fat rate and WHR whether they exercised or not. However. BMI was significantly higher in the exercise group because one who showed higher BMI started to exercise since they looked fat in appearance and perceived as they were fat. fat.

  • This study was performed to investigate the physicochemical properties of sea urchin ($Anthocidaris$ $crassispina$, $Pseudocentrotus$ $depressus$, $Hernicentrotus$ $pulcherrimus$) roe as a processed or canned food by steaming treatment. Proximate compositions of $A.$ $crassispina$ roe and $P.$ $depressus$ roe were similar, but water, crude ash, and carbohydrate contents of $H.$ $pulcherrimus$ roe showed little differences. Proximate compositions of sea urchin roe showed slight differences with steaming time, raw samples showed no differences. Glycine content of the three raw sea urchin roe samples showed the highest concentration among free amino acids, followed by arginine, alanine, and lysine, in order. Total free amino acid contents of raw sea urchin roe were 754.70 mg% ($A.$ $crassispina$), 567.75 mg% ($P.$ $depressus$), and 449.44 mg% ($H.$ $pulcherrimus$). Total free amino acid content of 5 min steaming sample was highest among steaming and canning conditions. ATP, ADP, and AMP contents of raw $P.$ $depressus$ roe sample was higher than those of $A.$ $crassispina$and $H.$ $pulcherrimus$ roe. Major fatty acids of the three raw sea urchin roe samples were myristic acid, palmitic acid, and EPA. S.F.A. content of raw samples of $A.$ $crassispina$and $H.$ $pulcherrimus$ roe was higher than U.F.A content, whereas U.F.A. content of $P.$ $depressus$ roe was highest among the three raw samples. For minerals K, P, Fe, and Zn contents were highest in $A.$ $crassispina$roe while Ca, Mg, Na, and Cu contents were highest in $H.$ $pulcherrimus$ roe. For heavy metals, Cd, Pb and As were detected in all samples in trace amounts under the criteria of the Korea food codex.

  • Opuntia humifusa fruits were investigated. The length of minor and major axis, and weight of O. ficus-indica and O. humifusa fruits were compared as the morphological features. The characteristics of components such as color, moisture, crude protein, ash, fat, dietary fiber, mineral, and amino acids were evaluated. The values of O. ficus-indica fruits were higher than those of O. humifusa fruits in each morphological feature such as minor axis, major axis, and weight. According to the Hunter color index results, O. humifusa fruits showed higher values of L (lightness) and b (yellowness), whereas O. ficus-indica fruits showed higher value of a (redness). The ${\Delta}E$ value between two samples was 19.80. The O. ficus-indica fruits had higher carbohydrate content and lower content of crude ash than those of O. humifusa fruits. Both samples showed very high dietary fiber contents, and the major minerals were K and Ca. Glutamic acid was the major amino acids in both samples. In free amino acids contents, O. ficus-indica had higher tyrosine and lower glutamic acid level than those of O. humifusa fruits. ${\gamma}$-aminobutyric acid was found in both samples, whereas taurine was found in O. ficus-indica fruits only. Taken together, the morphological features and chemical quality of O. ficus-indica and O. humifusa fruits showed difference although both of them were originated from the same genus.

  • The purpose of this study is to investigate the various functionalities of the peels, pulps, and seeds of passion fruit. Proximate composition, mineral contents, phenolic acid contents, total polyphenols, total flavonoids, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities, 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities, reducing power, α-glucosidase, and α-amylase inhibitory activities were measured for each part of passion fruit. Proximate composition analysis of the passion fruit indicated that moisture content contained (4.78-8.20%), carbohydrate (68.33-73.23%), protein (8.78-13.63%), fat (1.19-11.60%), and ash (1.51-8.80%). K, Ca, Na and Fe were the predominant mineral in the peels. P and Mg were the predominant mineral in the pulps. All the antioxidant activities (total polyphenols, total flavonoids, DPPH radical scavenging, ABTS radical scavenging, and reducing power) showed high results in the seeds. α-Glucosidase and α-amylase inhibitory activities IC50 were in the peels (5.59 and 63.16 mg/mL), in the pulps (3.80 and 31.90 mg/mL), and in the seeds (0.06 and 1.02 mg/mL). These results indicated that the pulps, peels, and seeds of passion fruit have value as natural antioxidants with the high quality functional components.
