  • This study was performed to investigate and assess the composition of mineral and macronutrient contents in Korean cow′s milk.48 individual farm raw milk, 10 plant raw milk and 29 market milk were collected from June to August in 2003. The minerals such as calcium(Ca), potassium(K), magnesium(Mg), sodium(Na), zinc(Zn), iron(Fe) and phosphorus(P) were determined by using atomic absorption spectrometer(AAS). The macronutrients such as fat, protein and lactose were tested by using IR spectrometer. The obtained analytical results of minerals(mg/100 g) and rnaetronutrients (%) are as follows:1. In case of raw cow′s milk ; Ca 113.56, K 144.09, Mg 10.86, Na 42.53, Zn 0.42, Fe 0.030, p 113.32, fat 3.85, protein 3.08, lactose 4.80,2. In case of market cow′s milk ; Ca 103.04, K 142.46, Mg 10.27, Na 43.21, Zn 0.40, Fe 0.034. p 97.30, fat 3.78, protein 3.05, lactose 4.70,3. In case of fortified market cow′s milk ; Ca 165.40, K 145.79, Mg 10.57. Na 42.55, Zn 0.57, Fe 0.414, p 94.68, fat 3.74, protein 3.08, lactose 4.68,4. In case of processed market cow′s milk ; Ca 134.72, K 142.74, Mg 10.33, Na 45.07, Zn 0.50, Fe 0.650, p 92.48, fat 3.72, protein 3.07, lactose 4.74. According to the group of market milk(milk, fortified market row′s milk, processed market cow′s milk), the mean concentration of Ca and Fe were significantly higher in fortified and processed milk than milk(p<0.05). There were no significant differences in macronutrient(fat, protein, lactose) and mineral contents between pasteurized milk and UHT(ultra high temperature) treated milk($\alpha$=0.05). The labeled "Nutritional Facts" of market milk were satisfied with "Labeling Standards for Livestock Products of Korea". The measured mean concentrations of Ca, Fe, Zn were generally higher than lower limit of labeled value(above 80% of labeled value). The mean concentration of sodium was lower than upper limit of labeled value(below 120% of labeled value).

  • To evaluate the effect of feeding time and high fat diet on weight gain and blood components in rats, the classification of groups were night(P.M. 8:00-next day A.M. 8:00), day(A.M. 8:00 P.M. 8:00) and ad-libitum(24 hours)group as feeding time. Each group has also 2 groups by fat level(high-fat diet, standard diet). Therefore, the 36 experimental animals were divided into 6 groups. The results of this study can be summarized as follows. Food intake of SA(standard diet / ad-libitum) and SN(standard diet/night) groups was significantly higher than the others, and HA(high fat diet /ad-libitum) and HD(high fat diet /day) groups was significantly lower than the others. Body weight gains of HN group and SA group were significantly higher than the others in 5 weeks. The blood contents of total cholesterol, triglyceride, protein and albumin were no significant difference among experimental groups, but the blood contents of glucose were higher in HN and SD groups than SN and HA groups. Accordingly, eating before asleep and high fat diet bring about one's overweight and abnormal blood concentration.

  • Objectives : This study was performed to investigate the change of bone mineral density(BMD) after 1 month Kirindiet therapy including very low calory diet(VLCD) in middle-aged obese women$(65>age{\geqq}40,\;BMI{\geqq}25)$ under normal $BMD(T-score{\leqq}0)$. Methods : We examined body weight, body fat, protein mass and BMD of 13 middle-aged obese women who visited to Kirin Oriental Hospital from Sep. 7. 2004 to Oct. 12. 2005 before and after 1 month Kirindiet therapy. Body weight, body fat and protein mass was checked by Inbody 4.0 and BMD was checked by quantitated computed tomography. Wilcoxon signed rank test was used for analyzing changes of body weight, body fat, protein mass and BMD before and after treatment. Results : Alter 1 month treatment body weight(-4.89Kg, -6.74%, p=0.001), body fat(-3.47Kg, p=0.001) and protein mass(-0.97Kg, p=0.006) was significantly reduced. BMD was significantly increased in all cases(+4.87mg/cc, +4.16%, p=0.001). Though body weight, body fat and protein mass were significantly reduced, BMD was significantly increased(p<0.01). Conclusions : In this study, we can conclude that after 1 month Kirindiet therapy including VLCD, BMD in middle-aged obese women under normal BMD was significantly increased inspite of reduction of body weight, body fat and protein mass.

  • Background: A reasonable weight reduction is to reduce fat-body mass while preserving free-fat mass. Recently, many people in Korea have been trying reckless diet therapy for weight reduction by low calory and protein diets, which gave rise to many side effects consequently. For reasonable weight reduction, this study was undertaken to investigate the influential diet factors that change body composition during short-term low calory diet. Methods: 26 healthy obese women aged 23-27 years whose BMI was greater than 24volunteered for the 6 week diet therapy from January to April in 2003. All subjects were instructed to eat approximately 1200kca1/day and write dietary diary. In the beginning of the study, the 3rd week and the 6th week, subjects' body weight and fat body weight were measured by BlA. In the 6th week, the analysis of dietary diary was conducted. Results : There was significant positive correlation between protein intake per ideal bodyweight in the first 3 weeks and free fat mass increase in the later 3 weeks (P<0.05). At the same time, fat intake in the first 3 weeks had positive correlation with free fat mass in the second 3 weeks, too(P<0.05). But, we could not find any significant values that had effect on free fat mass increase in multiple regression analysis. Conclusion: The protein intake in the first 3 weeks helps preserve fat free mass in the later 3 weeks, and has positive effects.

  • 산양유의 계절별 및 농장별 이화학적 특성을 구명하기 위하여 본 연구의 결과 및 타지역에서의 산양유 성분인 Fat, Protein, Lactose, Total Solid, SNF, Cells 성분 등을 살펴본 결과 $12{\sim}6$월 사이의 값 중에서 2월과 3월에 Fat, Protein, Lactose, Total Solid, SNF, Cells 값이 높은 경향을 보였고, 특히 Fat의 경우 $12{\sim}3$월까지의 값이 다른 월별 성분보다 더욱 높은 값을 보였다. SNF의 경우도 2월에 다른 월별 성분보다 월등히 높은 값을 나타냈다. 그러나 Lactose는 계절 또는 월별간 큰 차이를 보이지 않았다. 산양유 성분의 지역별 차이 또한 크지 않았으며 일반 유성분 자료를 본 연구의 결과와 참고자료를 함께 비교 검토한 결과 산양유의 일반조성은 cow milk와 전체적으로 비슷하나 Fat 성분에서 약간 낮은 값을 보였고, Mare milk 보다는 전체적으로 높은 값을 보였다. 산양유 생산은 산양의 계절번식에 의한 계절간 생산량의 편차가 커 수급조절이 어려운 문제점이 있으므로 국내 산양유 산업의 발전을 위해서는 산양유 제품의 소비를 촉진시킬 수 있는 저장성이 우수한 다양한 기능성 제품을 고안하여야 한다고 사료된다.

  • The purpose of the present study was to investigate effects of kochujang and red pepper on energy intake, body fat content and energy expenditure in rats fed on high-fat(30%) diet. Kochujang and red pepper power were added in the high-fat diet, adjusting the level to 95 and 22g/kg diet, respectively, The level of red pepper addition was corresponding was corresponding to the level of the content of red pepper powder in the kichujang-added diet. Kochujang induced a 30% reduction in body fat gain which was associated with a significant increase in energy expenditure. However, red pepper reduced body fat gain by only 15%. Furthermore, energy expenditure was not affected by red pepper. Metabolizable energy intake, apparent digestibility and body protein gain were not affected by either kochujang or red pepper. It has been known that capsaicin, a pungent component of red pepper, enhances activity of brown adipose tissue through increasing protein content. In the present study, in addition of protein content, DNA content of interscapular brown adipose tissue was also increased by kochujang. Therefore, it appeared that the anti-obesity effects of kochujang was greater than those of red pepper, indicating more than red pepper was involved in the expression of the anti-obesity effects of kochujang(Korean J Nutrition 33(8) : 787-793, 2000)

  • This study was designed to investigate the associations of the percent body fat dietary intake, plasma lipoprotein profile, lipoprotein(a), and plasminogen activator inhibitor-1(PAI-1) concentrations of 1982 Korean subjects(men : 1000 and women : 982) between the ages of 40 and 59 years. The dietary assessment consisted of twenty-four hour dietary records and food frequency questionnaires. The subjects were identified into one of the five rating groups of % body fat : lean, underweight, normal, overweight and obese groups. The biochemical assessment included measurements of plasma total cholesterol(TC), HDL-cholesterol(HDL-C), LDL-cholesterol(LDL-C), triglyceride(TG), lipoprotein(a)(Lp(a)), and PAI-1. With respect to the ratio of percent energy intake of carbohydrate : protein : fat of the normal group of the women was 62% : 17% : 20%, respectively. Women apparently had a higher intake of carbohydrates than men(52% : 17 : 20%) did. There was a linear relationship between energy intake and % body fat in both mean and women(with the exception of the underweight group of women). The relationship of % body fat of men to the protein and fat intake was higher than that of the carbohydrate intake. Of the men in the study, intakes of energy, protein and alcohol were positively correlated to % body fat. In women, energy, carbohydrate and protein intake were positively correlated to % body fat, however, the fat, cholesterol and alcohol intake did not show any correlation to the % body fat in women. This study showed that % body fat was positively correlated with plasma TC, LDL-C, PAI-1 levels, and TG, but the % body fat was negatively correlated with plasma HDL-C level in both men and women. These results indicated that the high energy intake of obese or overweight subjects might contribute to several of the biochemical indices fo coronary heart disease(CHD) risk. In conclusion, increased energy intake is associated with overweight or obesity in middle aged Korean people. There was no relationship between % energy intake of fat and % body fat in the study, in middle-aged Korean men and women. The plasma lipid profile and PAI-1 level thought to be the risk factors of CHD were positively associated with percent body fat in middle aged Korean people.

  • Objective: The current study was carried out to examine the response of different levels of fat and protein in calf starter on nutrient utilisation, nitrogen metabolism, weight gain, blood parameters, and immunity level in pre-ruminant calves. Methods: Twenty four calves (5 days old) were divided into six groups in a 2×3 factorial design, with two levels of fat (10% and 14%) and three levels of protein (18%, 21%, and 24%). The calves were kept in individual pens for 120 days and fed with whole milk (1/10th of body weight) and calf starter ad-libitum. Daily dry matter intake was recorded; whereas body weight was taken on fortnightly basis to calculate average daily gain. During the growth trial blood samples were collected at 30 days interval to estimate blood glucose, albumin, total protein, total leucocyte count, total immunoglobulins and immunoglobulin G levels. A metabolic trial of seven days was carried out to find out the digestibility of different nutrients. Results: The dry matter intake was reduced (p<0.05) with higher fat and protein levels whereas feed conversion efficiency was improved (p<0.05) with higher protein level. Different levels of fat and protein in calf ration did not affect average daily gain in calves. The dry matter, organic matter, and crude protein digestibility were significantly (p<0.01) higher with increased level of protein. The nitrogen retention was also significantly higher (p<0.05) at 24% protein level, similarly the total immunoglobulin was significantly (p<0.05) high in higher protein fed groups, showed better immunity. Conclusion: The present finding suggested that 10% fat and 18% protein level of calf starter could be used in Sahiwal calves for optimum performance in terms of weight gain and immunity.

  • Fish sarcoplasmic protein (SP) obtaining from lyophilization was evaluated its effect on the qualities of the no-fat chicken sausages in the presence of microbial transglutaminase (MTG) as compared to sodium tripolyphosphate (STPP). The cooking yields of all sausage samples were not different. Expressible moisture (EM) of sausage samples was reduced by adding fish SP, while the lowest EM values were observed in sausage samples containing STPP. The pH values of sausage samples were increased with the addition of fish SP and STPP. Proximate analysis revealed that the moisture, fat, and protein contents of all samples were not different (p>0.05). Textural properties (TP), measured by texture profile analysis, showed that hardness of no-fat sausages increased upon adding fish SP. However, the highest TP values were found in sausage samples with STPP. The redness values were reduced in sausage samples with STPP, while other color values were not affected by STPP. Sensory evaluation revealed that sausages with fish SP were accepted at the higher level than that of control. However, sausage samples with STPP showed highest TP and acceptability. Thus, partial substitution of STPP by SP would be possible to reduce phosphate level in the chicken sausages.
