This study is conducted to compare the problems affecting dietary habits and health status between a long-term exercise group and non-exercise group of males older than 50 years. Most subjects of the two groups consider regular exercise to be the most important factor for maintaining health, and recognize hypertension as the number one concern. The most common nutritional supplement among subjects is multiple vitamins, and sleeping time range from 6~8 hours. Breakfast fasting rate was 15.9% among non-exercise group (NEG), where overeating and eating out rates were higher among exercise group (EG) when comparing to NEG. Fasting rates of breakfast, and consumption rates of milk and dairy products, vegetables such as kimchi, and fruits and fruit juices are higher among the EG. Overeating and eating out rates are lower among NEG, whereas eating rates of proteins like meat, fish, eggs, beans, fried foods, high-fat meats carbonated drinks, ice cream, and salt intakes are higher. Rates of health, dietary habits, and nutrient intakes are higher among EG. Energy intakes among the two groups were below the standard level, Vitamin B2 intake is low in EG, and folic acid and calcium intakes were higher in NEG. The exercising group care more about health, eating habits and nutrient intakes, and low smoking rates are being observed. Thus, specific dietary improvement programs for adult men, are required, and it is necessary to consider the practice of nutrition education.

본 연구는 혈압 강하, 비타민 B1의 활성화, 항암 효과, 노화방지 등에 탁월한 효과가 있다고 알려진 마늘의 활용도를 더욱 높이기 위하여 중력분에 수준별(1%, 3%, 5%) 마늘 분말을 첨가하여 물성 변화 및 마늘가루 첨가가 제면 적성에 미치는 영향을 실험하였다. 마늘 분말 첨가량을 달리하였을 때 호화도 변화를 측정한 결과, 마늘 분말 양이 증가하면 호화 개시온도가 높아졌으며, 최고 점도는 낮아졌다. 최고 점도와 최저 점도의 차이를 나타내는 breakdown 값도 낮아졌다. 또한 최종 점도도 약간 낮아지는 경향을 보였으며, 마늘 분말 첨가량이 증가하면 set back값은 감소하는 경향이었지만 노화를 억제할 정도는 아니었다. Farinogram의 consistency는 마늘 분말 첨가량이 많아질수록 높아졌고, 수분흡수율 또한 높아지는 경향을 보였다. 반죽형성시간은 길어졌으며 안정도는 낮아졌으며, 마늘 분말 첨가량이 많아질수록 time to breakdown 값이 급격하게 떨어졌다. Mechanical tolerance index 값이 마늘 분말 첨가 시료들의 경우 낮게 나타나, 마늘 분말을 첨가하면 반죽의 기계적 적성이 떨어진다는 것을 알 수 있었다. Farinogram quality number는 중력분 대조구에 비하여 마늘 분말 첨가구들은 첨가량이 많아질수록 그 수치가 떨어졌다. 그러나 1% 첨가구와 3% 첨가구 사이에서는 서로 간에 유의적인 차이를 보이지 않았다. Alveogram을 이용하여 글루텐 강도를 측정한 Pmax 값은 마늘분말 첨가량이 많아질수록 Pmax 값이 감소되었을 뿐만 아니라, 서로 간에 유의적인 차이를 보이지도 않았다. 팽창된 반죽이 터질 때까지의 신장성을 나타내는 L값은 마늘 분말 첨가량이 증가하면 감소하였다. 그러나 3% 첨가구와 5% 첨가구 사이에서 유의적인 차이는 나타나지 않았다. 팽창지표를 나타내는 G값 역시 마늘 분말 함량이 많아지면 G값은 낮아졌다. 하지만 3% 첨가구와 5% 첨가구 사이에서는 L값과 마찬가지로 유의적인 차이를 보이지 않았다. 변형 에너지 값인 W값도 마늘 분말 첨가량이 증가하면 W값은 감소하였으며, 특히 대조구에 비하여 마늘 분말 1% 첨가구는 급격하게 수치가 낮아졌다. 3% 첨가구와 5% 첨가구 사이에서는 유의적인 차이를 보이지 않았다.

This study estimates the classification criteria which distinguishes the types of omega-3 health functional foods, fish oils and fish oil usages through 13C-NMR spectra and fatty acids contents analysis. The major fatty acids of omega-3, eicosapentaenoic acid (EPA, C20:5) and docosahexaenoic acid (DHA, C22:6) are being analyzed. 10 ethyl ester (EE) forms and 10 triglyceride (TG) forms are the most common types of fish oils for 20 omega-3 products. Gas chromatography (GC) analysis generally shows the matching EPA and DHA contents of the products listed on the notation. But EE form contents of EPA and DHA are higher and are more varied than the TG form. Most of the samples of EPA/DHA ratio show different content ratios of indicated on the products when comparing with standards. The 13C-NMR analysis of EPA and DHA on sn-1,3 and sn-2 carbonyl peak position with fish oil triglycerides display whether the reconstituted triglycerides (rTG) are being confirmed or not. As a result of the 9 TG form, the 10 TG products showed similar values: EPA sn-1, 3; 13.46~15.66, sn-2; 3.00~4.52, DHA sn-1, 3; 2.43~4.40, sn-2; 3.84~6.36. But one product showed lower contents (EPA: sn-1, 3; 5.88, sn-2; 2.86, DHA sn-1, 3; 2.29, sn-2; 5.95) of EPA, thus it can be considered a different type of oil and only matched six products according to the label. This study is intended to provide basic materials which identify the status for the types and quality of omega-3 fish oil products according to fatty acids profiles and the 13C-NMR spectrum confirmed the location specificity of EPA and DHA.

The study was conducted to investigate the condition for mixed fermentation of Rhodilola sachalinensis with red ginseng using Lactobacillus acidophillus 128 and the changes of physicochemical properties and antioxidant activities before and after the lactic acid fermentation was examined. In the single fermentation of Rhodiola sachalinensis extract, the pH and titratable acidity rarely changed, and the number of lactic acid bacteria decreased greatly. On the other hand, in the lactic acid fermentation of Rhodiola sachalinensis-red ginseng mixed extract of 50% red ginseng content, the pH decreased, whereas the titratable acidity and the number of lactic acid bacteria increased. The solid content of optimal mixed extract for lactic acid fermentation was 0.5%. Sugar content decreased during fermentation, but total phenolic compounds tended to increase during fermentation. The salidroside and p-tyrosol content of the initial Rhodiola sachalinensis-red ginseng mixed extract was 419.5 ㎎% and 60.1 ㎎%, respectively; after fermentation, the salidroside content after lactic acid fermentation decreased greatly to 81.8 ㎎%, and the amount of p-tyrosol increased greatly to 324.9 ㎎%. The DPPH scavenging activity of Rhodiola sachalinensis-red ginseng mixed fermentate was 78.1% at 0.1% concentration, showing a tendency to increase as compared to 50.3% of Rhodiola sachalinensis-red ginseng mixed extract before the fermentation (p<0.05); it was a higher antioxidant activity as compared to the single fermentation of Rhodiola sachalinensis or red ginseng.

The present study is designed to explore an anti-tumor activity on crude extracts of Oplopanax elatus. Water extractions of Oplopanax elatus were performed at 100℃(OeE-100). OeE-100 doses up to 62.5 ㎍/㎖ had no cytotoxicity on the tumor cell lines in vitro. In experimental lung metastasis of colon26-M3.1 carcinoma or B16-BL6 melanoma, the prophylactic intravenous (4~100 ㎍/mouse) or oral (2 ㎎/mouse) administration of OeE-100 significantly inhibited tumor metastasis as compared with tumor controls. Peritoneal macrophages stimulated with OeE-100 produced various cytokines such as TNF-α, IL-6 and IL-12. In an analysis of NK-cell activities, i.v. administration of OeE-100 (10~100 ㎍/mouse) significantly augmented the cytotoxicity to YAC-1 tumor cells. Vaccination of mice with boiling-treated tumor cells (BT-vaccine) in combination with OeE-100 (100 ㎍/mouse) showed higher inhibitions in tumor metastasis when compared with the mice of BT-vaccine treatment. In addition, the splenocytes from OeE-100 admixed BT-vaccine immunized mice secreted a higher concentration of Th1 type cytokine such as IFN-γ. These results suggested that the OeE-100 stimulated immune system and was a good candidate adjuvant of anti-tumor immune responses.

This study investigated the knowledge, attitude, and behavior of 280 University students towards nutrition labels. The purpose of the study was to examine knowledge, attitudes, and behaviors of university students regarding nutrition labeling, and whether body mass index (BMI) with nutrition labeling was associated with knowledge, attitudes, and behaviors. Descriptive statistics analyzed knowledge, attitudes, and behaviors of university students regarding food labeling. The ANOVA and χ2 analysis was evaluated and assessed for its relationship with BMI. Pearson's correlation coefficient analysis examined relationships between knowledge, attitudes, and behaviors. More than 90 percent of answers relating to 11 nutritional knowledge questions were correct. Only 30% of participants answered correctly regarding questions about plan source oil and cholesterol content. Attitudes and behaviors of nutrition labels were significantly higher among participants who were obese (p<0.001). Knowledge score was positively correlated with general label usage behavior (r=.169, p<0.01), and item buying behavior (r=0.142, p<0.05). Attitude also was positively correlated with behavior (p<0.01). Nutrition labeling education efforts are needed to provide university students with a nutritional education program and information on how to read nutritional labels and apply this information to their lives. University students need to understand their need for numerous nutrients instead of merely focusing on the fat and calories of foods.

The results of testing general components, physical property and physical function after having made steamed rice cake by adding eggplant, which caters to consumers’ tastes are as follows. It showed that when eggplant powder content increased, the moisture content of steamed rice cake with eggplant was decreased. It also showed that the lightness value (L) of steamed rice cake with eggplant powder was the highest as 82.75 in the control group. When eggplant powder content increased, the redness (a) and yellowness (b) were increased. From the results of having measured the antioxidant potential over the steamed rice cake with freezing-drying eggplant powder by DPPH radical elimination, we figured out that it was the lowest as 48.30% in the control group. As more eggplant powder was added, its elimination increased accordingly. As per hardness of steamed rice cake with eggplant, the added group with 7% was revealed as the highest at 0.757. It showed that adhesiveness was the lowest as 30.233 in the control group, and springiness and cohesiveness were on the rise as freezing-drying eggplant powder was increased. Furthermore, softness and chewiness were shown to be high in the added group with eggplant powder of 3, 5%. The evaluation over the overall preference was the highest in 5% added group. Judging from this, adding 3~5% eggplant powder against non-glutinous rice powder is considered an optimal quantity in making steamed rice cake with eggplant.

The physical properties of jellified soybean curd residue (Biji) with the addition of various gums were investigated to optimize the direct availability of a by-product of the tofu production process. The lightness (L value) of the jellified Biji prepared with various gums was approximately 77~80, regardless of the concentration of gum used. Especially at the concentration of 0.1% and 0.3%, a pectin showed a significantly higher value compared with other gelling agents (carrageenan and agar). The strength of samples prepared on the basis of carrageenan showed the value of 335~569 g/㎠ and 234~335 g/㎠ according to the addition of locust bean gum and xanthan gum, respectively. On the other hand, the samples made with pectin and agar were 134~272 g/㎠ and 50~215 g/㎠, respectively. Where locust bean gum was used as a viscous agent, the adhesiveness of sample prepared by adding carrageenan was greater than those made with pectin or agar. The values were －6.0~－11.0 g, －2.7~－10.2 g and －3.7~－7.0 g, respectively. Overall, the strength and adhesiveness of samples according to increase of the added amount of Biji showed constantly increasing trend regardless of the type of gelling agent used. In the sample containing carrageenan this trend was most noticeable.

Changes in Quality Characteristics of Pork Rectum by Addition of Maesil (Prunus mume Sieb. et Zucc.)
본 연구에서는 매실의 첨가에 따른 돼지막창의 품질특성 변화를 확인하였다. 가열하지 않은 막창(생막창)과 100℃에서 10분 동안 가열한 막창(가열막창)의 pH는 매실의 첨가에 따라 낮아졌다. L값과 a값은 생막창과 가열막창 모두 저장기간에 따른 변화는 미미한 것으로 확인되었다. 생막창의 b값은 저장 초기에는 매실의 첨가에 따른 상승이 확연하였으나, 저장기간이 지속됨에 따라 그 차이가 점점 줄어들었다. 가열막창의 b값은 매실의 첨가에 따른 b값이 약간 낮아졌으며, 저장기간에 따라 약간 감소하는 경향을 나타내었다. ΔT 값은 생막창과 가열막창 모두 L값과 거의 유사한 패턴을 보였다. 생막창과 가열막창 모두에서 TBA가는 매실의 첨가농도에 비례하여 유의적으로 낮아졌으며, 매실 5% 첨가구와 10% 첨가구는 거의 TBA가에서 차이가 없었다는 것으로 확인되었다. VBN가는 매실을 첨가할 경우 생막창과 가열막창 모두에서 VBN의 증가속도는 대조구에 비해서 낮은 것으로 확인되었다. 저장 6일째부터 매실의 첨가농도에 비례하여 VBN가가 낮아졌으며, 매실을 5% 첨가할 경우 저장을 4일 이상 지연시킬 수 있는 것으로 확인되었다.

This study was performed to estimate the salt content and evaluate the nutritional quality of free lunch meals served by welfare facilities for the elderly. We collected food items from 8 welfare facilities in Gyeonggi-do, and calculated the total salt content from the salinity and weight of individual food items. The average salt content from lunch meals was 5.68 g, which was over the recommended daily salt intake by the WHO. The greatest contributor to the salt content among the menu groups was soup and stew (37.5%). Soup, stew, deep-fried foods, and sauces were major sources of salt, while the most salty dishes were sauces, deep-fried food, salt-fermented food, and kimchi. The nutrient content was sufficient, except for calcium in both men and women, which was equal to approximately 1/3 of the dietary recommended intakes (DRIs) for Korean adults of their mean age. In addition, the index of nutritional quality (INQ) and nutrient adequacy ratios (NAR) of most nutrients were satisfactory, except for those of calcium and sodium. The INQs of calcium and sodium were 0.64 and 4.41, respectively, while the mean adequacy ratio of a meal was 0.95. These results suggest that multilateral efforts to lower sodium intake be considered and calcium sources be added, in order to improve the quality of meals served to the elderly at welfare facilities.

The objective of this study was to investigate the perceptions and purchase behaviors on foreign matters in food. For that, we conducted a survey of 348 adults living in a metropolitan area. Concern over the presence of foreign matters in food was a lower than that for other harmful factors such as heavy metals, BSE, harmful microbes and so on. 70% of respondents would not take the snack which was detected a rat’s head, including the manufacturer’s product and similar products with it after the foreign matter incident. In contrast, about of 54% respondents were willing to buy canned tuna after the incident. It is necessary to prepare more detail management and policy on foreign matters in food.

This study was conducted to investigate the anthropometric data, nutrient intakes and serum profiles in premenopausal and postmenopausal women living in Gyeonggi-do Province, Republic of Korea. The subjects were 49 premenopausal women and 63 postmenopausal women who are not taking any hormone or cardiovascular drugs. Anthropometric measurements were taken by a trained practitioner and the data for dietary intakes were obtained by a 24-hour recall method. Serum samples were collected and analyzed for the total cholesterol, triglyceride (TG) and lipoprotein fractions. The mean age of the premenopausal women was 45.17±3.28 years and that of the postmenopausal women was 62.52±4.14 years. The height and weight were 157.86±4.35 ㎝, 58.75±6.01 ㎏ in premenopausal women and 156.42±3.62 ㎝, 57.63±5.38 ㎏ in postmenopausal women, respectively. WHR (waist hip ratio) in postmenopausal women was significantly higher than that of premenopausal women (p<0.05). There were no differences between the pre-and postmenopausal women in the intakes of energy, protein, fat, Ca, Fe, vitamin A, vitamin B1, vitamin B2, niacin, vitamin C and vitamin E. However carbohydrate and Na intakes in postmenopausal women were significantly higher than those of premenopausal women. In postmenopausal women, Ca intake was below and Na intake was extremely high considering KDRIs (Dietary Reference Intakes for Koreans). Serum triglyceride in postmenopausal women was positively correlated with age, BMI (body mass index) and WHR. Serum total cholesterol and triglyceride in postmenopausal women showed significantly negative correlations with fiber intake. These results suggest that it is necessary to help postmenopausal women maintain a healthy body weight. Postmenopausal women needs to increase Ca (calcium) intakes and diet quality by decreasing the intakes of Na (sodium). In addition, an adequate intakes of fiber is recommended for postmenopausal women to prevent cardiovascular disease.
