This study is a survey of regulatees' perception on main contents and enforcement effect of the Act, the retailers at food stores within Green Food Zone, for the effective enforcement of “The Special Act on the Safety Management of Children's Dietary Life” legislated in 2008. Percentage, frequency analysis, and T-test are derived from the survey carried out to the 175 retailers at food stores within Green Food Zone, across the country except Jejudo, for the two months March and April of 2011. The survey results are as follows. Over 80% of the respondents are aware of comprehensive policy for child food safety and the enforcement of 'the Special Act' and considering the rate of satisfaction on food safety information provided by government, over 90% of the respondents, virtually most of them, are satisfied. The rate of awareness of Green Food Zone is about 80% and that of outstanding business for children is about 50%, showing little perception of it. The comparison of the survey result of 2011 with that of 2010, which have the same questions to the retailers within Green Food Zone, still indicates a need for enhancement of understanding on absolute standard, though it showed fairly better improvement in general. Several proposals are given in this study based on the survey results, which will contribute to the children food safety and health improvement in the end.

The purpose of this study was to investigate the dietary habits and snack consumption behaviors of middle school students with different obesity indexes in the Chungnam area. The survey was carried out using self-questionnaires and included 385 students(119 underweight, 193 normal weight, 66 overweight). The rate of skipping meals was higher for underweight students than overweight students; however, this difference was not statistically significant. The mean time of meal was 10 to 20 minutes and the criteria for choosing to eat a meal were ‘hunger’ and ‘taste’ in all groups. More than half of the subjects ate snacks 1 time a day, which were purchased outside. The typical snack time was ‘between lunch and dinner’. The criteria of for consuming a meal were ‘taste’ and ‘price’ in all groups. In the underweight group, the snack food scores were ice cream(4.4), fruit(4.3), fried chicken(4.1), sports beverage(4.0), fruit juice(4.0), pizza(4.0) and, tteokbokki(3.9). In the normal weight group, the snack food scores were ice cream(4.3), fried chicken(4.2), pizza(4.0), sports beverage(3.9), fruit juice(3.9) and, tteokbokki(3.9) in the overweight group, the snack food scores were ice cream(4.3), fruit(4.3), fried chicken(4.2), yogurt(4.0), sports beverage(4.0), fruit juice(4.0) and, ramen(4.0). In conclusion, the snaking behaviors of the subjects were not significantly different based on their obesity index. However, this study may provide basic information on the snacking behaviors of middle school students, and the findings suggest that nutrition education or counseling can improve snack intake habits and positive behaviors toward healthy adolescents diets.

This study was conducted to examine dietary behaviors according to residence status and ethnicity of university students in Yanbian, China. For the subjects, 334 university students (Male=141, Female=193) answered a questionnaire about perception of weight control, dietary patterns, health habits, residence status, and ethnicity. Perception of weight, meal frequency, favorite kind of food, meal finishing time, skipping breakfast, type of breakfast, snack frequency, late-night snack frequency, exercise frequency, regular life, and sleeping time were all significantly associated with residence status. Motivation of weight control, meal frequency, regularity of meal time, meal volume, favorite kind of food, exercise time, and regular life were all significantly associated with ethnicity. University students who lived with their parents perceived their weight more properly, exhibited a more positive dietary pattern, and lived a more regular life than those students who lived in a dormitory with their friends. Chinese students exhibited a more regular dietary pattern and lived a more regular life than the Korean-Chinese students. As a result, both environmental and inherent factors are related with the dietary behaviors of university students in Yanbian, China. These data could be used to help university students in Yanbian, China attain a healthy diet.

본 시험은 포도부산물의 첨가가 젖소의 산유량, 유성분 및 혈액 성상에 미치는 영향을 조사하기 위하여 실시하였다. 비유중기 젖소 8두(평균 월령: 89.8, 평균 유기: 164.4, 평균 산차: 2.8산)를 공시하였으며, 포도부산물을 첨가하지 않은 대조구와 1일 1 kg을 첨가한 시험구로 두 처리구를 설정하여 3주간 급여하였다. 유지방, 유단백, 유당 및 총 고형물 함량은 처리간에 차이가 없었다. 그러나 산유량은 포도부산물 을 첨가한 처리구가 23.13 kg/d으로 대조구의 21.16 kg/d에 비해 높은 반면(p<0.05), 체세포 수는 대조구가 포도부산물 처리구에 비해 높았다(p<0.05). 혈중 glucose, alanine aminotransferase, total protein 및 blood urea nitrogen 함량은 처리구간 차이가 없었으나, AST와 총콜레스테롤 함량은 대조구 (123.75 IU/L, 200.82 mg/dl)가 포도부산물 처리구(95.34 IU/L, 180.63 mg/dl)에 비해 높았다(p<0.05). 이상의 결과에서, 다양한 생리활성을 가진 포도부산물은 젖소를 위한 기능성 사료로 이용 가능성이 높을 것으로 사료된다.

We investigated the effect of glutathione supplementation on feed intake, body weight loss, behavior change and economic analysis of elk bull in breeding season. Sixteen elk bulls (5-year-old, average weight; 330 kg) after antler cutting were divided into 2 groups. Eight bulls in each group (control and glutathione group) were fed experimental diet at a level of 0.85 percent of body weight and 6 mg glutathione per kg body weight. As a result, weight-loss of control animal during experimental study (from September to November) was 42.6±19.2 kg while that of glutathione-supplemented group was 20.6 ±19.9 kg. Compared to control group, glutathione-fed group had prevented the body weight loss by 5.2% (p<0.05). Although the feed intake of elk voluntarily decreases during breeding season, daily DM intake per head was 5.59 and 5.80kg in control and glutathione-fed group, respectively. While the statistical difference in feed intake between two groups was not observed, feed intake tended to increase in glutathione-fed group. In economic analysis, additional cost of 99,000 KRW per head was spent due to the cost of glutathione because of its import. Changes in behavior such as crying, deer whistles, whistling intensity and frequency of accident were lower in glutathione-fed group compared to control. During breeding season, use of glutathione as feed supplement could suppress body weight loss and accidents in deer farm.

The purpose of this study was to investigate the snack and beverage intake patterns of students by body mass index groups (BMI 〈18.5, 18.5-23, 23-30, ≥30). Questionnaires were completed by 1381 high school students in Seoul, Incheon, and Gyeonggi-do, the area of Korea's capital region. There were no significant differences in skipping meals for overweight (BMI 23-30 and ≥30) or under-nourished (BMI 〈18.5) students. Girls skipped dinner more frequently than boys. Boys and girls both preferred meat and disliked fish regardless of BMI. Girls with BMI 23-30 disliked vegetables. Boys and girls would rather have crackers, candies, and chocolates than potatoes as snacks regardless of BMI. Obese boys (BMI ≥30) preferred flour-based food, fast food, and other food as snacks. Girls liked fruits more than boys. Snacks were eaten 2-3 times per week, when students were hungry or bored. There were no significant differences in the frequency or reasons (habitual, stressed) for snack consumption by BMI. Girls liked juice more than boys did, and boys preferred soda water more than girls did. Both the under-nourished (BMI 〈18.5) boy and girl groups had more juice than the overweight (BMI 23-30 and ≥30) groups. Obese (BMI ≥30) boys did not more drink soda water than other BMI groups. The under-nourished (BMI 〈18.5) boy group had more soda water than the normal (BMI 18.5-23) and overweight (BMI 23-30) groups. Girls in the overweight (BMI 23-30) group had 2 more cups of soda water a day than the normal group (BMI 18.5-23). Therefore, skipping meals and beverage intake patterns might influence BMI.

This study, 255 people, Gyeonggi-Y Elementary School (Grade 2 to Grade 3) and Power Point educational media activities, made a rice cake, and then through surveys conducted by education, training effect of dietary was analyzed.The name of rice cake(99.1%) and rice cake flour with about 82 percent know.Gratitude to farmers, students have been answered by 91.3% after the dietary change was education. Teaching Satisfaction 'Yes' was answered more than 91.0%. Diet, the importance of education and appreciation for farmers was a positive correlation. Satisfaction with teaching and also showed a positive correlation is very high. Also grateful to farmers and satisfaction with teaching showed a positive correlation with satisfaction. Making rice cake with exercise diet showed that the effect of education is very high. Therefore conducted a systematic practice cooking to suit the students' level of food education will be done efficiently.

This study was performed to analyze the retarded degree of Garaetteok retrogradation added with different ratios 0-15% (w/w) of apple pomace dietary fiber powder (DFP). SEM (×500) showed that air cell size on the Garaetteok surface increased as DFP content increased, whereas control had a compact structure without air cells. The degrees of Garaetteok retrogradation after 3 days at 4 and 25℃ by α-amylase iodine method were 57.44 and 41.55% for control, respectively. On the other hand, those of 15% DFP Garaetteok were 28.38 and 15.05%, respectively. Enthalpy changes (δE) by DSC of control, 10 and 20% DFP Garaetteok after 3 days of storage at 4℃ were 4.41, 4.17, and 3.80 J/g, respectively, whereas those at 25℃ were 2.14, 1.04, and 0.72 J/g. Hardness of 15% DFP Garaetteok was around 48% compared to that of control after 3 days of storage at 25℃. Increasing DFP content from 0 to 15% decreased L color value from 86.2 to 55.1, whereas a and b values increased from -1.9 to 8.9 and from 5.3 to 20.8, respectively. In a sensory intensity test, hardnesses of 15% DEP Garaetteok were significantly different at 1 and 0.1% compared to those of control after production and followed by storage for 3 days at 4℃, respectively.

사과박의 식이섬유를 추출하여 설기떡에 첨가 시 첨가량에 따른 저장 중 품질특성변화를 분석하였다. 설기떡의 색도는 식이섬유첨가량이 증가함에 따라서 L*값은 87.9로부터 65.9로 감소하였으며 a*와 b* 값은 각각 -1.9에서 5.9 및 5.0에서 20.5로 증가하였다. 주사전자현미경(SEM)으로 설기떡의 표면구조를 관찰한 결과 식이섬유를 첨가한 설기떡에는 쌀가루사이에 끼어든 식이섬유가 쌀가루간의 연결을 저해하여 대조구보다 치밀한 구조이지 않았으며 사이사이 공간이 형성되어 있는 것을 볼 수 있었다. 대조구, 10% 및 15%의 식이섬유를 첨가시킨 설기떡의 엔탈피 변화는 3일 후 4oC 저장에서 각각 4.83, 3.80 및 3.18 J/g로 나타났으며 25oC 저장에서는 각각 1.14, 0.60 및 0.60 J/g이었으며 식이섬유첨가는 설기떡의 노화를 지연시키는 작용을 하였다. 대조구와 식이섬유첨가 설기떡 간의 경도를 비교하여 볼 때 실온저장보다는 냉장저장 시 경도증가(노화)억제효과가 컸으며 4oC에서 저장 3 일 후 15%첨가 설기떡의 경도는 대조구의 약 42%수준이었다. 기준 검사물과의 차이검사법에 의한 전체적인 기호도 평가에서 15% 식이섬유를 첨가시킨 설기떡이 제조 직후와 4oC 저장에서 3 일 후 모두 가장 높은 값을 보였으며 대조구와 5% 내에서 유의성 차이를 보였다.

본 연구는 허브 부식토를 이용하여 첨가 수준별 in vitro 반추위 발효특성 평가와 젖소를 이용하여 급여시 유생산성에 미치는 영향을 조사하기 위하여 본 연구를 수행하였다. 시험 1에서는 티머시 건초를 기질로 하여 허브부식토(herbaceous peat)를 0,1 및 5%를 3반복으로 각각 첨가하여 in vitro 반추위내 pH, 가스발생량, VFA (volatile fatty acid), ammonia-N 및 건물분해율을 조사하여 반추위내 발효성상의

The author previously reported that the addition of inuloprebiotics to broiler diets produces growth performance that is superior to antibiotic supplementation. The present study furthered this work by evaluating the quality with thiobarbituric acid reactive substances (TBARS) of the meat from chickens fed inuloprebiotics produced using Korean Jerusalem artichoke. Male Ross 308 broilers (n=240) were randomly allotted to a 35 day regimen of dietary control (no supplementation), dietary antibiotics supplementation (8 mg avilamycin/kg diet), or dietary inuloprebiotic supplementation (450 mg inuloprebiotics/kg diet). The pH, water holding capacity, L*value (lightness), and b*value (yellowness) of the chicken meat weres ignificantly higher in the inuloprebiotic group. The TBARS value of chicken meat stored at low temperature tended to increase according to the length of storage, and was significantly lower in the inuloprebiotics group. The sensory scores of the cooked chicken meat were significantly higher in the inuloprebiotics group. The results indicate that the addition of inuloprebiotics as anantimicrobial agent to broiler diets can greatly improve the quality and self-life with reducing TBARS of chicken meat.

We investigated the effect of glutathione supplementation on body weight gain, feed intake, velvet antler yield and economic analysis in elk bulls. A total 14, 2-year old male elks were divided into 2 groups with control or glutathione treatment. Elks were fed concentrate feed at the level of 1.5% relative to body weight (3.1 kg). and allowed to consumed hay as roughage ad libitum. Glutathione was supplemented at the level of 6 mg/kg. Average daily gains (ADG) for 2-years old elks were 234.1± 7 and 247.6±22 kg in control and glutathione fed groups, respectively. Treated group had higher ADG than control (p<0.05). Individual daily DM intakes were 5.34±0.70 and 5.64±0.71 kg in control and glutathione supplemented groups, respectively. Glutathione-fed group showed an additional intake of 298 g on an average. Production of velvet antlers for elk yearlings was 4,229±720 g and 4,653±960 g in control and glutathione supplemented groups respectively. Analysis of economics efficiency revealed 8% higher revenue index in glutathione supplemented groups. In conclusion, glutathione supplementation showed increase of DM intake and ADG in elk bulls, and could also increase velvet antler production.

A method based on high-performance liquid chromatography (HPLC) with ultraviolet detection has been developed to quantify coenzyme Q10 (CoQ10) in raw materials and dietary supplements. Single-laboratory validation has been performed on the method to determine linearity, selectivity, accuracy, limits of quantification (LOQ) and repeatability for CoQ10. An excellent linearity (r = 0.999) was observed for CoQ10 in the concentration range 15.625~500 μg/mL in dietary supplement. Observed recovery of CoQ10 was found to be between 98.33 and 99.38%. LOQ was found to be 250 μg/mL Repeatability precision for CoQ10 was between 0.15 and 0.21% relative standard deviation (RSD). Further, limited studies showed that some adulterants and degraded material could be satisfactorily separated from CoQ10 and identified.

세계 콩 교역은 일부 소수 수출국과 다국적 곡물메이저가 주도하는 시장구조이며, non-GM 콩 교역물량은 매년 축소된다는 특징을 가지고 있어 우리나라와 같이 국민이 필요로 하는 콩을 해외시장에서 대부분 조달하는 수입국에게는 매우 불리한 여건이다. 2009년 현재 우리나라의 해외 non-GM 식용 콩 조달은 중국(76%)과 미국(22%)에 집중되어 있으며 특히 중국으로부터의 수입 비중이 매우 크다. 하지만 중국은 근본적으로 대규모콩 순수입국이며, 최근 국제 곡물가격이 상승하자 중국은 국내 물가 안정 차원에서 주요 곡물 수출에 대해 수출세를 부과하고 수출에 대한 관세 환급제를 폐지하는 등 보호적 태도를보이고 있다. 이는 우리나라와 같은 식량수입국에게 안정적인미래 식량 자원 확보의 필요성을 환기시켰다. 이에 단기적으로 무엇보다 콩 수입선 다변화, 선물거래의 활용, 해외농업개발과 연계된 조달방안 마련 등 해외 조달방식의 다양화가 필요하다. 세계적으로 GM 작물의 재배면적이 늘어나는 추세임에도 국내 소비자들의 non-GM 작물에 대한 수요는 계속 증가할 것으로 보인다. 향후 non-GM 콩의 수요가 늘어날 것에 대비하여 기존 미국과 중국에서 대부분의 콩을 수입해 온 것에서 벗어나 곡물메이저가 진출하지 않고 근거리에 위치한 중앙아시아나 연해주, 또한 수확시기가 다른 점을 이용할 수 있는 남반구 국가들과 같이 다양한 지역의 여러 가지 요소를 전략적으로 고려한 공급기반 확보 노력이 필요하다. 또한 일본과 같이 고품질의 non-GM 콩을 안정적으로 확보하기 위해서는 국제곡물 유통기업을 설립하여 효과적 수입조달 체계를 구축하는 것도 필요하다. 동시에 국내적으로는 콩비축 관리제도를 확대 운영하고 조기 경보시스템을 구축하는제도적 노력과 함께 국내 생산 증대를 위한 다각적인 정책노력도 기울여 나가야 할 것이다.
