  • 최근 새로운 바다 자원으로서 “해양 심층수”가 주목받고 있다. 해양 심층수(深層水, deep sea water)는 태양광이 도달하지 않는 수심 200 m 이상 깊이의 물로 수온이 2$^{\circ}C$ 이하로 연중 거의 변화가 없는 저온안정성과 무기 영양염을 다량 포함하는 특징이 있어 심층수의 활용도는 매우 높다. NaCl만 제거하면 훌릉한 생수가 되기 때문에 심층수를 원료로 한 식품, 화장품, 의약품 개발에 대한 관심이 높아지고 있다. 미국, 일본 등지에서는 10여년전부터 심층수를 이용한 에너지, 수자원, 생수 및 식품 산업이 활발히 진행되어졌다. 현재 식품 산업분야로는 두부제조, 빵, 청주, 간장, 된장 등의 발효식품에 대한 연구가 진행되어지고 있다. 심층수를 적당하게 첨가하면 알코올 농도가 높아지는 발효강화작용이 있다. 새로운 건강 먹거리를 갈망하는 현대인들에게 해양 심층수를 이용한 발효식품은 매우 환영받을 것으로 사료된다. 이에 본 연구는 해양 심층수의 다양한 자원성을 효율적으로 활용하기 위해 심층수의 청정성과 풍부한 미네랄을 함유한 심층수의 농도에 따른 효모의 증식도를 알아봄으로서 적응력 강한 효모를 조사하였다. 실험에 사용한 해양 심층수는 淸凉飮料水(日本ナチュラルヘルス株式會社, 深透水 1550) 사용하였다. 효모균주는 경북과학대 전통식품 연구소에서 보유하고 있는 9종의 효모를 사용하였으며, 심층수 경도 250, 500, 1000의 심층수와 1차 증류수(대조군)에 sucrose 10% 첨가한 당용액을 사용하였다. 또한 당의 적응력을 알아보기 위해 sucrose 10, 15, 20% 첨가 당용액을 사용하여 Sacch.cerevisiae kluyvery DJ97 효모의 증식도를 알아보았다. 그 결과, Saccharomyces cerevisiae 12호 균주가 심층수 경도 500인 시험군에서 증식력이 높았으며, Saccharomyces cerevisiae 901 균주는 경도 1000인 시험군이 대조군에 비해 증식력이 높게 나타나 효모균주의 종류와 심층수의 첨가량에 따라 적응력이 차이가 있었다. 당농도와 심층수 첨가량에 따른 효모 균주의 발효력을 알아본 결과 심층수 경도 200의 당 10% 첨가군에서 가장 잘 증식하는 것으로 나타나, 알코을 효모균주의 발효력을 높이는데는 최적의 농도가 있음을 알 수 있었다. 따라서 심층수를 이용한 다양한 발효식품에 대한 연구가 요구되어진다.

  • 문명이 고도로 발달하고 환경위생상태가 양호한 최근에도 세계 도처에서 끊임없이 식중독이 발생되고 있다. 세계보전기구에 의하면 현재 전세계적으로 가장 많이 발생하는 인간의 건강상의 위해 요인은 식중독을 포함하여 오염된 식품으로 인한 질병이라고 생각되고 있다. 이들 중 일부는 출처에서부터 오염된 식품에 의한 것이며, 그 나머지는 식품을 부주의하게 취급함에 의한 것이다. 실제로 지구상 인구의 일부는 생존을 위해서 먹는 음식물에 의하여 식중독이 야기되어 불필요하게 사망하고 있는 것이다. 우리의 일상의 식생활에 있어서 음식물의 취급과 섭취에 주의를 기울이고 올바른 위생 행태를 실천한다면 식중독 발생과 사망, 그리고 경제적 손실을 상당히 줄일 수 있을 것이다. 한편 식중독으로 보고되는 공식적인 추계는 선진국에서조차도 빙산의 일각에 불과하다는 것이 세계적 전문가들의 지론으로서 대개 실제 발생사례의 10% 정도만이 보고되는 것으로 알려지고 있다. 우리 나라의 경우 보고된 통계자료에 의하면 1965년부터 1986년까지의 식중독 경향은 사망자수는 상당히 감소 (연간 40여명에서 10여명 수준으로) 하였으나 이는 아직 급성전염병으로 인한 사망자수를 상회하는 수준이었다. 최근 10년간 (1987-1996)에는 발생수가 연간 31-104건으로 집계되고 있으며 사망자수는 아직도 연간 5-12명으로 나타나고 있다 (감염병 발생정보 등). 1977년에 발생하였던 학교급식 식중독 사례 (1977년 9월, 초등학교 점심급식, 발병자 5,500명 이상, 사망자 1명, 원인식품=크림빵, 병인물질-포도상구균)는 아직도 커다란 교훈으로 남아있다. 우리 나라의 경우 이와 같이 공식적인 식중독 통계자료의 결과가 제시되고는 있으나 식중독 사례에 대한 면밀한 사안이 밝혀지는 경우가 많지 않다. 또한 그 발생 경위나 원인요소에 대해서는 일반에게 공개되지 않고 있어, 우리가 실천하여 식중독을 예방할 수 있는 정보가 함께 제시되지 못하는 형편이다. 따라서 본 고에서는 최근 수년간 외국에서 학교급식을 비롯한 집단급식 등에서 발생한 식중독 사례를 중심으로 고찰, 분석하였다. 이로부터 식중독 발생에 기여한 주요 원인을 찾아내고 여기서 얻어지는 교훈을 토대로 식중독 발생을 예방 및 최소화할 수 있는 실천적 대처 방안을 모색해 보고자 한다.

  • This study was carried out to investigate the self-reported health and eating habit of the elite female adolescent athletes in Incheon. The subjects were 102 elite female athletes of middle and high schools located in Inchon. A self-administered Questionnaire was used for this cross-sectional survey. Statistical analysis by two-way ANOVA was performed to discriminate between the main effects of age (as middle and high school athletes) and sports type, and their interaction. As use of nutritional supplements, 35.8% of the total subjects took vitamin and iron supplements and 62.5% of field and track athletes took vitamin and iron supplements. While mental stress related to exercise was much in fencing &gt; shooting &gt; field and track &gt; swimming athletes, physical burden during training was higher in swimming &gt; field and track &gt; fencing &gt; shooting athletes. More than half of the subjects showed irregular menstrual cycle. As the most severe problem of eating habit, they reported skipping meal &gt; overeating &gt; prejudiced meal &gt; preference to salty and spicy foods. More than half of the subjects skipped meal over three times per week. Fencing and shooting athletes showed very significantly higher frequency of skipping meal and more irregular breakfast time compared to those of other sport types. As for snack, they ate cookies, carbonated drink, chocolate, candy &gt; milk, yogurt, ice cream &gt; cake, bread, rice cake &gt; fried noodle &gt; hamburger, pizza. Therefore, nutritional counseling and education by sport type are necessary for health and good eating habit of these elite female adolescent athletes.

  • The purpose of this study was to evaluate night time eating habits, dietary habits, and nutrient intake in university students according to residence type. A survey was conducted by administering questionnaires to 664 students. Questionnaire interview and 24-h dietary recall were conducted. Subjects were divided into three groups according to residence type: dormitory boarding (DB group, N=313), self-boarding (SB group, N=246), and living with parents (LWP group, N=105). Average ages in the DB, SB, and LWP groups were 21.3, 22.2, and 22.1 years, respectively. There were no significant differences in body mass index between the three groups. In total, 77.3% of students regularly ate night time snacks. The proportion of students who reported night time eating was 84.0% in the DB group, 73.6% in the SB group, and 65.7% in the LWP group (P<0.001). In terms of food types consumed during night time eating, the DB group showed a significantly higher rate of consumption of fried chicken and flour-based foods than the SB and LWP groups, whereas the SB group showed a significantly higher rate of consumption of alcohol beverages than the DB and LWP groups. Energy, carbohydrates, protein, fat, vitamins, and mineral intakes were significantly higher in the DB group than in the SB and LWP groups. In addition, intake of cholesterol per 1,000 kcal was significantly higher in the DB group than in the SB and LWP groups. Thus, SB and DB students seemed to have more night time eating problems than LWP students. Accordingly, nutritional education is needed to support the development of healthier eating habits, in particular, night time eating habits, among students living in dormitories and in self-boarding situations.

  • The purpose of this study was to investigate the sweets preference, food frequency, dietary habits, and nutrition knowledge of middle school students who like sweets. A survey instrument consisted of a self-administered questionnaire, a food frequency questionnaire, and anthropometric measurements. Three hundreds thirty five students aged 13 to 15 years old were divided into two groups, Sweets Liking Group (SLG) and a control group based on the subjects' scores for dietary habits, sweets preference, and food frequency. For dietary habits, the score for meal regularity was significantly lower in the SLG group compared to the control (p<0.001). In addition, the SLG group was more likely to skip breakfast (p<0.001), eat inadequate amount of meals (p<0.001), and consume yellow-green vegetables less frequently (p<0.001) than the control. The subjects' nutrition knowledge was assessed using 20 questions representing five categories, including functions of nutrients, nutrition and health, food pyramid and food groups, healthful snacking and the right dietary attitude. The total scores for nutrition knowledge indicated that the SLG had a poorer nutrition knowledge for all five categories than the control (boys p<0.05, girls p<0.01). For food frequency, the SLG consumed more sweets but less grains, cereals, fishes, beans, vegetables, and milk and milk products than the control (p<0.001). Strong positive correlations appeared between sweets preference, sweets frequency, and sweets-related dietary habits; and all were negatively correlated to nutrition knowledge. Sweets frequency was negatively related to meal regularity, breakfast consumption, meal adequacy, and balanced meals. The findings suggest that nutrition education is necessary to improve the dietary pattern, especially sweets consumption, of Korean young adolescents.

  • This study described the status of snack intake and personality of middle school students, determined the differences in snack intake and personality according to gender and grade levels, and examined the effect of snack intake on personality. Data were collected from a self-reported survey from students of a middle school in Gwangju city and 717 questionnaires used for the analyses. The data were analyzed for frequency, percentage, mean, standard deviation, Cronbach's α, t-test, ANOVA, Duncan test, and multiple regression analysis using SPSS/PC 18.0 program. The results obtained were as follows. First, as for the snack intake frequency, '1~2 times per a day' had the largest number of responses(42.3%), followed by 'sometimes'(37.6%), '2~3 times per a day'(12.6%), 'never'(7.5%). As for the reason of snack intake, 'habitually'(27.3%) had the largest number of responses, followed by 'insufficient amount of meal'(21.0%), 'skipping meals'(13.6%), and 'stress relief'(8.2%). Mean score of agreeableness was the highest(3.64) among the personality components followed by Openness/intellect(3.42), Extraversion(3.36), Conscientiousness(3.15), and Emotional Stability(3.09) on the 5-point scale. Second, there were statistically significant differences in Emotional Stability depending on the gender. There were statistically significant differences in Extraversion, Agreeableness, and Openness/intellect by the grade level. Third, fruit intake frequency had statistically significant influence on Extraversion(β=.134). Intake frequency of bread(β=-.099), fruit(β=.142), ice cream(β=.092), and rice cake(β=.090) had statistically significant influence on Agreeableness. Intake frequency of bread(β=.105), drink(β=-.113), fruit(β=.113), and flour-based food(β=-.126) had statistically significant influence on Emotional Stability. Intake frequency of fruit(β=.106) and milk(β=.110) had statistically significant influence on Openness/intellect. Intake frequency of fruit had statistically positive influence on all the personality components. Intake frequency of rice cake had statistically positive influence on two personality components. Intake frequency of drinks had statistically negative influence on Emotional Stability. The outcomes indicate that snack intake affects the personality of adolescents.
