  • Sweet dough bread is made by using sponge & dough method with the sweet dough formula which consists of wheat gluten and baking powder. The effect of wheat gluten and baking powder to the bread has been studied after the dough frozen, stored, thawed, fermented. and baked. The bread quality has been evaluated by measuring the product volute and also by the sensory evaluation after baking. When 4% of wheat gluten and 4% of baking powder were added into the dough. the bread has a larger volume than that of 2% wheat gluten and 2% baking powder in volume. However. wheat gluten shows better result than baking powder in terms of volume. In sensory evaluation, the bread has higher score when 2% of wheat gluten and 2% of baking powder were added into the dough than that of 4% wheat gluten and 4% baking powder. Consequently, breads show better result when 2% wheat gluten and 2% baking powder were added into the dough than that of 4% wheat gluten and 4% baking powder.

  • 최근 초등학생들은 간식은 물론 끼니를 위해서 스스로 식품이나 음식을 선택하고 구매하는 식생활 관리의 주체자가 되고 있다. 본 연구는 초등학생의 간식구매실태와 이에 영향을 미치는 식생태적 요인을 파악하고자, 서울과 충청남도의 대도시, 소도시 및 농촌의 4개 지역의 초등학생 4, 5, 6학년 총 431명(남 223, 여 208)과 그 학부모를 대상으로 간식섭취, PC와 TV 이용도, 학부모의 영양지식과 식태도, 간식구매빈도 등을 설문지 조사를 하였다. 조사대상 초등학생의 평균 신장과 체중은 교육부의 학생 신체검사 결과보다 약간 높거나 비슷하였으나, 조사대상의 30.6%가 저체중이고 10.8%가 비만이었다. 가정의 월 소득은 101-200만원이 가장 많았고(56.3%), 아버지는 대졸 이상이 59.7%, 어머니는 고졸 이상이 55.9%로 가장 많았으며, 어머니는 44.1%가 직업을 갖고 있었다. 학생의 월 용돈은 2,001-5,000원이 31.0%로 가장 많았으며 간식 비는 1일에 500원 미만이 46.0%로 가장 많았다. 간식섭취 빈도는 1일에 1번 섭취가 51.5%로 가장 많았고 간식 구매 시 고려사항은 맛, 가격, 영양가와 유통기한의 순 이었다. 조사대상의 46.9%가 PC통신 또는 인터넷을 사용하였고 사용시간은 1시간 미만이 53.8%로 가장 많았으며, 하루 평균 TV 시청시간은 2~4시간미만이 46.4%로 가장 많았다. 학부모의 평균 영양지식 점수는 13개 문항 중 8.16 $\pm$ 2.16으로서 평균 62.8%의 정답 율을 보였으며, 식 태도 점수는 총 50점 만점에 전체 평균이 43.22$\pm$4.04로서 비교적 양호하였다. 식품별 구매빈도를 보면 1주에 1회 이상으로 나타난 것은 우유, 과자류, 빙과류, 라면, 주스 및 껌의 순 이었고, 햄버거, 피자, 호떡은 한 달에 1회 또는 그 이하로서 가장 낮았다. 과자, 라면, 빙과류의 구매빈도는 가정수입과 아버지와 어머니의 교육수준과 음의 상관 관계를, 학생의 월 용돈, TV 시청시간 및 간식섭취 빈도가 높을수록 와는 양의 상관관계를 보였다. 라면과 탄산음료는 부모의 영양지식이나 식 태도와 음의 상관관계를 나타냈고, 햄버거 구매빈도는 가정수입과 아버지와 어머니의 교육수준이 높을수록 잦았다. 학생의 간식빈도가 높을수록 우유섭취빈도는 낮았으며, 과자, 빙과, 사탕, 닭 꼬치, 감자튀김, 돈까스, 튀김의 구매빈도가 증가하여 간식내용이 영양적으로 양호하지 않음을 알 수 있다. 또한 TV 시청시간이 길수록 간식빈도와 유사한 구매 양상을 나타냈다. PC이용시간이 길수록 과자와 빵의 구매빈도가 낮아지고 껌의 구매빈도가 높아져 흥미롭다. 결론적으로 조사대상 초등학생은 간식 구매시 영양가보다는 맛을 중요시하며, 우유를 제외하면 주로 탄수화물과 당류식품의 구매빈도가 높다. 또한 가정 소득, 부모 교육수준과 영양지식, TV시청시간, 학생의 간식 비와 간식빈도 등 환경요인들이 식품구매에 영향을 주었다. 따라서 영양사를 중심으로 간식 선택의 중요성과 식품 구매 원칙에 대한 체계적인 영양교육을 학생과 아울러 학부모에게도 실시하여 초등학생의 바른 간식 구매능력을 향상시켜야 할 것이다.

  • Microbial contamination levels and legal preservative appropriation in child foods sampled from the neighborhood of elementary schools were investigated. Contamination levels of total aerobic bacteria in seasoned dried fish slices, bread and snacks, sausages, sugar products and dumplings were $1.70\~6.91,\;1.40\~6.66$, 4.50, $3.48\~5.88$, and $4.79\~4.82\;log_{10}$ CFU/g, respectively. Coliforms in four kinds of foods except for dumplings were $2.30\~6.60,\;4.22\~~5.98$, 2.00, and $2.78\;log_{10}$ CFU/g, respectively. Yeasts and molds in those foods were $0.10\~4.23,\;1.66\~4.91,\;1.46\~1.91,\;1.56\~4.26$, and $1.12\~1.84\;log_{10}$ CFU/g, respectively. S. aureus was isolated in $18\%$ of seasoned dried fish slices ($1.00\~2.84\;log_{10}$ CFU/g), $33\%$ of bread and snacks ($1.70\~1.79\;log_{10}$ CFU/g), $50\%$ of sausages ($3.28\;log_{10}$ CFU/g), $22\%$ of sugar products ($2.16\~2.88\;log_{10}$ CFU/g), and $100\%$ of dumplings $(1.18\~3.31\;log_{10}\;CFU/g)$ B. cereus was isolated in $21\%$ of seasoned dried fish slices $(0.70\~2.48\;log_{10}\;CFU/g)$, $50\%$ of bread and snacks $(0.70\;log_{10}\;CFU/g)$, and $11\%$ of sugar products $(0.30\;log_{10}\;CFU/g)$. Both E. coli and Salmonella spp. were not isolated in all samples. Preservative was only labeled on four products among 15 products but preservative on 13 products including 4 products haying an indication of preservative were not detected. Moreover, $0.30\%$ of sorbic acid was detected in one of Squid products . The results of this study indicated that the hygienic level of child foods in Gyeonggi and Incheon was very poor and need to be improved.

  • This study evaluated daily intakes of BHT, BHA, and TBHQ in Korean. The daily intakes were estimated using both a dietary survey approach and food supply survey approach. In the dietary survey approach, individual dietary intake data from the Korea National Health and Nutrition Survey in 2005, as well as analytical results of BHT in 131 samples, BHA in 134 samples, and TBHQ in 104 samples, were used to assess daily intakes of the antioxidants. In the food supply survey approach, both total production amounts of BHT, BHA and TBHQ and maximum permitted levels of the antioxidants were used to calculate daily intakes. In the dietary survey results, the average daily intakes of BHT, BHA and TBHQ were 0.8, 0.5, and 0.3 ${\mu}g$/kg body weight/day, respectively, and below 0.2% of the ADI (acceptable daily intake) set by JECFA (Joint FAO/WHO Expert committee on Food Additives). In the food supply survey approach, the average daily intakes of BHT, BHA,and TBHQ were all 0.3 mg/kg body weight/day. The ratios of ADI were 97, 60, and 40%, respectively. According to these results, daily intakes of BHT, BHA, and TBHQ in Korean are lower than the ADI.

  • Purpose: To provide the primary data on dietary guidelines for the management of obesity, we analyzed the intake rate of food groups and dish groups according to obesity and age. Data were obtained from the Korea National Health and Nutrition Examination Survey (KNHANSE, 2013-2018). Methods: This study analyzed the data of 21,184 adults aged 19-64 years, obtained from the KNHANSE 2013-2018. The 24-hour recall was performed and the food groups were classified into six representative food groups (grains, meat·fish·eggs·legumes, vegetables, fruits, milk and dairy, and oil and sugar), and 'alcohol' and 'others'. The dish groups were classified into a total of twenty-four types. Results: The normal group included 9,004 subjects (42.5%), while the obese group had 12,180 subjects (57.5%). The food groups showing significant differences according to obesity were grains (p < 0.001), meat/fish/egg/legumes (p < 0.001), and vegetables (p < 0.001); similar results were obtained in both male and female. Comparing the intake rate of food groups and dish groups targeting only the obese group according to age, the food groups showing significance between the obese group and the normal group were grains (p < 0.001) and vegetables (p < 0.001), with significantly increased intake in both genders. Considering the dish groups, significant increases were determined for stews (p < 0.001), seasoned vegetables (p < 0.001), and kimchi (p < 0.001) in male, and for rice (p < 0.001), seasoned vegetables (p < 0.001), kimchi (p < 0.001), and rice cakes (p < 0.001) in female. Conclusion: The results of this study determined that the intake ratio of food and dish groups differs by age in obese adults. We believe that our results can be used as primary data for forming dietary guidelines for obese adults in the future.

  • Zearalenone (ZEA) is an estrogenic mycotoxin mainly produced by Fusarium graminerum, a species which colonizes a wide variety of cereals, including wheat, barley and processed products. A survey of ZEA contamination was conducted on 141 dried confectioneries, 59 breads and rice cakes, 135 noodles and 101 other products, for a total of 432 commercial samples. Samples were analyzed by high performance liquid chromatography with fluorescence detection (HPLC-FLD) after immunoaffinity clean-up and was confirmed by liquid chromatography tandem mass spectrometry (LCMS/MS). The limits of detection and quantification were 2.0 and $6.0{\mu}g/kg$, respectively. The recovery ranged from 80.2% to 98.4% in the cereal based product. ZEA was detected in 38 samples (8.8% incidence), including 3 snack, 2 biscuit and 33 other cereal products. The ZEA contamination levels were in the range of $5.38-53.76{\mu}g/kg$. Finally, LC-MS/MS analysis of the contaminated samples was conducted to confirm the detected ZEA, and all 38 samples showing ZEA by HPLC-FLD were confirmed by LC-MS/MS.

  • Purpose: The purpose of this study was to assess the diet intake status and quality of adults from North Korea who had lived in Seoul and Gyeonggi-do, using the nutrition quotient (NQ) for Korean adults. Methods: A number of 166 adults aged from 20 to 64 years were enrolled as study subjects. A structured questionnaire was used to collect information on their demographic characteristics, food consumption frequency, eating behaviors, and NQ. The NQ score was then used to measure the overall diet quality. The NQ score was composed of four major age-based categories. 'Balance', 'Diversity', 'Moderation', and 'Dietary behavior' were utilized as scores for measurements within each of the four categories. The scores for all four categories were summed up, resulting in the total NQ score. Participants' age groups were stratified by 20's, 30's, 40', and over 50's. A χ2 test and generalized linear regression (GLM) model were used to assess a significance for difference of subject distribution in categorical and continuous variables in the food consumption frequency, eating behaviors, and NQ scores. Results: Participants in younger age groups were more likely to report consumption of ramyeon, fast food, sweet and greasy baked products, processed beverage, delivery food, and night snacks than the older age groups. Most importantly, participants in 20's age group were less likely to report the total NQ and moderation score than the 50's age group. Conclusion: In this study, the 20's age group displayed a lower NQ characteristic for an unbalanced diet. Therefore, it is imperative for adults from North Korea to be given individualized diet instructions along with nutritional education programs.
