The purpose of this study was to investigate the comparison of nutrient intake and metabolic syndrome between single person households and non-single person households in elderly subjects. We analyzed data from 2,903 subjects ≥ age 65 who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2013~2015. As a result, single-person households had lower income and economic ability, overall nutrient intake was deteriorated, and the proportion of high-carbohydrate intake was high, compared to non-single person households. After adjusting for potential confounders (sex, age, education, household income, economic activity, smoking status, alcohol consumption, walking frequency, health status, depression status, and dietary factors), the single-person household showed a tendency of 1.22-fold higher ORs of metabolic syndrome and 1.3-fold higher ORs of hypertriglyceridemia than the non-single-person household. We suggest that the single-person household may be associated with increased prevalence of metabolic syndrome and hypertriglyceridemia in the elderly subjects.

본 연구에서는 국내산 포도 품종을 이용한 ‘unfined’ 혹은 ‘unfiltered’ 포도주의 제조 가능성을 알아보고자 하였다. 경북 영천에서 재배된 Muscat Bailey A 품종을 이용하여 제조하였으며 가당을 하여 28°Brix로 조절하였다. 알코올 발효 후 정제 과정에 들어가기에 앞서 청징제 첨가와 여과기 사용 여부에 따라 시료 A, B, C로 나누어 청징, 여과, 병숙성 후의 각 시료별 이화학적 성분을 측정하여 비교 분석하였다. 시료 A는 청징제를 첨가하고 여과기도 사용하였고 시료 B는 청징제만 첨가하고 여과기는 사용하지 않았으며, 시료 C는 청징제도 여과기도 사용하지 않았다. 병 숙성을 마친 후의 각 시료별 총 페놀 함량, intensity, hue, color, 유기산 함량, 휘발성 향기 성분을 측정하여 비교 분석하였다. 총 페놀 함량은 시료 C가 다른 시료들에 비교해 최대 19% 정도 높은 수치를 나타내었고, intensity와 hue, color의 측정 결과는 예상대로 여과 과정을 거친 시료 A가 다른 시료들과 비교하여 가장 선명하고 투명한 색상을 나타냈으나 색의 안정성 면에서는 떨어졌다. 유기산 함량과 휘발성 향기 성분의 측정은 전체적인 결과에서 각 시료별로 차이가 크게 나타나지 않았다. 이는 청징 과정과 여과 과정의 유무에 따른 차이라고 하기보다 다른 요인들에 의해 영향을 받게 된다고 사료된다. 실험 결과 중에서 시료별 큰 차이를 나타내지 않았던 유기산 함량은 발효 중 malo-lactic fermentation 과정이 이루어졌더라면 더욱 좋은 결과를 얻을 수 있었을 것이라 생각되며, 휘발성 향기 성분은 청징 과정이나 여과 과정이 아닌 다른 양조 과정에서의 조건의 변화가 필요할 것으로 보인다. Since the domestic grape wine industry has been stagnant, the quality of Korean wine must be improved to compete with imported wines. For improving the quality of domestic wine up to ‘unfined’ or ‘unfiltered’ wine, this study investigated the possibility of producing ‘unfined’ or ‘unfiltered’ wine and their physicochemical characteristics. Muscat Bailey A as a domestic grape was selected to make wine. Prior to refining process after alcohol fermentation, the wine samples were divided into three specimens depending on the treatment of bentonite for clarification and filter (sample A treated with both bentonite and filter, sample B treated with bentonite only, and sample C treated without bentonite and filter). The physicochemical characteristics of each specimen after one week matureness were then investigated. Sample C showed highest values in total phenol and organic acid content among others. Samples B and C showed more stability in intensity, hue, and color. Although it is hard to compare domestic wine with imported wine, it may be possible to improve the quality of domestic wine and contribute to the development of the domestic wine industry when further studies are conducted on in-depth fermentation of wine and improvement of microbiological stability.

This study compared the lifestyle patterns, dietary patterns, and health care practices of Korean middle-aged people by household type, and ultimately analyzed their relationship with different risk factors for the prevalence and severity of metabolic syndrome. We analyzed the data from 4,755 subjects who were from 40 to 64 years old, and gathered our sample from participants of the Korea National Health and Nutrition Examination Survey from 2013 to 2015. Our results showed that single-person households had lower economic income levels, lower subjective health statuses, and higher levels of food instability than households with two or more individuals. The incidence of metabolic syndrome was 1.64 times higher in single-person households than in households with two or more individuals. After adjusting for potential confounding factors (sex, age, education, household income, smoking status, health status, and dietary factors), single-person households showed 1.75 times higher hypertriglyceridemia ORs than non-single-person households. In the conclusion of our study, we suggest that middle-aged people in single-person households may be at greater risk for metabolic syndrome and hypertriglyceridemia.

건조된 감국 열수추출물의 첨가 방법에 따른 국화주의 특성 연구

방병호(Byung-Ho Bang),백진경(Jean Kyung Paik),최재영(Jea Young Choi),정은자(Eun-Ja Jeong),이문수(Moon-Soo Rhee),이동희(Dong-Heui Yi) 한국식품영양과학회 2015 한국식품영양과학회지 Vol.44 No.9

본 연구에서는 요록에 기록되어 있는 양조법으로 감국 열수추출물 첨가량을 달리하여 국화주를 제조하고 그에 따른 품질 특성의 연구를 목적으로 pH, 알코올 농도, 산도, 환원당함량, 총 페놀 함량과 DPPH radical 소거 활성 능력을 측정하였으며, 유리당, 유기산 함량 분석, 색도 측정을 통한 이화학적 실험을 하였다. pH 측정 실험에서는 감국 열수추출물이 투입되지 않은 control을 제외한 각각의 시료가 pH 5.0 이상에서 발효가 시작되어 2일이 경과한 때에 급격하게 pH 3.5까지 낮아졌다. 이후 pH 3.5에서 pH 3.9 사이에서 큰 변화 없이 발효가 끝날 때까지 유지하였다. 산도는 lactic acid(%)로 나타내었으며 pH 수치와는 반대로 1일이 경과하였을 때 급격히 상승하였다. 이후 pH 수치와 마찬가지로 급격한 변화를 보이다가 4일이 경과하면서 반응이 완만해졌다. pH와 산도 측정에서는 감국 열수추출물을 투입하지 않은 시료와 투입한 시료와의 차이가 크지 않았다. 알코올 농도의 변화에서는 4일이 경과할 때까지 급격히 상승하였으나 이후로는 완만하게 상승하여 6일 이후로는 그 상태를 유지하였다. 이는 환원당의 함량 변화와 반비례하며 4일이 경과한 후로는 반응이 완만해졌다. 알코올 농도와 환원당 함량의 변화 역시 pH와 산도에서의 변화처럼 큰 차이를 보이지 않았다. 총 페놀 함량은 gallic acid(mg/L)로 나타내었으며 감국 열수추출물의 첨가량이 일정량 이상일 경우에만 감국 열수추출물 비첨가군보다 총 페놀 함량이 높게 측정되었다. 실험으로 감국 열수추출물의 첨가로 양조한 국화주의 항산화 효과를 증대시키려면 5% 이상을 넣어야 효과를 볼 수 있는 것으로 나타났다. 유리당은 모든 시료에서는 arabinose가 가장 많이 함유되어 있는 것으로 나타났으며, glucose와 maltose, xylose는 소량으로 함유되어 있고 mannose는 5%, 10% 감국 열수추출물을 첨가한 국화주만 함유되어 있었다. 유기산 측정 시 감국 열수추출물 양에 비례해서 대체로 증가로 나타났다. 본 실험의 결과를 토대로 감국의 기능성 측면의 심도 있는 연구가 필요할 거라 생각되며 이는 감국을 이용한 식품개발에 있어서도 좋은 기초자료가 될 것이라 생각한다. This study investigated the effects of addition of Chrysanthemum indicum L. extracts on quality characteristics of Kukhwju during fermentation. Fermented liquors without C. indicum L. were used as the control group. For experimental groups, we added 1, 2, 5, and 10% C. indicum L. extracts and brewed according to the addition method written in Yorok. The pH level during fermentation phase, alcohol concentration, level of reducing sugars, and acidity were measured in each of the experimental groups. After fermentation, we measured total contents of phenols, antioxidant effects, free sugars, organic acids, and chromaticity. During fermentation, no significant difference was observed between the C. indicum L. group and control group. Regarding total phenol contents and antioxidant effects, only the 5% and 10% C. indicum L. groups showed higher contents of phenols than the non-addition group. In general, 5% and 10% C. indicum L. addition groups were positively evaluated. In conclusion, Kukhwaju with 10% C. indicum L. extract showed the best antioxidant effects. In the present study, we obtained different characteristics and determined the optimum addition amount of C. indicum L.

In this study, data from the 7th (2016~2018) and 8th (2019) Korea National Health and Nutrition Examination Surveys were used, which included 5,325 subjects. Health behavior, dietary and nutrient intake status, physical measurement and biochemical characteristics, and risk factors for elderly related chronic diseases were classified and analyzed according to the changing composition of single households and other households in the current society. As a result, the ratio of current smokers and drinkers in young adult single households, walking less than 30 minutes per day, subjective health status was poor, breakfast rate less than three times per week, eating out frequency more than once a day, lipid intake ratio to total calories, saturation fatty acid intake were significantly higher. In addition, waist circumference, and diastolic blood pressure were significantly higher. However, dietary fiber intake level was significantly lower. The results for hypertension, which is the representative chronic disease that causes old age-related chronic diseases, were significantly higher in single households (ORs=1.400 (95% CI: 1.095, 1.791), p=0.007). Although young adults may not have showed particularly serious health problems yet, education is believed as important to recognize and prevent age-related disease risk factors.

Red Chinese cabbage is rich in anthocyanins, with beneficial effects on anti-obesity and lipid profiles. The purpose of this study was to examine the anti-obesity effects of red Chinese cabbage. Four-weeks old Spague-Dawley male rats were divided into four groups for six weeks as follow: Normal Diet (ND), High Fat Diet (HFD), HFD + Red Chinese Cabbage Diet (RCD), HFD + Red Chinese Cabbage Juice (RCJD). After six weeks, the liver weight was significantly higher in the HFD group than in the other groups, and the RCD and RCJD groups showed similar values to the ND group. The epididymal fats were significantly higher in all high fat diets (HFD, RCD, RCJD) than in the ND group and there was statistical significance in the post-tests when comparing the RCD and RCJD groups with the HFD group. Triglycerides significantly decreased in the RCD group. In conclusion, red Chinese cabbage is rich in anthocyanins, with beneficial effects on organ weight and lipid profiles.

Objective; Host, pathogens and environments are factors of creating dental caries. Dietary factor among environmental factors is affected by sugar contents and viscosity of food. The purpose of this study was to evaluate the viscosity and sugar contents of the Army Meal-Ready-to-Eat(MRE) and calculate the cariogenic potentiality index(CPI). Method; 7 types of MRE including hardtack were studied in the present study. Viscosity and sugar contents of each MRE were measured for 3 times by viscometer and glucose measuring machine. Cariogenic potentiality index was calculated by the formula[Cariogenic potentiality index(CPI) = 2.581343×sugar contents + 0.598324×viscosity]. Results; Army MREs had the high cariogenic potentiality index were special 1, special 3, special 2, type I 3, hardtack, FRH(Flameless Ration Heater), type S in order. Conclusion; Some of Army MREs have the high cariogenic potentiality index and may deteriorate the oral health condition of military personnel. It is recommended that broader and clinical studies are necessary to evaluate the effect of Army MRE on the oral health condition.
