  • 본 연구는 성인영양지수 조사지를 바탕으로 북한이탈주민의 전반적인 식사의 질을 평가하고자 진행되었다. 특히 연령대별 식품 섭취 빈도와 식습관 및 식행동, 영양 지수의 차이를 분석하였다. 대상자는 서울 및 경기 일부 지역의 만 19-64세 성인 166명을 대상으로 진행되었으며 각 연령대별로 20대 41명, 30대 41명, 40대 41명, 50대이상 43명으로 연령대를 평준화하였다. 연령대가 낮을수록 라면, 패스트푸드, 과자 (초콜릿, 사탕 포함), 달거나 기름진 빵 (케이크, 도넛, 단팥빵 등), 가당 음료 등 고에너지 식품 섭취 빈도와 외식, 야식 섭취 비율이 높은 것으로 나타났다. 또한 20대 연령대에서 총점 NQ, 절제 영역 총 점수가 낮고 등급은 '하'로 판정된 비율이 높았다. 50대 연령대에서 절제영역의 점수가 높게 나타난 원인은 라면, 패스트푸드, 과자, 달거나 기름진 빵, 가당 음료 등과 같은 고에너지 식품 섭취 빈도도 낮기 때문인데, 이는 이 집단이 절제력있는 식사를 하고 있는 것으로 비춰질 수도 있으나 중년층에서 패스트푸드, 라면과 같은 식품의 기호도가 낮아 아예 섭취 고려 대상이 아니라는 점에 주목해야 한다. 본 연구에서 주목해야 할 점은 연령이 낮을수록 식사의 질이 매우 열악하게 나타나 식사의 질 개선을 위한 맞춤형 영양 교육 프로그램 개발 및 보급의 필요성을 시사한다. 이에 본 연구의 결과와 시사점이 북한이탈주민의 건강 증진을 위한 영양 교육과 이를 위한 정책 마련의 기초자료로 활용되기를 기대한다.

  • This study was performed to examine the functional and quality characteristics of rice cookies with added Ligularia fischeri (Ledeb.) Turcz. powder. Rice cookies were prepared with different amounts (0%, 0.5%, 1%, 1.5% and 2% to the flour quantity) of Ligularia fischeri powder. The antioxidant activities of Ligularia fischeri powder, specifically the total phenolic content, DPPH free radical scavenging activity and reducing power were found to be 212.19 mg GAE/g, $11.78{\mu}g/mL$11.78 ($IC_{50}$), and 2.33 (O.D.), respectively. The antioxidant activities of the rice cookies with added Ligularia fischeri powder increased with increasing concentrations of Ligularia fischeri powder. Regarding the hunter's color value of rice cookies with added Ligularia fischeri powder, L (lightness) and a (redness) values decreased (p<0.001) with increasing concentrations of Ligularia fischeri powder, whereas b (yellowness) values increased (p<0.01). The consumer acceptability score for the 3% Ligularia fischeri rice cookie groups ranked significantly (p<0.001) higher than the other groups in color, flavor, taste, texture and overall preference. These results suggest that Ligularia fischeri powder will be useful as a functional food resource with antioxidant activities.

  • 고춧가루를 첨가하여 토마토소스를 제조한 후, 품질특성을 조사한 결과는 다음과 같다. 수분은 고춧가루의 첨가량이 증가함에 따라 감소하였으며, 조단백, 조지방, 조회분, 탄수화물은 증가하였다. pH는 고춧가루 첨가량이 증가함에 따라 감소하였으며, 이는 유기산 감소에 의한 것으로 판단된다. 색도의 경우 L값, a값은 감소하였으며, b값은 증가하였다. Lycopene과 ${\beta}$-carotene은 고춧가루가 첨가됨에 따라 높아졌는데, 토마토뿐 아니라, 고춧가루의 적색도에서 카로티노이드계 색소를 포함하고 있으며, 이에 따라 높아진 것으로 판단된다. 총 폴리페놀과 총 플라보노이드, DPPH radical 소거능 또한, 첨가량이 증가함에 따라 높았으며, 고춧가루가 가지는 항산화물질에 의한 것으로 보여진다. 고춧가루를 첨가한 토마토소스의 저장 기간에 따른 총 균수의 변화를 측정한 결과, 총 균수는 모든 시료에서 대부분 기간이 증가함에 따라 증가하였다. 고춧가루를 첨가하지 않은 con에 비해 3% 첨가한 TC3와 5% 첨가한 TC5 시료는 15일까지 3,500 cfu/g, 1,200 cfu/g 수준으로 다른 시료들에 비하여 상대적으로 안정적인 형태를 보였으며, 이후 20일, 25일, 30일까지 총 세균수는 급증함을 알 수 있었다. 이는 고춧가루의 첨가량이 높을수록 미생물의 생육을 억제하는 데 긍정적인 역할을 하는 것으로 판단된다. 특성차이 검사에서 표면의 매끄러움 정도는 첨가량이 높아짐에 따라 낮은 강도를 보였으며, 입자감에서는 높은 강도를 보였는데, 고춧가루가 토마토 수분을 흡수하게 되면서 소스의 농도가 높아진 것에 따른 것으로 판단된다. 소스만 기호도 측정한 결과, 모든 항목에서 고춧가루 2% 첨가한 TC2가 높은 기호도를 보였으나, 파스타면과 함께 측정한 결과, 3% 첨가한 TC3에서 가장 높은 기호도를 보였다. 고춧가루 첨가한 토마토소스 제조 시 고춧가루의 첨가량은 3%가 가장 적합한 것으로 사료되며, 고춧가루를 첨가시킨 매운 맛의 토마토소스는 토마토 가공 제품으로서 경쟁력이 있을 것으로 보여진다.

  • BACKGROUND/OBJECTIVES: The objective of this study was to describe the development process of the Korean Healthy Eating Index (KHEI) based on the Korea National Health and Nutrition Examination Survey (KNHANES). SUBJECTS/METHODS: The components of KHEI were selected based on Dietary Guidelines for Koreans, domestic and overseas dietary quality indices, and results of the analysis of association with chronic diseases. The standards for scoring of KHEI were selected based on the 2015 Dietary Reference Intakes for Koreans (KDRI). The KHEI scores of Korean adults were calculated using a 1-day 24-h recall data in the 2013-2015 KNHANES. RESULTS: The KHEI included eight adequacy components evaluating the proper intake of recommended foods such as fruit, vegetable, and milk and three moderation components evaluating the consumption of food that limit intake such as sodium and saturated fatty acid. In addition, three balance components assessing the balance of energy intake were included. The KHEI score was defined to range from the minimum of 0 point to the maximum of 100 points. Among Korean adults, the total KHEI score was 63.2 out of 100. Gender and age differences were found in the average of total KHEI scores. Women showed higher score than men (61.7 in men and 64.7 in women, respectively). By age group, 20s and 30s showed the lowest scores with 57.4 and 61.1 respectively, and the scores increased with age by peaking at 67.8 in ages 60-69 and slowed down again in ages 70 or over. CONCLUSIONS: The KHEI can be useful for establishing and assessing national nutritional policies and in epidemiological studies to assess the relationship between overall dietary quality and chronic diseases. KHEI will need to be continuously updated to reflect changes in dietary guidelines and the KDRI.

  • The purpose of this study was to identify the factors of university residence hall foodservice quality which has correlations with subjective QOL (quality of life) of target customers. A total of 176 questionnaires from students of 4 universities in Daegu, Gyeongbuk area were used for the analysis. The male students using residence hall foodservices were highly satisfied with 'clean appearances of employees' ($4.86{\pm}1.25$) and 'clean facilities' ($4.79{\pm}1.26$), while the degree of satisfaction with 'convenient facilities' ($4.50{\pm}1.20$) showed the highest score with female students. Ranking analysis using Spearman's ${\rho}$ revealed that there were significant correlations between students' satisfactions with the dimensions of 'foods and kindness of employees', 'hygiene', 'nutrition', and 'convenience' and their QOL, even though physical QOL of female students showed no significant correlation with satisfaction towards residence hall foodservices. As a conclusion, there should be efforts to improve the QOL of target customers through foodservice quality management.

  • A linear correlation was found by stepwise multiple regression analysis between the sensory score of barley bran sauce aroma and the absolute gas chromatogram (GC) data transformed with square root. In spite of highly significant relationship between the quantity of the peak and the sensory score, it is difficult to estimate the aroma quality of barley bran sauce samples on the basis of only one peak. Peak 29 (methyl 9,12,15-octadecatrienoate) contributed most to the aroma of barley bran sauce. This was followed by 27 (methyl 9,12-octadecadienoate), 28 (ethyl 9,12-octadecadienoate), 12 (phenyl acetaldehyde), and 9 (methyl furfural) in terms of absolute value. When it was calculated using absolute value transformed by square root, peak 28 (ethyl 9,12-octadecadienoate) made the highest contribution to the aroma of barley bran sauce of among the peaks. It was followed by 31 (9,12-octadecadienoic acid), 27 (methyl 9,12-octadecadienoate), 12 (phenyl acetaldehyde), and 29 (methyl 9,12,15-octadecatrienoate).

  • The purpose of this study was to identify the relationship between the levels of job satisfaction and self-evaluated foodservice quality of dietitians in elementary schools. Out of 130 questionnaires distributed to the elementary school dietitians in In-cheon, 127 were returned and analyzed (98% response rate). The questionnaire included two multiple-item scales for measuring job satisfaction and foodservice quality, respectively. All the items in the scales were coded 1 to 5 for certainly no, no, neutral, yes, and certainly yes and grouped by using factor analyses. Most of the responding dietitians were working for schools in urban areas and had independently-managed on-site kitchens. The 23 items measuring job satisfaction were grouped into 4 factors: Job Duty, Job Condition, Physical Work Environment, and Organizational Environment. The satisfaction score was the highest for Organizational Environment with a value of 3.38 and the least for Physical Work Environment with a value of 2.08. The 22 items measuring foodservice quality were grouped into 5 factors and the mean scores of the levels of Cleanliness, Internal Food quality, External Food quality, Intangible Service Environment and Tangible Service Environment were 4.20, 3.89, 3.54, 3.45 and 2.64, respectively. The levels of job satisfaction and foodservice quality were positively associated with a correlation coefficient of 0.288 (p < 0.01). In particular, the level of job satisfaction was positively associated with foodservice quality in the aspect of Cleanliness, Internal Food Quality, and Intangible Service Environment. The results show that improving dietitians' job satisfaction could contribute to increasing the levels of foodseivice quality of elementary schools.

  • BACKGOUND/OBJECTIVES: This study investigated nutritional status of the elderly with dementia in a care facility with the aim of improving the meal quality of the facility. SUBJECTS/METHODS: Data were collected from 30 dementia patients aged more than 65 years in a long-term care facility in Hongseong. The data were obtained from questionnaires and medical records. The food intake data was obtained using food photographs and the nutrient intakes were calculated using the CAN-Pro 5.0. The data were compared with the dietary reference intakes for Koreans (KDRIs). The nutrient density, diet quality such as nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ), as well as dietary diversity score (DDS) were evaluated. The data were analyzed using SPSS statistical programs. RESULTS: The average daily energy intakes for men and women were much lower than the estimated energy requirements of the KDRIs. The average intakes of energy and most nutrients in the general diet group were significantly higher than those of the other two groups. Significant differences in diet quality and diet diversity were observed according to the meal type groups. The NARs of some minerals (calcium, iron, and zinc) and vitamins (vitamin $B_6$ and folic acid) were less than 0.5 in all study groups. The NARs of protein, iron and MAR of the general diet group were significantly higher than those of the liquid diet group. The DDS scores of meats, fruits and diary food group were very low in all meal type groups, meaning that the diet qualities of the study subjects were not appropriate in all meal type groups. CONCLUSIONS: The food intakes of the study groups showed some limitations by a direct comparison with KDRIs because of the very low physical activities of the study subjects. The diet quality and diet diversity indices suggest the need for improvements in the nutritional quality in all types of diet. Overall, new intervention strategies targeting facility residents with dementia in Korea are needed as soon as possible.

  • The present study was performed to develop healthier sweeteners for brown rice Dasik with chia seed powder. The quality features and sensory evaluation were tested for brown rice Dasik with chia seed powder added with five different sweeteners and the results are as follows. The Dasik (DS) with isomalto-oligosaccharide and starch syrup received the highest scores on moisture content tests. The results from hardness tests identified the DS with agave syrup as the hardest, and the results from the adhesiveness test verified that the DS with agave syrup as well as the DS with starch syrup produce the most adhesive DS. The results of the springiness test show that the DS with starch syrup has higher springiness than other sweetners. The highest score for the chewiness and cohesiveness tests was the DS with starch syrup, while the DS with isomalto-oligosaccharide received the highest score on the gumminess test. The results of the chromaticity measurement test found that the DS with starch syrup showed the highest score of 'L' and the lowest score with fructo-oligosaccharide. In addition, the highest score of 'a' was DS with isomalto-oligosaccharide and the lowest score of 'b' was the DS with starch syrup. The results of sugar content displayed that the DS with starch syrup was the highest and the DS with fructo-oligosaccharide was the lowest score. The results of sensory evaluation verified that color did not influence evaluators' preference investigation. The results of sweet flavor test found that the DS with honey and the DS with agave syrup had the most preferred by participants, but there was no statistically significant difference among all five different sweeteners from the sweet taste test. Furthermore, the DS with agave syrup received the highest score while the DS with agave syrup scored the lowest from the hardness preference test. General preference evaluation identified the highest score with the addition of fructo-oligosaccharide and the lowest score with the addition of isomalto-oligosaccharide. Thus, the findings of the present study provide the meaningful results to demonstrate the DS with fructo-oligosaccharide is the most suitable sweetener to manufacture brown rice DS added by chia seed powder, and this result will help marketers with creating meaningful strategies and with developing similar products using chia seed powder.
