Dietary sodium intake is considered one of the major causal factors for hypertension. Thus, to control the increase of blood pressure and reduce the risk of hypertension-related clinical complications, a reduction in sodium intake is recommended. The present study aimed at determining the association of dietary sodium intake with meal and snack frequency, snacking time, and taste preference in Korean young adults aged 20-26 years, using a 125-item dish-frequency questionnaire. The mean dietary sodium intakes of men and women were 270.6 mmol/day and 213.1 mmol/day, which were approximately 310% and 245% of the daily sodium intake goal for Korean men and women, respectively. Dietary sodium intake was positively correlated with systolic blood pressure in the total group, and BMI in the total and men-only groups. In the total and men-only groups, those who consumed meals more times per day consumed more dietary sodium, but the number of times they consumed snacks was negatively correlated with dietary sodium intake in the total, men-only, and women-only groups. In addition, those who consumed snacks in the evening consumed more sodium than those who did so in the morning in the men-only group. The sodium intake was also positively associated with preference for salty and sweet taste in the total and women-only groups. Such a high intake of sodium in these young subjects shows that a reduction in sodium intake is important for the prevention of hypertension and related diseases in the future.

본 연구는 새터민들의 편의식품에 대한 선호도와 이용현황을 파악하여 올바른 편의식품을 선택할 수 있게 하고자 실시하였다. 새터민 211명에게 설문지를 조사하여 SPSS를 이용해서 분석했다. 반 이상의 새터민들이 편의식품을 좋아하고, 즐겨먹는 것으로 조사되었다. 반 정도의 새터민들이 편의식품에 대해 경우에 따라 좋다고 생각하고 있었고, 새터민들은 편의식품을 간식으로 즐겨 먹었다. 새터민들은 영양보다는 편리성과 맛 때문에 편의식품을 선택하고 있다. 새터민들은 거주기간이 짧을수록 패스트푸드의 맛, 편리성, 영양, 가격때문에 패스트푸드를 선택하는 경향을 보였다. 새터민들에게 편의식품에 대해 이해시키고, 올바른 편의식품 사용방법에 대해 기초적인 식생활교육을 실시하는 것이 바람직하다고 생각되었다.

The objective of this research was to assess the dietary habits, food frequency, and nutrition knowledge of young children who like sweets in the Busan area; the study was conducted using survey method with questionnaires. One hundred eighty three children, aged 8 to 9 years, were divided into two groups: the sweet preference group (SPG) and the control group, based on the subjects' scores for sweets-related dietary habits, sweets preference, and sweets frequency. For dietary habits, the score for eating more snacks than meals was significantly higher in the SPG group than the control group. The SPG group members were also more likely to skip breakfast, have irregular meals, and consume instant and fast food more frequently (p<0.001) than the control group. Nutrition knowledge scores for proper snack intake and proper dietary attitude were significantly lower in the SPG than in the control group (p < 0.05). With regard to food frequency, the SPG consumed more bread, cake, chicken, ham, sausage, hamburger, and ice cream, but less fish, tofu, beans, kimchi, bean sprouts, and milk than the control group. Strong positive correlations were noted between sweets preference, sweets frequency, and sweets-related dietary habits, whereas all of them were correlated negatively with nutritional knowledge. Sweets frequency was related negatively to meal regularity, having breakfast, eating the adequate amount of meals, and recommended food frequency.

Objectives: This study examined ways to promote desirable eating habits by choosing foods with low sugar contents and provide nutrition education in adolescents. Methods: This study was a cross-sectional survey. The sugar reduction perception and knowledge, sugary food preference, and intake frequency of 487 male and female high school students in Incheon were analyzed comparatively. Results: Approximately 94.9% and 94.5% of the subjects were unaware of the promotion of a sugar reduction policy and the sugar reduction in the basic guidelines for school meals, respectively. Approximately 95% of them had not received any sugar reduction nutrition education, and 90% were not interested in sugar reduction. The perception for sugar reduction was significantly higher in girls (3.43 out of 5 points) than in boys (3.16 out of 5 points) (P < 0.001). Knowledge about sugar was 3.65 out of 6 points in girls and 3.04 points in boys (P < 0.001). The preference and intake frequency for fruits of the total students were 4.24 out of 5 points and 2.56, respectively. For beverages, the preference was significantly higher in boys (3.97 points) than in girls (3.70 points) (P < 0.001), and the intake frequency was significantly higher in boys (2.26 points) than in girls (2.08 points) (P < 0.001). The preference for snacks was significantly higher for girls (4.19 points) than boys (4.02 points) (P < 0.01), and the intake frequency was 2.22 points in boys and 2.17 in girls, showing no significant difference. Sugar reduction perception and knowledge about sugar showed significant negative correlations with the snack intake frequency (r = -0.11, P < 0.05; -0.13, P < 0.05) after adjusting for gender, grade, and body mass index. Conclusions: The high school students' perception of sugar reduction was very low, and there was a significant correlation with sugary food intake, suggesting that the sugary food intake will decrease as the sugar reduction perception and knowledge about sugar increase.

동결김치분말을 첨가한 김치스낵을 만들기 위하여 김치의 적숙에 영향을 미치는 pH와 산도 변화를 5일 간격으로 측정한 결과 담근지 2주일 전후의 pH 4.0-4.7, 산도 0.5%-0.8% 사이에서 김치의 일반적인 적숙기로 판단되었으며, 그 후 김치를 동결건조 하여 김치스낵의 원료로 사용하였다. 김치스낵 반죽은 밀가루를 기준으로 control군과 각각 2, 4, 6, 8%의 동결김치분말을 첨가하여 성형한 만든 다음 $170^{\circ}C$ 정도의 온도에 2분간 튀겨 스낵을 완성하여 각각의 제품에 대한 관능적 특성을 살펴본 결과 김치스낵의 color, kimchi tasty, nutty, overall 등을 고려하여 동결김치분말 4%첨가가 가장 적당한 것으로 판단되었다. Automatic thermal desorber 장치를 이용해 휘발성 성분을 포집하여 분석한 결과 26종의 성분이 분리 동정되었으며, 분리 동정된 화합물들 중에서 aldehyde류 13종, ketone류 1종, 함황화합물 3종, acid류 1종, terpene류 1종 기타화합물 7종류를 동정하였다. 동결김치분말을 첨가한 김치스낵은 4개 시료 모두 휘발성 향기성분의 종류에서의 차이는 크게 나타나지 않았으며 이를 더욱 자세히 살펴보기 위해, 김치분말 농도의 변화와 휘발성 성분의 상관관계를 피어슨 상관관계를 이용하여 살펴보았다. 피어슨 상관관계가 0.90 이상의 값을 보이는 휘발성 성분은 acetaldehyde, propanal, dimethyl sulfide, dimethyl disulfide, acetic acid, d-limonene 이었다. 피어슨 상관관계가 0.90 이상으로 높게 나타난 화합물을 특정한 분자량으로 정량분석에 쓰이는 방법인 SIM 방법으로 분석한 결과 각각의 휘발성 성분에 대한 피어슨 상관계수는 모두 0.97 이상으로 나타나서 높은 관계성을 보여주었으며 본 실험을 통하여 김치 스낵에 있어서의 냄새의 차이를 보이는 지표 성분으로 판단되어진다.

Two kinds of steamed sweet potatoes were dried with mild hot air to improve quality, convenience and preference as a snack. Steamed sweet potatoes were dried at temperatures ranging from 35 to $65^{\circ}C$ for 12 hr, and moisture contents, colors, texture, and taste were evaluated. The lowest moisture content was 0.25% at $65^{\circ}C$. Color values (L, a, b and ${\Delta}E$) decreased with increasing drying temperature and drying time in both chestnut-sweet potatoes and pumpkin-sweet potatoes. Reducing sugars and soluble solids increased quickly at high drying temperatures. The highest hardness value for chestnut-sweet potatoes was $26.31\;kg_f /cm^2$when they were dried at $65^{\circ}C$ for 12 hrs. Springiness and cohesiveness were higher than those in chestnut-sweet potatoes. The highest taste score was for a dried chestnut-sweet potatoes at $55^{\circ}C$ for 6 hr and a dried pumpkin-sweet potatoes at 45 or $55^{\circ}C$ for 6 hr.

Recently, though mulberry's superiority as a functional food has been proven, its use as a food material is limited. Therefore, in this study, to develop jelly using mulberry that is compatible with Korean tastes as health functional food by grafting the method to manufacture jelly consumed as a dessert or a snack in the west, according to the central composite design, mulberry jelly was produced by varying the content of citric acid ($X_1$), sucrose ($X_2$), and gelatin ($X_3$) at 5 levels. And by applying the response surface methodology, rheology and sensory preference experiment results were analyzed, the optimization of mulberry jelly manufacturing condition was carried out, and studies on the analysis of composition were performed. As the sensory preference of mulberry jelly, except the flavor, the remaining hardness, elasticity, sweetness, color, and the overall quality were found to be significant. And similarly, it was found to be influenced greatly by gelatin content generally. Based on the overlapped part of categories, in the range of factors that satisfy all the sensory categories, the value located in the middle was calculated, the optimization point was obtained, and it was found to be 6.2 g citric acid, 141.0 g sugar, and 13.5 g gelatin.
