The intake of processed foods containing high levels of sugar increases the incidence of chronic diseases, including obesity, diabetes, and metabolic syndrome. Limiting sugar intake is important for a healthy life at all ages. Therefore, this study analyzed food sources and sugar intake by the different age groups based on the 7th Korea National Health and Nutrition Examination Survey (KNHANES). We used 24-hour recall survey data to investigate the daily sugar intake and the major food groups and main dishes contributing to sugar intake. The mean sugar intake was 58.9-66.8 g/day. The three major food groups contributing to sugar intake were fruits (15.2-19.9 g/day), beverages (10.7-12.4 g/day), and milk and milk products (7.6-7.8 g/day). Teas and other non-alcoholic beverages (14.7-17.3 g/day), fruits (12.5-16.2 g/day), and dairy products (7.0-7.6 g/day) were the major food groups that contributed to the sugar intake. Carbonated drinks, apples, and milk were the top sources of sugar intake in each group. In conclusion, the sugar intake of Koreans is mainly from carbonated drinks, fruits, and milk. These results provided the basic data for nutrition education and nutrition program development according to the different age groups of the Korean population.

유통 당류(n=124)에서 C4슈가 혼입여부를 확인하기 위하여 탄소동위원소비율(δC), 당조성, 인공감미료를 분석하였다. 탄소동위원소비율 분석 결과, 유통벌꿀(n=23) 중 3 건(13.6%)에서 C4슈가가 혼입된 것으로 판정되었고 도시 영농으로 제조된 벌꿀(n=23)은 모두 식품공전의 기준에 적합하였다(-26.09– -22.99‰). 사양벌꿀(n=11)의 탄소동위원 소비율 범위는 -14.58에서 -11.52‰로 C4당의 특성을 보였다. 코코넛슈가(n=20)의 δC값은 -25.72에서 15.87‰로 3건에서 C4당류가 혼입된 것으로 판단되었다. 단백질침전 법으로 C4당의 함량을 확인한 결과, 모든 코코넛슈가에서 C4당이 최저 9.5%에서 최고 63.4% 검출되었다. 메이플시럽 (n=12) 중 1건이 AOAC의 메이플 시럽 기준에 부합되지 않았다. CAM 당류인 아가베시럽(n=12)은 -11.42에서 - 10.92‰ 범위로 C4당류와 범위가 겹쳐서 추가 연구가 필요하다. C4당인 사탕수수당(n=10)의 탄소동위원소비율은 -12.60에서 -11.40‰이었고, 옥수수물엿(n=5)은 -11.70에서 -10.93‰이었다. Fructose/glucose 비율 측정 결과, 일부 아가베시럽에서 혼입이 의심되었다(3.2-49.7). 모든 시료에서 인공감미료는 검출되지 않았다.

The aging treatment was applied to Rehmannia glutinosa rhizome (RGR) to improve the digestibility by the enzymatic hydrolysis of undigestible sugars. However, RGR spoils easily during the aging treatment. Thus, the purpose of this study was to investigate the influence of ethanol addition as preservatives on sugars and microbial growth of aged RGR. The RGR was treated with the addition of ethanol (0~10%) at 55℃ for eight days. Reducing, free sugars, and total bacterial counts of RGR with ethanol concentrations were analyzed during the aging periods. The aged RGR with 0-2% ethanol appeared spoiled in appearance, and total bacterial counts of these samples increased from 1.1×105 to 2.2×107 CFU and then decreased again. When treated with 4~10% ethanol, the total bacterial counts of aged RGR decreased by more than 99.9% at eight days. In all samples, reducing and digestible sugars increased, and stachyose decreased by the aging treatment. Sucrose content was highest in the 6% ethanol sample (18.2% at six days). These results indicate that the ethanol addition can be applied to the aging treatment of the RGR for improving qualities (sweetness, digestibility, and microbial growth), and can be considered for the stable production of high quality aged RGR.

This study was conducted to investigate the effects of sugars and stabilizers on the qualitative properties of frozen-yogurt. To prepare the yogurt mix, market milk was fermented using a commercial starter culture and sugars, trehalose and sucrose, and to prepare the ice cream mix, stabilizers, carboxy methyl cellulose (CMC) and guar gum, were used. The yogurt and ice cream preparations were mixed in a 1:1 (v/v) ratio to produce frozen-yogurt. Yogurt prepared using trehalose showed a significantly faster increase in pH, titratable acidity, and viable cell count than that prepared using sucrose (p<0.05). Ice cream prepared using guar gum showed a significantly higher viscosity and overrun than the CMC-stabilized preparation (p<0.05). Frozen-yogurt produced using the yogurt-trehalose mix and ice cream-CMC mix showed the highest hardness and lowest overrun. The melt-down rate of frozen-yogurt prepared with the yogurt-trehalose mix was significantly slow (p<0.05). However, there were no significant differences among the yogurt mixes in terms of changes in the viable cell count at 0, 7, 15, 30, and 45 days (p>0.05). In a sensory evaluation, most panels preferred the frozen-yogurt with sucrose over that with trehalose. However, it is expected that using trehalose with other sugar substitutions and guar gums in manufacture of frozen-yogurt have high potentiality than using sucrose and CMC, and it is considered that it could reignite the stagnant domestic milk processing industry.

본 연구는 국민건강영양조사 제6기 자료를 이용하여 한국인의 가공식품 유래 당류 섭취율이 높은 사람의 특성을 분석하고, 당류 섭취율에 영향을 주는 요인에 대해 분석하였다. 이를 위해 군집분석과 일원배치분산분석(ANOVA)을 사용하여 통계적인 차이 유무를 분석하였다. 주요 분석결과는 다음과 같다. 첫째, 군집분석을 활용하여 분석대상자의 당류 섭취율을 5개 집단으로 나누었다. 가장 낮은 섭취율군은 전체 섭취 열량 중 약 3.89%를 가공식품에서 유래하는 당류로부터 섭취하고 있다. 이에 비해 가장 높은 군은 하루 평균 약 34.23%를 나타내었다. 둘째, 인구사회학적 특성 중 당류 섭취율이 높은 집단은 통계적으로 남성보다 여성이, 나이가 적을수록, 교육수준이 낮을수록, 가구원수가 많을수록, 키가 작을수록, 체중이 작게나갈수록, 허리둘레가 작을수록, BMI가 작을수록 당류 섭취율이 높은 것으로 나타났다. 셋째, 행동특성에서는 음주빈도가 낮을수록, 스트레스 인지가 많을수록, 고혈압, 당뇨병, 고지혈증 진단을 받지 않을수록, 아침 및 저녁 식사 빈도가 작을수록, 영양교육을 받지 않을수록, 영양표시 이용을 하지 않을수록 당류 섭취율이 높은 것으로 나타났다. 결론적으로 한국인의 가공식품 유래 당류 섭취율에는 성별, 나이, 교육수준 등 인구사회적 특성과 음주, 스트레스, 아침 및 저녁 식사 빈도, 영양 교육 등 행동특성이 영향을 미치는 것으로 나타났다. 식품위생법 제70조의 7에는 식품의 나트륨, 당류, 트랜스지방 등의 영양성분을 건강위해가능 영양성분이라고 정의하고 있으며, 이들의 과잉섭취로 인한 국민보건상 위해를 예방하기 위해 노력해야 한다고 하고 있다. 이를 위해 식품의약품안전처는 적정섭취 실천방법 교육 및 홍보, 모니터링 및 정보제공, 이들을 줄인 급식과 외식, 가공식품 생산 및 구매 활성화 등의 사업을 운영 또는 계획 중에 있다. 국민보건 상 위해를 예방하기 위해서는 본 연구에서 도출된 가공식품에서 유래한 당류 섭취율이 높은 사람의 특성을 반영한 차별화된 소비자 교육 및 홍보가 우선되어야 한다. 이를 통해 당류 섭취율이 줄일 수 있으며, 나아가 국민 건강 증진에 기여할 수 있다고 판단된다.

본 연구는 어린이급식소를 대상으로 체계적인 위생관리 및 영양관리를 지원하고 있는 어린이급식관리지원센터 기반 유아 당류 줄이기 교육프로그램 개발 및 운영을 위한 기초자료 마련의 일환으로 센터의 예산규모에 따른 유아 당류 교육실태 및 요구도를 비교․분석하였다. 본 조사는 2015년 10월 온라인 설문조사를 통하여 전국 115개 어린이급식관리지원센터의 팀장 또는 팀원을 대상으로 이루어졌다. 센터의 예산규모에 따라 1~2억원 센터(21.7%), 3~4억원 센터(52.2%), 5~7억원 센터(26.1%)로 분류하였다. 1~2억원 센터는 읍면지역이 72.0%로 가장 많았고, 3~4억원 센터와 5~7억원 센터는 대도시가 각 46.7%, 56.7%로 가장 높아 유의적인 차이를 보였다(p<0.001). 유아 대상 당류 섭취 줄이기 교육 실태조사 결과, 교육을 실시하는 비율은 1~2억원 센터 8.0%로 낮았고, 3~4억원 센터의 경우 16.7%, 5~7억원 센터의 경우 16.7%로 예산규모에 따른 유의적인 차이를 보였다(p<0.05). 유아의 당류 섭취 관련 영양교육을 실시하지 않는 이유에 대하여 조사한 결과, 1~2억원 센터는 ‘영양교육 자료 부족’이 47.1%로 가장 많았고, 3~4억원 센터와 5~7억원 센터는 ‘당류 교육보다 더 시급한 영양교육 내용이 많음’이 각각 66.7%와 50.0%로 높게 타났다. 유아의 학부모를 대상으로 한 유아 당류 섭취 관련 영양교육 실시여부를 조사한 결과, 실시 비율은 1~2억원 센터가 8.0%로 가장 낮았고, 3~4억원 센터 28.3%, 5~7억원 센터 23.3%로 예산규모에 따른 유의적인 차이를 보였다(p<0.05). 유아 당류 줄이기 교육의 필요성에 대한 조사에서 ‘매우 필요하다’와 ‘필요하다’의 비율이 예산규모에 따른 유의적인 차이 없이 90% 이상 높게 나타났다. 유아를 대상으로 한 효과적인 교육방법에 대한 질문에 대하여 예산 규모에 상관없이 75% 이상의 높은 비율을 보인 것은 동화나 인형극을 활용한 교육 방법이었고, ‘영양교육 활동지를 통한 교육’은 1~2억원 센터에서 낮았고(p<0.05), ‘실험활동을 통한 교육’은 3~4억원 센터에서 낮았다(p<0.05). 효과적일 것으로 생각하는 유아 대상 교육 담당자로는 모든 센터에서 ‘어린이급식관리지원센터 영양사+담임교사’가 80.0% 이상으로 나 타났다. 이상을 통해 어린이급식관리지원센터에서의 유아 당류 섭취 관련 교육에 대한 필요성과 효과적일 것으로 생각하는 교육 방법 및 시간 등에서는 사업 규모별 차이가 없었지만, 교육 실태는 사업 규모에 따라 유의적인 차이를 보여, 1~2억원 규모의 소규모 센터의 경우 유아 당류 섭취 관련 교육의 실시율이 낮고, 교육 자료의 부족을 느끼고 있는 것으로 나타났다. 현재 어린이급식관리지원센터의 사업비 분배는 회원 어 린이집의수에 따라 1억원 단위로 비례적으로 정해지고 있다. 비록 본 연구는 영양교육 프로그램에 한정된 결과를 보여주고 있기는 하지만, 1~2억원 규모의 소규모 센터의 경우 예산 및 인력부족으로 사업의 운영에 어려움을 보이고 있고, 이로 인해 큰 센터에 비하여 상대적인 사업의 질 저하를 초래할 가능성이 높음을 보여준다. 그러나 소규모 센터의 경우, 인구가 적은 읍면 지역에 위치하는 경우가 많기 때문에 대상자가 여러 가지 사회․문화적 혜택으로부터 소외되어 있는 계층일 가능성이 높다. 따라서 국가에서 시행하는 사업에서 이러한 부분을 보완해야 할 책임 또한 더 클 것으로 사료된다. 따라서 사업의 규모에 따른 차이 없이 질적으로 평준화된 교육프로그램의 제공 및 소규모 센터의 예산 및 인력부족으로 인한 교육프로그램 개발 및 운영의 어려움을 해결하기 위해서 표준화된 유아 당류 섭취 줄이기 관련 교육프로그램의 개발 및 보급과 함께 어린이급식관리지원센터 사업 예산 분배에 대한 재고의 필요성이 큰 것으로 생각된다.

This study aimed to develop and evaluate a sugars intake reduction program (SIRP) that was designed to increase the knowledge, attitude, and skills of Korean children aged 5 years regarding sugars intake reduction. A total of 101 children aged 5~6 years from 6 preschools participated in SIRP. SIRP consisted of 4 sessions including 10 activities (e.g., story-telling, arts, experiment, checking nutrition facts, pledge), delivered to children at preschools by nutritionists over a one-month period. Three letters were sent to parents throughout the program to inform them of the children’s activities at the preschools and to provide additional information on reducing children’s sugars intake. A total of 90 children completed the program; 83 parents of these children completed the SIRP evaluation survey. The children’s sugars intake reduction score was significantly increased after attending SIRP. Teachers (n=6) who participated in this program agreed to improve their students’ attitudes on reducing sugars intake and to decrease students’ behaviors related to sugars intake. Parents agreed to improve their children’s attitude on reducing sugars intake and to decrease children’s behaviors related to sugars intake. The outcome showed SIRP improved participants’ attitudes towards sugars reduction and increased the skills to reduce the sugars intake of children aged 5~6 years. Future studies should examine whether SIRP reduces actual sugars intake among children.

This study examined the sweet taste perception, perception of sugar reduction, and utilization of nutrition labeling according to the awareness of the self-perceived sugar intake reduction of university students in Chungbuk Area. The subjects (n=419) were divided into two groups: Awareness of Sugar Intake Reduction (ASIR) group, male=110, female=109; Non Awareness of Sugar Intake Reduction (NASIR) group, male=115, female=85. The overweight/obesity was significantly higher in the ASIR group than in the NASIR group for both male and female students. The sweet taste perception was significantly lower in the ASIR group in male students than in the NASIR group. The purchase level of a product with reduced sugar instead of the original products was significantly higher in the ASIR group in male students than the NASIR group. Beverage purchases after identifying the sugar content were significantly higher in the ASIR group in male students than in the NASIR group. The necessity of nutrition labeling education was significantly higher in the ASIR group both male and female students. Based on these results, the correct perception of sugar reduction and continuous and practical nutrition education of sugar intake reduction need to maintain healthy dietary habits in university students.

The purpose of this study was to provide the basic information for developing sugar related nutrition education programs for children in child-care facilities and their parents. The results showed that the total score of parent’s dietary attitudes towards sugar-rich foods was 17.94 and the total score of parent’s nutritional knowledge was 3.67. A positive relationship was observed among items of parent’s dietary attitudes (p<0.01), and some correlations were also observed between the total score of parent’s nutritional knowledge and the total score of parent’s dietary attitudes (p<0.05 or p<0.01). The total average score of children’s eating behaviors for sugar-rich foods was 23.98, and the item with the highest score was ‘I often eat candy, chocolate and jelly’. For children, food that received the highest preference was chocolate, and soft drinks received the lowest preference. The most frequently consumed food item was candy or caramel, and the least frequently consumed food item was soft drinks. There were positive correlation among the total score of children’s eating behaviors, food preferences, and food intake frequency (p<0.01). When parent’s tried to reduce the sugar intake, children’s total score of eating behaviors (p<0.001) and food intake frequency (p<0.001) for sugar-rich food was lower. We conclude that parent’s dietary attitudes may influence children’s eating behaviors, food preferences, and food intake frequency for sugar-rich foods.

This study investigated the current status and needs for nutrition education to help reduce children’s sugars intake at the Center for Children’s Foodservice Management (CCFM, n=115), and Child Care Facilities (CCF, n=646) through an online survey conducted from October 5th to 30th 2015. A total of 14.8% of CCFM respondents and 31.9% of CCF respondents provided nutrition education on sugars intake to young children as a main topic (p<0.001). A higher percentage (CCFM 47.8%: CCF 42.4%) delivered nutrition education on sugars intake to young children as a sub-component (p<0.001). Over 90% of the CCFM and CCF participants agreed on the necessity of providing nutrition education on sugars intake to children. The most common reasons given for delivering nutrition education on children’s sugar intake were “there are many more urgent nutrition education topics” for CCFM, and “insufficient nutrition education information and materials” for CCF. The percentage of nutrition education on children’s sugar intake provided to the children’s parents was low showing about 20% in the both groups. The percentage of CCFM participants providing nutrition, education on children’s sugar intake to the teachers in CCF was also low, showing about 14.8%; however, 68.0% of the CCF participants wanted to received teacher's education on guiding children’s sugar intake. Regarding ideas about a nutrition education program on children’s sugar intake for young children, most respondents in both groups answered “sugar intake and dental cavities or obesity” for appropriate education contents, “story telling or puppet show” for appropriate education methods, and “dietitian from CCFM and class teacher together” for appropriate educator. For appropriate education time, there was a significantl difference between the CCFM responses (average 2.7 times) and the CCF responses (average 4 times). Based on the above results, we found that implementing nutrition education on children's sugar intake at the CCFM and CCF, was low; however, awareness of the need for nutrition education on children’s sugar intake and the program development and supply was very high. Also, the opinions of CCFM and CCF participants about a nutrition education program on children’s sugar intake for young children can provide foundation data to develop and implement the CCFM-based nutrition education program.

To determine sugars content of agricultural products and foods, simultaneous quantitative analysis was carried out on fructose, glucose, sucrose, maltose, and lactose by HPLC-RI. Analysis conditions were set as column ZORBAX carbohydrate (4.6 mm ID×250 mm, 5 μm), the mobile phase of 75% ACN, the column temperature of 35oC, sample injection amount of 10 μL and the flow rate of 1 mL/min. Five standard solutions were isolated without interfering peak within 30 minutes and the calibration curves of standard were confirmed excellent linearity from 0.10% to 1.00% with R2≥0.999. Based on the chromatogram of the standard solution, the limit of quantification (LOQ) and the limit of detection (LOD) values were calculated. The accuracy of the analytical values were highest at 100% water extraction method to the fructose 95.7%, sucrose 98.7%, lactose 102.7% respectively, compared with reference value of a certified reference material (BCR644), by applying the four solvent extraction methods. Using an in-house quality control material (infant formula), repeatability and reproducibility values of this experiment were verified on the basis of AOAC guideline and reference values were set up at 1.17 g/100g of glucose, 0.85 g/100g of maltose, and 45.54 g/100g of lactose. Quality control charts were drawn up and used for sugars analysis of agricultural products.
