소비자들은 건강에 관한 관심이 계속 증가할 것이며 이에 저열량 식품에 대한 요구에 부응하는 소재의 개발이 필요하다. 저열량 식품소재의 개발에 있어 열량을 낮춘 소재의 기능성과 최종제품의 품질을 잘 유지할 수 있는 관능성이 중요하다. 이에 난소화성 전분과 난소화성 말토덱스트린은 이러한 필요를 충족시킬 수 있는 소재이며 일반 식이섬유보다 다양한 제품에 품질을 자유롭게 조절할 수 있는 장점이 있다. 난소화성 전분은 입자가 작고 색이 하얗고 특별한 냄새와 맛이 없기에 제빵, 파스타, 시리얼, 스낵 제품 등에 식이섬유 함량을 높이거나 제품의 품질을 향상하는데 저열량 소재로 사용되고 있고 난소화성 말토덱스트린은 식후혈당 상승억제, 혈중 중성지방 개선, 배변 활동 원활하게 하는 기능성 원료이기에 음료, 건강보조식품, 일반 식품에서 저열량 소재로 많이 활용되고 있으며 앞으로도 다양한 저열량 식품에 소재로 활용될 것이다.

We attempted to determine whether energy density would influence calorie intake via cognitive cues, as reflected by satiety. This experiment was designed using two different energy density levels of Kimbab: normal Kimbab (1.6 kcal/g) vs low-density Kimbab (1.0 kcal/g). 26 female college students participated in this study. The subjects ate Kimbab in the lab once a week for 2 weeks. Each week at noon, they were served 24 units of either normal or low-density Kimbab, and we determined the units, grams, and calories of the real & cognitive intake of Kimbab, and also analyzed the satiety rate after eating Kimbab. Our results demonstrated that the real calorie intake from the low-density Kimbab was significantly lower than that of the normal Kimbab (290.3 kcal vs 474.4 kcal, p<0.001), but we noted no significant differences in the units and grams of real and cognitive intake between the normal and low-density Kimbab. However, despite consuming 39% lower caloric intake, the subjects reported similar levels of satiety rates with the two different density levels of Kimbab, as they did not perceive themselves to have eaten more normal Kimbab than low-density Kimbab. Thus, this study provides evidence that the energy density of food is a crucial determinant of caloric intake, and supports the notion that the consumption of low energy-dense foods may result in a reduction of caloric intake without altering satiety.

This study was examined closely physiological activation and intended to present the possibility of developing food low-fat food. Developing carbohydrate fat replacer as materials for low-fat food made of Korean potato starch, it is expected that the new demand of fat replacer will be created. Potato starch was modified by chemical modification. The calorie of starch of GPS was measured to be 3.0 kcal/g, those of chemically modified starch, HPR showed 2.5 kcal/g respectively, suggesting that calorie is decreased by modified treatment. The appropriateness of processing food was experimented by substituting the existing oil and fat containing food with gel of starch and modified starch in constant rate through utilization of modified starch. When producing mayonnaise by substituting edible oil with gel of modified starch in 10-50%, calorie was reduced by 44${\sim}$45% when substituted by 50%, suggesting the potential of low-fat food. Measuring viscosity of mayonnaise by Brookfield viscometer, the mayonnaise with HPR showed high viscosity and the chemical modified starch group of EZ also showed high viscosity. Generally, the material property of mayonnaise tended to reduce in all measured items when oil and fat are substituted by starch substituting materials and the substituting materials increase. When it comes to the emulsification stability of mayonnaise with starch substituting materials, emulsification stability of all mayonnaise with starch substituting materials is lower than that of compared group. While the group with NL as commercial fat replacer showed emulsification stability which was slightly higher than group with modified starch and the substitution group of HPR showed higher emulsification stability. Sensory evaluation for low-fat mayonnaise by substituting oil the products substituted by modified starch was more preferred than general starch substituting products such as GPS. While NL as commercially fat replacer showed the hight preference, products with H40, EZ were also highly preferred.

This study was intended to investigate the characteristics of muffins prepared with allulose which is low-calorie and physiologically functional rare sugar. Volume and specific volume of muffins increased significantly with allulose addition, but not with its contents. Muffin heights also increased as allulose was added more. Baking loss rate and moisture contents were not significantly different among samples. Allulose seemed to have nearly same water holding capacity with sucrose. Lightness of muffin crust and crumb both decreased, but redness and yellowness increased according to allulose, the reducing sugar addition by Maillard reaction. In the texture profile analysis, Hardness of AL100 was higher significantly (p<0.05) and springiness, cohesiveness and fracturability increased according to the allulose contents. In the sensory evaluation, AL0 was the sweetest and AL0 and AL25 got higher overall acceptance score. Physical characteristics were not different (p<0.05) among AL0, Al25 and AL50. As a result, 25% sucrose substitution with allulose can provide low-calorie, anti-hyperglycemic and tasty muffin.

This study surveys the state of 'children's snacks' sold within the Green Food Zone and that of High Calorie Foods with Low Nutrition Value (HCFLNV). The main purposes are the analyses of foods in accordance to KFDA Program for HCFLNV and an analysis of differences in HCFLNV that are dependent on relevant factors such as food types, school types, origins, the scale of manufacturing company, area and price. Based on the analyses, educational and political implications have been sought that will form nutritious dietary habits, contribute to the prevention of obesity, and improve health in child consumers. The methodologies of this study are literature studies and surveys. The results of this study can be summarized as following. First, the number of children's snacks is 517 items of total 645 gathered within 150 Green Food Zones. Candies are the most popular item, next are cookies, chocolates, and breads. Second, in the real state survey there are 186 HCFLNV (36.0%) among children's snacks sold within Green Food Zone. Based on the survey results, the marking of HCFLNV on the package of children's snacks and the extension of the ban of HCFLNV sales to all stores within the Green Food Zone are strongly suggested. This provides preliminary data related to children's snacks and food safety. With enforcement of the Special Act on the Safety Management of Children's Dietary Life, the rate of HCFLNV has decreased and the child snack product environment in stores has improved. However, it is necessary to supervise low-priced snacks and promote an awareness of HCFLNV along with the child consumer education of food safety is needed.

The aims of this study were to assess the quality of breakfast intake and to examine the relation of breakfast intake to the quality of daily diet in Korean school-aged children. The one day 24-hour recall data from the 2001 National Health and Nutrition Survey were analyzed. The sample of this study consisted of 1,600 children aged 7 to 18 years attending elementary, middle, or high schools. By calorie level of breakfast intake, the children were grouped into Breakfast Skippers (0 kcal; n = 268, 17%), Low Calorie Breakfast Eaters (0 kcal < and < 10% of Estimated Energy Requirement (EER); n = 190, 12%), Moderate Calorie Breakfast Eaters (10% ${\leq}$ and < 25% of EER; n = 861, 54%), or Sufficient Calorie Breakfast Eaters (${\geq}$ 25% of EER; n = 281, 17%). General characteristics including weight status and nutritional quality of breakfast and daily diet were compared among the four groups. The average daily calorie intake of Breakfast Skippers, Low, Moderate, and Sufficient Breakfast Eaters were 1,771 kcal, 1,719 kcal, 1,902 kcal, and 2,349 kcal, respectively; they were 86.3%, 85.9%, 98.0%, and 124.9% of EER, respectively. The percentages of students consuming daily diet with protein, vitamin A, $B_1$, $B_2$, niacin, vitamin C, calcium, phosphorus, or iron less than Estimated Average Requirement decreased in the breakfast groups with the higher calorie level of breakfast intake. The Dietary Variety Score of daily diet significantly increased by increasing the calorie level of breakfast intake. The results indicated the quality of daily diet was positively related to the level of calorie intake from breakfast.
