곡류의 기능성 소재를 바탕으로 칼로리가 낮고 조직감이 우수한 편의식 형태의 아침대용식 제품을 개발하기 위하여 9가지 곡물(옥수수, 통밀, 멥쌀, 흑미, 현미, 수수, 발아현미, 검은콩, 율무)을 이용하여 선식형과 퍼핑형 씨리얼바 2종류를 제조하여 수분함량, 색도, 조직감 등의 품질변화를 측정하였다. 씨리얼바의 제조는 9가지의 곡류 배합${\to}$부재료의 크림화${\to}$반죽${\to}$성형틀에 투입${\to}$굽기${\to}$냉각${\to}$견과류 토핑의 단계로 이루어졌다. 수분함량은 선식형 씨리얼바가 $9.4\%$, 퍼핑형 씨리얼바가 $10.1\%$였으며 색도 측정 결과 L값은 퍼핑형이 선식형보다 높았으며 a값은 프락토올리고당을 첨가한 선식형의 씨리얼바가 가장 강했으며 b값은 시료간에 유의적 차이를 보이지 않았다. 조직감에 있어 경도는 선식형보다 퍼핑형이 더 컸으며 선식형 씨리얼바의 경우에 프럭토올리고당을 첨가한 군이 가장 경도가 높았다. 관능검사 결과 전반적인 바람직성에 있어서 퍼핑형 씨리얼바가 선식형 씨리얼바보다 높은 기호도를 나타내었다.

Today, energy bars are consumed not only as snacks but also as meal replacement foods. Convenience and nutritional supplementation are the main factors accounting for the increasing use of energy bars. Two hundred Chinese customers who attended the China Fisheries & Seafood Exposition in China, and had no inhibitions about consuming cereal bars were selected. The questionnaire was composed of CATA choices that selected both the reasons for liking and disliking four different types of cereal bars, namely topokki flavor (hot pepper paste), seaweed flavor, kimchi flavor, and ginseng flavor cereal bars with 10% of dried anchovy content produced by BadaOne Co. (Seoul, Korea). The purpose of the study was to investigate Chinese consumer's attitudes and acceptance of different flavored cereal bars containing protein and calciumrich anchovy. For the selected Chinese customers, the acceptance score for the seaweed flavor was the highest, followed by topokki, red ginseng, and kimchi. The acceptance for the topokki flavor was higher than for seaweed for the attributes of color except for general acceptance, flavor, aroma, and texture. The results of the survey showed that the acceptance of kimchi was the lowest, contrary to earlier predictions. The results of the Check All That Apply (CATA) analysis showed that the reasons for liking the seaweed & anchovy flavor were the most diverse, and there was no reason chosen for disliking this flavor. The reasons for liking this flavor were listed as sweet flavor, healthy, seafood flavor, malty flavor, texture, new/unique, and umami. In the case of topokki and kimchi, the reason for disliking the flavor was umami, and in the case of red ginseng, the ginseng flavor was the reason for both likes and dislikes. CA analysis showed that both the flavor and emotional factors were positive for seaweed & anchovy and topokki, but negative for red ginseng. As a result, seaweed & anchovy flavor, which is familiar to the Chinese people, should be the first cereal bar considered for a launch.

This study aimed to investigate the physicochemical characteristics and antioxidant activity of cereal bars containing various concentrations (0, 10, 20, or 30%) of apple pomace (AP). Highest vitamin B₁ and C contents were observed in 30% AP-containing bars, but vitamin B₂ and B₃ contents were highest in the control (0.347 and 3.566 mg/100 g, respectively). Cutting strength decreased significantly in an AP concentration-dependent manner. Total polyphenol and flavonoid contents in 10% AP bars were 2.949±0.157 mg of GAE/g and 1.001±0.009 mg of CE/g, respectively. Antioxidant activities were assessed by measuring free radical scavenging activities, and 10% AP bars had the highest activities, as determined by ABTS (2,2'azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) and DPPH (α-α-diphenyl-β-picrylhydrazyl) assays (0.412±0.008 and 0.492±0.021 mg GAE/g, respectively). These results suggested that apple pomace should be regarded a potential nutritional and antioxidant source.

본 연구에서는 순환형 감압건조 및 초고압 추출공정을 이용하여 제조한 감귤농축액을 소비자의 건강과 편의성을 위해 첨가량을 달리하여 영양바에 적용 제조하여 품질특성을 알아보았다. 영양바의 색도에서 명도는 대조군이 72.3으로 가장 높았으며, 적색도는 15%와 20% 첨가군에서 2.7로, 황색도도 첨가량이 증가함에 따라 증가하는 경향을 나타내었다. 영양바의 pH는 대조군이 7.10, 첨가군이 6.57~6.97의 범위로 대조군의 pH 보다는 낮게 나타났다. 영양바의 경도는 감귤농축액이 증가함에 따라 감소하는 경향을 나타내었지만 유의적인 차이는 나타내지 않았다. 탄력 및 응집성은 감귤 농축액 증가에 따라 감소하였으며, 씹힘성은 대조군에 비해 감소하는 경향을 나타내었다. 영양바의 색의 기호도는 15% 첨가군이 가장 높게 평가되었으며, 향의 기호도는 20% 첨가군이 가장 높게 평가되었다. 맛에 대한 기호도는 15% 첨가군에서 높은 값을 나타내었다. 영양바의 조직감에 대한 기호도는 15% 첨가군에서 높은 기호도를 나타내었다. 전체적인 기호도는 15% 감귤농축액을 첨가한 영양바가 대조군보다 선호되는 것을 알 수 있었다. 상관관계에 대한 결과는 flavor에 대한 상관관계가 각 측정항목에 대해 우수하게 나타났다. 이상의 결과를 종합하여 감귤농축액 15% 첨가수준에서 영양바 제조 시 영양바에 대한 기호도를 높여줄 수 있을 것으로 판단된다.

This study evaluated the color, DPPH radical activity, and sensory characteristics of nutritional bars supplemented with varying concentrations (0, 2.5, 5, and 7.5%) of freeze-dried Natto. An inconsistent pattern was observed for the L value, whereas both a and b values increased significantly up to 5% addition of freeze-dried Natto. The DPPH free radical scavenging activity of nutritional bars supplemented with 0, 2.5, 5, and 7.5% freeze-dried Natto were determined to be 59.54, 59.70, 44.85, and 55.07%, respectively. The appearance, color, taste, texture, and overall preference of nutritional bars supplemented with freeze-dried Natto showed significant differences between the samples. The overall preference of the nutrient bar was highest at 6.08 points, determined for the 2.5% Natto supplemented bar. The quality characteristics of the 2.5% added samples exhibited significantly higher values as compared to the controls, thereby indicating the potential of development in health-functional cereal bars.

In this study, 230 female college students in Seoul area were surveyed to evaluate their eating habits and behavior, physical activities, and patterns of purchasing diet/low-calorie food. Their body composition was also determined using bioelectrical impedance(Inbody 520). The subjects were divided into two groups according to their BMI index with a mean BMI of 20.2$\pm$1.5(normal) weight and 25.0$\pm$1.7(obesity). Overall, 85.7% of the subjects reported that the food they purchase depends more on their preferences than the nutritional value of the food. When the two groups were compared there was no significant difference in the frequency or experience of purchasing diet-foods. Indeed, 69.3% of all female college students had purchased diet foods, and most consumed these foods 2~3 times a week. Obese group preferred a savory taste, while normal group preferred a sweet taste. The majority of the subjects(80.8%) answered that they "read nutritional labels carefully upon purchasing diet food", and that they examined calories(61.8%) and total fat(48.5%) most carefully. Of the types of low-calorie/diet foods purchased, beverages were the most commonly obtained; followed by noodles, diet-bars, and snacks. The most commonly purchased low calorie snacks were "potato-type C(hot-flavor)" and "potato-type A(salty-flavor)", while the most commonly purchased diet-bars were "low calorie-type A"(55.3%) and "high protein-bar"(32.3%). The most commonly purchased noodles were "thick noodle type"(65.1%), while the most commonly purchased drinks were "cereal tea"(65.1%) and "mixed herb tea"(66.0%). Overall, factors such as self-esteem or the degree of body satisfaction, rather than obesity(BMI index) itself, were significantly correlated with the frequency of purchasing diet-foods.
