The quality characteristics, total phenolic content, anthocyanin content, and DPPH radical scavenging activity of rice nutritional bar with added powder of aronia byproducts were investigated in this study. The rice nutritional bar was prepared by adding aronia byproducts powder at concentrations of 0%, 2%, 4%, and 6%. The pH of the rice nutritional bar batter was lowered for the control and 2% aronia byproducts powder was added. The moisture content, baking loss rate, leavening rate and specific volume of the rice nutritional bar decreased with as the aronia byproducts powder content increased. In relation to measurements of the colors of the rice nutritional bar crust and crumbs, as the content of aronia byproducts powder increased, the L and b values decreased while the a value increased. From texture analysis, the hardness and chewiness increased according to the level of added aronia byproducts powder, but the springiness and cohesiveness decreased. The total phenolic content, anthocyanin content, and DPPH radical scavenging activity showed the highest values in the rice bar with 6% aronia byproducts powder added. According to a sensory evaluation, overall preference was highest for the rice bar with 4% added aronia byproducts powder, whereas the color and taste was rated higher for the rice bar added with 4% and 6% aronia byproducts powder.

This study analyzed the quality characteristics of nutritional bars with varying concentrations (0, 0.5, 1.5, 2.5%) of Enteromorpha intenstinalis powder added. To achieve this, color analysis, an assessment of DPPH radical scavenging activities, and sensory evaluations were performed. The results revealed that as the amount of Enteromorpha intestinalis powder (EIP) increased, pH and lightness values decreased. DPPH radical scavenging activities of 75.26%, 56.11%, 71.59%, and 62.49% were exhibited for the 0%, 0.5%, 1.5%, and 2.5% concentrations, respectively at 50 mg/mL. Significant differences were observed between the samples with respect to the color, appearance, texture, taste, and overall preference for the nutritional bars. Overall preference was highest for the nutritional bar with 1.5% Enteromorpha intenstinalis powder added. Therefore, adding 1.5% of Enteromorpha intenstinalis powder to a nutritional bar is most suitable for enhancing preference and quality characteristics.

The purpose of this study was to investigate consumer preferred formats of nutrition labels: the type of nutritional information provided on the labels. A survey was conducted on 222 housewives between the age of 20 and 65 in Daejeon city in 1998, using an interview questionnaire showing illustrated nutritional label formats. Among twelve nutrients and caloric values listed on the nutrition labels, the housewives ranked their interest in the items in the following order of calorie (58.56%), calcium (56.76%), cholesterol (54.05%), protein (39.19%) and vitamin C (36.04%). The majority of the subjects (69.37%) checked labels when they bought milk or dairy products, whereas only 8.11% looked at labels when they bought Ramyon or noodles. Most of the subjects (90.99%) preferred products with labels with nutritional information as compared with products without labels. this was especially so true of the younger individuals and of pc-ople who checked food labels more frequently. The subjects preferred labeling which described the nutrient content per Package (55.41%), sewing size (32.88%) and food weight of 1009 (11.71%) as a standard nit. Generally, they prefer-red a simplified list to a detailed list of the number of nutrients, a figure graph to bar graph in nutrition claim, vertical bar graph to horizontal bar graph showing the nutritional content of foods and a web-type graphic format to a radiation-format when describing the item's percentage of the Korean RDA's nutrient content. The subjects who checked labels frequently especially preferred detailed list, while housewives with job or with unhealthy family members preferred a simplified list and graphic, rather than a numerical display. From this result, it is suggested that providing consumers with more nutrients information in a more easily understood graphic format would encourage the consumers to check nutritional labels. Therefore this should be considered when developing the regulations far nutrition labeling or when educating the Public about nutrition. (Korean J Community Nutrition 8(2) : 220∼230, 2003)

Background: Compliance with California's smoke-free restaurant and bar policies may be more a function of social contingencies and less a function of legal contingencies. The aims of this study were: 1) to report indications of compliance with smoke-free legislation in Korean bars and restaurants in California; 2) to examine the demographic, smoking status, and acculturation factors of who smoked indoors; and 3) to report social cues in opposition to smoking among a sample of Koreans in California. Materials and Methods: Data were collected by telephone surveys administered by bilingual interviewers between 2007-2009, and included California adults of Korean descent who visited a Korean bar or restaurant in a typical month (N=2,173, 55% female). Results: 1% of restaurant-going participants smoked inside while 7% observed someone else smoke inside a Korean restaurant. Some 23% of bar-going participants smoked inside and 65% observed someone else smoke inside a Korean bar. Presence of ashtrays was related to indoor smoking in bars and restaurants. Among participants who observed smoking, a higher percentage observed someone ask a smoker to stop (17.6%) or gesture to a smoker (27.0%) inside Korean restaurants (N=169) than inside Korean bars (n=141, 17.0% observed verbal cue and 22.7% observed gesture). Participants who smoked inside were significantly younger and more acculturated than participants who did not. Less acculturated participants were significantly more to likely to be told to stop smoking. Conclusions: Ten years after implementation of ordinances, smoking appears to be common in Korean bars in California.

Purpose: The aim of this study was to evaluate the quality characteristics of rice nutritional bars prepared by adding Chinese artichoke (CA) powder to the rice powder. Methods: CA rice nutritional bars were prepared with various levels of CA powder (0%, 5%, 10%, 15%, and 20%) and designated as CA0 (without CA powder), CA5, CA10, CA15, and CA20, respectively. The total phenolic content, DPPH free radical scavenging activity, moisture content, pH, baking loss rate, leavening rate, volume, color, texture analysis, and sensory evaluations of rice nutritional bars were performed. Results: The total phenolic content and DPPH free radical scavenging activity exhibited an increase with increase in the substitute amount of CA powder. The results showed that the pH of rice nutritional bars decreased in all sample groups as the content of CA powder increased. The volume of the sample group with CA powder was higher than that of CA0. As the content of CA powder increased, lightness of the rice nutritional bars crumbs decreased while redness and yellowness increased. The texture analysis of rice nutritional bars showed that hardness, gumminess, and chewiness were the highest in CA0 while springiness and cohesiveness were the lowest in CA0. With respect to characteristic intensity rating, the taste, flavor, and softness of rice nutritional bars increased with increasing amounts of CA powder. In terms of consumer acceptability, CA15 and CA20 received the highest scores with respect to texture. Conclusion: Therefore, the results of this study indicate that replacing 15% of the rice powder with CA led to an efficient enhancement in the antioxidant and nutritional values of rice nutritional bars as well as the sensory quality.

Purpose: This study was conducted to investigate the effect of cabbage powder on the quality characteristics of rice nutritional bars. Methods: In order to analyze quality characteristics, total phenolic content, DPPH free radical scavenging activity, baking loss rate, leavening rate, specific volume, moisture content, color, texture analysis, and sensory evaluations were assessed. Results: The total phenolic content and DPPH free radical scavenging activity of rice nutritional bars significantly increased with an increase in the content of cabbage powder (p<0.05). The baking loss rate, leavening rate, specific volume, and moisture content of the rice nutritional bars were significantly reduced as the amount of added cabbage powder increased (p<0.05). As the concentration of cabbage powder increased, the lightness and redness of the bars' crust and crumbs decreased, while yellowness increased (p<0.05). In texture analysis, the control bars showed the highest hardness values. Adhesiveness, springiness, and cohesiveness values slightly decreased with higher cabbage powder content in the groups with added cabbage powder (p<0.05). When consumer acceptability was measured, rice nutritional bars prepared with 15% cabbage powder showed the highest scores in color, whereas the rice nutritional bars prepared with 20% cabbage powder showed the lowest scores in flavor (p<0.05). In characteristic intensity rating, the taste and off-flavor of rice nutritional bars significantly increased with increasing amounts of cabbage powder (p<0.05). Conclusion: Judging from our results, it can be concluded that the addition of cabbage powder to rice nutritional bars during processing can enhance consumer preference for the bars, total phenolic content, and DPPH free radical scavenging activity.
