  • This study was carried out to optimize microencapsulation conditions for Inonotus obliquus extract powder with mediumchain triacylglycerol (MCT) using response surface methodology (RSM), and to determine the possibility of adding encapsulated I. obliquus extract to milk toward improving the functionality of milk. and to investigate the effects of added encapsulated I. obliquus extract on the physicochemical and sensory properties of the product. The microencapsulation efficiency of I. obliquus extract powder was investigated with respect to three variables (ratios of core material to coating material, amounts of water added, and spray pressure) in RSM. The optimal conditions for microencapsulation of I. obliquus extract powder were obtained from the ratio of core material to coating material (2.92:10) and the amount of water added (0.5 mL); the spray pressure had an insignificant effect on the microencapsulation (p<0.05). Adding encapsulated I. obliquus extract into milk did not significantly affect either color (L, a and b values) or thiobarbituric acid (TBA) values. Sensory test revealed that there were significant improvements in brownish, herb flavor, and bitterness scores for encapsulated I. obliquus extract-added milk as compared with those for uncapsulated I. obliquus extract-added milk. Based on the data obtained from the present study, it is concluded that microcapsules of I. obliquus extract powder could be applicable to milk without remarkably adverse effects on physicochemical and sensory properties

For all experiments with Chinese noodles, the grape peels were frozen and dried, powdered, and filtered with a 150-mesh strainer. The grape-peel powder, was added to the composite flour in a proportion of 0%, 1%, 3%, 5%, and 7%. The color of the cooked noodle appeared brown, demonstrating that the L-value decreased as the amount of grape-peel powder increased. The value of a, which corresponds to the level of redness, increased and the cooked noodle appeared brown as the amount of grape-peel powder added increased. The yellowness of the cooked noodle tended to decrease as the value of b, which corresponds to the level of yellowness, gradually (p<0.05). In the texture analysis, hardness was highest in the 7% grape-peel powder group, while the 5% groups showed the highest springness values. The 1% groups showed the highest cohesivness while the 7% groups were the chewiest. The 7% groups had the lowest stickiness values (p<0.05). It terms of sensory quality, the overall surface color, texture and taste were perceived as superior for the 3% grape-peel powder-added groups and lowest for the 7% group (p<0.001). The 3% treatment showed the best overall quality.

  • Purpose: In order to develop soy sauce and increase its functionality, by adding black garlic extract. Methods: We compared quality characteristics and antioxidant activity of 20 days aging black garlic soy sauce from mixed manufacturers with raw soy sauce (commercial fermented soy sauce) and different ratio of black garlic extract (65 Brix, 0.3-5.0%). Results: The salt content of the black garlic extract (0.3-5.0%) added soy sauce were 12.35-12.77%. The pH was lowered to 4.99, and acidity was increased to 2.12%, depending on the increase in black garlic extract added ratio. The crude protein and total nitrogen contents were 6.23-6.62% and 1.10-1.16%, respectively, and content of amino form nitrogen was 0.52-0.53%, without significant differences between experimental groups. Contents of reducing sugar and free sugars (fructose and glucose) tended to be higher with higher mixing ratios of black garlic extract. Total phenolic compounds and flavonoids contents were significantly increased in the 3% and 5% black garlic extract addition group. At concentrations of 62.5, 125, 250, 500, 1,000 and $2,000{\mu}g/mL$, the DPPH and ABTS radical scavenging activity of the polysaccharides isolated from control soy sauce and 5% black garlic extract added soy sauce showed higher correlation with their concentration. Conclusion: These results, confirmed that the soy sauce produced by adding more than 3% of black garlic extract has high antioxidant activity.

  • These days a great mix of traditional and digital contents such as movie, broadcasting, advertisement, e-books, music, game, animation, cartoon, character, knowledge information, and art performance are widely available. Many more are yet to come, with improved quality and added features. It is expected that all these contents will be evolved into a new breed of convergence content through the process of consolidation, expansion, integration, and recreation. Across the digital ecosystem, a new formula is being added to the industrial structure : 'Information/Content-Platform/Device-Goods/Service.' In the near future, as a result of technological innovation and convergence, the business sector will lose its boundaries as well, as businesses will be forced to look beyond the product itself and focus more on multi-functionality. Especially, in the era of creative economy, more policies need to be crafted in order to procure a new growth engine for the future with the agenda for convergence between humanities and technology. Therefore, the purpose of this paper is to analyze the concept, factors, elements, types, and cases of convergence, which are the essence of content convergence. This analysis, with its focus on the convergence process, will help identify the effects and limits of content convergence as well as the prospects for convergence contents in the smart ecosystem under the creative economic system.

  • The new version of sikhye(sweet rice drink) was prepared by adding sweet pumpkin (SP) in order to improve customers' preferences for sikhye by modifying the color, and flavor, as well as health functionality. The independent variables were sweet pumpkin amount(0, 2, 4, 6, and 8% malt powder extract) and storage periods(0, 3, 6, 9, and 12 days). Each sample was measured by using physicochemical and sensory evaluations, and results were statistically tested to examine significant differences among samples. pH increased with higher amounts of added pumpkin. As additional levels of sweet pumpkin increased, the Hunter's L value decreased, whereas the b value increased. In a consumer acceptance test, all characteristics except for sweetness were significantly different at p<0.05. The overall acceptability, including yellowness, malt aroma, and sweetness in the pumpkin added sample was estimated to be better than the comparative sample was. There was no significant difference between SP4, SP6, and SP8, but SP2 showed a lower preference than other samples.

  • This paper intends to improve caddies' vocational efficiency, to increase the quality of caddies' services for customers, and further, to widen the application of smart clothes by proposing prototypes of smart uniforms in which caddies' vocational characteristics are reflected. The smart uniforms proposed by this study were restricted to those for spring and fall seasons and three types for a jacket, a turtle neck shirt, pants, and a jumper were proposed. Each design was developed to contain functionality and aesthetic, and also to be transformed subject to weather or other conditions. In addition, the uniforms were designed to carry not only a two-way radio and a remote controller for a cart that caddies necessarily carry, but also i-Pod, a distance meter, and other digital tools by use of solar cells. That is, this paper proposed the designs that can meet with caddies' vocational characteristics and different conditions. This paper is regarded meaningful in that smart clothes, which are forecasted as a future high value-added business, are applied to the uniforms of various job types so they can expand me existing functions of uniforms and further, think about the ways of being used for higher value-added products through the fusion with technologies.
