Cirsium setidens Nakai, a wild perennial, is widely consumed as a food and traditional medicine in Korea. In addition, diverse functionalities of C. setidens Nakai, including anti-inflammatory and antioxidant effects, have been reported. However, whether or not C. setidens Nakai and its major compound, pectolinarin have high nutritional value and functional properties remains unknown. This paper investigated the proximate compositions, mineral contents, hepatoprotective activities, hepatic fat accumulation inhibitory activities, and anti-inflammatory and anti-oxidant activities of C. setidens Nakai and its component parts, including of pectolinarin. The result showed that C. setidens Nakai and its major compounds have potential as a functional food material with natural antioxidant and anti-inflammatory activities.Key words: Cirsium setidens Nakai, nutritional components, antioxidant activity, pectolinarin, functional material
In order to increase the use of rice, ginseng Garaedduks and Topokki were made and the physicochemical and sensory properties were investigated. Topokki and Garaedduks were added with 0, 1, 3 and 5% ginseng powder and stored at 20 o C for 48 hours. The moisture contents were not different to the increasing amount of ginseng powder and increasing storage time for 48 hours. The moisture content of Garaedduks for control and 5% added ginseng powder were 48.08% and 49.62%, respectively. The L value in color of uncooked ginseng Garaedduk decreased according to the added amount of ginseng powder, and the b value in color increased significantly according to the added amount of ginseng powder and during 48 hours storage at 20 o C. Textural analysis, measured using a texture analyzer, of Garaedduk revealed that hardness, cohesiveness, chewiness decreased significantly and adhesiveness increased according to the added amount of ginseng powder. In sensory evaluation, 5% ginseng Garaedduk (uncooked, cooked) scored higher in overall acceptability than those of the other samples. In cooking properties, water absorption and solid contents increased according to the added amount of ginseng powder. Therefore, Garaedduk containing 5% ginseng powder was the most preferable. These results implied that the degree of retrogradation of ginseng Garaedduk might be low due to its high dietary fiber content.
This study was to investigate the quality characteristics of instant rice cake (Baekseolgi) with different concentrations of ginseng powder by molecular press dehydration (MPD) method. Baekseolgi was cooked using microwave oven, which is a useful cooking method because of reduced cooking time, even though it quickly takes moisture from food surface and lowers food quality. The result indicated that moisture content of Baekseolgi without ginseng powder was decreased; however, there was no significant difference in the Baekseolgi with ginseng powder with increased storage time for 24 hrs. The L value was decreased and a color value was increased with increasing concentrations of ginseng powder (p<0.05). There was no significant difference in the color values within the storage time. The hardness, gumminess, and chewiness of Baekseolgi without ginseng powder significantly changed as the storage time increased; in contrast, those of Baekseolgi with ginseng powder did not show such a significant change. The result of sensory evaluation showed that Baekseolgi with ginseng powder has higher scores in terms of color, flavor, taste, and overall acceptability than Baekseolgi without ginseng powder. Results of this study indicate the addition of ginseng powder to Baekseolgi improves moisture content, color value, and texture properties as well as sensory characteristics.
