This study investigated the antioxidant activity of functional beverage concentrates containing herbal medicine extracts (FBCH) using various antioxidant assays, such as 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity, and reducing power assay. The total polyphenolic content of FBCH (81.45 mg/100 g) was higher than Ssanghwa tea (SHT, 37.56 mg/100 g). The antioxidant activities of FBCH showed 52.92% DPPH and 55.18% ABTS radical scavenging activities at 100 mg/mL, respectively. FBCH showed significantly higher antioxidant activities compared to the SHT (DPPH, 23.43%; ABTS, 22.21%; reducing power optical density; 0.23, P<0.05). In addition, intracellular reactive oxygen species generation significantly decreased in a concentration-dependent manner following FBCH treatment. These results suggest that the addition of herbal medicine extract contributes to the improved functionality of beverage concentrates.

The purpose of this study was to classify noodle meals into a few groups according to their menu patterns and cooking methods from the 318 noodles and Ttokgook menus of 360 elementary school foodservices around Busan and Gyeongnam province. Noodle meals with high frequency were also analyzed by season and region to give information for menu planning and to improve elementary school foodservices. The menus were collected from the internet(http://www.kdclub.com) and the home pages of elementary schools between December 2004 and September 2005. Taking all kinds of noodle meals together, the serving frequencies were significantly different among regions, but were not different from season to season. Three different menu patterns were revealed from the collected noodle menus. The most frequently served menu pattern was 'main dish+starchy food & dessert+fruit & beverage+kimchi'. Gooksu, Ttokgook, Udong, and Kalgooksu meals were served with this menu pattern. The menu pattern of Jajangmeon meal was 'main dish+side-dish+starchy food & dessert+fruit & beverage+(kimchi)'. For the Bibimmeon and the spaghetti meals 'main dish+soup+starchy food & dessert+fruit & beverage+kimchi' was used. Ttigim, Danmugy, Saengchae, and chicken were frequently selected as side dishes in the overall noodle menus. More side dishes of a wide variety were served in Ttokgook meal, whereas Danmugy was the most preferred food item as a side dish with Jajangmeon and Udong meals. Comdog, Mandu, Ttok, Matang, and doughnut were preferred food items as a 'starchy food & dessert' with most kinds of noodle meals, except spaghetti with which only garlic-bread was served. The fruit and beverage items were not different with the majority of noodle meals. These results suggest that cost food habits, compatible flavor combinations, and food preference of children rather than nutritional considerations contributed to the selection of food items for the components of noodle meals in the school foodservices.

The purpose of this study was to establish the best optimized extraction condition for the optimal development of fresh maca beverage using low temperature extraction and enzyme treatment. Low temperatures were applied to prevent heat-related nutritional loss during the extraction process. Best extraction conditions were investigated based on the ratio of maca to water, the ratio of enzymes, extraction temperature and time, and agitation. The optimal enzyme conditions were also examined after the treatment of cellulase:pectinase mixture to maintain the original color and flavor, as well as to increase the extraction yield. When cellulase:pectinase was 1:1, the extraction rate ranged from 77.84 to 79.29%. In addition, the best extraction rate was found when maca was mixed with twice volume of water and incubated at $45^{\circ}C$ ($84.05{\pm}0.32%$) with 90 rpm ($87.13{\pm}0.46%$) agitation for 3 hours ($84.73{\pm}0.29%$). Furthermore, sensory evaluation showed a high score in flavor, sweetness, and overall acceptability after adding 3% jujube concentrate into a fresh maca beverage.
