Abstract

This study was performed to evaluate the possible production of a functional beverage derived from abalone and with several plants (AP). Five types of AP composites were prepared having different medicinal plant compositions (AP-1 : abalone, garlic, jujube, Chinese matrimony fruit, dried orange peel, licorice root, zinger, honey; AP- II: abalone, garlic, black bean, Chinese matrimony fruit, cornus fruit, licorice root, zinger, honey; AP-III : abalone, jujube, arrow root, milk vetch, dried orange peel, licorice root, zinger, honey; AP-IV: abalone, black bean, arrow root, milk vetch, cornus fruit, liquorice root, zinger, honey; AP-V : abalone, garlic, Chinese matrimony fruit, milk vetch, licorice root, zinger, honey). In vitro analysis were performed to examine the antioxidant contents and alcohol dehydrogenase activities of the composites. AP-II had the highest total phenol contents (28.55±1.56 mg/100 g), and AP-V the highest level of flavonoids (47.61士1.58 mg/100 g). At 78.89土0.16%，AP-V displayed the strongest electron donating ability followed by AP-II(57.99土0.21%) and AP?I (37.66±0.20%). Reducing power was also significantly higher in AP-V. The Hydroxyl radical scavenging and SOD-like activities of all composites were less than 15% and 20%, respectively. At 12.5% alcohol concentration, ADH activity ranged from 114.47士2.18?121.39士4.36% and ALDH activity ranged from 100.04±2.90~129.54±4.80%; AP-1 , AP-II, and AP-V in 12.5% of alcoholic concentration. The composites of AP-1，AP-II，and AP-V, all containing garlic and Chinese matrimony fruit, were significantly stronger than AP-HI and AP-IV. Finally, also at 12.5% alcoholic concentration, the ALDH activity of AP-V was higher than its ADH activity.
