Abstract
|
|
|
|
This work was a method that used an acid hydrolysis for increasing the efficacy of decreasing alcohol concentration from Hovenia dulcis extract. For acid hydrolysis, the best pH was 2.0 to obtain a maximum alcohol dehydrogenase activity at fixed reaction temperature and time. At pH 2.0, reaction temperature and reaction time 4 hr gave the highest activity which was of control. The bioactive compound, (+)-dihydromyricetin, content increased to after acid hydrolysis. This is very simple and efficient method to increase the efficacy of decreasing alcohol concentration from Hovenia dulcis extract.
