Abstract
In order to develop a new utilization method of mulberry leaf powder (MLP), this study tried to combine MLP with cocoa drink and measured antioxidant activity (AA) of combined sample solution expecting a synergistic effect. Contrary to expectation, AA of combined solutions was decreased with increasing in combined quantities of MLP by comparing with AA of each sample solution of MLP and cocoa drink. Reason of this result and effects of combination of MLP with cocoa drink on other functionalities are not yet known, so we cannot yet conclude whether this combination was not good.
