The present invention provides a superoxide scavenger comprising a
desirable material which is different from any conventional unstable
superoxide dismutase and is available at a low cost, and the present
invention also provides a beverage containing such a superoxide scavenger.
The superoxide scavenger and beverage of the present invention comprise a
composition extracted from a specific liquid. This specific liquid is
prepared by: boiling a grain with a liquid to obtain a grain liquor;
cooling the obtained grain liquor; adding a yeast into the cooled grain
liquor; leaving the grain liquor with the yeast while supplying oxygen
thereto; and sterilizing the resulting liquid by heating to obtain the
specific liquid.
