Process for making modified SOD wine

The present invention is method of producing modified SOD wine. The technological scheme of the present invention is that the modified SOD wine producing process includes the following steps: dissolving natural SOD inside sodium bicarbonate buffering liquid, dropping lauryl chloride, dropping sodium carbonate to maintain alkali, heating to react before cooling to room temperature, adding pre-cooled acetone, centrifuging to collect precipitate, dissolving the precipitate in double distilled water, centrifuging to obtain supernatant, chromatographic separation in glucosan gel column to collect active enzyme liquid, vacuum freezing to dry, dissolving in deionized water, adding into white spirit and bottling. The unique production process can obtain white spirit with SOD possessing long maintaining period and long half time in body.
